An FIBC bag RFQ should do more than state a bag size, capacity, and required quantity. It should explain what the bag will contain, how it will be filled and discharged, where it will be used, which risks must be controlled, and what evidence the supplier must provide.
Without this information, different suppliers may quote different fabrics, liners, lifting systems, safety classifications, packing methods, or compliance scopes. The resulting prices may look comparable even though the proposed bags are not.
A well-prepared RFQ gives an FIBC manufacturer enough information to:
Understand the product and application
Calculate the required volume
Select an appropriate construction
Match the bag to existing equipment
Address leakage, moisture, hygiene, and electrostatic risks
Identify applicable testing and documentation
Estimate realistic packing and freight quantities
Declare deviations instead of making silent assumptions
This guide explains what buyers should include when requesting quotations for standard or custom FIBC bags, and provides a reusable RFQ template at the end.
At minimum, an FIBC bag RFQ should include:
RFQ section | Minimum information |
|---|---|
Product | Product name, physical form, bulk density, particle characteristics, hazard status, and sensitivity |
Payload | Target fill weight, maximum net weight, and filling variation |
Bag size | Required dimensions or available pallet, container, and equipment constraints |
Service category | Single-trip or planned reuse, SWL, and required safety factor |
Filling | Filling equipment, connection dimensions, fill rate, dust control, and preferred top |
Discharge | Discharge method, equipment connection, flow requirements, and preferred bottom |
Handling | Forklift, crane, hoist, or stevedore handling and required loop arrangement |
Protection | Coating, liner, sift-proof seams, barrier, UV, and contamination-control needs |
Safety | Electrostatic environment, dangerous-goods status, food-contact requirements, and other regulated uses |
Identification | Printing, label, barcode, document pouch, language, and traceability fields |
Quality evidence | Required drawings, test reports, declarations, inspection records, and shipment documents |
Packing | Bags per bale or pallet, pallet requirements, container type, and delivery condition |
Commercial information | Quantity, annual demand, price tiers, currency, delivery term, destination, and required date |
Supplier response | Compliance, deviations, alternatives, exclusions, lead time, validity, and one-time charges |
These fields form the minimum framework. The level of detail should increase when the product is hazardous, moisture-sensitive, contamination-sensitive, electrostatically hazardous, unusually dense, abrasive, or difficult to discharge.
A common RFQ begins with wording such as:
Please quote 1,000 kg PP jumbo bags, 90 × 90 × 120 cm, 160 GSM.
This appears specific, but it does not explain whether the proposed bag can perform in the buyer’s process.
The supplier still does not know:
What product will be filled
Whether 1,000 kg is the target or maximum payload
How the dimensions were selected
Whether the product will reach the required weight within that volume
Whether it can leak through fabric or seams
Whether it absorbs moisture
Whether the filling process generates static electricity
Whether the bag will be stacked
Whether the bag is intended for one filling or repeated use
Whether the contents are dangerous goods
Whether food-contact controls are required
How the bag connects to the filling and discharge equipment
An effective RFQ starts with the required result. Construction details can then be divided into three categories:
Mandatory requirements: Features that must not change because of equipment, safety, approval, or customer requirements.
Preferred requirements: The buyer’s current design or preferred arrangement, for which alternatives may be considered.
Supplier-designed requirements: Details the supplier may propose based on performance, testing, and manufacturing capability.
This approach gives the supplier room to engineer an appropriate bag without allowing important requirements to become optional.
Every RFQ should have a unique identity.
Include:
Buyer company and contact
RFQ number
RFQ title
Issue date
Revision number
Quotation deadline
Project or customer reference
Individual line-item number for each bag
List of attached drawings and documents
Confidentiality requirements
Required language and units
If the RFQ is revised, issue a new revision rather than replacing the original file without notice. Include a short revision history showing what changed.
For example:
Revision | Date | Change |
|---|---|---|
Rev. 0 | 10 August | Initial issue |
Rev. 1 | 14 August | Updated bulk density and filling-spout diameter |
Rev. 2 | 18 August | Added liner and food-contact documentation requirements |
Ask suppliers to state the RFQ revision used in their quotation. Otherwise, one supplier may quote the original specification while another prices a later version.
If a requirement remains undecided, mark it as TBD, supplier to propose, or quotation option required. Do not leave an empty field that could be interpreted as “not required.”
The product influences nearly every part of an FIBC design. Its identity should therefore be the first technical section of the RFQ.
State:
Commercial or technical product name
Chemical name where relevant
Powder, granule, flake, pellet, crystal, or paste
Homogeneous material or mixture
Whether the product can separate during handling
Whether the bag will contain one product or several product grades
If the exact formulation is confidential, provide the properties needed for bag selection. A safety data sheet may be shared under an appropriate confidentiality arrangement.
Do not use descriptions such as “chemical powder,” “food material,” or “mineral” without further information. Products within the same industry can have very different density, flow, abrasion, moisture, and electrostatic characteristics.
Provide the bulk density in kg/m³ or lb/ft³ and explain how it was measured.
Where relevant, provide:
Aerated or loose bulk density
Filled bulk density
Settled bulk density
Expected density range
Density after transport or vibration
A single average value may be insufficient when the product changes volume significantly during filling or shipment.
The approximate product volume can be calculated as:
Product volume = net fill weight ÷ bulk density
For example, 1,000 kg of material at 650 kg/m³ requires approximately:
1,000 ÷ 650 = 1.54 m³
This is the volume occupied by the product under the stated density condition. The selected bag may need additional space for filling profile, headspace, aeration, closure, settlement, and safe handling.
Include relevant information about:
Particle-size range
Percentage of very fine particles
Shape of particles
Dustiness
Abrasiveness
Sharp or angular particles
Flowability
Angle of repose
Bridging or rat-holing tendency
Tendency to compact
Tendency to cake or form lumps
Adhesion to plastic surfaces
Presence of oils or other process residues
These properties affect fabric selection, seam treatment, liner design, outlet size, reinforcement, and discharge performance.
A supplier cannot evaluate sift-proofing from bulk density alone. Fine powder can escape through sewing holes or fabric interstices even when the bag is mechanically strong.
State whether the product is sensitive to:
Moisture
Oxygen
Light
Odor transfer
Contamination
Microbial exposure
Metal particles
Foreign material
Temperature
Static electricity
Loss of volatile components
Describe the required outcome rather than using an undefined term such as “moisture-proof.” For example, explain the storage duration, climatic exposure, acceptable moisture gain, and whether an inner liner or higher-barrier material has already been validated.
State:
Product temperature at filling
Maximum expected temperature
Whether the product cools inside the bag
Ambient operating-temperature range
Cleaning or sterilization exposure, if applicable
Known compatibility concerns with polypropylene, polyethylene, coatings, inks, thread, or additives
A bag qualified for an ambient-temperature powder should not automatically be assumed suitable for a warm, chemically aggressive, or solvent-contaminated product.
The RFQ should distinguish the normal target weight from the maximum load the bag may contain.
Provide:
Target net fill weight
Minimum acceptable fill weight
Maximum possible fill weight
Filling-system tolerance
Required Safe Working Load
Whether gross or net weights are being used
Single-trip or reusable service
Required safety factor
Expected number and type of handling stages
For example:
Target fill weight: 975 kg
Filling tolerance: ±15 kg
Maximum possible net weight: 990 kg
Required SWL: 1,000 kg
Service: Single-trip
Safety factor: 5:1
The filling process must remain within the marked SWL. The safety factor must not be used as an allowance for overfilling.
Under ISO 21898:2024 for non-dangerous goods, a 5:1 FIBC is a single-trip bag intended for one filling. A 6:1 bag is a standard-duty reusable FIBC intended for a controlled, limited number of fillings and discharges. Dangerous-goods approval is a separate requirement.
If reuse is planned, explain:
Intended contents during every use
Expected return route
Inspection responsibility
Cleaning method
Traceability system
Rejection criteria
Storage between uses
Maximum planned service period
Writing only “reusable bag required” does not provide enough information to determine whether a controlled reuse system is practical.
An RFQ can either specify the finished bag dimensions or provide the constraints from which the supplier should propose them.
State:
Body width
Body length or depth
Body height
Overall height where critical
Required tolerance for each critical dimension
Whether dimensions are internal, external, finished, or laid flat
Whether the dimensions include the top, bottom, or lifting loops
Designed filling height
Required filled footprint
Use one unit system consistently. If both metric and imperial units appear, identify which is controlling.
Provide:
Pallet length and width
Maximum filled overhang
Maximum filled height
Bags per pallet
Pallet material and rating
Stretch wrapping or securing method
Whether the bag must remain within a pallet footprint
Maximum gross pallet weight
Rack, floor, or warehouse constraints
A bag can match its empty dimensions yet bulge beyond the pallet after filling. If a square filled profile is necessary for space utilization or stability, specify the required filled footprint and loading objective rather than requesting a baffle construction without explanation.
State:
Container or truck type
Internal height restrictions
Door-opening restrictions
Required bags per container or vehicle
Maximum permitted gross mass
Loading orientation
Palletized or floor-loaded shipment
Required stacking arrangement
Unloading equipment at destination
The supplier should not guarantee a container quantity from nominal empty-bag dimensions alone. Filled shape, packing arrangement, product settlement, pallet height, legal weight limits, and loading trials may all affect the actual quantity.
The top of the bag must fit the filling process, not simply match a standard catalog option.
Include:
Type of filling machine
Drawing or photograph of the filling head
Filling-head outside diameter
Clamping method
Available vertical clearance
Filling rate
Air entrainment or aeration
Dust-extraction connection
Weighing method
Product temperature
Operator access
Whether the bag is supported or inflated before filling
Required closure method
Possible top constructions include:
Open top
Full duffle or skirt top
Filling spout
Conical top
Top flap
Specialized closed-filling connection
When a filling spout is required, specify:
Spout diameter or circumference
Spout length
Required tolerance
Coated or uncoated fabric
Closure tie or cord
Dust-control requirement
How the dimension is measured
Required connection to the filling head
A statement such as “standard filling spout” can lead to poor clamping, dust release, slow changeover, or operator modification at the filling line.
The RFQ should describe how the contents will leave the bag.
Include:
Gravity discharge, controlled discharge, or destructive opening
Discharge equipment
Outlet connection dimensions
Required discharge rate
Acceptable residual product
Dust-containment requirement
Flow-aid equipment
Access available to the operator
Need to stop and restart flow
Whether the bag will be reused
Cleaning or contamination concerns
Whether the liner must discharge with the product or remain secured
Possible bottom designs include:
Flat bottom
Plain discharge spout
Spout with flap
Spout with petal closure
Spout with star closure
Conical bottom
Full-open bottom
Specialized controlled-discharge design
For a discharge spout, state:
Diameter
Length
Closure type
Number and position of ties
Required protective flap
Equipment interface
Required tolerance
Product flow information is essential. A narrow outlet may be satisfactory for free-flowing pellets but unsuitable for cohesive powders. Increasing the outlet diameter may not solve bridging if the bag, liner, support frame, and discharge equipment are not considered together.
State every planned handling method from filling through final discharge.
Include:
Forklift
Crane
Hoist
Single-point lift
Stevedore handling
Pallet movement
Suspended discharge frame
Manual positioning of empty bags
For forklift handling, provide:
Fork-tine length
Fork-tine width and thickness
Distance between tines
Maximum lifting height
Available overhead clearance
Whether the operator can access all four loops
Any automatic loop-engagement requirement
For the bag, specify or request a proposal for:
Number of lifting loops
Cross-corner or side-seam arrangement
Loop material
Free loop height
Loop width
Loop color
Stevedore straps
Protective sleeves
Reinforcement
Required lifting configuration
If the bag must be lifted by one or two points, say so explicitly. A standard four-loop bag should not be treated as a single-point lifting bag merely because a site prefers faster handling.
The supplier should also know whether the filled bag will be repeatedly lifted during one filling cycle. Multiple handling stages do not make a single-trip bag reusable, but they can affect the operational review and trial plan.
If the buyer has an approved design, list its construction as a controlled requirement. If not, describe the required performance and allow the supplier to propose a suitable structure.
Possible constructions include:
U-panel
Four-panel
Circular or tubular
Baffle or Q-bag
Single-loop or two-loop
Specialized form-stable construction
Relevant fabric information may include:
Woven polypropylene material
Virgin or permitted recycled content
Fabric weight
Coated or uncoated fabric
Coating weight
Fabric color
UV stabilization
Tensile and elongation requirements
Weave or tape requirements
Conductive or dissipative components
Required product-contact material
GSM should not be used as the only indicator of performance. The complete bag includes the body fabric, loops, reinforcement, thread, seams, coating, liner, dimensions, and manufacturing controls.
If suppliers may optimize the construction, write:
Supplier may propose fabric weight and construction, provided the complete FIBC meets the specified SWL, service category, dimensions, application requirements, and test evidence. All proposed values and deviations must be stated.
This is clearer than copying a GSM value from an old bag whose original design basis is unknown.
For powders and small particles, describe the required level of containment.
Include:
Particle-size distribution
Percentage of fines
Dustiness
Acceptable product loss
Cleanliness requirements for the container or warehouse
Whether external dust contamination is acceptable
Filling and discharge pressure conditions
Need for coated fabric
Need for sift-resistant seams
Need for filler cord, felt, tape, or other seam treatment
Need for a liner
Required validation method
Avoid relying on phrases such as “dust-proof” or “leak-proof” without defining the test condition. A sewn woven bag contains needle holes and construction joints. Performance should be evaluated using the actual or representative product under realistic filling, handling, and discharge conditions.
If zero visible residue outside the bag is a critical acceptance criterion, state where and how it will be inspected during a trial.
“PE liner included” is not a complete liner specification.
The RFQ should explain why the liner is required:
Moisture protection
Oxygen protection
Product containment
Contamination control
Chemical compatibility
Odor control
Electrostatic performance
Clean discharge
High-purity application
Barrier protection during a defined shelf life
Then define or request a proposal for:
Liner material
Film structure
Thickness and tolerance
Color
Tubular, form-fit, baffle, or shaped design
Loose, glued, tabbed, sewn, or otherwise attached
Top and bottom configuration
Filling and discharge connections
Perforated or non-perforated construction
Sealing method
Food-contact status where applicable
Electrostatic classification or compatibility where applicable
Required oxygen or water-vapor barrier performance
Dimensional fit
Prevention of liner collapse, tearing, or discharge blockage
Traceability and inspection
The liner must be evaluated as part of the complete system. A conductive or dissipative outer bag can be compromised by an incompatible liner, label, or document pouch. A very loose liner may also interfere with discharge even if its film provides the required barrier.
The RFQ should not ask for Type A, B, C, or D solely on the basis of the product name.
Provide the available process-safety information, including:
Whether the product can form a combustible dust cloud
Minimum ignition energy, if known
Whether flammable gases or vapors may be present
Presence of flammable solvents
Internal and external atmosphere
Hazardous-area classification
Filling and discharge rate
Earthing availability
Grounding verification process
Process temperature and humidity
Liner requirements
Other components placed inside or on the bag
Applicable plant or customer safety assessment
The buyer’s qualified safety team should determine the required electrostatic control approach. The supplier should then confirm that the complete bag, liner, label, document pouch, and conductive components are compatible with that requirement.
For Type C FIBCs, the RFQ should define the grounding connection and site grounding procedure. For any electrostatic classification, request applicable test evidence for the quoted construction rather than accepting a generic statement in a catalog.
Mechanical safety factor and electrostatic classification are separate. A 6:1 bag is not automatically electrostatically safe.
If the contents are regulated as dangerous goods, the RFQ must provide more than the phrase “UN bag required.”
Include, as applicable:
UN number
Proper shipping name
Hazard class and subsidiary risk
Packing group
Physical form
Maximum net quantity
Applicable packing instruction
Required flexible IBC code
Transport modes
Origin, destination, and transit jurisdictions
Special provisions
Competent-authority requirements
Required UN marking
Required design-type test evidence
Required manufacturing and inspection records
The supplier must evaluate the requested bag against the exact dangerous-goods classification and transport route. A commercially rated 6:1 bag is not automatically approved for dangerous goods.
Buyers requesting UN-certified FIBCs should require the supplier to identify the approved design type, manufacturing site, maximum permissible load, packing-group suitability, test reference, and completed marking.
If the classification is still being confirmed, state that the quotation is preliminary and cannot be approved for dangerous-goods use until the regulatory information is complete.
“Food grade” can mean different things to different suppliers. The RFQ should identify the required materials, manufacturing environment, hygiene controls, and evidence.
Include:
Direct or indirect food contact
Product-contact surfaces
Destination market
Applicable buyer or customer specification
Required food-contact declarations
Migration or composition evidence
Virgin-material requirements
Additive, ink, thread, and liner restrictions
Cleanliness level
Cleanroom or controlled-environment requirement
Pest-control expectations
Foreign-material control
Metal-detection requirement
Air cleaning or vacuum cleaning
Light-table inspection
Personnel-hygiene controls
Allergen-control requirements
Odor requirements
Microbiological limits, where justified
Lot traceability
Packaging used to protect empty bags
Required audit or management-system certification
Do not assume that a facility certificate alone confirms that every material in the quoted bag meets the buyer’s product-contact requirements. Ask for evidence that applies to the body fabric, coating, liner, thread, ink, ties, labels, and other relevant components.
Pharmaceutical applications may also require controlled change notification, approved suppliers, defined contamination controls, retained records, and customer audit rights. These requirements should be written into the RFQ rather than discussed after the price has been accepted.
Explain what the empty and filled bags will experience.
Include:
Indoor or outdoor storage
Expected outdoor exposure
Geographic or climatic conditions
Temperature range
Relative humidity
Direct sunlight
Rain or standing water exposure
Storage duration
Transport duration
Stacking duration
Contact with soil, pallets, or rough surfaces
Required shelf-life conditions for empty bags
Required UV stabilization or test evidence
Restrictions on recycled content or disposal
Sustainability reporting requirements
An FIBC should not be described as “weatherproof” without defining the expected exposure. Coated fabric and a liner may improve resistance, but seams, closures, condensation, and prolonged outdoor storage still require consideration.
If outdoor storage cannot be avoided, ask the supplier to state the protection limits and required storage instructions.
Safety factor does not determine stack height. The RFQ must state stacking separately.
Include:
Whether stacking is permitted
Filled bags in each stack
Palletized or non-palletized stacking
Storage duration
Warehouse floor condition
Product settlement
Required filled footprint
Maximum stack height
Dynamic transport stacking, if applicable
Required compression or stacking evidence
Whether the bags must be self-supporting after filling
Whether a baffle design is being considered
Do not request “six-high stacking” merely because a bag has a 6:1 safety factor. Filled stability, compression performance, product behavior, pallet condition, and handling method must be evaluated independently.
Where container utilization is important, request a filling and loading trial using the intended product or a representative material. A baffle bag may improve the filled shape, but the benefit depends on product flow, fill height, bag dimensions, and loading arrangement.
Provide controlled artwork or a clear printing schedule.
State:
Number of printed panels
Number of colors
Print dimensions and position
Ink restrictions
Artwork file format
Required proof and approval process
Product name
Product code
Net and gross weight fields
Lot or batch field
Manufacturing date
Handling instructions
Warning statements
Country of origin
Customer or regulatory marks
Barcode or QR code
Required languages
Label material and size
Label position
Document pouch size and location
Durability and legibility requirements
Also list accessories such as:
Document pouch
Colored loops
Closure ties
Grounding tabs
Protective flaps
Lift-loop sleeves
Pallet
Dust cover
Outer protective wrapping
The approved artwork should have its own file name and revision. Avoid sending label text only through email or messaging applications without connecting it to the controlled RFQ.
The RFQ should identify what evidence must be reviewed before ordering and what must accompany each shipment.
Possible requirements include:
Technical drawing
Complete specification sheet
Compliance matrix
Material data
Type-test report
Cyclic top-lift test evidence
Compression or stacking test evidence
Electrostatic test report
UN design-type approval and test evidence
Food-contact declarations
Management-system certificates
Manufacturing-site information
Sample inspection report
Proposed label artwork
Deviations and exclusions
Possible requirements include:
Certificate of conformity
Certificate of analysis where applicable
Lot inspection report
Dimensional inspection
Fabric and loop test results
Traceability records
Metal-detection or cleanliness records
Packing list
Container-loading photographs
Country-of-origin document
Shipment sample or retained sample
Approved deviation record
For every requested document, state:
Whether it is required with the quotation, sample, order, or shipment
Whether a generic certificate is acceptable
Whether it must identify the manufacturing site
Whether it must reference the bag drawing and revision
Required language
Required retention period
A test report is useful only when it can be connected to the quoted construction. SWL and safety-factor values alone do not prove that the report covers the proposed dimensions, fabric, loops, seams, liner, and production site.
The RFQ should explain how the proposed bag will be approved.
Possible stages include:
Supplier drawing review
Material-document review
Unprinted prototype
Printed pre-production sample
Filling trial
Lifting and handling trial
Discharge trial
Pallet or container-loading trial
Laboratory or compliance review
Pilot production order
Final specification release
State:
Number of samples required
Whether samples are free or chargeable
Who pays freight and testing
Product used for the trial
Acceptance criteria
Required trial data
Approval authority
Retained master-sample requirements
Whether mass production may begin before written approval
How changes after approval will be controlled
“Same as sample” should not replace a drawing and written specification. Samples may age, become damaged, or contain features that cannot be measured reliably. If an existing bag is supplied as a reference, give it a sample ID and explain which characteristics must be duplicated.
The approved sample, drawing, specification, artwork, and test evidence should form one controlled approval package.
Suppliers need sufficient commercial information to calculate production and delivery accurately.
Include:
Sample quantity
Trial-order quantity
Initial production quantity
Annual forecast
Expected order frequency
Required price-break quantities
Acceptable MOQ
Currency
Required quotation validity
Required delivery date
Delivery schedule
Partial-shipment requirements
Destination
Incoterms® rule, edition, and named place
Payment-term request
Required warranty or claim terms
Required spare quantity or overrun limit
For example:
Quote FCA Nanjing, China, Incoterms® 2020, and DAP buyer’s warehouse, Rotterdam, Netherlands, Incoterms® 2020, as separate options.
Naming only “FOB,” “CIF,” or “DAP” is incomplete. The named port, place, terminal, or address is necessary to establish the quotation scope.
Ask the supplier to list separately:
Sample charges
Printing-plate charges
Artwork charges
Setup charges
Testing charges
Inspection charges
Pallet charges
Document charges
Tooling charges
Freight
Conditional surcharges
This section gives the supplier the basis for a complete quotation. Detailed price normalization and supplier scoring should take place after technically responsive quotations have been received.
The way empty bags are packed affects cleanliness, freight cost, storage, and production-line handling.
State:
Folded dimensions
Folding orientation
Required number of bags per bale, carton, or pallet
Bale wrapping
Inner protective packaging
Pallet dimensions
Pallet material
Maximum pallet height
Maximum pallet gross weight
Edge or moisture protection
Shipping marks
Container type
Floor-loaded or palletized shipment
Maximum handling-unit weight
Required unloading method
Storage restrictions on arrival
Ask the supplier to confirm:
Bags per bale
Bales per pallet
Pallets or bales per container
Pack dimensions
Gross and net packing weight
Estimated shipment volume
Pallet treatment documentation where applicable
Do not accept a container quantity without understanding the packing basis. A quotation for 10,000 bags floor-loaded in compressed bales is commercially different from one for 10,000 bags packed on pallets with protective cartons.
The RFQ should tell the supplier how to respond.
A useful compliance matrix contains:
RFQ requirement | Buyer requirement | Supplier response | Status | Deviation or evidence |
|---|---|---|---|---|
SWL | 1,000 kg | 1,000 kg | Comply | Test report TR-XXX |
Safety factor | 5:1 | 5:1 | Comply | Single-trip design |
Body width | 95 cm ±2 cm | 95 cm ±2 cm | Comply | Drawing DR-XXX |
Liner thickness | 80 μm minimum | 70 μm proposed | Deviates | Price and performance option attached |
Delivery | 30 days from approved artwork | 35 days | Deviates | Material procurement included |
Use defined status terms:
Comply
Deviates
Alternative proposed
Clarification required
Not included
Require the supplier to:
Complete every line
Identify assumptions
List exclusions
Describe proposed alternatives
State the manufacturing site
Reference supporting documents
Confirm the RFQ revision
State quotation validity
Identify all one-time charges
Explain what starts the lead time
Obtain written approval before changing the quoted design
A blanket statement such as “fully compliant” is not a substitute for a completed response.
Please quote 10,000 one-ton big bags, 90 × 90 × 120 cm, with liner and printing. FOB price required.
This request leaves the supplier to guess the product, volume, SWL, safety factor, liner, filling connection, discharge design, printing scope, compliance requirements, packing, and named port.
Quote 10,000 single-trip FIBCs for 950 kg of non-dangerous mineral powder. Maximum possible fill weight is 980 kg; required SWL is 1,000 kg and SF is 5:1. Aerated bulk density is 620 kg/m³ and settled bulk density is 690 kg/m³. Particle size is 10–300 μm, with approximately 15% below 45 μm. The product is abrasive, dusty, non-hygroscopic, and filled at less than 40°C.
The bag must fit a 1,000 × 1,200 mm pallet without filled overhang. Supplier should propose the body dimensions and state the expected filled footprint. Filling is through a 400 mm outside-diameter filling head with pneumatic clamping and dust extraction. Gravity discharge is through a 350 mm receiver connection.
Quote a filling spout and a discharge spout with protective flap. Propose fabric, coating, sift-resistant seams, and liner construction suitable for the product. The liner is required for fine-powder containment and must remain secured during discharge.
Bags will be handled by forklift using all four loops and will not be refilled after discharge. No combustible atmosphere or dangerous-goods classification applies. Two-color printing is required on two panels according to Artwork Rev. 1.
Provide the drawing, specification, type-test evidence, packing plan, compliance matrix, sample cost, production MOQ, lead time, and price for 10,000 and 25,000 bags. Quote FCA supplier facility and DAP buyer warehouse under Incoterms® 2020, with the exact named places stated.
This version still allows the supplier to propose technical details, but it defines the performance, equipment, approval, and commercial boundaries needed for a meaningful quotation.

Before issuing the RFQ, confirm:
The RFQ has a unique number, date, and revision.
Every bag design has its own line-item number.
The product and its physical form are identified.
Aerated, filled, or settled bulk density is clearly distinguished.
Particle size, flow, dust, abrasion, and sensitivity are described.
Target and maximum fill weights are separated.
SWL and service category are stated.
Bag dimensions or equipment and pallet constraints are provided.
Filling equipment and connection dimensions are included.
Discharge equipment and flow requirements are included.
Every planned lifting method is identified.
Mandatory construction requirements are separated from supplier-designed details.
Leakage and sift-proofing expectations are defined.
The liner is specified by function and construction, not only as “PE.”
Electrostatic information covers the product, atmosphere, process, and liner.
Dangerous-goods information is complete where applicable.
Food-contact and hygiene requirements identify the destination market and evidence.
Storage, UV exposure, temperature, and stacking conditions are stated.
Artwork, labels, and accessories are controlled.
Pre-order and shipment documents are listed separately.
Sample, trial, and approval stages are defined.
Empty-bag packing and container assumptions are provided.
Quantity, currency, delivery term, edition, and named place are stated.
Suppliers must list deviations, alternatives, assumptions, and exclusions.
Suppliers must connect their evidence to the quoted design and manufacturing site.
Unresolved fields are marked TBD rather than left blank.
Silent material or construction substitutions are prohibited.
A useful FIBC bag RFQ connects the product, payload, equipment, handling environment, protection needs, compliance obligations, and delivery scope in one controlled document. Bag size and unit price are only part of that specification.
Buyers do not need to engineer every seam or select every material before contacting a supplier. They do need to distinguish fixed requirements from preferred features and areas where the supplier may propose a solution. This allows qualified FIBC manufacturers to optimize the construction while keeping safety, equipment compatibility, documentation, and commercial scope visible.
Jebic Packaging can review product properties, bulk density, fill weight, filling and discharge equipment, handling methods, compliance requirements, and logistics constraints before preparing a drawing and itemized quotation. Providing this information at the RFQ stage reduces repeated clarification, improves sample accuracy, and creates a clearer basis for approving the final bag specification.
Provide the product, physical form, bulk density, target and maximum fill weight, bag or pallet dimensions, filling and discharge equipment, lifting method, required protection, safety and compliance conditions, printing, packing, order quantity, destination, and required documents.
Not always. If an approved design must be reproduced, state its fabric requirements. Otherwise, the buyer can define the SWL, service category, application, dimensions, handling, and required performance, then ask the supplier to propose the fabric and construction with supporting test evidence.
Bulk density connects the required product weight to the volume the bag must provide. A low-density product may fill the available bag volume before reaching the target weight, while a dense product may reach the SWL before the bag appears full.
No. It may refer to a target fill weight, SWL, nominal description, or approximate capacity. The RFQ should state the target weight, maximum possible load, required SWL, bulk density, usable volume, and service category separately.
State the liner’s purpose, material, thickness, style, dimensions, attachment, top and bottom design, sealing, barrier requirements, electrostatic compatibility, food-contact status, and required behavior during filling and discharge.
Include the UN number, proper shipping name, hazard class, packing group, physical form, maximum quantity, required packing instruction and IBC code, transport modes, route, jurisdictions, special provisions, and required approval evidence.
Only after the electrostatic risk has been assessed. Provide information about the powder, minimum ignition energy where known, flammable atmosphere, solvents, filling and discharge process, earthing availability, liner, and hazardous-area classification. A qualified safety assessment should determine the required electrostatic approach.
Yes, when the RFQ permits it. The supplier should describe the alternative, explain its effect, provide supporting evidence, and price it separately. Safety-critical, regulatory, equipment-interface, or customer-controlled requirements should not be changed without written approval.
No. A sample can support the RFQ but should have a unique identifier and be accompanied by a drawing and written specification. “Same as sample” does not reliably control materials, dimensions, safety classification, tolerances, testing, or manufacturing changes.
State the selected Incoterms® rule, the edition, and the exact named port, terminal, warehouse, or other place. For example, “FCA supplier facility, Nanjing, China, Incoterms® 2020” is clearer than “FCA China.”
Request a completed compliance matrix, proposed specification, drawing, manufacturing site, deviations, alternatives, exclusions, supporting evidence, sample plan, packing details, MOQ, unit prices, one-time charges, lead time, validity, and delivery terms.
A repeat-order RFQ should reference the approved drawing, specification, artwork, sample, test evidence, and revision. It should also require the supplier to identify any material, process, manufacturing-site, or regulatory changes since the previous order.
