Introduction
One of the most common questions buyers send to a bag manufacturer is:
“How much is this bag?”
Unfortunately, a photo or product name alone is usually not enough to calculate an accurate price.
Two bags that look almost identical can have very different manufacturing costs because of differences in:
- Fabric
- Size
- Material weight
- Lining
- Zippers
- Handles
- Printing
- Internal structure
- Order quantity
- Packaging
For example, a simple tote bag could be made from lightweight cotton, 12 oz canvas, recycled polyester or laminated non-woven material. Each option creates a different material cost and production process.
The same applies to backpacks, cooler bags, cosmetic bags, crossbody bags and travel bags.
For B2B buyers, providing a clear RFQ — Request for Quotation — helps the manufacturer calculate a more realistic price and reduces repeated emails during product development.
You do not need to know every technical detail before contacting a supplier.
However, several pieces of information make a major difference.
The Minimum Information Needed for a Bag Quote
For an initial quotation, try to provide at least:
| Information | Example |
|---|---|
| Bag type | Canvas tote bag |
| Estimated quantity | 3,000 pcs |
| Size | 40 × 35 × 12 cm |
| Material | 12 oz cotton canvas |
| Color | Natural |
| Logo | 1-color screen print |
| Main features | Long handles + inner pocket |
| Packaging | Individual polybag |
| Destination | Germany |
If some specifications are not finalized, tell the manufacturer the intended use and target quantity.
A supplier can often recommend a suitable material or construction based on the application.
1. Bag Type or Reference Product
The first step is identifying what type of bag you need.
Examples include:
- Tote bag
- Shopping bag
- Backpack
- Crossbody bag
- Drawstring bag
- Cooler bag
- Cosmetic bag
- Travel bag
- Laundry bag
- Wine bag
- Storage bag
If you already have a product in mind, send:
- Reference photos
- Product drawings
- Existing sample
- Product link
- Sketch
A reference image is often much more useful than a long written description.
However, images alone are not enough for a final quotation because they do not show exact:
- Dimensions
- Fabric specifications
- Internal structure
- Material thickness
The manufacturer may still need additional information.
2. Bag Dimensions
Size directly affects material consumption.
For most bags, provide dimensions in the format:
Width × Height × Depth
For example:
40 × 35 × 12 cm
For a flat tote without a gusset:
38 × 42 cm
For more complicated bags, provide dimensions for:
- Main body
- Side gusset
- Bottom gusset
- Handles
- Shoulder straps
- Pockets
Even a small size change can affect cost when the order quantity is large.
A bag that increases from 35 cm to 40 cm in width may require additional fabric across thousands of units.
What If You Do Not Know the Correct Size?
Tell the supplier what the bag needs to carry.
For example:
“The bag needs to hold a 15.6-inch laptop, charger and notebook.”
or:
“The tote should carry approximately six grocery items and two bottles.”
This allows the manufacturer to recommend dimensions based on actual use.
For functional bags, this is often more useful than selecting an arbitrary size.
3. Estimated Order Quantity
Quantity is one of the most important pricing factors.
A quotation for:
- 500 pcs
- 2,000 pcs
- 10,000 pcs
- 50,000 pcs
can be significantly different.
Higher quantities may reduce unit cost because fixed production costs can be distributed across more units.
These costs may include:
- Printing screens
- Cutting setup
- Mold or tooling
- Sampling
- Machine setup
- Packaging preparation
When requesting a quotation, provide a realistic estimated quantity.
For example:
Please quote 1,000 / 3,000 / 5,000 pcs.
This allows buyers to compare price levels at different order volumes.
4. Material Type
Material can represent a large part of the finished bag cost.
Common bag materials include:
- Cotton
- Canvas
- Jute
- Polyester
- Nylon
- RPET
- Non-woven PP
- Felt
- Tyvek
- PU
- PVC
- TPU
Simply writing:
“Cotton bag”
may still not be enough.
Cotton fabric can vary significantly by:
- Fabric weight
- Yarn
- Weave
- Treatment
- Certification
The same applies to polyester and nylon.
5. Fabric Weight or Specification
When possible, provide the fabric specification.
Cotton and Canvas
Common specifications may be described as:
- 6 oz
- 8 oz
- 10 oz
- 12 oz
- 16 oz
or by GSM.
Higher-weight canvas generally uses more material and therefore costs more.
Polyester and Nylon
Common specifications include:
- 210D
- 300D
- 420D
- 600D
- 900D
The denier number alone does not determine quality, but it gives the manufacturer an important starting point.
Non-Woven Material
Usually specified by GSM, such as:
- 80 GSM
- 100 GSM
- 120 GSM
What If You Do Not Know the Fabric Specification?
You can provide:
- Reference sample
- Close-up fabric photo
- Target use
- Target price level
For example:
“We need a durable grocery tote for repeated supermarket use.”
The supplier may recommend a medium or heavyweight canvas instead of requiring you to specify the exact weight yourself.
6. Material Composition and Sustainability Requirements
If recycled or certified materials are required, mention this at the quotation stage.
Examples include:
- RPET polyester
- Recycled cotton
- Organic cotton
- GRS-certified material
- RCS requirements
Do not wait until bulk production to ask whether the material can be certified.
Certification requirements can affect:
- Material supplier selection
- Material price
- Minimum quantity
- Documentation
- Production process
For example:
Main fabric: 100% recycled polyester
GRS documentation required.
is much clearer than:
“Need eco-friendly fabric.”
7. Bag Color
Color also affects quotation accuracy.
Tell the manufacturer whether you need:
- Natural fabric
- Stock color
- Custom Pantone color
- Printed pattern
Natural cotton may require no dyeing.
A custom Pantone fabric may require:
- Dyeing
- Minimum fabric quantity
- Additional lead time
For polyester bags, custom colors may also require minimum material quantities.
If exact color matching matters, provide:
Pantone 186 C
rather than simply:
Red.
8. Logo Artwork and Decoration Method
Custom branding can significantly affect cost.
Common decoration methods include:
- Screen printing
- Heat transfer
- Digital printing
- Sublimation
- Embroidery
- Woven label
- Rubber patch
- PU patch
- Foil printing
Provide the logo artwork whenever possible.
Preferred formats include:
- AI
- EPS
- SVG
Vector artwork allows the manufacturer to evaluate:
- Number of colors
- Print dimensions
- Artwork complexity
Number of Print Colors Matters
For screen printing, a one-color logo usually costs less than a four-color design.
For example:
Option A
White logo, one side, 15 × 10 cm
Option B
Five-color artwork, both sides, 30 × 25 cm
These are very different production requirements.
Therefore, tell the supplier:
- Number of colors
- Print position
- Print size
- One side or two sides
9. Handle or Shoulder Strap Specifications
Handles are easy to overlook but can noticeably change cost.
Provide information such as:
- Short hand handles
- Long shoulder handles
- Cotton webbing
- Polyester webbing
- Self-fabric handles
- Adjustable strap
- Detachable strap
If you know the dimensions, include:
Handle: 2.5 × 60 cm cotton webbing.
For crossbody and travel bags, specify whether you need:
- Adjustable buckle
- Detachable hooks
- Shoulder pad
10. Zipper and Closure Requirements
Different closures create different costs and structures.
Common options include:
- Open top
- Drawstring
- Snap button
- Magnetic button
- Velcro
- Zipper
- Roll-top closure
For zipper bags, the manufacturer may also need to know:
- Nylon coil zipper
- Metal zipper
- Waterproof zipper
- Double zipper
- Zipper brand requirement
For premium or technical projects, zipper quality can have a meaningful effect on the final price.
11. Internal Structure and Pockets
This is especially important for:
A photo of the exterior may not show the internal construction.
Provide details such as:
- Main compartment
- Laptop sleeve
- Zipper pocket
- Mesh pocket
- Bottle pocket
- Shoe compartment
- Wet compartment
- Internal divider
Each additional component requires:
- More material
- More cutting
- More sewing
- Additional accessories
A simple backpack and a multi-compartment backpack may use similar outer fabric but have very different production costs.
12. Lining Requirements
Some bags are unlined.
Others may use:
- 190T polyester
- 210D polyester
- RPET lining
- PEVA
- Aluminum foil
- TPU
- Cotton lining
Lining is especially important for:
For cooler bags, also provide:
- Insulation type
- Foam thickness
- Inner lining material
because these components strongly affect cost.
13. Reinforcement and Padding
Functional bags may need additional reinforcement.
Examples include:
- Laptop padding
- Shoulder strap foam
- Reinforced bottom
- EVA panels
- PE board
- Foam backing
Tell the manufacturer what the bag is expected to carry.
For example:
Backpack should carry a 15.6-inch laptop and approximately 8 kg total load.
This helps determine whether additional reinforcement is needed.
14. Hardware Requirements
Hardware can have a surprising impact on cost.
Examples include:
- Plastic buckles
- Metal buckles
- D-rings
- Snap hooks
- Eyelets
- Rivets
- Magnetic buttons
Premium metal hardware usually costs considerably more than standard plastic components.
If specific hardware is important, include:
- Material
- Finish
- Color
Examples:
Matte black metal hardware
or:
Standard black plastic buckles.
15. Packaging Requirements
Packaging should be included in the quotation.
Common options include:
- Bulk packing
- Individual polybag
- Recycled polybag
- Paper sleeve
- Hangtag
- Barcode sticker
- Retail box
Retail packaging can add meaningful cost.
If the bag needs:
- Amazon FBA labels
- Retail barcodes
- Country-specific labeling
- Custom cartons
tell the supplier before confirming the price.
16. Carton Requirements
Large retailers may specify:
- Maximum carton weight
- Carton dimensions
- Number of pieces per carton
- Shipping marks
These requirements can affect:
- Packing efficiency
- Carton cost
- Freight
For large international orders, carton specifications should be discussed before bulk production.
17. Compliance and Testing Requirements
Some projects require additional product testing.
Examples may include:
- REACH
- CPSIA
- Prop 65
- Food-contact testing
- Colorfastness
- Load testing
- Fabric composition testing
Requirements vary by:
- Product
- Market
- Buyer
Testing costs should therefore be included in the RFQ when known.
Retailers may also require factory audits or certifications.
Mention these requirements early.
18. Target Market
Tell the manufacturer where the product will be sold.
For example:
- United States
- European Union
- United Kingdom
- Australia
- Japan
Different markets may have different:
- Compliance requirements
- Labeling
- Packaging
- Testing expectations
The destination market may therefore affect product development.
19. Delivery Destination
For an accurate landed-cost comparison, provide the shipping destination.
Useful information includes:
- Country
- City
- Port
- Postal code
For example:
Hamburg, Germany
or:
Los Angeles, CA 90021, USA
This allows the supplier or freight forwarder to estimate logistics if required.
20. Required Delivery Date
Lead time matters.
Tell the manufacturer whether the bags are needed for:
- Exhibition
- Product launch
- Holiday campaign
- Retail promotion
- Corporate event
For example:
Goods must arrive in Germany before October 15.
This is much more useful than:
“Urgent.”
A tight delivery schedule may require:
- Stock fabric
- Faster printing
- Air freight
which can change the quotation.
21. Sample Requirements
Tell the manufacturer what type of sample you need.
Common options include:
Existing Sample
A similar product already produced by the factory.
Usually faster and less expensive.
Custom Prototype
Made according to your specifications.
May require:
- Fabric sourcing
- Custom printing
- Custom hardware
Pre-Production Sample
Produced after order confirmation using materials close to the final production specification.
Sample requirements can affect both:
- Development time
- Cost
What If You Only Have a Photo?
That is common.
You can send the photo with:
- Estimated quantity
- Intended use
- Approximate size
- Preferred material
- Target market
For example:
We need a bag similar to the attached photo for a supermarket project.
Size approximately 40 × 35 × 12 cm.
Quantity: 5,000 pcs.
We prefer cotton canvas with a one-color logo.
The manufacturer can then identify missing specifications.
What If You Have Not Finalized the Product?
You do not need to finalize every detail before sending an inquiry.
A useful initial request can include:
- Product type
- Intended use
- Target quantity
- Reference image
- Target price level
For example:
We need a reusable shopping bag for a grocery chain. Estimated quantity is 10,000 pcs. The bag should carry approximately 8–10 kg and be suitable for repeated use. We have not finalized the fabric weight yet.
This gives the supplier enough context to recommend:
- Material
- Fabric weight
- Handle structure
- Reinforcement
This is often more effective than guessing technical specifications.
Information That Has the Biggest Impact on Price
Not every specification affects cost equally.
The most important usually include:
1. Quantity
Higher volumes generally reduce unit cost.
2. Material
Fabric type and weight often represent a major proportion of total cost.
3. Bag Size
Larger bags require more material.
4. Construction Complexity
More pockets, lining and compartments mean more sewing time.
5. Printing
Artwork size, color count and printing process affect cost.
6. Hardware
Premium zippers and metal accessories can significantly increase pricing.
7. Packaging
Retail packaging costs more than simple bulk packing.
Why Quotations from Different Suppliers Can Be Very Different
If the RFQ is incomplete, each supplier may make different assumptions.
For example, you ask:
“Please quote 5,000 canvas tote bags.”
Supplier A may calculate:
- 8 oz canvas
- No lining
- Basic handles
Supplier B may calculate:
- 12 oz canvas
- Reinforced handles
- Inner pocket
Supplier C may calculate:
- 16 oz canvas
- Premium printing
- Individual packaging
The quotations are not actually for the same product.
This is one reason buyers sometimes receive very different prices from different manufacturers.
A detailed specification makes quotations much easier to compare.
Create a Standard Bag RFQ Sheet
For buyers sourcing bags regularly, it is useful to create a standard RFQ template.
Include:
Product
- Bag name
- Reference photo
Material
- Main fabric
- Fabric weight
- Lining
Dimensions
- Width
- Height
- Depth
Construction
- Handles
- Pockets
- Zippers
- Compartments
Branding
- Logo
- Print process
- Artwork size
Order
- Quantity
- Sample requirements
- Packaging
- Delivery date
- Destination
This reduces sourcing time and prevents important details from being forgotten.
Example: Simple Cotton Tote Bag RFQ
Product: Cotton Tote Bag
Quantity: 5,000 pcs
Size: 38 × 42 cm
Material: 10 oz cotton canvas
Color: Natural
Handle: 2.5 × 65 cm self-fabric handles
Printing: 1-color screen print, one side
Logo Size: 20 × 15 cm
Packaging: 50 pcs per polybag, bulk packed
Destination: Rotterdam, Netherlands
Required Delivery: November
This information is usually enough for a reasonably accurate initial quotation.
Example: Backpack RFQ
Product: Laptop Backpack
Quantity: 3,000 pcs
Size: 45 × 30 × 15 cm
Outer Material: 600D polyester with PU coating
Lining: 210D polyester
Laptop Compartment: Fits 15.6-inch laptop
Pockets: Front zipper pocket + two side bottle pockets
Straps: Padded adjustable shoulder straps
Logo: Embroidery
Color: Black
Packaging: Individual polybag
Target Market: Germany
Compared with simply requesting a “600D backpack,” this specification gives the manufacturer a much clearer basis for costing.
Example: Cooler Bag RFQ
Product: Insulated Grocery Cooler Bag
Quantity: 10,000 pcs
Size: 40 × 32 × 20 cm
Outer Material: 300D RPET polyester
Insulation: 5 mm PE foam
Inner Lining: PEVA
Closure: Double zipper
Handles: Reinforced polyester webbing
Logo: 2-color screen printing
Packaging: Bulk packing
Certification: GRS material required
For insulated bags, insulation and lining should always be included because they strongly affect the cost.
Common RFQ Mistakes
1. Sending Only a Product Photo
Photos help explain appearance but rarely show all specifications.
2. Asking for the “Best Price” Without Quantity
Manufacturers cannot calculate a meaningful production price without knowing volume.
3. Not Specifying Material Weight
“Canvas” or “polyester” covers many different specifications.
4. Changing Specifications After Quotation
If material, size or construction changes, the price will usually change too.
5. Comparing Different Specifications
A low quotation may simply be based on:
- Lighter fabric
- Cheaper zipper
- Less reinforcement
Compare specifications before comparing prices.
A Practical Checklist Before Sending Your Inquiry
Before sending an RFQ, prepare as much of the following as possible:
- Bag type or reference image
- Estimated quantity
- Bag dimensions
- Main fabric
- Fabric weight or denier
- Color
- Logo artwork
- Printing method
- Handle or strap specification
- Zipper or closure
- Internal pockets
- Lining
- Padding
- Hardware
- Packaging
- Certification requirements
- Target market
- Delivery destination
- Required delivery date
- Sample requirements
You do not need every item for the first inquiry.
But the more critical information you provide, the more accurate the quotation will be.
Requesting a Custom Bag Quote from INITI
For an initial custom bag quotation, buyers can provide:
- Logo artwork
- Estimated quantity
- Preferred size or reference dimensions
- Required colors
- Packaging requirements
If you already know the material, structure, printing process or certification requirements, include those as well.
If you have not finalized all details, you can first send your intended use and target quantity, and a suitable specification can be recommended based on the project.
This is often the fastest way to move from an initial concept to a realistic production quotation.
FAQ
Can a bag manufacturer quote from a photo?
Yes, an approximate quotation may be possible, but additional information such as dimensions, material and quantity is usually required for accurate pricing.
What information affects bag price the most?
Material, bag size, quantity, construction, printing, accessories and packaging are usually the biggest factors.
Do I need technical drawings before requesting a quote?
No. Reference photos, dimensions and a description of the intended use are often enough for the initial stage.
Should I provide my target price?
It can be helpful. A target price allows the manufacturer to recommend materials or structures that fit the budget.
Can I request several quantity levels?
Yes. Asking for prices at 1,000, 3,000 and 5,000 pieces can help you understand how quantity affects unit cost.
Do certification requirements affect price?
They can. Certified materials and order-level documentation may require different suppliers, minimum quantities and processes.
Why does the price change after sampling?
The sample may reveal changes in material consumption, structure, hardware or production complexity that were not visible during the initial quotation.
What if I do not know which material to use?
Send the intended application, expected quantity and reference images. The manufacturer can recommend suitable material options.
Conclusion
An accurate custom bag quotation begins with a clear product specification.
For most projects, the most important information is:
product type + quantity + size + material + construction + logo + packaging
Additional details such as certification, testing and delivery requirements can make the quotation even more precise.
Buyers do not need to be bag manufacturing experts before contacting a supplier.
If the technical specification is not finalized, providing the intended use, target quantity and reference product gives the manufacturer enough context to recommend suitable options.
The main goal is to make sure every supplier is quoting the same product specification.
That makes it much easier to compare:
- Price
- Material
- Production capability
- Quality
- Lead time
and prevents a low quotation from appearing attractive simply because important specifications were omitted.
