When buyers request quotations from several custom bag suppliers in China, the lowest unit price can appear to be the best offer.
In practice, two quotations may describe very different products even when the product names and reference images look similar.
Differences may exist in:
A quotation should therefore be evaluated as a complete specification and commercial offer—not as a single price per piece.
The first step is to make sure every supplier is quoting the same product.
A price comparison is only meaningful when the technical specifications are aligned.
Before comparing quotations, confirm the following information for every supplier:
| Specification | What Buyers Should Confirm |
|---|---|
| Product type | Tote bag, cosmetic bag, backpack, cooler bag or another structure |
| Finished size | Width × height × gusset |
| Material | Cotton, canvas, RPET, polyester, jute, felt or non-woven |
| Fabric weight | GSM, oz or denier where applicable |
| Lining | Material, thickness and color |
| Handles | Material, width, length and attachment |
| Closure | Zipper, snap, drawstring, hook-and-loop or open top |
| Reinforcement | Bottom board, foam, webbing or internal patches |
| Logo | Method, size, colors and print position |
| Packaging | Bulk packing, individual bag, sleeve, box or hangtag |
| Quantity | Total quantity and quantity per color or design |
A supplier quoting 280 GSM canvas cannot be compared directly with another supplier quoting 340 GSM canvas.
Likewise, a basic polyester zipper is not equivalent to a higher-grade zipper with stronger tape, slider and puller.
Reference images are useful, but they do not define every construction detail.
A supplier may interpret the same image differently regarding:
Buyers should ask each supplier to list what is included in the quotation.
A clear quotation should not state only:
Custom canvas tote bag, US$2.20 per piece.
It should state something closer to:
Cotton canvas tote, 38 × 32 × 10 cm, 12 oz fabric, cotton webbing handles, one internal pocket, zipper closure, one-color screen print and individual polybag.
The more complete quotation is easier to compare and less likely to create disputes after sampling.
Material names are often too broad.
For example, “canvas” may refer to:
Similarly, “RPET fabric” does not explain:
Buyers should confirm:
A lower-priced quotation may use a lighter fabric, lower recycled content or a different coating.
Small dimensional differences can affect both material cost and shipping volume.
For example, these bags may appear similar but use different amounts of fabric:
The larger bag may also require:
Buyers should compare:
A quotation should clearly state whether the size is measured flat, externally or internally.
Handle and seam construction can create major price and performance differences.
Important comparison points include:
A bag with stronger webbing handles and reinforced stitching may cost more but provide better repeated-use performance.
The buyer should compare the finished construction rather than assuming that the same fabric means the same carrying strength.
Different logo methods create different costs and results.
Common options include:
A quotation should specify:
A one-color screen print should not be compared directly with a full-color heat-transfer print.
Buyers should also confirm whether the quotation includes:
Some suppliers include setup costs in the unit price, while others list them separately.
A supplier may quote different prices for:
The price difference may come from:
Buyers should confirm whether MOQ applies:
A quotation for 2,000 pieces in one color may not remain valid if the order is divided into four colors.
When comparing suppliers, use the same quantity and color breakdown.
Sample pricing is usually higher than bulk unit pricing.
Sample costs may include:
Buyers should compare:
A low sample fee is not necessarily an advantage if the sample uses substitute materials or simplified construction.
The approved sample should become the production reference.
Packaging can significantly affect the quotation.
Common options include:
Buyers should confirm:
A lower-priced quotation may use bulk packing, while another supplier includes individual retail packaging.
These quotations are not directly comparable.
The price must include a clear trade term.
Common terms include:
The buyer collects the goods from the supplier’s factory or warehouse.
The buyer normally handles:
The supplier normally delivers the goods to the agreed port and completes export customs clearance.
The buyer handles the main international freight and destination costs.
The supplier includes sea freight and insurance to the named destination port.
The buyer still needs to confirm destination charges, customs and local delivery.
The quotation may include transport, import clearance, duties and final delivery, depending on the exact arrangement.
Buyers should confirm what is included rather than relying only on the term.
An EXW price will usually appear lower than an FOB or DDP price.
Quotation comparisons should use the same trade term and destination.
The lowest factory price may not produce the lowest final cost.
A practical comparison should include:
The relevant calculation is:
Total Landed Cost ÷ Usable Quantity
Defective, damaged or incorrect products reduce the usable quantity and increase the actual cost per bag.
For high-volume or bulky products, carton dimensions may affect the final cost as much as the unit price.
Lead time should be divided into separate stages:
A quotation stating “30 days” may mean:
Buyers should confirm the starting point and whether the lead time includes packaging.
Custom-dyed fabrics, special zippers and printed packaging may extend the schedule.
A lower price may reflect fewer inspection steps.
Buyers should ask:
Important quality points may include:
The inspection criteria should be agreed before production.
Common payment structures may include:
Buyers should compare:
A low quotation combined with unfavorable payment terms may create greater financial risk.
Payment arrangements should match the order size, supplier relationship and inspection plan.
A professional quotation should identify exclusions.
Common excluded costs include:
Buyers should request a written list of included and excluded items.
This prevents additional charges from appearing after the order is approved.

A comparison table makes specification differences visible before supplier selection.
The unit price does not show material, packaging, trade terms or quality risk.
Suppliers may quote different GSM, dimensions, zippers or printing methods.
A total quantity may not satisfy the minimum for each color or design.
Bulky bags can create high freight and storage costs.
Terms such as “canvas,” “RPET” or “premium polyester” require further specification.
Digital images cannot confirm hand feel, thickness, construction or printing quality.
Testing, tooling, packaging and freight may be excluded.
The lowest initial quotation may create higher defect, delay or communication risk.
Before selecting a quotation, ask:
Hangzhou INITI Imp&Exp Co., Ltd. has 16 years of experience in custom bag and packaging development, supported by two production facilities and management or compliance systems including SEDEX, DISNEY, GRS, HIGG and ISO9001.
Our quotation process can include:
For buyers comparing several product options, INITI can provide a standard specification together with alternative material, structure or packaging options where appropriate.
This helps buyers understand which changes affect price, MOQ, performance and lead time.
The suppliers may be quoting different materials, fabric weights, dimensions, accessories, printing methods, packaging or trade terms.
No. Buyers should compare the complete specification, total landed cost, sample quality, production control and supplier reliability.
Send the same specification sheet, quantity, artwork, packaging requirement and trade term to every supplier.
Neither is automatically better, but all quotations should use the same term. FOB often makes export-cost comparison easier for international buyers managing their own freight.
Approve the material, dimensions, construction, logo, color, packaging, sample, quality standard, lead time, payment terms and trade term in writing.
Custom bag quotations from China should be compared line by line, not price by price.
A reliable comparison requires alignment of:
The best quotation is not necessarily the cheapest. It is the offer that provides the required product, clear commercial conditions and acceptable total landed cost with controlled production risk.
To receive an accurate quotation, please provide:
If you have not finalized all details, you can first send your intended use and target quantity, and we can recommend a suitable specification.
