How to Choose a Bag Manufacturer in China: A 12-Point Checklist

Price is only one factor. Compare factories, trading companies and sourcing partners by their fit, verified responsibilities and written terms—not labels alone. These are due-diligence prompts, not guarantees of future performance.

1. Factory or trading company?

Ask which legal entity will contract and receive payment; compare its licence, invoice and beneficiary through a separately verified channel. Clarify where production takes place and which steps are subcontracted. A trading company may provide sourcing or export coordination. Choose based on your needs and verified responsibilities, not an address format alone.

2. Product focus

Ask for product examples and how the requested construction, dimensions and print method will be specified. A broad or narrow catalogue alone proves neither capability nor quality; request evidence that matches your product, such as non-woven bags, cotton and canvas bags, gift, garment or shoe bags.

3. Material knowledge

Write down material and weight, dimensions and tolerances, handle and attachment, colour, artwork, seams, labels, packaging and applicable tests. Ask how measurable requirements will be checked. For printing, agree on the proof or sample reference and colour/placement assessment. Keep acceptance-critical details out of informal chat alone.

4. Certifications and audits

Start with the destination, intended use and buyer requirement; no single certificate list fits every order. Check each document's holder, site, scope, covered material/process, issuer and validity, and verify it where possible. Supplier statements, facility audits and product test reports are different evidence. A logo alone does not prove order coverage.

5. Sampling before commitment

Agree whether you need a stock or pre-production sample, what it must confirm, and which changes remain possible. Compare it with the written specification and keep the approved reference. Separate preparation from courier transit: EcoBag lists working samples in 3–7 working days after specifications are confirmed. Put sample, shipping and refund terms in the quote.

6. Quality control process

Agree the inspection stage, method/sample size, acceptance criteria, timing, cost and third-party access before production. AQL is one possible framework, not a universal default. List any required photos or reports and due dates in writing; do not assume they are included unless quoted.

7. Transparent pricing structure

Compare like-for-like material, dimensions, print, packaging, quantities, inspection and payment terms, using an Incoterm with a named place. Ask what is excluded, including freight, insurance and import charges. EcoBag lists FOB Guangzhou as standard, CIF/DDP on request, and 1–2 colour silk-screen printing included for listed products; confirm the order-specific quote.

8. Realistic lead times

Separate sample preparation, approval, bulk production and transit. Ask what starts each period and which approvals are needed. EcoBag lists sample preparation at 3–7 working days after specification confirmation; bulk and transit timing should be confirmed for the product, quantity and route, not treated as a guaranteed generic date.

9. Communication quality

Use enquiries to test whether the supplier answers order-specific questions. Record open items, owners, deadlines and the channel for formal approvals. Response speed alone cannot predict performance; assess answer quality alongside documents and agreed controls.

10. Payment safety

Check schedule, currency, beneficiary and bank charges in the contract. EcoBag publishes bulk terms of T/T 30% deposit and 70% before shipment (or against B/L copy); confirm the order-specific term. Verify bank-account changes using a known contact channel, not just the payment message.

11. References and repeat clients

If references matter, ask whether they can be shared with customer permission and what they cover; they may not represent your product or order. If confidentiality prevents disclosure, use samples, visits, verified documents, contract terms and inspection planning instead. Do not publish customer details without authorization.

12. Problem resolution

Define discrepancy evidence, notice period, review process and any remedies in the contract; do not assume replacement, credit or rework is automatic. Keep the approved specification, sample reference, inspection criteria and shipment records so both parties can assess claims against the same requirements.

Red flags

• Contract, invoice and beneficiary names differ without a verifiable explanation.
• Specifications, production location, subcontracting or delivery terms remain unclear in writing.
• Payment-account changes cannot be verified using a known contact channel.
• Claimed documents lack a clear holder, scope, date or issuer.
• The quote omits exclusions or gives an Incoterm without a named place.

Green flags

• Gives consistent legal-entity and production-scope information.
• Turns requirements into a reviewable specification.
• Separates sample, freight, production and delivery estimates.
• Explains price inclusions, payment milestones and named Incoterm place.
• Confirms included documents, inspections and remedies in writing.
