A low quotation is not the same as a low-risk order.

Before you place a purchase order with a Chinese supplier, you need clear answers about the product, the company behind the quotation, the evidence required before payment and the point at which the goods will be accepted.

This checklist is designed for overseas B2B buyers sourcing finished goods, components or custom products from China. It is a procurement-control tool, not legal, customs or product-compliance advice.

1. What exactly are you buying?

Start with a specification that two different suppliers can read in the same way. A product name and reference photo are rarely enough.

Record, where relevant:

  • model or drawing revision;
  • dimensions and tolerances;
  • material, grade, thickness, finish and color;
  • components and accessories included;
  • critical performance requirements;
  • logo, artwork, labeling and packaging;
  • quantity, acceptable overrun or underrun and spare parts;
  • destination market and intended use.

Mark the requirements that are critical to function, safety or salability. If a supplier proposes a substitution, require written approval before production.

2. Which market requirements apply to the exact product?

Avoid the broad question, “Is it certified?” Instead ask:

  • Which rule, standard or buyer requirement applies in the destination market?
  • Who is responsible for conformity assessment, labeling, technical files and importer obligations?
  • Which exact model, material and variant does the evidence cover?
  • Who issued the report or certificate, and how can its status and scope be checked?

Testing, inspection and certification are different activities. ISO explains that conformity assessment can include testing, inspection and certification, while ISO itself does not certify companies or products. A genuine document for a different model is not evidence for the item in your cartons.

If the product is regulated or safety-critical, confirm the requirements with the relevant authority or a qualified specialist before ordering.

3. Which legal entity will take the order and receive the money?

Record the registered Chinese legal name, unified social credit code, registered address and authorized contact. If the supplier uses an English business name, record it separately and ask how it relates to the registered Chinese entity.

Compare the names shown on the business license, quotation, contract, bank beneficiary, relevant reports and shipping documents. A different name is not automatically fraud: a manufacturer may use a related trading or export company. But the relationship and each party's responsibility should be explained and documented before payment.

China's National Enterprise Credit Information Publicity System provides official enterprise registration and regulatory information. Treat it as one input, not a complete guarantee of capability or financial health.

Search with the exact registered Chinese name or unified social credit code. The official system may use a Chinese interface and require authentication or a CAPTCHA. Inability to access it is not, by itself, a supplier red flag.

4. Are you dealing with a manufacturer, a trading company or both?

None of these structures is automatically good or bad. Identify who owns the production site, which processes are subcontracted, who controls changes and who is responsible for rework. A live walkthrough or scoped factory visit can test whether order-critical capabilities are observable at the stated site.

Read our comparison of supplier verification, factory visits, product inspection and laboratory testing before choosing a check.

5. What evidence shows the supplier can make this product?

A polished profile shows marketing ability, not capability for your exact order. Ask for current, product-specific evidence: a dated walkthrough, the critical equipment and process, relevant quality records, outsourced stages and a realistic lead-time calculation. Look for several pieces of evidence that tell the same story.

For a category-specific example, see how to screen a Chinese motorcycle helmet supplier.

6. Has the approved sample been defined and retained?

A sample is useful only when everyone knows what it represents. Record the sample date, model, specification revision, materials, color, markings, packaging and any approved exceptions. Keep one reference sample or a complete signed photo record. If laboratory testing was performed, record exactly which sample and configuration were tested.

State in the purchase order that changes to material, component source, tooling, process, coating, artwork or packaging require written approval. For a custom product, consider a first-article check before full production. A good pre-production sample reduces ambiguity; it does not guarantee that every production unit will match it.

7. Are all quotations based on the same scope?

Before ranking suppliers by price, normalize the specification, quantity, included components, testing, tooling, packaging, delivery term, payment, lead time and remedy. Write the Incoterms® rule, named place and edition—for example, FCA [named place], Incoterms® 2020. A quotation that says only “FOB China” leaves important details unclear.

Use the detailed guide to compare China supplier quotes on the same scope.

8. What is included in the price—and what is excluded?

Separate unit price from one-time and excluded costs such as tooling, samples, testing, packaging, inland handling, freight, duty, tax and destination charges. The lowest unit price is not automatically the lowest landed cost. Use current official import information and qualified customs or logistics advice where needed.

9. Is the lead time tied to clear starting conditions?

“30 days” can mean 30 days after deposit, artwork approval, sample approval or material arrival. Put the timeline in calendar terms: specification and sample approval, material readiness, production, inspection and shipment release. Ask what starts the clock and which materials or subcontractors sit on the critical path. Leave room for rework and reinspection.

10. Does the payment plan match the evidence you will receive?

There is no universal payment formula that proves a supplier is safe. Tie each milestone to specified evidence and choose a payment method appropriate to the order and relationship. Trade-finance methods distribute risk differently; none replaces product quality control.

Verify any bank-detail change through a second, previously established channel—never through a new phone number or contact supplied in the same change request.

11. What will be inspected, when and against which criteria?

Before production, agree on the inspection stage, reference specification and sample, sampling approach, defect definitions, checks, evidence and shipment-release authority. An inspection reports what was observed in the units and characteristics examined at a point in time. When sampling is used, its conclusions are limited by the agreed sampling plan and decision rule.

The supplier-check comparison explains what product inspection can and cannot prove.

12. What happens if the goods or documents do not match?

Resolve the difficult questions while both parties still want the order. Your purchase order or contract should address written change approval, nonconforming goods, rework and reinspection, shortages, late delivery, replacement parts, tooling ownership and the dispute process. Obtain professional advice where appropriate.

The goal is not to write the longest contract. It is to remove the assumptions most likely to become expensive later.

A practical go/no-go gate before the PO

Pause the order if a critical question remains unanswered—especially product scope, legal counterparty, bank beneficiary, applicable market requirements, approved sample, inspection criteria or change control.

An unanswered question is not always a reason to reject a supplier. It is a reason to define the risk and decide whether an additional safeguard, independent check or different supplier is needed.

What to send Taotao Sourcing

If you want a second pair of eyes before placing an order, send the product link, drawing or specification, estimated quantity, target market, supplier's legal name and quotation, required delivery date and the questions you have not been able to verify.

Privacy first: For initial contact, do not send full bank details, personal data, customer names, unreleased drawings or unredacted quotations through WhatsApp. Redact sensitive fields and review our privacy note before sharing complete confidential files.

Subject to availability and a written scope, Taotao Sourcing can support supplier verification, a South China factory visit, an agreed product inspection or managed sourcing. The scope should state what will be checked, what evidence you will receive and what remains outside the assignment.
