A practical checklist to verify Chinese suppliers, spot warning signs early and compare offers on more than price before you place your first order.
Choosing a supplier is the decision that shapes everything that comes after it: quality, lead times, costs and how problems get solved. A cheap quote from the wrong factory is the most expensive mistake in importing. This guide walks through how to evaluate suppliers in a structured way.
Start with a clear specification
You cannot compare suppliers if each one is quoting something different. Before you ask for prices, write down:
- Materials, dimensions, weight and tolerances.
- Functions and performance requirements.
- Packaging, labeling and any certification your market requires.
- Target quantity for the first order and expected volume after that.
Send the same specification to every supplier. It makes quotes comparable and shows suppliers you are a serious buyer.
Factory or trading company?
Both can be good partners, but you should know which one you are dealing with.
- Factories usually offer better prices on their core products and more control over customization.
- Trading companies can offer lower minimum quantities and wider ranges, but add a margin and reduce your visibility over production.
Ask directly, then check: the business license shows the registered scope, and a factory should be able to show its production lines on a live video call.
Verify the company
Before sending money, check the basics:
- Business license: company name, registration number, registered capital, date of establishment and business scope. The name on the license should match the name on the contract and the bank account.
- Export experience: ask which markets they already ship to and which documents they usually prepare.
- Certifications: request product test reports and, where relevant, management system certificates such as ISO 9001. Check that they are valid and issued for the right product.
- Production capacity: number of lines, monthly output for your product type and current lead times.
For larger orders, a physical factory audit gives you evidence instead of promises.
Evaluate quality before price
- Order samples from your shortlist and compare them side by side. Our guide on ordering samples from China explains how.
- Ask about their quality process: incoming material checks, in-line checks and final inspection.
- Agree on how defects are handled before production: replacement, credit note or refund.
Warning signs
- A price far below every other quote with no clear explanation.
- Pressure to pay quickly, or a bank account in a different name from the company.
- Refusal to show the factory, share documents or send samples.
- Vague answers about minimum quantities, lead times or materials.
- Lead times that look unrealistic for the complexity of the product.
None of these alone proves fraud, but each one deserves an explanation before you continue.
Compare offers on total cost
Unit price is only one line. Compare:
- Minimum order quantity and price breaks.
- Payment terms (deposit and balance).
- Incoterm used in the quote. Incoterms explained shows why an EXW and a FOB price are not comparable.
- Packaging, tooling and sample costs.
- Lead time and capacity for repeat orders.
Shortlist, then decide
Keep at least two or three serious candidates until samples and checks are done. It gives you a fallback and a reference for negotiation.
If you would rather not do this alone, Zyntral can search and verify suppliers for you through our End to End import service, or check a specific supplier through certification consulting.
