Chinese Supplier Background Check: Who You Are Paying, From the Official Registers

A written report signed by a PRC lawyer before the deposit goes out: factory or trader, court and enforcement records, and what to change in the contract.

A supplier background check tells you, before the deposit goes out, whether the company on the quotation is a factory or a trading company, whether it carries unpaid judgments or frozen assets, and whether it has filed anything that overlaps with your brand. We read mainland China's official registers, not an English supplier profile, and deliver an eleven-section report within 3 business days for USD 890 per supplier, or USD 590 per supplier with a contract package or for two or more suppliers. If you have one hour and no budget, search the court enforcement register before you pay.

Start from what is about to happen

Your situationFixed feeWhat we do
You are about to pay a first depositUSD 890 per supplier; USD 590 with a contract package or for two or more suppliersThe full report, ending with a plain answer: pay now, pay after named conditions are met, or do not pay this company.
You suspect the “factory” is a trading companyUSD 890 per supplierSection four sets the evidence side by side and tells you which company has to sign the NNN and the contract, and how to bring the real factory in.
The supplier has asked you to pay a new accountUSD 890, with the new payee checked as one of the related companiesConfirm whether the payee is a registered company linked to your supplier and whether the change fits the contract. A personal account or an unrelated company is flagged as a reason to stop.

The fee is per supplier, fixed and confirmed in writing before we start. The report covers the company you would contract with and up to two related companies, such as an affiliated factory or the company named on the payment details. A report in both English and Chinese, or more related companies inside a large group, is quoted before we start.

What the report checks, and against which register

Every finding is checked against the official source it comes from. Commercial databases are useful for finding leads quickly, but they lag, merge records and add their own scores, so we use them only to know where to look.

The registers we read include the National Enterprise Credit Information Publicity System for registration, shareholders, annual reports and penalties; China Judgments Online and the court enforcement information system for lawsuits, judgment debtors and the dishonest debtor list; the national pollutant discharge permit platform and the certification authority's register for factory evidence and quality certificates; customs credit records; and the CNIPA trademark and patent databases.

The report follows the same eleven sections every time, so you can compare suppliers side by side. The sample report (PDF) shows all eleven filled in for a fictitious supplier.

What a public-record check cannot tell you

We say this in every report because buyers sometimes read a clean report as a guarantee. It is not one. Public records show what is on file on the search date. They do not show product quality, actual production capacity, the condition of the machines, or how the owner will behave when a batch fails. Disputes that have not reached court, cases not yet published and very recent changes may not appear.

No register in China shows who owns a bank account, so we cannot confirm that an account number belongs to your supplier. What we can confirm is whether the payee name is a registered company and how it is connected. Our article on a supplier that says it has a new bank account sets out the checks to run before you pay. An on-site audit of the factory is a different service, run by inspection companies, and the two work well together: we tell the auditor which company and address to verify.

Is my Chinese supplier a factory or a trading company?

Usually you can tell from the official registers within a day, but no single record settles it. Read four together: the business scope on the licence, the number of employees covered by social insurance in the annual report, the pollutant discharge register and the customs registration. A “factory” with 300 workers on its website and four insured employees deserves a direct question before you pay.

A trading company is not a reason to walk away. It is a reason to bring the factory into the NNN and the contract, as a party, a guarantor or at least a named manufacturer whose identity the trader cannot change without your consent. Our guide Is Your Chinese Supplier a Real Factory or a Trading Company? shows how to read each register yourself, and Your Chinese Supplier Is a Trading Company covers the contract.

Unpaid judgments matter more than the number of lawsuits

A supplier with twenty lawsuits is not necessarily a bad supplier. Many of those cases may be the supplier suing its own customers for unpaid invoices, which is ordinary business. What matters is whether other creditors who won judgments have been paid. The enforcement register shows companies that are judgment debtors, companies on the dishonest debtor list, and cases closed because the court could not find assets to seize. Any of these, in the last two or three years, changes our advice on how much to pay up front.

We also read the cases brought by other buyers: what the dispute was about, which court heard it and how it ended. Repeated quality or late-delivery claims are more telling than any rating. Our article Verify a Chinese Supplier's Court Records explains how to run the enforcement search yourself.

Can I check a Chinese supplier myself?

Yes, for a first screen, and we would encourage it before you spend money. You need the supplier's exact registered Chinese name or its unified social credit code, which should appear on the business licence the supplier sends you. With either, the National Enterprise Credit Information Publicity System shows the registration, shareholders and annual reports, and the court enforcement information system shows judgment debtors. Both are free and both are in Chinese.

Where a self-check usually stops is the reading. Matching an English trading name to the right Chinese company, following ownership into related companies, reading the annual report's insured headcount against the factory you visited, and deciding what a finding means for the deposit is where the time goes. That reading is what the report is for.

From the findings to the contract

A check is only worth paying for if it changes what you sign or how you pay. The report ends with recommended protections tied to each finding, written so your purchasing team can use them in the next email to the supplier.

Typical results are the supplier's exact Chinese name and registration code in the contract, a clause that payment goes only to the account in the contracting company's own name, the factory brought in as a party where the supplier is a trader, a smaller deposit or payment against an inspection report where enforcement records are poor, and an IP clause where the supplier has filed marks or designs resembling yours.

That is why the check is USD 590 per supplier when ordered with an NNN or contract package: the findings go straight into the documents we draft.

Fee, delivery and what is extra

The report is signed by a PRC-licensed lawyer and issued through the firm. Delivery time runs from receipt of your payment and the supplier's details, counted in mainland China business days.
