China supplier evaluation: the eight-step method

Published · Method reviewed and updated

The failures that cost buyers money on China-sourced equipment are rarely a bad choice from a sound shortlist. They start earlier, when the shortlist was built from quotations alone and nobody checked that the companies on it could finish the work. For commodity goods the cost of a wrong supplier is a late shipment. For industrial equipment it is a project blocked at commissioning, a transformer that fails its routine tests at the factory, or a pressure vessel whose documents do not satisfy the lender. The method below is the one Sinospect runs and reports against; the same eight steps work for a buyer running the file in-house.

The eight steps at a glance

Each step is recorded in the qualification file; a failed step stops the file until it is cleared.
StepWhat is checkedWhereWhen
1. RequirementSpecification, standards, destination documents, acceptance criteria, quantities and delivery point, written before the first supplier contactThe buyer’s own fileBefore any enquiry
2. Registry identityBusiness licence, 18-character Unified Social Credit Code, legal representative, registered capital, business scope, shareholders, abnormal-operation and penalty entries; sanctions screening on the entity and its legal representativeGSXT, the national enterprise credit registry; the sanctions lists that apply to the buyer’s marketDesk, day one
3. Public risk recordsCourt judgments, enforcement and dishonest-debtor listings, administrative penalties, the tax credit rating where published, customs registration where an export record is claimedChina Judgements Online, the enforcement platform, Credit China, the tax and customs registersDesk, day one
4. Payment pathBeneficiary name on the bank details against the licence; any Hong Kong invoicing company against its own register; the name on the VAT invoice; any later change of bank detailsCompany records, the quotation and the proformaDesk, before any deposit
5. Manufacturer or trading companyBusiness scope wording; registered against operating address; VAT invoice; catalogue breadth; minimum order quantity; location in the product’s manufacturing cluster; the name on audit reportsLicence, invoices, catalogue and audit reports, then the siteDesk, confirmed on site
6. Capacity and capabilityProduction lines, equipment in service, workforce, which steps are subcontracted and to whom, output against the claimed capacityLive video walk-through, then an on-site audit where the order warrants itSite, scheduled
7. Certificates, test reports and samplesEach certificate at its issuer’s register, notified bodies in NANDO, accredited certificates in IAF CertSearch, laboratories against their accredited scope; full test reports, not cover pages; the approved sample kept as the production reference; the quotation read line by line against the specificationIssuing bodies and the buyer’s fileDesk

1. Fix the requirement before the first contact

An evaluation without a written requirement measures the supplier against its own brochure. Before any enquiry goes out, the file holds the specification, the standards the equipment must meet, the documents the destination market and any lender will ask for, the acceptance criteria, the quantities and the delivery point. Every later step is read against that page, and it is also what makes two suppliers comparable.

A bill of quantities or a technical schedule goes into the file as drafted; a draft is enough to define what qualified has to mean for this order. Supplier answers on scope questions are kept in a technical clarification log from the first exchange, so that nothing agreed in a chat thread is lost by the time the order is written.

Every mainland Chinese company holds one legal identity document, the business licence (营业执照), issued under the State Administration for Market Regulation. It carries an 18-character Unified Social Credit Code. That code, or the registered Chinese name, is looked up in the National Enterprise Credit Information Publicity System, known as GSXT from its web address and sometimes as NECIPS. The record shows the legal representative, the registered capital, the registered business scope, the shareholders, the date of incorporation, and any abnormal-operation or administrative-penalty entries. The entity and its legal representative are also screened against the sanctions and restricted-party lists that apply to the buyer’s market; a listing is the one finding that is not a hold but a disqualification, and no later step reopens it.

The check is a match, not a glance: the name on the licence must be the name on the quotation, the code must resolve, the business scope must cover the equipment on order, and the incorporation date must fit the history the supplier describes. The record is in Chinese, and matching it to an English trading name is where most self-checks go wrong.

3. Read the public risk records

The registry says that a company exists. Three further public sources say how it behaves. China Judgements Online (中国裁判文书网) publishes court decisions, searched under the company and its legal representative. The enforcement platform (中国执行信息公开网) lists judgment debtors and the dishonest-debtor roll, which is where a company that has failed to perform a court-ordered payment, to a supplier or to its own workforce, appears. Credit China (信用中国) consolidates administrative penalties and the abnormal-operation list across agencies. Publication on China Judgements Online has been selective since 2021, so the absence of a judgment is weak evidence and a judgment found is strong evidence. Where the supplier claims an export record, its customs registration is checked on the customs credit platform, and where a tax credit rating is published, an A rating is noted and a D rating is a hold.

A single old judgment is read in context. A pattern of enforcement entries, or a legal representative who appears on the dishonest-debtor roll through another company, stops the file.

4. Match the money to the company

The beneficiary named on the bank details must be the licensed company, or a Hong Kong invoicing company whose link to the factory is documented in the file and whose own record is read at the Hong Kong Companies Registry. A personal account, a third-party trading company, or an account in another city with no documented link is an automatic hold. The name on the value-added-tax invoice is matched to the licence for the same reason.

Bank details that change after the order is agreed are not accepted from the same email thread. The instruction is confirmed with the registered company through a separate channel, because a beneficiary changed by email is a known diversion pattern; that call-back confirms the instruction, not who owns the account, which only a bank confirms. The pre-payment due diligence check runs this step as a defined assignment before a deposit, and the guide on a supplier’s changed bank details covers the late change.

5. Establish whether the supplier manufactures or resells

The registered business scope (经营范围) is the first test. A manufacturer’s scope names the production activity; a trading company’s reads as wholesale, retail or import and export. Six further indicators narrow the harder cases: the registered address against the address where production is claimed; the VAT invoice, which a factory issues under its own name; the catalogue, since a factory makes a narrow range and a trader lists a wide one; the minimum order quantity, which a factory sets from its line and a trader from its margin; the location, because production of a given equipment type clusters in known regions; and the company name on any audit report the supplier offers. ISO 9001 is a weak signal here, as some traders hold it. None of these is proof on its own; the production line is.

A trading company is not a disqualification when the order is best served by one. It is a hold when it was presented as the factory, because every downstream control, from the audit to the final balance, would then point at the wrong company; the file reopens only on the registry record of the manufacturer actually behind the offer and a contract that names it.

6. Evidence the capacity and the capability

A clean record and a good sample still say nothing about whether the line can deliver the quantity on the date. The evidence is the production line itself: the equipment in service, the number of lines and shifts, the workforce on the floor, the steps that are subcontracted and to whom, and the real daily output against the figure in the quotation. A live video walk-through, with the supplier’s phone moving from the gate to the line to the test bench, settles most files. An on-site audit follows where the order value, a custom specification or an unknown supplier warrants it; the factory audit checklist sets out the nine areas the visit covers.

7. Check certificates, test reports and samples at their source

A certificate is a claim until the issuer confirms it. ISO certificates are checked with the certification body, in its register where one exists, and cross-referenced in IAF CertSearch where the body lists its certificates there. Where the CE route needs a notified body, its number and scope are checked in NANDO. Type-test reports that rely on accreditation are read against the laboratory’s accredited scope, and the full report is requested, never the cover page, because the cover page does not show the model, the sample or the result. The supplier technical file checklist is the working tool for matching every document back to the same model, factory, version and batch. Factory audit reports are read the same way: factory audit reports that state the auditing organisation, date and scope are evidence of a visit, not a substitute for one. Inspection reports are contracted on your own order; another client’s operational report is not a qualification prerequisite.

The approved sample is recorded with its specification, material, version and test result, and kept as the reference against which production is later inspected. The quotation is compared line by line with the specification, including packing, documentation, testing and the delivery point, rather than by unit price; the guide on quotation warning signs lists the patterns that matter.

8. Contact the references and record the decision

Reference installations are named, dated and contacted, and the answers are written down rather than paraphrased. A reference that cannot be named or reached is recorded as such.

The file then closes in one of three states: qualified; qualified with conditions written into the order, such as a pre-shipment inspection or a payment milestone tied to a test; or disqualified, with the finding that failed it. The evidence pack holds the registry extract, the risk-record searches, the payment-path match, the certificate confirmations, the sample record, the quotation comparison, the desk review of the manufacturing evidence, the visit findings and the reference notes, so that an engineer, a bank or a partner can read the decision without redoing the work. Where several candidates clear, the supplier comparison matrix puts the qualified offers on one basis before any price is compared.

Automatic hold conditions

  • The beneficiary on the bank details is a person, or a company other than the licensed supplier, with no documented link to it.
  • The business scope on the licence does not cover the equipment quoted, and the supplier presented itself as the manufacturer.
  • The registered address is a residential building, a virtual office or a shared workspace, and a candidate presenting itself as the manufacturer declares no production site.
  • Certificates that the named issuer does not confirm, that it confirms as expired, or whose numbers do not resolve in the issuer’s register.
  • The company or its legal representative appears on the dishonest-debtor roll, Credit China lists an open administrative penalty relevant to the order, a published tax credit rating reads D, or the entity or its legal representative appears on a sanctions or restricted-party list that applies to the buyer’s market; a listing disqualifies the candidate outright.
  • Production steps that determine quality are subcontracted and the subcontractor is not named.
  • A reference cannot be named, dated or reached, or the supplier declines a video walk-through or a factory visit that was agreed.
  • Bank details change after the order is agreed, by email, before the registered company has confirmed them through a separate channel.

A hold is not a rejection, with one exception: a sanctions or restricted-party listing disqualifies the candidate outright. Every other hold is the point where the file stops until the supplier clears it, and the clearing evidence goes into the record. Three holds on the same supplier that remain open after a written request are usually the end of that candidate.

Desk, video or site: the depth that fits the order

Steps two to five, seven and eight are desk work. Steps two and three close within days of the registered name being known; steps four, seven and eight close as the bank details, certificates, sample, quotation and reference contacts reach the file; step five is recorded provisionally from the invoice or catalogue and confirmed at step six. Step six is where the depth is chosen: a video walk-through for a repeat supplier of commodity equipment with verifiable references, an on-site audit for higher-value, custom or unfamiliar work. The supplier evaluation service page sets out the three assignments, their fees and their turnaround.

The method in two published cases

Two case studies show the steps at work on real orders: engine power packs sourced through the maker’s own channels, where the supply route was traced back to the manufacturer before the order was placed, and glass container samples kept as the reference for the production check, where the approved sample of step seven became the yardstick for the inspection that followed.

How Sinospect runs the evaluation

Sinospect runs supplier evaluation on behalf of industrial buyers and EPC procurement teams sourcing from China, against the eight steps above, and reports each file in the same order. The scope covers registry verification, the public risk records, the payment-path match, document review, certification authentication, reference checks, and a video walk-through or factory visit where the order warrants one, each visit reported in the structure described in the China supplier visit report guide. The output is a written shortlist of qualified suppliers, with each disqualified candidate documented and the reason recorded. Before a deposit leaves your account, the pre-payment due diligence check reads the contracting company and any Hong Kong company that invoices for it at the official registers and compares the payment instructions with those records.

Frequently asked questions

How do you check whether a Chinese supplier is legitimate?

Start with the licence. Ask for the business licence, read its 18-character Unified Social Credit Code in GSXT, and confirm that the registered name matches the quotation, that the business scope covers the equipment and that there is no abnormal-operation entry. Then search the company and its legal representative on China Judgements Online, the enforcement platform and Credit China, and match the beneficiary on the bank details to the licensed company, or to a documented Hong Kong invoicing company read at its own register. A supplier that clears those four checks exists as registered, with no published judgment, enforcement entry or penalty found, and with a payment path that leads to it; what the public records do not publish stays unproven. Whether it can build the equipment is the next question, and it is answered at the production line, not at the registry.

What are the five key supplier evaluation criteria?

Legal identity at the registry and the absence of published adverse records; the payment path, meaning that the beneficiary on the bank details matches the licensed company or its documented Hong Kong invoicing company, a documentary match, with account ownership confirmed by the bank; manufacturing role and capacity, meaning that the party behind the offer is known, factory or disclosed trading company, and that the line behind it can build the order; certificates, test reports and samples that hold up at their source; and a delivery record proven by contactable references. The eight steps on this page are those five criteria in working order, with the decision recorded at the end.

Can a buyer rely on Alibaba’s Verified Supplier or Gold Supplier badges?

No. Those labels indicate the supplier has paid for a verification service or a membership tier on the platform. They do not certify production capability, certification authenticity, financial standing, or willingness to honour a delivery. Independent qualification is required regardless of any platform badge.

Is a factory audit always necessary?

For higher-value equipment, custom specifications, or unfamiliar suppliers, yes. For commodity equipment from well-established suppliers with strong reference installations and verifiable documentation, a live video walk-through can close the capacity step. The decision is made at step six, project by project, and the reason is written into the record.
