How to Verify a Chinese Construction Machinery Supplier Before You Pay: 7 Steps That Actually Work

The first hour of due diligence on a Chinese machinery supplier is worth more than the last month of negotiation. Here is the checklist we would run on any supplier, including our own competitors.

Why the website is not the verification

A polished website, an Alibaba Gold Supplier badge, and a WeChat contact are table stakes — they cost USD 200-2000 to set up and do not reflect the actual operation behind them. The seven steps below are the ones that take more than a credit card to fake.

Step 1 — the National Enterprise Credit Information check

Look the company up on the National Enterprise Credit Information Publicity System (NECIPS) at gsxt.gov.cn. Three things to confirm: the company is “存续” (still in business, not dissolved or revoked); the registered capital is at least RMB 1 million for a machinery exporter; and the legal representative on the registration matches the person signing your contract. If the legal representative on the registration is different from your contact, ask why.

Step 2 — the export license and HS code coverage

A company exporting construction machinery needs both a customs registration code and the relevant HS code coverage. The relevant HS codes for the machines we export are 8426 (lifting machinery), 8427 (fork-lift trucks), 8429 (self-propelled bulldozers, graders, scrapers), and 8430 (other moving, grading, scraping or excavating machinery). If the company’s customs record does not show any of these codes in their recent export declarations, they are not actually exporting the category of equipment they are selling.

Step 3 — the third-party trade database check

Panjiva, ImportGenius, 52WMB, and 17TRACK all carry Chinese export records. A search by company name (Chinese and English) will return the recent shipments: destination countries, buyer names, declared values, and shipping lines. A company that has actually shipped 50+ machines in the last 24 months will show up; a trading-front that opened a year ago will show one or two shipments or nothing at all. We have a public shipment history available on request — a normal part of the due-diligence conversation.

Step 4 — the factory visit (or the refusal)

A pre-shipment factory visit is the gold standard. If the supplier refuses, asks you to come to a different city than the one on the registration, or asks for an “inspection fee” before letting you visit — these are strong signals that the company is a trading front, not a manufacturer. Our 29-checkpoint inspection takes about 10.6 hours per machine and we host buyers who want to witness it in person at our Xingyang facility.

Step 5 — the certificate of origin and the export declaration

Every shipment from China carries a certificate of origin and an export declaration. The certificate of origin shows the producer (or the exporter of record) and is counter-signed by the China Council for the Promotion of International Trade (CCPIT). The export declaration is filed by the customs broker and shows the actual declared value, the HS code, and the destination. Ask the supplier for sample copies — redacted is fine — and verify the format matches the standard CCPIT template.

Step 6 — the reference buyers and the call-back

Any legitimate exporter can name three buyers in three different countries who will speak to a serious prospective buyer. Ask for the names, the countries, the units shipped, and the dates. Then contact the buyers — not the suppliers’ reference, but a separately-sourced contact (LinkedIn search, industry associations, the buyer’s own company website). A reference that cannot be independently reached is not a reference.

Step 7 — the written deliverable specification

The single most important document in any deal is the written specification that ties the payment to a deliverable condition. If the supplier cannot write down, in a contract, exactly what “as-is” or “refurbished” or “remanufactured” means for the specific unit — paint, tyres, battery, hydraulics, hours, undercarriage percentage, and the document the buyer will receive — that is a clear signal that the deal will be decided by whatever the unit happens to be on the day of shipment. We publish a 4-level delivery standard that is short enough to put into a contract.

What you should walk away with

A 60-minute supplier verification should leave you with: a NECIPS record, a customs-export history, a HS-code coverage confirmation, a list of three independently-verifiable references, a sample certificate of origin, and a written deliverable specification in a contract that names the unit, the condition, the price, the payment terms, and the inspection right. Anything less than that, and the price should reflect the missing assurance.

This checklist is informational. Specific situations depend on the unit, the destination, and the parties. For a specific transaction, a qualified commercial lawyer in both jurisdictions is the right place to start before any payment is made.
