Verify the company, the product and the transaction separately
Before ordering from a Chinese auto-parts supplier, verify three different things: that the legal business exists, that the quoted source can supply the required parts, and that the proposed transaction is internally consistent. A registration document alone does not prove product capability, while a good sample does not prove that the bank account belongs to the contracting company.
Ask for the supplier’s full Chinese and English company names, unified social credit code, registered address, business license and invoice or contract entity. Compare those details across the quotation, email signature, website and payment instructions. Differences may have an innocent explanation—such as a manufacturer using an export company—but the relationship should be stated and documented before payment.
Use the exact legal name when checking public corporate records or asking a local verification provider to help. A trading company is not automatically a problem. The important point is knowing who contracts with you, who manufactures the product and who receives the money.
Check capability against your actual SKU list
Do not ask only whether the supplier “does Chery parts” or “does brake parts.” Send a representative list with OEM numbers, vehicle details, quantities and target market. Ask the supplier to mark which lines are manufactured, sourced, uncertain or unavailable. A credible answer may contain gaps. A supplier claiming immediate certainty across every category deserves closer review.
Request evidence relevant to the products: catalogue data, product labels, packaging examples, photos from consistent angles, critical dimensions and sample availability. For fitment-sensitive items, provide VIN, EPC context or original-part photos. Check whether the returned information answers your references rather than replacing them with vaguely similar products.
PartSail states an MOQ negotiable from 100–200 sets per SKU and support for mixed containers. It also states a 15–35 day lead time depending on quantity and customization. Use these numbers as disclosed capability, then obtain line-specific terms in the quotation. An unusually low minimum or very short schedule should be explained by stock, shared production or another concrete condition.
Validate certificates rather than collecting logos
Ask for the certificate file, certificate number, issuing body, holder name, site address, scope and validity date. Compare the holder with the proposed manufacturer and check the issuer’s verification channel where available. A logo on a brochure is not evidence.
PartSail lists IATF 16949:2016, ECE R90, ISO 9001:2015 and CE among its available certifications. These cover different subjects and cannot be treated as interchangeable. IATF 16949 and ISO 9001 concern management systems and scope; ECE R90 concerns specified replacement braking products and applications; CE relevance depends on the product and applicable rules. Ask which document supports the exact SKU and destination requirement.
Watch for cropped certificates, inconsistent company names, missing annexes, expired dates or a scope unrelated to the quoted goods. When regulation matters, have your compliance adviser or importer verify the requirement independently. The importer remains exposed if the supplied paperwork is irrelevant or invalid.
Use samples and inspection as evidence
A paid sample lets you check identification, dimensions, workmanship, connector position, markings and packaging before committing to a batch. PartSail states that paid samples are available and the sample cost can be refundable against bulk orders. Confirm the sample price, freight and credit condition in writing. Photograph and label the approved sample so it can serve as a comparison reference.
A sample proves only the sample. For the production order, agree on an inspection plan covering SKU, quantity, packaging, labels, visible defects and critical measurements. Decide whether inspection occurs during production, before shipment or both. For mixed containers, use a packing-list reconciliation so one correct line does not hide a shortage or substitution elsewhere.
If the order includes private-label packaging, approve artwork, color, barcode, carton marks and part marking before mass printing. Keep approval files linked to the purchase order and require written approval for substitutions.
Review commercial and payment consistency
The quotation should identify currency, Incoterm, unit basis, quantities, MOQ, packaging, lead time, payment terms, validity and whether freight or local charges are included. Compare beneficiary name and country with the contract entity. Treat a late request to pay a different personal or unrelated account as a stop signal until independently verified through a known contact channel.
Confirm changes by calling a previously verified number, not a number contained only in the change request. Use controlled company payment procedures and have a second person review beneficiary details. Email compromise can affect legitimate suppliers, so payment verification is necessary even after a relationship has begun.
Also ask how claims, shortages and wrong-part cases are documented. The answer should describe evidence and handling steps, not rely on a broad promise that “all quality is guaranteed.”
Run a small, traceable first transaction
A sensible first order tests the whole workflow: catalogue response, sample handling, quotation accuracy, production communication, inspection, documents and shipment. Choose commercially useful SKUs, but avoid making the first transaction larger than your ability to inspect and sell. Mixed-container support can help diversify the trial, provided each line is still identified and counted.
Keep a verification file containing registration evidence, certificate checks, contact details, approved references, quotation versions, payment confirmation and inspection results. Recheck time-sensitive items such as certificates and bank details on later orders.
No single document proves a supplier is reliable. The strongest conclusion comes from consistent evidence across legal identity, product knowledge, samples, certification scope, commercial terms and delivered goods. Verification is therefore a process, not a badge: each step reduces a different risk before your capital and reputation are committed.
