A Chinese VIN is 17 characters, and decoding it takes minutes but reveals a lot. Positions 1-3 are the World Manufacturer Identifier. Cars sold domestically in China usually start with L (for example LFV for FAW-VW, LGB for Dongfeng Nissan), which tells you it was built in China rather than imported. Position 10 is the model year letter or number. Positions 4-8 describe the model, body type, and drivetrain, so you can verify the seller's description matches the actual car. Cross-check the VIN in three places: the plate at the base of the windshield, the sticker on the door jamb or B-pillar, and the registration certificate. Mismatched VINs or signs the plates were re-riveted are a serious red flag for a cloned or rebuilt vehicle. Use the VIN to pull a history report from a Chinese data provider and to verify recall status with the manufacturer. Any seller who hesitates to share the full VIN is telling you something important.

A solid contract is your main protection in a cross-border deal. It should specify: 1. Vehicle identification: VIN, year, mileage, trim level, and photos of the actual car appended as an annex — not just「a 2021 Toyota」. 2. Condition guarantees: no accident, no flood or fire damage, no structural repairs, supported by a third-party inspection report referenced in the contract. 3. Price and Incoterm: total amount, currency, the named port, and whether freight and insurance are included. 4. Payment schedule: e.g., 20–30% deposit after contract signing, balance against copy of the Bill of Lading. Avoid 100% upfront. Use T/T to the company's corporate bank account only — never a personal account. 5. Timeline: inspection date, estimated loading date, and latest shipment date, with remedies if delayed. 6. Dispute clause: governing law and arbitration (CIETAC or your local chamber) rather than foreign court litigation. Ask for the contract in English (or bilingual) with the supplier's company chop. A company that refuses a written contract or pushes for full prepayment is a red flag.
