Start with the business license: every legitimate Chinese company has a Unified Social Credit Code. Ask for a copy and verify it on the National Enterprise Credit Information system or via your freight forwarder. Check that the business scope includes 'used car export'—this requires specific qualifications. Next, look for proof of substance: a real office or yard (verify via live video call, not pre-recorded), staff answering on Chinese business platforms like WeChat with consistent branding, and a corporate bank account in the company's name—never pay a personal account. Cross-check trade history: ask for recent shipping documents (blurred bills of lading with customer info hidden), references from buyers in your region, and whether they hold export licenses issued by Chinese commerce authorities. Red flags: prices far below market, pressure to pay quickly, refusal of video calls, or bank accounts in third countries 'for convenience'. Take your time—real exporters pass these checks easily.

For older vehicles or those used in high temperature and humidity areas, we will focus on opening the hood to check if the insulation of the wiring harness in the high-temperature area of the engine compartment is cracked or brittle, to identify potential short circuit risks that could lead to spontaneous combustion.

A normal transaction moves through six stages. First, selection and verification: you shortlist cars, request VIN-level documents, and order an independent inspection (1-2 weeks). Second, contract signing and deposit: 10-30% is standard, paid against a signed contract listing the VIN and agreed spec. Third, export preparation: the seller handles deregistration and export licensing (1-3 weeks). Fourth, final payment against loading: pay the balance only after you receive the bill of lading or rail waybill number you can track. Fifth, transit: ocean shipping to most ports takes 3-6 weeks, rail to Central Asia or Europe 2-4 weeks. Sixth, destination clearance and registration: allow 1-2 weeks plus buffer for inspections. In total, plan for 2-4 months door to door. Any exporter promising full delivery in under six weeks is likely cutting corners on export paperwork.
