The standard set is: 1. Commercial invoice and sales contract - issued by the exporter; the basis for customs valuation. 2. Packing list - exporter; details the vehicle and any spare parts shipped with it. 3. Bill of lading - issued by the shipping line; your proof of ownership of the cargo. Never pay the full balance before receiving at least a copy of it. 4. Certificate of origin - issued by the China Council for the Promotion of International Trade (CCPIT); some countries require it for preferential duty rates. 5. Export customs declaration - Chinese customs; confirms the car was legally exported. 6. Pre-shipment inspection report - issued by companies like Intertek, SGS or the EAA scheme, if your country mandates it. Ask the exporter for scanned copies of all documents before shipping so you or your broker can verify completeness.

Vetting takes a day and can save you thousands. Work through this checklist. Verify the business: ask for the company registration number and check it on China's National Enterprise Credit Information system or a commercial registry tool. Confirm the registered address matches where they claim to operate, and that their business scope includes vehicle export. Check export credentials: they must hold a used-vehicle export license issued by Chinese commerce authorities. Ask for the license and a recent export declaration showing they actually ship cars. Test their knowledge: a real exporter answers detailed questions about your destination country's import rules (age limits, left/right-hand drive, emission standards) without hesitation. Vague answers about your own country's requirements are a red flag. Structure payments safely: small deposit (10-20%), balance only against inspection reports and shipping documents, ideally through a payment method with recourse. Refuse full prepayment by irreversible transfer—no legitimate exporter requires it.

Comparing quotes properly means comparing the same thing: 1. Normalize the scope: some quotes include inland transport, export clearance, inspection and ocean freight, others are FOB only. Ask each exporter for a line-item breakdown so you can compare like with like. 2. Check what is excluded: port charges at destination, customs duties, homologation and registration are almost always on you. Get a written list of everything NOT included. 3. Look beyond the number: a quote 10-15% below the market usually means the car has an issue (accident history, rolled-back mileage, pending lien) or the exporter plans to cut corners on inspection and loading. 4. Verify the exporter: business license, export qualification, recent shipment records, and references from buyers in your region. A realistic quote from a verifiable exporter is worth more than a bargain that turns into a dispute. Always pay against milestones with inspection before balance payment.
