From a technical perspective, China's "National VI B (China VI-b)" is one of the strictest emission standards globally, with limits on carbon monoxide, nitrogen oxides, and particulate matter that are even stricter than some of Europe's Euro VI standards. However, the two are not legally recognized by each other, depending on your country's import regulations.

A cold start reveals problems that a warm engine hides. Ask your inspection agent to perform and film this sequence. First, the start itself: the engine should crank smoothly and settle into a stable idle within a few seconds. Extended cranking, blue or white smoke, or a lumpy idle suggest worn internals or head-gasket issues. Second, listen for timing-chain rattle or metallic tapping in the first ten seconds — cold top-end noise often means deferred maintenance. Third, watch the exhaust on a cold morning: brief white vapor is normal in winter, but persistent blue smoke means oil burning, and sweet-smelling white smoke can indicate coolant leaking into the cylinders. Fourth, have the inspector scan the OBD system right after the cold start; misfire counters and fuel-trim values are most honest when the engine is cold. Ask for a continuous, timestamped video from outside the car before startup through at least five minutes of idling, so you can verify the engine really was cold.

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.
