All our measuring instruments (especially calipers, paint thickness gauges, and refrigerant pressure gauges) are calibrated quarterly according to ISO quality management system requirements to ensure the data we provide you is objective, accurate, and reliable.

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.

Europe and some developed countries have very strict regulations on greenhouse gases. If required by customs, we will specify the exact refrigerant type and charge amount according to the vehicle's air conditioning compressor nameplate in the remarks section of the packing list and commercial invoice.
