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.

The registration certificate will show whether the previous owner was an individual (registered with ID) or a company (registered with a business license). Vehicles under a company may be driven by multiple people, so we will focus on checking the uniformity of interior wear and the condition of the chassis.

Odors are difficult to convey through images, so our quality inspectors conduct subjective smell assessments and record them. For vehicles with severe smoke or mold odors, if deep ozone sterilization is ineffective, we will downgrade the vehicle and mark the report with a red "Odor Warning" at the top.
