Compliance overview
Scope and applicability
This standard applies to motor vehicles and their incomplete vehicles, trailers, motorcycles, and mopeds. It is mandatory for all vehicle manufacturers entering the Chinese market. Other vehicles requiring a Vehicle Identification Number (VIN) may refer to this standard.
Technical requirements
GB 16737-2019 specifies the content and structure of the World Manufacturer Identifier (WMI) code, which forms the first part of the VIN as defined in GB 16735. The WMI code consists of three characters using specific Arabic numerals and uppercase Roman letters (excluding I, O, and Q). The first character identifies a geographic region, while the second identifies a specific country within that region. For China, the assigned combinations include L0-L9, LA-LZ, H0-H9, and HA-HZ. The third character identifies the specific vehicle manufacturer. Manufacturers with an annual production of less than 1000 vehicles must use the number 9 as the third character. In such cases, the authorized organization will also assign characters for the 12th, 13th, and 14th positions of the VIN to ensure uniqueness.
Testing methods
This standard does not involve traditional physical testing methods. Instead, it outlines the administrative and coding evaluation procedures for WMI assignment. Manufacturers must submit an application to the authorized organization, detailing vehicle type, brand, and annual production capacity. Import vehicle manufacturers must register their existing WMI codes with the authorized organization.
