GB/T 29632-2013

This standard specifies the categories of major parts covered under the repair, replacement, and return (three-guarantee) warranty for household automobile products, along with the format and content requirements for the warranty certificate. It is applied by Chinese automotive manufacturers and dealers to define which components (e.g., engine, transmission, body) are subject to mandatory warranty obligations under national consumer protection regulations. The standard ensures consistent disclosure of warranty terms to consumers during vehicle sales and service transactions.
