Direct answer

GB can be mandatory or recommended — the legal hook is usually a regulation, CCC rule or contract that points to it.

Guobiao (GB) standards are China’s national standards; GB/T are often recommended but can become binding through regulation or agreement. Product design, testing and labelling frequently cite specific GB numbers. This wiki orients GB. CCC certification is how many mandatory safety standards are enforced at the gate. Product liability claims may use GB as a defect benchmark. Keep version control — withdrawn standards are a classic audit miss.
