GB/T is a recommendatory standard, which is also approved and issued by the national standardization authority and recommended for implementation nationwide. They are national standards that are adopted voluntarily in production, exchange, use and other aspects through economic means or market regulation (hence, they are also called voluntary standards). For example, GB/T34926-2017 Mica Tape Mineral Insulated Corrugated Copper Sheathed Cables and Terminations with Rated Voltages of 0.6/1kv and Below. Any unit shall have the right to decide whether to adopt such standards. Violation of such standards shall not bear any economic or legal responsibility. However, once accepted and adopted, or included in the economic contract as agreed by all parties, it will become the technical basis that all parties must abide by, which is legally binding.

Chinese standards are divided into four levels: national standards (GB), industrial standards (HB), local standards (DB) and enterprise standards (Q/). The "ministerial standards" formulated by the competent ministries can be GB or HB according to their level.
