According to Article 12 of the Standardization Law of China:
Sector standards may be developed for technical requirements that lack voluntary national standards and need to be unified within a certain industry across the country.
Sector standards shall be developed by the relevant administrative departments of the State Council and filed with the administrative department of standardization of the State Council.
Different government departments are expected to continually draft sector standards based on their responsibilities. All of those sector standards will be reported to SAC for recording. Currently, sector standards are still playing an important role in China, 70 industries in China still rely on sector standards. According to the 2020 China Standardization Report made by Mr. TIAN Shihong, in 2019, 3 new sector standards Codes had been approved including fire rescue, emergency management and national material reserve, 4880 new sector standards have been reported to SAC for recording, and 2665 sector standards have been annulled.
