This standard is a supplementary standard to GB 2763. It specifies the scope, normative references, terms and definitions, maximum residue limits (MRLs) of pesticides in food, as well as the corresponding testing methods. It establishes 290 MRLs for 112 pesticides, including 2,4-D dichlorophenoxybutyric acid salt, in various food categories.

The Annex A (Normative Appendix) Food Categories and Testing Parts defined in GB 2763-2021 also apply to this standard. In cases where an MRL for the same pesticide and food differs between GB 2763-2021 and this standard, the provisions of this standard shall prevail
