1 Scope

GB/T 22619-2023 is the Chinese national standard on bifenthrin technical material, in the field of agriculture. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 27 November 2023 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 June 2024. Classification: ICS 65.100.10, CCS G25. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document stipulates the technical requirements, inspection rules, acceptance and quality assurance period of bifenthrin technical materials, as well as the marking, labeling, packaging and storage This paper describes the test method for bifenthrin technical material: This document is applicable to the quality control of bifenthrin technical products:

Note: See Appendix A for other names, structural formulas and basic physical and chemical parameters of bifenthrin:
