1 Scope

GB 7300.403-2022 is the Chinese national standard on feed additives - part 4: enzymes - cellulase, in the field of agriculture. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 29 December 2022 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 January 2024. Classification: ICS 65.120, CCS B46. 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 specifies the technical requirements, sampling, inspection rules and labeling, packaging, transportation, storage and quality assurance of feed additive cellulase period, describing the test method. This document is applicable to the fermented strains specified in the "Catalogue of Feed Additives", separated and purified, with or without carriers Feed additive cellulase.
