1 Scope

GB 7300.304-2024 is the Chinese national standard on feed additives - part 3: minerals and their complexes (or chelates) - ferrous glycine complex, 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 September 2024 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 October 2025. 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 gives the chemical name, molecular formula, relative molecular mass and structural formula of glycine iron complex and specifies the feed additive glycine iron complex. The technical requirements, sampling, inspection rules, labeling, packaging, transportation, storage and shelf life of iron-amino acid complex are described, and the test methods are described. This document applies to feed additive glycine iron complex products which are chemically synthesized from glycine and ferrous sulfate.
