1 Scope

GB 7300.301-2019 is the Chinese national standard on feed additives - part 3: minerals and their complexes (or chelates) - potassium iodide, 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 17 December 2019 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 July 2020. 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 part of GB 7300 specifies the technical requirements, test methods, inspection rules, labels, signs, packaging, transportation Loss, storage and shelf life. This section applies to feed additive potassium iodide produced by formic acid reduction method using iodine and potassium hydroxide as raw materials.
