1 Scope

GB/T 22144-2025 is the Chinese national standard covering the mineral materials fed to animals - limestone, phosphates, salt, zeolites and clays - with their identification, their nutrient content and the heavy metals and fluorine that come with a natural mineral and have to be limited. It replaces GB/T 22144-2008, one of four feed standards revised together. It was issued on 31 December 2025 and has been in force since 1 July 2026, replacing GB/T 22144-2008. The document is under the responsibility of the Standardization Administration of China. This page is published from the official record of the 2025 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the technical requirements, inspection rules, labeling, packaging, transportation, storage, and shelf life of natural mineral feed ingredients, and describes... Sampling and testing methods. This document applies to natural mineral feed ingredients.
