Compliance overview
Scope and applicability
This standard applies to feed additive dicalcium phosphate produced via chemical synthesis using wet-process phosphoric acid and calcium compounds, or through the hydrolysis of calcium phytate. It covers the classification, technical requirements, and testing methods for this specific mineral feed additive. Manufacturers supplying dicalcium phosphate to the Chinese animal feed industry must comply with this mandatory standard. It replaces the previous GB 22549-2017.
Technical requirements
The standard classifies dicalcium phosphate into three types (Type I, Type II, and Type III) based on the production process. It specifies the physical appearance, requiring the product to be a white, gray, or slightly yellowish powder or granule. Products must pass specific identification reactions for calcium ions and phosphate radicals. Regarding physicochemical parameters, the standard sets minimum requirements for total phosphorus, citrate-soluble phosphorus, water-soluble phosphorus, and calcium content. It also regulates free moisture and fineness to ensure proper handling and mixing in feed formulations. Specific numerical limits vary depending on the product type. Furthermore, the standard establishes strict hygiene indicators to ensure feed safety. It defines maximum limits for heavy metals and toxic elements, including fluorine (F), total arsenic (As), lead (Pb), cadmium (Cd), and chromium (Cr). Compliance with these safety limits is critical for market access.
Testing methods
The standard outlines specific testing procedures to verify compliance. Total phosphorus, citrate-soluble phosphorus, and water-soluble phosphorus are determined using the quinoline phosphomolybdate gravimetric method. Calcium content is measured via EDTA complexometric titration. Heavy metals and toxic elements such as fluorine, arsenic, lead, cadmium, and chromium are tested according to referenced national standards like GB/T 13083 and GB/T 13079. Accurate testing is essential to prove conformity with the technical specifications.
FAQs
What products are regulated under GB 7300.313-2025?
It regulates feed additive dicalcium phosphate, specifically those produced from wet-process phosphoric acid and calcium compounds, or from calcium phytate.
