Compliance overview
Scope and applicability
This standard applies to feed additive potassium iodide produced via the formic acid reduction method using iodine and potassium hydroxide as raw materials. It is mandatory for manufacturers producing this specific mineral feed additive for the Chinese market. The standard does not apply to potassium iodide produced by other methods or intended for non-feed applications. Compliance is verified according to GB 7300 series regulations.
Technical requirements
The standard specifies stringent technical requirements for potassium iodide used as a feed additive. Key parameters include appearance, requiring the product to be a white crystalline granule or powder, and specific identification tests for iodide and potassium ions. Manufacturers must ensure the product meets mandatory limits for heavy metals and purity. The standard outlines maximum allowable limits for heavy metals such as lead, cadmium, arsenic, and barium. Additionally, it sets requirements for physicochemical properties, including drying loss, iodate content, pH value, solubility, and fineness. All technical indicators must conform to the defined thresholds to ensure product safety and efficacy in animal nutrition.
Testing methods
The standard details specific testing methodologies to verify compliance with the technical requirements. This includes titration methods for determining potassium iodide and iodine content using potassium iodate standard solutions. Heavy metal content, such as lead and cadmium, is measured using atomic absorption spectrophotometry as specified in GB/T 13080. Arsenic content is determined via the silver salt method or arsenic spot method, while barium is assessed using a turbidimetric comparison method. Furthermore, the standard references GB/T 6435-2014 for drying loss determination and specifies procedures for pH, solubility, and fineness tests.
FAQs
What products are regulated under GB 7300.301-2019?
