Compliance overview
Scope and applicability
This standard applies to feed additive Vitamin D3 (powder form), including both ordinary and water-dispersible types. It covers products manufactured using Vitamin D3 oil as raw material, formulated with antioxidants and excipients like gelatin, starch, or maltodextrin. It is mandatory for manufacturers producing Vitamin D3 feed additives for the Chinese market.
Technical requirements
The standard specifies the physical and chemical requirements for Vitamin D3 powder feed additives. It defines product specifications, requiring a minimum concentration of 500,000 IU/g. The standard also outlines appearance criteria, noting that the product should be a free-flowing micro-particle that degrades upon exposure to heat, light, or moisture. Key technical indicators include the content of Vitamin D3 relative to the labeled amount, particle size distribution, and drying loss. Additionally, the standard introduces mandatory hygiene and safety limits for heavy metals, total arsenic, and chromium. The standard also differentiates between ordinary and water-dispersible types, setting specific dispersion requirements for the latter. Manufacturers must ensure their products meet these mandatory technical chapters to achieve compliance. Packaging, storage, and shelf life requirements are also specified, with ordinary products having a 24-month shelf life and water-dispersible products 12 months.
Testing methods
Testing methods include sensory inspection and chemical identification using color reactions. The Vitamin D3 content is determined via High-Performance Liquid Chromatography (HPLC) using either a saponification extraction method (Method 1, arbitration method) or an ultrasonic extraction method (Method 2). Other tests cover particle size analysis, drying loss, and specific assays for heavy metals, total arsenic, and chromium.
