Compliance overview
Scope and applicability
This standard applies to feed additive Cyanocobalamin (Vitamin B12) produced via microbial fermentation, purification, and crystallization. It is mandatory for manufacturers and importers of this specific vitamin product entering the Chinese market. It does not apply to other forms of Vitamin B12 or non-fermentation-derived products. The standard is part of the broader GB 7300 series for feed additives.
Technical requirements
The standard specifies the physical appearance, requiring the product to be a dark red crystal or crystalline powder. It mandates identification tests using UV-Visible spectrophotometry and Infrared (IR) spectroscopy to confirm the chemical identity. For physicochemical properties, the standard sets limits for the Cyanocobalamin content (calculated on a dry basis), related substances, loss on drying, and residual acetone. Manufacturers must ensure their product falls within these specified quantitative ranges to be compliant. Additionally, the standard establishes strict hygiene indicators for heavy metals, including maximum limits for total arsenic, lead, and cadmium. These requirements ensure the safety and purity of the feed additive for animal consumption.
Testing methods
Testing involves UV-Visible spectrophotometry for content determination and identification, utilizing specific absorbance ratios at 278 nm, 361 nm, and 550 nm. High-Performance Liquid Chromatography (HPLC) with a C18 column is used to quantify related substances. Gas Chromatography (GC) with a headspace sampler and FID detector is employed to measure residual acetone. Heavy metals (As, Pb, Cd) are tested according to referenced national standards like GB/T 13079 and GB/T 13080.
FAQs
What products are regulated under GB 7300.209-2025?
It regulates feed additive Cyanocobalamin (Vitamin B12) specifically derived from microbial fermentation. It does not cover other vitamins or feed additives in the GB 7300 series.
When does GB 7300.209-2025 come into effect?
The standard was issued on December 31, 2025, and will be mandatory starting from January 1, 2027. Manufacturers must ensure compliance before this implementation date.
What are the key safety parameters tested in this standard?
The standard tests for heavy metals including total arsenic, lead, and cadmium, along with residual solvents like acetone, ensuring the product is safe for animal feed.
