GB 7300.306-2025 is an upcoming mandatory Chinese national standard for Feed additive—Part 3: Minerals and their complexes (or chelates)—Chromium nicotinate. It appears in the Food compliance cluster with a product safety focus and has an implementation date of Jul 1, 2026.
Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard applies specifically to feed additive chromium nicotinate, which is synthesized through the reaction of chromium trichloride and nicotinic acid. It is designed for manufacturers and distributors involved in the animal nutrition and feed additive industry. This standard is mandatory for all production and compliance assessments of chromium nicotinate entering the Chinese market.
Technical requirements
The standard specifies comprehensive technical requirements for chromium nicotinate, categorized into appearance, identification, physicochemical, and hygienic parameters. The product must appear as a light gray to blue-gray powder and pass specific infrared spectroscopy identification tests. For physicochemical requirements, the standard sets strict thresholds for active ingredient purity, total chromium content, and limits for toxic forms such as inorganic chromium and hexavalent chromium (Cr(VI)). It also regulates particle size and drying loss to ensure physical stability. The hygienic parameters strictly limit hazardous heavy metal contaminants, including total arsenic, lead, cadmium, and mercury. Compliance with these safety thresholds is critical for product approval.
Testing methods
Testing procedures involve visual inspection for appearance and infrared spectroscopy for molecular identification. Quantitative analysis of total and inorganic chromium is conducted according to NY/T 2770, while hexavalent chromium testing follows the methods specified in HG/T 4837-2015. Heavy metal safety testing for arsenic, lead, cadmium, and mercury strictly references national standards such as GB/T 13079 and GB/T 13080.
FAQs
What products are regulated under GB 7300.306-2025?
This standard regulates chromium nicotinate, a mineral element complex used as a nutritional feed additive. It applies specifically to the product synthesized via the reaction of chromium trichloride and nicotinic acid.
What are the key safety limits for heavy metals and toxic chromium forms in this standard?
The standard mandates strict limits on inorganic chromium and hexavalent chromium (Cr(VI)) to ensure product safety and proper chemical formation. It also sets maximum limits for heavy metals like arsenic, lead, cadmium, and mercury.
How does GB 7300.306-2025 relate to other testing standards?
The standard references several foundational GB and industry standards for testing, such as GB/T 13079 for arsenic and NY/T 2770 for organic chromium determination. Manufacturers must strictly adhere to these referenced methodologies for valid compliance testing.
