Compliance-Überblick

Dieser Überblick ist derzeit nur auf Englisch verfügbar.

Geltungsbereich und Anwendbarkeit

This standard applies to feed additive manganese methionine complex (chelate) synthesized from soluble manganese salts and methionine with a molar ratio of 2:1 or 1:1. It is mandatory for manufacturers producing or exporting these specific trace mineral feed additives to China. The standard covers requirements, testing methods, and inspection rules for both 2:1 and 1:1 molar ratio products.

Technische Anforderungen

The standard specifies mandatory technical requirements for manganese methionine complex (chelate), categorized into physical appearance and chemical composition. Appearance requirements dictate that the product should be a white or off-white powder without caking or mold. Chemical composition requirements include strict limits on active ingredient content (such as manganese and methionine percentages) and chelation rate. Furthermore, the standard sets safety limits for harmful substances, including moisture, particle size, total arsenic, lead, and cadmium. Compliance with these chemical and physical parameters is essential for market access. The standard also outlines rules for labeling, packaging, storage, and a 24-month shelf life, referencing GB 10648 for labeling compliance.

Prüfverfahren

The standard outlines specific testing methodologies to verify compliance. This includes sensory evaluation and chemical identification using PAN chloroform solution. Quantitative analysis involves titration methods for determining manganese content (using ammonium ferrous sulfate) and methionine content (using an iodometric back-titration). Additionally, it references national standards for testing moisture (GB/T 6435), particle size (GB/T 5917.1), heavy metals like arsenic, lead, and cadmium, as well as the chelation rate (GB/T 13080.2). Manufacturers must ensure their laboratory procedures align with these specified testing protocols.
