Compliance overview
Scope and applicability
This standard is applicable to feed additives specifically formulated as cupric methionine complex (chelate) with a molar ratio of 2:1. Chapters 1, 3, and 5 of this standard are mandatory for manufacturers and importers. It does not cover other molar ratios or different types of copper methionine products.
Technical requirements
The standard specifies the physical appearance and chemical composition requirements for the cupric methionine complex. The product must appear as a blue-purple powder, slightly soluble in water, without any caking or mold. Key technical indicators include minimum thresholds for copper content and methionine content, as well as a strict minimum requirement for the chelation rate. Furthermore, the standard sets maximum limits for moisture, heavy metals (such as total arsenic and lead), and specific particle size distribution. Compliance with these chemical and physical parameters is mandatory to ensure product safety and efficacy in animal feed.
Testing methods
The standard outlines several analytical procedures to verify compliance. Copper content is determined using an EDTA titrimetric method, while methionine content is measured via an iodometric titration. The chelation rate is evaluated according to the methods specified in GB/T 13080.2-2005. Additionally, tests for moisture, total arsenic, lead, and particle size are conducted by referencing established national standards such as GB/T 6435, GB/T 13079, and GB/T 5917.1. Manufacturers must perform both factory and type inspections to validate these metrics.
FAQs
What products are regulated under GB 20802-2017?
GB 20802-2017 regulates feed additives that are cupric methionine complex (chelate) with a specific molar ratio of 2:1. It is mandatory for all such products entering the Chinese market.
Are there any updates from the previous version of this standard?
Yes, compared to the previous GB/T 20802-2006, this version adds requirements for water solubility and chelation rate, and removes content related to the 1:1 molar ratio product. It also tightens limits for moisture and lead content.
What is the shelf life specified in the standard?
Under the specified transportation and storage conditions, the standard stipulates a shelf life of 24 months for the cupric methionine complex.
