適用範囲

This standard applies to feed additive choline chloride, specifically encompassing both liquid solutions (water agents) and powder formulations. The powder variants are differentiated by their carriers, primarily including plant-derived carriers or silica dioxide (SiO2) carriers. It is mandatory for all manufacturers producing or exporting choline chloride feed additives to the Chinese market.

技術要求

The standard specifies comprehensive technical requirements for choline chloride, categorized into appearance, physicochemical, and hygiene indicators. For appearance, water agents must be colorless transparent viscous liquids, while powders must be dry, flowable, and possess specific hygroscopic properties. The physicochemical requirements strictly define the minimum content of choline chloride across different concentrations (e.g., 50%, 60%, 70%, 75%). It also sets maximum limits for critical impurities and parameters such as pH value, ethylene glycol, total free amine/ammonia, ignition residue, and drying loss weight. Compliance with these specific concentration and impurity thresholds is critical for product validation. Furthermore, the standard enforces strict hygiene indicators, establishing maximum limits for heavy metals (calculated as Pb) and total arsenic (calculated as As). These safety parameters ensure that the feed additives do not pose toxicity risks to livestock.

試験方法

The standard outlines rigorous testing procedures, notably introducing ion chromatography as the arbitration method for the qualitative and quantitative determination of choline chloride content. Alternatively, a Reinecke salt gravimetric method is also specified. Additional testing methods include titration for determining ethylene glycol and total free amine/ammonia, along with standard gravimetric procedures for ignition residue, drying loss weight, and fineness. Heavy metals and total arsenic are evaluated using separate standardized turbidimetric and hydride generation methods referenced in NY/T 4689 and GB/T 13079 respectively.

よくある質問

What products are regulated under GB 7300.206-2025?

This standard applies to choline chloride feed additives in two main forms: liquid solutions (water agents) and powder formulations. The powder formulations are further categorized based on the carrier used, specifically plant-derived carriers or silica dioxide (SiO2) carriers.

Are there any updates from the previous version of GB 7300.206-2025?

The new standard introduces several key changes: it adds requirements for raw materials, includes ion chromatography as the new arbitration method for qualitative and quantitative analysis, updates precision requirements, and modifies the testing method for heavy metals. Manufacturers previously complying with the 2017 version must update their testing protocols to meet these new requirements.

How does GB 7300.206-2025 differ from ISO standards?

GB 7300.206-2025 is a mandatory Chinese national standard specifically tailored for the domestic feed additive industry. It references its own series of GB standards for hygiene and sampling (e.g., GB 13078 and GB/T 14699). Overseas manufacturers must strictly adhere to this specific GB standard rather than relying solely on ISO equivalents to ensure market access in China.

The summary above provides a high-level overview of GB 7300.206-2025. To ensure complete compliance for your feed additive products entering the Chinese market, a precise and professional translation of the full technical specifications is essential.
