EN — What is GB/T 31216-2014? China's voluntary national standard for industrially produced complete dog food (excluding prescription diets). 2014.09.03 Posted 2015.03.08 Implemented. It sets minima (or maxima) for nutrients on a dry-matter basis, by life stage (juvenile / pregnant / lactating dog food vs adult dog food).
Key physical & chemical indicators (dry-matter basis):
Crude protein ≥22.0 ≥18.0(juvenile/pregnant/lactating vs adult)Crude fat ≥8.0 ≥5.0Calcium ≥1.0 ≥0.6Total phosphorus ≥ 0.8 ≥0.5- Water-soluble chloride (as Cl⁻): ≥0.45% (juvenile/pregnant/lactating) / ≥0.09% (adult)
Lysine ≥0.77 ≥0.63
Moisture classes: dry <14.0%, semi-moist 14.0–60.0%, wet ≥60.0%. Hygiene (88% dry-matter basis): fluorine ≤150 mg/kg, cadmium ≤2 mg/kg, lead ≤5 mg/kg, total arsenic ≤10 mg/kg (or ≤2 mg/kg), aflatoxin B₁ ≤10 µg/kg, total bacteria <1×10⁴ CFU/g, Salmonella not found in 25 g. Note: calcium and phosphorus carry minima only — no upper limits are set.
中文 — GB/T 31216-2014 是什么？ 中国全价宠物食品（狗粮）推荐性国家标准（不含处方类食品）。2014.09.03 Posted 2015.03.08 Implemented。按干物质基础、不同生活阶段（动物籽/怀孕乳母狗粮 vs 成年狗粮）设最低（或最高）指标。
主要理化指标（干物质基础）：Crude protein ≥22.0 ≥18.0、Crude fat ≥8.0 ≥5.0、Calcium ≥1.0 ≥0.6、Total phosphorus ≥ 0.8 ≥0.5、水溶性氯（以 Cl⁻计）≥0.45%/≥0.09%、Lysine ≥0.77 ≥0.63。水分分类：干性 <14.0%、半湿 14.0–60.0%、湿性 ≥60.0%。卫生指标（按 88% 干物质）：氟 ≤150 mg/kg、锰 ≤2 mg/kg、铅 ≤5 mg/kg、总神 ≤10 mg/kg、黄曲霉毒素 B₁ ≤10 µg/kg。钙、磷仅有下限、无上限。
