CN function claim 3 categories

China's pet feed label rules (MOA Announcement No. 20, 2018, Annex 3 宠物饲料标签规定, Article 20) recognize three claim types. (1) Ingredient claims (成分声称): 'XX配方' requires the named ingredient at ≥26% of total product weight; '含XX配方' ≥14%; '含XX' ≥4%; for combination claims at least one ingredient must meet the main threshold and each other ≥3%, listed in descending weight order. '添加XX' may be used below 4% if the addition confers a specific attribute. '无XX/不含XX' claims are limited to feed ingredients/additives, except gluten which may be claimed '无麸质' at ≤20 mg/kg. (2) Characteristic claims (特性声称): '天然/天然粮', '新鲜', '低脂肪' (dog: fat ≤9%/7%/4% for dry/semi-moist/wet; cat: ≤10%/8%/5%) and '低能量' (dog ≤1296/1045/376 kJ ME/100g; cat ≤1359/1108/397 kJ ME/100g by moisture class). Comparative claims ('高/低') must exceed 15% versus the company's own reference product. (3) Function claims (功能声称): allowed for maintaining or enhancing growth, development, physiological function or health; prevention claims (预防) are permitted only for non-disease issues such as hairballs and tartar. Claims of preventing or treating pet diseases are prohibited. All claims require substantiation (publications, formula data, or test reports); 'new product' claims may appear for at most 18 months.
