Complete vs complementary pet food: how the EU and China define it
"Complete" is the most important word on a pet-food label, because it tells the buyer whether the product can be the sole diet or must be fed alongside something else. Two jurisdictions define the boundary differently.
EU: complete vs complementary (Reg 767/2009, Article 3)
- "complete feed" = compound feed which, by reason of its composition, is sufficient for a daily ration.
- "complementary feed" = compound feed which has a high content of certain substances but which, by reason of its composition, is sufficient for a daily ration only if used in combination with other feed.
Under this split, a complementary feed wrongly labelled "complete" is a labelling violation.
China: "complete pet food" as a national standard
China does not use the complementary/complete pair as a statutory definition in the same way; instead it sets national standards for "complete pet food" (配合饲料):
- GB/T 31216-2014 — complete dog food. Minimum crude protein ≥18.0 % (adult) / ≥22.0 % (juvenile), crude fat ≥5.0 / ≥8.0, calcium ≥0.6 / ≥1.0, total phosphorus ≥0.5 / ≥0.8 (% DM); plus water-soluble chloride and lysine minimums.
- GB/T 31217-2014 — complete cat food. Minimum crude protein ≥25.0 / ≥28.0, crude fat ≥9.0, calcium ≥0.6 / ≥1.0, total phosphorus ≥0.5 / ≥0.8 (% DM); and a cat-specific taurine minimum of ≥0.1 % (dry food) / ≥0.2 % (wet food).
A product sold in China as "complete pet food" is expected to meet these GB/T nutrient floors. China's framework therefore defines the complete end of the spectrum by nutrient standard, rather than by an explicit "complementary" statutory counterpart.
The practical takeaway
- In the EU, the complete/complementary distinction is a labelling-claim definition (Reg 767/2009 Art. 3) enforced at the label level.
- In China, "complete pet food" is anchored to nutrient national standards (GB/T 31216/31217), with the taurine split by moisture form unique to that standard.
Both systems converge on the same consumer promise — a "complete" product is safe as the sole diet — but they police it through different legal instruments.
