二丁基羟基甲苯（BHT） — additive cross-jurisdiction identity
Derived crosswalk of how one feed additive is named and authorised across jurisdictions. No claim of regulatory equivalence is made — pairings are anchored on the substance identity, and the verdict states where the definitions actually diverge.

Authorised in the EU feed additives register (first-hand-derived parse of the EU Food & Feed Information Portal register).

This ingredient is approved for use as an antioxidant in an amount not to exceed 0.02% (butylated hydroxyanisole plus butylated hydroxytoluene) of the fat or oil content of the complete feed for livestock species. It shall be labelled with the following statement: "This ingredient is approved for use as an antioxidant in an amount not to exceed 0.02% (butylated hydroxyanisole plus butylated hydroxytoluene) of the fat or oil content of the complete feed for livestock species." It shall be labelled with a guarantee for minimum percent butylated hydroxytoluene. | Canadian Feed Ingredients Table (CFIT), inspection.canada.ca; SOR/2024-132; feed additive listed under Part 1 > Class 6.

Crosswalk verdict
CN 公告2045 lists 二丁基羟基甲苯（BHT） (scope 养殖动物). FDA EAFUS lists BUTYLATED HYDROXYTOLUENE (CAS 128-37-0, used for ANTIOXIDANT) as a food substance. AAFCO OP 2024 Ch.6 has no stand-alone entry for this substance (honest gap). Verdict: CN↔US diverge in chemical form or regulatory framing; the pairing is the closest available US analogue, not a confirmed regulatory equivalence (EU filled from the EU Feed Additives Register (FFP parsed dataset)).
