L-半胱氨酸盐酸盐 — 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.

Crosswalk verdict
CN 公告2045 lists L-半胱氨酸盐酸盐 (scope 犬、猫). FDA EAFUS lists L-CYSTEINE MONOHYDROCHLORIDE (CAS 52-89-1, used for DOUGH STRENGTHENER) 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)).
