赖氨酸铜络（螯）合物 — additive cross-jurisdiction identity
Derived crosswalk of how one feed additive is named and authorised across three jurisdictions. No claim of regulatory equivalence is made — pairings are anchored on the substance identity, and the verdict states where the definitions actually diverge.

Per-jurisdiction entry
- 🇨🇳 CN — 公告2045
赖氨酸铜络（螯）合物: 赖氨酸铜络（螯）合物 is listed in 表一 饲料添加剂品种目录 (category 氨基酸、氨基酸盐及其类似物 for amino acids / 矿物元素及其络（螯）合物 for chelates / 维生素及类维生素 for vitamins), scope 养殖动物 (all livestock and poultry). _(src: CN 公告2045)_ - 🇪🇺 EU — Reg 1831/2003
(EU) 2020/1378: Commission Implementing Regulation (EU) 2020/1378 of 1 October 2020 concerning the authorisation of copper chelate of lysine and glutamic acid as a feed additive for all animal species (Text with EEA relevance) _(src: EU (EU) 2020/1378)_ - 🇺🇸 AAFCO (US) — Ch.6
57.142Metal Amino Acid Chelate: Metal Amino Acid Chelate is the product resulting from the reaction of a metal ion from a soluble metal salt with amino acids with a mole ratio of one mole of metal to one to three (preferably two) moles of amino acid to form coordinate covalent bonds. _(src: AAFCO OP 2024 Ch.6, code 57.142)_
Crosswalk verdict
CN 公告2045 lists 赖氨酸铜络（螯）合物 (copper lysine chelate); EU 2020/1378 authorises copper chelate of lysine and glutamic acid for all animal species. AAFCO OP 2024 Ch.6 has no copper-lysine-specific entry; the generic Metal Amino Acid Chelate (57.142) covers metal-amino-acid chelates. Verdict: CN↔EU equivalent; AAFCO generic class only.
