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
| 法域 | 名称 / 编号 | 状态 / 描述 | 来源 |
|---|---|---|---|
| 🇨🇳 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). | CN 公告2045 |
| 🇪🇺 EU | Feed Additives Register 3b415 | Copper chelate of lysine and glutamic acid — functional category 3 b. Authorised in the EU feed additives register (first-hand-derived parse of the EU Food & Feed Information Portal register). Cross-jurisdiction note: this EU authorisation is quoted from the register and is not asserted to be equivalent to the CN 公告 2045 / FDA EAFUS entries (definitions, chemical form, or conditions of use may differ). EU entry is the lysine-and-glutamic-acid chelate (not a pure lysine chelate). | EU Food & Feed Information Portal feed-additives register; parsed dataset pdf-parsed/eu_feed_additives_2023_1813.json, e_number 3b415 |
| 🇺🇸 AAFCO (US) | Ch.6 57.142 Metal 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. | AAFCO OP 2024 Ch.6, code 57.142 |
| 🇨🇦 CA | Feeds Regs 2024 (CFIT) | Copper lysine complex (or copper lysine sulfate) — is the product resulting from complexing a soluble copper salt (that is, copper sulfate) with the specific amino acid lysine. It shall be labelled with guarantees for minimum percent copper, and minimum percent bound copper. | Canadian Feed Ingredients Table (CFIT), inspection.canada.ca; SOR/2024-132; feed additive listed under Part 2 > Class 5. Nutritional ingredients > 5.3 Minerals |
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.
