乙氧基喹啉 — 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.

Per-jurisdiction entry
- 🇨🇳 CN — 公告2045
乙氧基喹啉: 乙氧基喹啉 is listed in 表一 饲料添加剂品种目录 (category 抗氧化剂); scope 养殖动物. _(src: CN 公告2045)_ - 🇪🇺 EU — Feed Additives Register: No current EU authorisation entry for this substance was found in the EU feed additives register (EU Food & Feed Information Portal; parsed dataset pdf-parsed/eu_feed_additives_2023_1813.json). Ethoxyquin (CAS 91-53-2) has no entry in the EU feed additives register; its use as a feed additive was withdrawn in the EU. Do not fabricate an EU entry. _(src: EU Food & Feed Information Portal feed-additives register; parsed dataset pdf-parsed/eu_feed_additives_2023_1813.json — no matching authorisation; honest gap)_
- 🇺🇸 FDA (US) — EAFUS
91-53-2: ETHOXYQUIN listed for ANTIOXIDANT, 21 CFR 73.275 where applicable; CAS 91-53-2. _(src: FDA EAFUS, CAS 91-53-2)_ - 🇺🇸 AAFCO (US) — Ch.6: No stand-alone AAFCO OP 2024 Ch.6 entry for this substance. AAFCO defines substances only where a corresponding feed ingredient is listed; where absent, the cell is an honest gap, not a claim of non-existence. _(src: AAFCO OP 2024 Ch.6 — gap)_
- 🇨🇦 CA — Feeds Regs 2024 (CFIT): Ethoxyquin — is 1, 2-dihydro-6 ethoxy- 2, 2, 4-tri-methylquinoline, generally expressed as C14H19NO, and having the CAS# 91-53-2. This ingredient is approved for use as an antioxidant in an amount not to exceed 0.015% of the total diet 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 0.015% of the total diet for livestock species." It shall be labelled with a guarantee for minimum percent ethoxyquin. _(src: Canadian Feed Ingredients Table (CFIT), inspection.canada.ca; SOR/2024-132; feed additive listed under Part 1 > Class 6. Non-nutritive ingredients > 6.1 Preservatives, antioxidants, and stabilizers)_
Crosswalk verdict
CN 公告2045 lists 乙氧基喹啉 (scope 养殖动物). FDA EAFUS lists ETHOXYQUIN (CAS 91-53-2, used for ANTIOXIDANT, 21 CFR 73.275) 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 noted as honest gap).
