二氧化钛 — 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.

Substance anchor: 二氧化钛 (Titanium dioxide)

Per-jurisdiction entry

🇨🇳 CN — 公告2045 二氧化钛: 二氧化钛 is listed in 表一饲料添加剂品种目录 (category 着色剂); scope 宠物. _(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). Titanium dioxide (CAS 13463-67-7, E 171) has no entry in the EU feed additives register; its authorisation as a feed additive was withdrawn in the EU.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 13463-67-7: TITANIUM DIOXIDE listed for ANTICAKING AGENT OR FREE-FLOW AGENT, 21 CFR 73.1575 where applicable; CAS 13463-67-7. _(src: FDA EAFUS, CAS 13463-67-7)_
🇺🇸 AAFCO (US) — Ch.6 87.146 Titanium Dioxide: is synthetically prepared TiO2, free from admixture with other substances. _(src: AAFCO OP 2024 Ch.6, code 87.146)_

🇨🇦 CA — honest gap: not listed in CFIT as a feed additive. _(src: Canadian Feed Ingredients Table (CFIT), inspection.canada.ca; SOR/2024-132)_

Crosswalk verdict

CN 公告2045 lists 二氧化钛 (scope 宠物). FDA EAFUS lists TITANIUM DIOXIDE (CAS 13463-67-7, used for ANTICAKING AGENT OR FREE-FLOW AGENT, 21 CFR 73.1575) as a food substance. AAFCO OP 2024 Ch.6 defines Titanium Dioxide (code 87.146). 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).

Species & use scope (适用范围)

Cross-jurisdiction species / use-scope dimension surfaced from each jurisdiction's retrieved source. CN 适用范围 is quoted verbatim from the 公告2045 饲料添加剂品种目录; EU target-species and FDA use-class reflect only what is already present in the topic's own cells (no new source fetches).

🇨🇳 CN (公告2045 适用范围): 宠物 _(src: 农业部公告第2045号饲料添加剂品种目录, 适用范围)_
🇪🇺 EU (target species): honest gap — target-species / conditions of use not present in the currently retrieved EU source (conditions_of_use deferred). _(src: EU Feed Additives Register — gap)_
🇺🇸 FDA (EAFUS use class): ANTICAKING AGENT OR FREE-FLOW AGENT _(src: FDA EAFUS, re-surfaced from topic FDA cell)_
