硝酸硫胺（维生素 B1） — additive cross-jurisdiction identity

硝酸硫胺（维生素 B1） — 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 硝酸硫胺（维生素 B1）: 硝酸硫胺（维生素 B1） is listed in 表一 饲料添加剂品种目录 (category 维生素及类维生素); scope 养殖动物. _(src: CN 公告2045)_
• 🇪🇺 EU — Feed Additives Register 3a821: Thiamine mononitrate or Vitamin B1 — functional category 3 a. 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). _(src: EU Food & Feed Information Portal feed-additives register; parsed dataset pdf-parsed/eu_feed_additives_2023_1813.json, e_number 3a821)_

• 🇨🇦 CA — Feeds Regs 2024 (CFIT): Thiamine mononitrate — is the mononitrate of thiamine, generally expressed as C12H17N5O4S, and having the CAS# 532-43-4. It shall be labelled with guarantees for minimum milligrams of thiamine mononitrate per kilogram, and minimum milligrams of thiamine hydrochloride equivalent per kilogram. _(src: Canadian Feed Ingredients Table (CFIT), inspection.canada.ca; SOR/2024-132; feed additive listed under Part 1 > Class 5.

Crosswalk verdict

CN 公告2045 lists 硝酸硫胺（维生素 B1） (scope 养殖动物). FDA EAFUS lists THIAMINE MONONITRATE (CAS 532-43-4, used for NUTRIENT SUPPLEMENT) as a food substance. AAFCO OP 2024 Ch.6 defines Thiamine mononitrate Vitamin B2 (code 90.25). 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)).

Recall mentions

_Derived from the in-repo recall datasets (RASFF 257 notifications, FDA CVM 58 pet-food recalls, FDA enforcement 186 general-food recalls). These are mentions of the additive name in recall records — mention ≠ causation: a recall citing the additive by name does not mean the additive itself was the hazard (the FDA enforcement set spans human food too). Each line is a verbatim substring of the cited recall source._
