Manganese methionine chelate has no entry in the EU feed additives register; the EU authorises the hydroxy analogue of methionine chelate for manganese (E-number 3b510), which is a different substance.

FDA EAFUS contains no corresponding entry for Manganese methionine chelate (search for 'MANGANESE METHIONINE' returned no 21 CFR listing); recorded as an honest no_confirmed_equivalent — not fabricated. AAFCO OP 2024 Ch.6 defines Metal Amino Acid Chelate (code 57.142). 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).\n\n\n## Species & use scope (适用范围)\n\nCross-jurisdiction species / use-scope dimension surfaced from each jurisdiction's retrieved source.
