Research this identityContinue the compliance check
1. Confirm identity
Match the supplier specification, CAS/EC identifiers and composition to this official label name. Similar wording is not proof of chemical equivalence.
2. Review restrictions
Check every exact Annex record shown above, plus CMR, nanomaterial, SCCS and later-amendment requirements that may apply.
3. Verify the formula
Evaluate concentration, product type, purity, warnings, claims and each target market before making a compliance decision.
