Import Tips & Compliance

• Provide lot-specific CoA confirming >99% purity to maintain specific compound status

• Label with GHS hazard pictograms for skin/eye irritant and specific target organ toxicity

• Avoid common pitfall of declaring as 'bromine compound' generically; specify exact CAS 3194-57-8
