Import Tips

Verify purity certificate (≥98%) to confirm chemical definition per Chapter 29 note (a); impurities must not alter classification

Include SDS and REACH compliance docs for EU-origin shipments to avoid customs holds on toxic phenol derivatives

Avoid bulk packaging over 25kg without stabilizers, as anti-dusting agents are allowed only if not rendering product use-specific (note g)
