Import Tips

Provide Safety Data Sheets (SDS) and confirm REACH compliance for EU markets or TSCA registration for US

Verify purity levels (>98%) as impurities may affect classification; include certificate of analysis

Check for flame retardant restrictions under Stockholm Convention; avoid common pitfalls like mislabeling as general brominated hydrocarbon
