Import Tips

Include USP certificate and purity assay (>90% carrageenan) to prevent reclassification as a pharmaceutical under Chapter 30

Ensure DMF (Drug Master File) if for pharma use, and align with FDA import alerts on seaweed contaminants

Declare exact sulfate content, as high levels may trigger additional testing or duties under environmental regs
