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
