Import Tips

• Provide Certificate of Analysis (CoA) confirming USP grade purity >98% and identity via HPLC to avoid reclassification as non-pharmaceutical chemical

• Include FDA Drug Master File (DMF) reference and end-use statement specifying pharmaceutical manufacturing to qualify for drug tariff treatment

• Ensure proper hazardous material declaration (UN 2811) as toxic substance; common pitfall is inadequate stability data for shelf-life claims
