Import Tips

Label as USP-grade with CAS number (51-05-8); include pharmacopeia certificates to confirm drug status

Document ester-salt structure to prevent reclassification; common issue is declaring as base form only

For frozen shipments, note stabilizer additions per Chapter 29(g) to avoid duty disputes
