Import Tips
• Verify USP certification and provide Certificate of Analysis (CoA) to confirm purity >99% for pharmaceutical use and avoid reclassification
• Include lab test results showing it meets aminoacetic acid specs; common pitfall is mislabeling as a salt leading to different headings
• Check FDA prior notice requirements for food/pharma additives; bulk packaging must specify 'not for direct retail sale'
