Import Tips
• Obtain FDA and EPA approvals for medical-grade imports; provide GMP certificates to avoid holds on pharmaceutical precursor chemicals
• Document as 'not for retail sale' to distinguish from Chapter 29 exclusion (k) for certain packings
• Test for impurities; Chapter 29 note (a) allows minor impurities but requires analytical reports for customs verification
