Import Tips
• Use ISBP documentation standards for chemical purity assays to support valuation and classification claims
• Ensure no color/odor additions render it suitable for specific use, per note (g), to avoid reclassification
• For drum imports, verify packaging doesn't constitute 'retail sale' packing that shifts to other chapters
