Import Tips
• Provide biotech origin documentation (e.g
• GMO status if recombinant) to comply with USDA APHIS biotech regulations
• Label shipments with UN number for biological substances if applicable, and include stability data to prevent inspection delays
• Verify enzyme specificity via lot-specific assays, as CBP may test for correct classification against generic enzymes
