Import Tips
• Include enzyme activity unit declarations certified by ISO-accredited labs to support valuation and classification claims
• Avoid bulk packaging over 25kg without secondary containment, as CBP flags large biotech shipments for biosafety review
• Cross-check against Chapter 30 exclusions by confirming it's not a blood fraction or therapeutic prep
