Import Tips
• Verify cocoons are suitable for reeling by confirming intact pupa removal capability; damaged ones may shift to waste categories
• Obtain phytosanitary certificates proving fumigation to prevent insect pests, a common CBP requirement for agricultural imports
• Declare exact weight excluding pupae remnants to avoid discrepancies in duty calculations
