Import Tips
• Submit certificate of analysis showing pronamide content exceeds 50% to qualify as named chemical rather than 'other' pesticide preparation
• Declare as 'technical material for formulation' on commercial invoice to distinguish from end-use products under Chapter 38
• Verify no retail packaging or labeling that would trigger consumer product classification
