Import Tips

• Provide EPA registration documents and purity certificates (typically >95%) to verify technical grade status and avoid reclassification as formulated product

• Include Material Safety Data Sheets (MSDS) detailing aromatic amide structure to confirm classification under Chapter 29 organic compounds

• Ensure packaging meets UN hazardous materials standards for pesticide imports to prevent customs delays
