Import Tips
• Obtain EPA registration number and ensure product labeling complies with FIFRA for pesticide imports
• Provide Certificate of Analysis confirming purity as a chemically defined aromatic carboxylic acid derivative
• Verify not excluded under chapter notes (e.g
• not a salt or ester classified elsewhere); common pitfall is confusing with formulations
