Import Tips

• Obtain EPA registration and import alerts for pesticide active ingredients; provide technical data sheets confirming glufosinate content

• Ensure proper labeling as hazardous material (UN 2815) with phosphonic acid group declarations for DOT compliance

• Verify purity >95% to avoid reclassification; common pitfall is contamination leading to mixture headings
