Import Tips
• Verify P2O5 content through lab analysis to confirm classification under 3103.11.00.00 (≥35%) vs lower grades in 3103.10
• Obtain fertilizer registration certificates from USDA/APHIS and ensure proper labeling of nutrient content per EPA FIFRA regulations
• Avoid common pitfalls like misdeclaring as blended fertilizer, which could shift to 3105 if packaged for retail
