Import Tips & Compliance

• Verify nitrogen content (e.g

• 32-34%) via lab analysis to confirm classification under 3102.80; pure urea solutions may shift to 3102.10

• Include safety data sheets (SDS) documenting aqueous/ammoniacal composition and non-explosive formulation for customs clearance

• Ensure DOT-compliant packaging for liquid fertilizers to avoid delays; check for fertilizer registration requirements in destination country
