Import Tips & Compliance
• Verify purity levels and ensure the product meets potassic fertilizer definitions excluding animal blood or chemically defined compounds per Chapter 31 notes
• Provide certificates of analysis confirming K2O content for customs valuation and classification
• Avoid common pitfalls by ensuring bulk packaging to prevent reclassification under retail heading 3105

Potassium Sulfate Fertilizer (Sulfate of Potash)
Crystalline potassium sulfate (K2SO4) fertilizer, also called sulfate of potash, supplies potassium and sulfur to crops without chloride. Classified under HTS 3104.90.0100 as 'other' potassic fertilizers not enumerated in prior headings or retail packaged.
Mono Potassium Phosphate (MKP) Fertilizer
Water-soluble mono potassium phosphate (KH2PO4) provides potassium and phosphorus for fertigation systems. It qualifies under HTS 3104.90.0100 as an 'other' potassic fertilizer since phosphorus content doesn't trigger superphosphate classification in 3103.
Potassium Nitrate Fertilizer
Crystalline potassium nitrate (KNO3) delivers potassium and nitrogen for greenhouse and hydroponic production. Falls under HTS 3104.90.0100 as other potassic fertilizers not specifically covered by ammonium nitrate mixtures in heading 3102.
Potassium Magnesium Sulfate Fertilizer
Langbeinite ore-based fertilizer containing potassium, magnesium, and sulfur for organic farming. Classified HTS 3104.90.0100 as mineral potassic not fitting specific salt descriptions or phosphatic categories.
Sulpomag Potassium-Magnesium Fertilizer
Granulated sulpomag (K2SO4·2MgSO4) provides potassium, magnesium, and sulfur for crop nutrition. HTS 3104.90.0100 covers this as other potassic mineral fertilizer not matching enumerated chemical salts.
