Subheadings
Products classified under HTS 3104.20.00
Muriate of Potash Fertilizer
Muriate of potash, chemically known as potassium chloride (KCl), is a widely used potassic fertilizer providing essential potassium for plant growth. It falls under HTS 3104.20.00 as it matches the legal definition of potassium chloride in Chapter 31 for mineral fertilizers. Typically available in granular form for agricultural application.
Granular Potassium Chloride 60% K2O Fertilizer
This granular fertilizer contains 60% potassium oxide equivalent from potassium chloride, designed for soil application in crops like potatoes and tomatoes. Classified under HTS 3104.20.00 per Chapter 31 note for potassic mineral fertilizers. The chloride content helps with plant nutrition but requires soil testing for saline-sensitive crops.
Water-Soluble Potassium Chloride Fertilizer
A highly soluble form of potassium chloride used in fertigation systems for greenhouse crops and hydroponics. It qualifies under HTS 3104.20.00 as potassium chloride per Chapter 31 definitions for potassic fertilizers. Dissolves quickly for precise nutrient delivery through irrigation.
Crop-Specific Potassium Chloride for Tobacco
Specialty potassium chloride formulation optimized for tobacco crops to improve leaf quality and disease resistance. Falls under HTS 3104.20.00 as it is chemically potassium chloride for agricultural use per Chapter 31. Granules sized for tobacco field application.
Bulk Potassium Chloride for Blending Operations
Bulk potassium chloride imported for fertilizer blending plants to create custom NPK formulations. Classified under HTS 3104.20.00 per Chapter 31 as pure potassic fertilizer not in retail form. Ships in 50-ton containers for industrial agricultural mixing.
Anti-Caking Potassium Chloride Fertilizer
Potassium chloride treated with anti-caking agents for free-flowing application in humid climates. Still classified as potassium chloride under HTS 3104.20.00 since additives don't change chemical identity per Chapter 31. Ideal for tropical agriculture.
High-Purity Agricultural Potassium Chloride
Premium potassium chloride with 99%+ purity for organic farming and high-value crops. Meets HTS 3104.20.00 criteria as potassium chloride fertilizer per Chapter 31 definitions. Low impurity levels prevent soil contamination.
Potassium Chloride for Drip Irrigation
Fine powder potassium chloride specifically sized for drip irrigation systems in orchards and vineyards. Falls under HTS 3104.20.00 as potassic mineral fertilizer per Chapter 31. Dissolves completely without clogging emitters.
Winterizer Potassium Chloride Fertilizer
Late-season potassium chloride application to enhance plant hardiness before winter dormancy. Classified under HTS 3104.20.00 as potassium chloride fertilizer. Coarse granules for deep root penetration.
Certified Organic Potassium Chloride Fertilizer
OMRI-listed potassium chloride meeting organic farming standards through mining and minimal processing. Qualifies under HTS 3104.20.00 as potassic fertilizer per Chapter 31. Essential for certified organic potassium nutrition.
