HS Code for PK fertilizer

PK fertilizers are classified under HS code 3105.60. These are mineral or chemical fertilizers that contain two primary fertilizing elements: phosphorus (P) and potassium (K). Classification is determined by Chapter 31, which covers fertilizers. Heading 3105 specifically applies to fertilizers containing two or three of the fertilizing elements nitrogen, phosphorus, and potassium. Subheading 3105.60 is the specific designation for fertilizers that contain phosphorus and potassium but do not contain nitrogen. This classification applies whether the product is in a solid form (tablets, granules) or in packages with a gross weight exceeding 10 kg. If the product is in smaller packages for retail sale, it may still fall under 3105.10, but 3105.60 is the standard for bulk agricultural PK blends.

Products Included

• Potassium phosphate fertilizers
• Mixtures of superphosphates and potassium chloride
• PK 0-20-20 granular fertilizer
• Liquid PK 0-10-15 fertilizer blends
• Mono-potassium phosphate (MKP) used as fertilizer

Common Misclassification

PK fertilizers are often misclassified under 3105.20, which is for NPK fertilizers. If a fertilizer contains even a small amount of nitrogen, it cannot be classified in 3105.60. They are also sometimes confused with 3103 (phosphatic fertilizers only) or 3104 (potassic fertilizers only). To qualify for 3105.60, the product must be a mixture of both elements. Furthermore, if the product is a separate chemically defined compound of high purity not intended for use as a fertilizer, it might be classified in Chapter 28, though most agricultural grades stay in Chapter 31.
