HS Code for Complete fertilizer

Complete fertilizers are classified under HS code 3105.20. In the context of the Harmonized System, a "complete" fertilizer is defined as a mineral or chemical fertilizer that contains all three primary fertilizing elements: nitrogen (N), phosphorus (P), and potassium (K). Chapter 31 covers fertilizers, and heading 3105 specifically addresses fertilizers containing two or three of the fertilizing elements. Subheading 3105.20 is the precise code for those containing all three. This classification is based on the chemical composition of the product rather than its physical form (liquid, powder, or pellet). According to Note 6 to Chapter 31, the term "other fertilizers" applies only to products of a kind used as fertilizers and containing, as an essential constituent, at least one of the fertilizing elements. For 3105.20, the presence of N, P, and K must be verifiable through chemical analysis. This ensures that ternary NPK complexes are grouped together for international trade and regulatory purposes.

Products Included

• NPK complex fertilizers (e.g., 10-10-10 or 20-20-20)
• Mineral fertilizers containing N, P, and K
• Chemical fertilizers with all three primary nutrients
• Granulated complete plant foods
• Liquid NPK fertilizers for agricultural use

Common Misclassification

Complete fertilizers are often misclassified under HS code 3105.30 (diammonium phosphate) or 3105.40 (ammonium dihydrogen orthophosphate) if the importer focuses only on the nitrogen and phosphorus content and ignores the potassium. Another common error is using codes from 3102 (nitrogenous), 3103 (phosphatic), or 3104 (potassic) for a blended product. Those headings are strictly for fertilizers containing only one of the primary elements. If a fertilizer contains N, P, and K, it must be in 3105.20. Furthermore, organic fertilizers (animal or vegetable origin) are classified in 3101 and should not be confused with the mineral/chemical NPK fertilizers of 3105.20.

FAQ

What is the HS code for NPK fertilizer?

The HS code for NPK fertilizer containing all three elements is 3105.20.

What if the fertilizer only contains Nitrogen and Potassium?

If it only contains two elements, it would be classified under 3105.60 (Phosphorus and Potassium) or 3105.90 (other combinations), but not 3105.20.
