HS Code for NP fertilizer

NP fertilizers are classified under HS code 3105.59. Chapter 31 of the Harmonized System covers fertilizers, and heading 3105 is specifically for mineral or chemical fertilizers containing two or three of the fertilizing elements nitrogen, phosphorus, and potassium. Subheading 3105.59 is designated for fertilizers containing the two elements nitrogen and phosphorus, but which are not specifically mentioned in other subheadings like 3105.30 (diammonium phosphate) or 3105.40 (monoammonium phosphate). This classification is driven by the chemical analysis of the product, ensuring it contains significant amounts of both N and P while lacking K (potassium). The "other than nitrates and phosphates" part of the description refers to specific chemical structures that might be classified elsewhere. For a product to fall under 3105.59, it must be a mixture or a chemically produced compound intended for use as a fertilizer. This code is essential for tracking the trade of specialized nutrient blends used in agriculture to address specific soil deficiencies where potassium is already abundant or not required. The classification follows GRI 1 and 6, focusing on the chemical constituents and the specific exclusions mentioned in the legal notes of Chapter 31.

Products Included

• NP 20-20-0 fertilizer blends
• Ammonium polyphosphate solutions
• Nitrophosphates (not elsewhere specified)
• Chemically combined Nitrogen-Phosphorus compounds

Common Misclassification

NP fertilizers are often misclassified under 3105.30 (DAP) or 3105.40 (MAP) if the specific chemical identity is not clearly defined. They are also confused with 3105.20 (NPK) if trace amounts of potassium are present, or 3102/3103 if the product is mistakenly thought to contain only one primary nutrient.

FAQ

What is the HS code for NP fertilizer?

The HS code for NP fertilizer (containing nitrogen and phosphorus) is 3105.59.

Can a fertilizer with 1% potassium be classified as NP?

Generally, if potassium is present in a quantity that provides nutritional value, it must be classified as NPK under 3105.20. NP classification is for products essentially lacking potassium.
