HS Code 3105Fertilizers; mineral or chemical, containing 2 or 3 of the elements nitrogen, phosphorus, potassium; other fertilisers; goods of chapter 31 in tablets or packages of gross weight not exceeding 10kg

What HS code 3105 covers

The three plant nutrients are nitrogen, phosphorus and potassium. A product that has two or three of them usually belongs here. Traders call these NPK fertilizers or compound fertilizers.

The heading also takes other fertilizers of this group that fit nowhere else. So the pack size can decide the code, not only the recipe.

If you are new to the group, the Chapter 31 fertilizers page shows how all the headings fit together.

Six-digit codes under heading 3105

Each six-digit subheading narrows the heading down. Pick the most specific line that fits your product. Use the last line only when no other line fits. If you are unsure, the HS code classifier can help with HS classification.

• 310510: fertilizers in tablets or similar forms, or in small packs of 10kg gross weight or less. This is the small-pack code.
• This is the usual answer for NPK.
• 310530: diammonium phosphate, known as DAP.
• 310540: monoammonium phosphate, known as MAP, and blends of MAP with DAP.
• 310551: fertilizers with two nutrients that contain nitrates and phosphates.
• 310559: fertilizers with nitrogen and phosphorus that are not the nitrate and phosphate type.
• 310590: other fertilizers in this heading that no line above names.

3105 vs 3102, 3103 and 3104: choosing the right heading

The nearby headings split by nutrient. Heading 3102 is for nitrogen fertilizers. Heading 3103 is for phosphate fertilizers. Heading 3104 is for potash fertilizers. Each one holds a product with a single main nutrient.

Heading 3105 starts where a product has two or three of these nutrients. That is why DAP and MAP sit here, since each has both nitrogen and phosphorus.

Heading 3101 is different. It is for fertilizers of animal or vegetable origin, with or without mixing or chemical treatment.

Check the pack size too. A fertilizer in a package of 10kg or less can fall under 310510, even when its nutrients would point to another heading in this chapter. Read the exact wording of the code before you file.
