Mineral or chemical fertilizers, phosphatic
3 declarable lines
Heading 3103 covers mineral or chemical fertilizers that are phosphatic. It is split into one line for superphosphates containing 35% or more of diphosphorous pentaoxide (P2O5), one line for other superphosphates, and a residual line for other phosphatic fertilizers. All three lines carry a general (MFN) rate of Free.
Products in this heading
- Superphosphate fertilizer containing 35% or more of P2O5
- Superphosphate fertilizer containing less than 35% of P2O5
- Triple superphosphate fertilizer
- Single superphosphate fertilizer
- Granulated phosphatic fertilizer
- Phosphatic fertilizer for direct soil application
- Basic slag fertilizer
- Calcined phosphate fertilizer
How to choose the right subheading
- Decide whether the product is a superphosphate or another phosphatic fertilizer.
- For superphosphate, check the P2O5 content by weight: 35% or more goes to 3103.11.00.00, and less than 35% goes to 3103.19.00.00.
- If the product is phosphatic but not a superphosphate, use the residual line 3103.90.01.00.
- Check whether the product also contains nitrogen or potassium; fertilizers with two or three fertilizing elements are classified in heading 3105.
- Check the form and package type; tablet forms and small retail packages of chapter 31 goods can be classified in heading 3105.
Often confused with
- Heading 3102Nitrogenous fertilizer such as urea
Heading 3103 covers phosphatic fertilizers, not nitrogenous fertilizers.
- Heading 3104Potassic fertilizer such as potassium chloride
Potassium is a potassic fertilizing element, so it falls under heading 3104.
- Heading 3105NPK compound fertilizer
Fertilizers with two or three of nitrogen, phosphorus and potassium are classified in heading 3105.
- Heading 3105Monoammonium phosphate or diammonium phosphate fertilizer
These ammonium phosphates are specifically classified in heading 3105, not as plain phosphatic fertilizers in 3103.
- Heading 2510Natural phosphate rock
Natural calcium phosphates are classified as mineral products in heading 2510, not as manufactured phosphatic fertilizer.
