Mineral or chemical fertilizers, nitrogenous
11 declarable lines
Heading 3102 covers mineral or chemical fertilizers that are nitrogenous, such as urea, ammonium sulfate, ammonium nitrate, and sodium nitrate. The heading splits first by the specific nitrogen compound, then, for urea, by physical form or end use, and the listed lines carry a general (MFN) rate of Free.
Products in this heading
- Solid urea fertilizer
- Diesel exhaust fluid (DEF) meeting ISO 22241
- Ammonium sulfate fertilizer
- Ammonium nitrate fertilizer
- Sodium nitrate fertilizer
- Mixtures of urea and ammonium nitrate in solution
- Calcium nitrate and ammonium nitrate double salts
- Ammonium nitrate mixed with calcium carbonate
How to choose the right subheading
- Identify the chemical compound: urea, ammonium sulfate, ammonium nitrate, sodium nitrate, or a mixture.
- For urea, decide whether it is solid or in aqueous solution.
- For liquid urea, check whether it meets ISO 22241 as diesel exhaust fluid.
- For ammonium sulfate lines, decide whether the good is plain ammonium sulfate or a double salt or mixture.
- For the residual subheading, confirm the good is not named in an earlier subheading.
Often confused with
- Heading 3103Phosphatic fertilizer such as superphosphate
Nitrogen is not the fertilizing element that governs classification.
- Heading 3104Potassic fertilizer such as potassium chloride
These are classified as potassic fertilizers, not nitrogenous.
- Heading 3105NPK blended fertilizer containing nitrogen, phosphorus and potassium
Goods with two or three fertilizing elements go to heading 3105.
- Heading 3105Small retail packages of fertilizer of a gross weight not over 10 kg
Chapter 31 goods in tablets or packages of 10 kg or less fall in 3105.
