HS Code for CAN fertilizer

Calcium Ammonium Nitrate (CAN) fertilizer is classified under HS code 3102.40. This classification is determined by the Harmonized System's Chapter 31, which covers mineral or chemical fertilizers. Specifically, 3102.40 is reserved for mixtures of ammonium nitrate with calcium carbonate or other inorganic non-fertilizing substances. The classification logic hinges on the fact that CAN is a nitrogenous fertilizer where the ammonium nitrate is stabilized by an inert filler, typically limestone or dolomite. This stabilization is crucial for safety, as pure ammonium nitrate is highly volatile. To qualify for this code, the product must be intended for agricultural use and the nitrogen content must be derived from the ammonium nitrate component. The presence of calcium carbonate serves as a pH neutralizer and a safety diluent, distinguishing it from pure nitrogen fertilizers or complex NPK blends.

Common Misclassification

CAN fertilizer is frequently misclassified under HS code 3102.30, which is strictly for pure ammonium nitrate, whether or not in aqueous solution. Another common error is using HS code 3105.20 for NPK fertilizers; however, CAN does not contain significant phosphorus or potassium. If the mixture contains other fertilizing elements like sulfur in significant quantities, it might be pushed into 3105.90, but standard CAN remains firmly in 3102.40.

FAQ

What is the HS code for CAN fertilizer?

The HS code for Calcium Ammonium Nitrate (CAN) fertilizer is 3102.40.

Does CAN fertilizer require special hazardous material documentation?

While CAN is classified under 3102.40 for trade, it is often subject to specific transport regulations (such as UN 2067) because it contains ammonium nitrate, though it is significantly less hazardous than pure 3102.30 products.
