HS Code for Sodium nitrate

Sodium nitrate is classified under HS code 2834.29. This heading covers nitrites and nitrates, and the subheading 2834.29 is a residual category for nitrates other than potassium nitrate. Sodium nitrate (NaNO3) is a white solid that is highly soluble in water and acts as a strong oxidizing agent. Its classification is unique due to its dual role as an industrial chemical and a fertilizer. According to the Chapter Notes for Chapter 31 (Fertilizers), sodium nitrate is one of the few substances that can be classified as a fertilizer even if it is chemically pure, provided it is intended for such use. Specifically, 3102.50 is the code for sodium nitrate used as a fertilizer. However, when sodium nitrate is intended for industrial applications—such as in the manufacture of glass, explosives, enamels, or as a food preservative—it is classified under 2834.29. This industrial classification applies to technical, reagent, and pharmaceutical grades. The distinction often depends on the packaging and the documentation accompanying the shipment. For instance, sodium nitrate sold in bulk for agricultural use is almost always 3102.50, while high-purity crystals sold for laboratory use or glass production are 2834.29. It is also used in heat storage for concentrated solar power plants. The classification is governed by the intended use and the purity of the product, following the legal notes of Section VI. It is also important to distinguish sodium nitrate from sodium nitrite (NaNO2), which is classified under 2834.10. Proper documentation of the product's grade and intended application is essential for correct customs entry.

Common Misclassification

The most common misclassification is between 2834.29 and 3102.50 (fertilizer grade). It is also frequently confused with 2834.10 (sodium nitrite) or 2834.21 (potassium nitrate). In some cases, it may be confused with 3824.99 if it is part of a specialized explosive precursor blend.

FAQ
