HS Code for Chile saltpeter

Chile saltpeter, chemically known as sodium nitrate, is classified under HS code 310250 because it is primarily utilized as a nitrogenous mineral or chemical fertilizer. Chapter 31 of the Harmonized System is dedicated to fertilizers, which are substances used to provide nutrients to plants and improve soil fertility. Heading 3102 specifically covers nitrogenous fertilizers. Sodium nitrate is a naturally occurring mineral, historically sourced from the Atacama Desert in Chile. For a product to be classified under 310250, it must be intended for agricultural use. The HS code system distinguishes between technical-grade chemicals and agricultural-grade fertilizers to manage trade statistics and apply appropriate tariffs or subsidies related to food production. This classification remains consistent whether the sodium nitrate is in a crude state or has been refined, provided its end-use remains soil enrichment. The inclusion of sodium nitrate in this heading is vital for monitoring the global trade of agricultural inputs, which are often subject to specific environmental regulations and import duties designed to support local farming sectors. Furthermore, the classification helps in identifying products that may be subject to dual-use regulations, as certain nitrogenous compounds can be diverted for non-agricultural purposes. Proper documentation must specify the nitrogen content and the intended application to ensure the correct application of the 310250 code during the customs entry process.

Products Included

• Natural sodium nitrate (Chile saltpeter)
• Refined sodium nitrate for agricultural applications
• Nitrogenous mineral fertilizers containing sodium nitrate
• Sodium nitrate prills or granules for soil application

Common Misclassification

A common error is classifying Chile saltpeter under HS code 2834.21. Heading 2834 is reserved for nitrites and nitrates as pure chemical compounds. If the sodium nitrate is of high purity and intended for industrial purposes—such as the manufacture of glass, explosives, or as a food preservative—it belongs in Chapter 28 rather than Chapter 31. The distinction relies heavily on the intended use and the presentation of the product. Another potential confusion is with 3105, which covers fertilizers containing multiple fertilizing elements; however, pure sodium nitrate only provides nitrogen and thus stays in 3102.

FAQ

What is the HS code for Chile saltpeter?

The standard HS code for Chile saltpeter used as a nitrogenous fertilizer is 310250.

Can sodium nitrate be classified in Chapter 28?

Yes, if the sodium nitrate is an industrial chemical not intended for use as a fertilizer, it is classified under 2834.21.
