HS Code for Nitrogen

Nitrogen is classified under HS code 2804.30, which falls within Chapter 28 of the Harmonized System. This chapter is dedicated to inorganic chemicals, including precious metals, rare-earth metals, radioactive elements, or isotopes. Specifically, heading 2804 covers hydrogen, rare gases, and other non-metals. Nitrogen, being a non-metallic chemical element that exists as a gas at standard temperature and pressure, is explicitly categorized under subheading 2804.30. The classification remains consistent regardless of whether the nitrogen is in a gaseous or liquid state, provided it is not mixed with other gases in a way that changes its fundamental character as a pure chemical element. The General Rules for the Interpretation (GRI) of the Harmonized System dictate that products are classified according to the terms of the headings and any relative section or chapter notes. Since nitrogen is a distinct chemical element, it fits perfectly within the scope of 2804. This classification is used globally for customs declarations, ensuring that the substance is handled according to the specific safety and regulatory standards required for industrial gases.

Products Included

• Compressed nitrogen gas for industrial use
• Liquid nitrogen (refrigerated liquefied gas)
• High-purity nitrogen for laboratory applications
• Nitrogen used in food packaging (modified atmosphere)
• Nitrogen for tire inflation

Common Misclassification

Nitrogen is frequently confused with HS code 2804.40, which is designated for oxygen. While both are atmospheric gases, they are chemically distinct and must be declared separately. Another common error involves gas mixtures classified under 3824.99. If nitrogen is mixed with significant amounts of other gases (like argon or carbon dioxide) for specific industrial applications, it may lose its status as a pure element under 2804 and move to the chemical products category. Additionally, ammonia (NH3) is sometimes mistakenly associated with nitrogen's code, but it belongs under 2814.10 as a distinct chemical compound.

FAQ

What is the HS code for Nitrogen?

The HS code for Nitrogen is 2804.30, which covers the element in both gaseous and liquefied forms.

Is liquid nitrogen classified differently than gaseous nitrogen?

No, both liquid and gaseous nitrogen are classified under 2804.30. The physical state (liquid vs. gas) does not change the primary HS code classification for this pure element.
