HS-4 · Heading

2804Hydrogen, rare gases and other non-metals

Chapter 28: Inorganic chemicals

Plain-language overview

Use HS-4 2804 when importing or exporting hydrogen, rare gases, or other non-metals such as nitrogen and oxygen. For instance, if you're shipping compressed hydrogen gas for industrial use, this heading is applicable.

When deciding between HS-6 lines, note that 280410 specifically covers hydrogen, while 280421 and 280429 pertain to argon and other rare gases, respectively. If you're dealing with argon gas, ensure you select 280421 to avoid misclassification.

If your shipment includes nitrogen, use HS-6 280430. For oxygen, select 280440. Each of these gases has distinct applications, so understanding their specific classifications will help you avoid delays or penalties during customs clearance.
