HS code for Hydrogen: 2804.10
Hydrogen.
Classification of hydrogen under HS 2804.10
Hydrogen is classified under HS code 2804.10, which falls within Chapter 28 of the Harmonized System. This chapter is dedicated to inorganic chemicals, precious metal compounds, and rare-earth metals. Specifically, heading 2804 covers hydrogen, rare gases, and other non-metals. The classification of hydrogen under this code is determined by its status as a pure chemical element. According to the General Rules for the Interpretation (GRI) of the Harmonized System, chemical elements in their pure form are generally classified in Chapter 28, provided they are not packaged for specific uses that would redirect them to other chapters. Hydrogen is the simplest and most abundant element, and for international trade, it is classified here regardless of whether it is in a gaseous or liquefied state. The code 2804.10 is specific to hydrogen and does not include other gases like nitrogen or oxygen, which have their own subheadings under 2804.

Codes often confused with 2804.10
Common mistake. Hydrogen is frequently misclassified under HS code 2711.29, which covers other petroleum gases and gaseous hydrocarbons. While hydrogen is often used as a fuel, Chapter 27 is reserved for mineral fuels and oils. Another common error is confusing it with HS code 2801, which covers halogens like fluorine and chlorine. It is essential to distinguish hydrogen as a non-metal element under 2804.10 to ensure regulatory compliance and correct duty application.
Top exporters and importers of HS 280410 (the code used for hydrogen), 2025
In 2025, the largest exporter of HS 280410 (the code used for hydrogen) in UN Comtrade data was Canada, with 37% of world exports; the largest importer in UN Comtrade data was the United States, with 33% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 280410, not only hydrogen.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about hydrogen
What is the HS code for Hydrogen?
The HS code for Hydrogen is 280410 (Hydrogen). The HS code for hydrogen is 2804.10, which applies to the element in both gaseous and liquid forms.
How do I classify Hydrogen for customs?
Hydrogen is classified under HS code 280410 — Hydrogen. This is a 6-digit subheading level code.
Does the purity of hydrogen affect its HS code?
Generally, no. As long as the substance is essentially pure hydrogen, it remains under 2804.10. However, if it is mixed with other gases to create a specific fuel blend, it may be classified under Chapter 27.
Which countries are the top exporters of hydrogen (HS 280410)?
In 2025, the top exporters of HS 280410 (the code used for hydrogen) in UN Comtrade data were Canada ($78M, 37% of world exports), the Netherlands ($41M) and Belgium ($21M). World exports came to about $211M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of hydrogen (HS 280410)?
