Product classification
HS code for Krypton: 2804.29
Gases, rare, other than argon.
Classification of krypton under HS 2804.29
Krypton is classified under HS code 2804.29, which covers rare gases other than argon. This classification is situated within Chapter 28, which encompasses inorganic chemicals, precious metal compounds, and rare-earth metals. Krypton is a noble gas, colorless and odorless, obtained through the fractional distillation of liquid air. In the Harmonized System, heading 2804 covers hydrogen, rare gases, and other non-metals. While argon has its own specific subheading (2804.21), other noble gases like krypton, xenon, and neon are grouped together under 2804.29. This classification applies to the gas in its pure elemental form, whether compressed in cylinders or in liquid form for industrial, lighting, or scientific applications. It is widely used in high-performance light bulbs and as an insulating gas in double-pane windows.
- Covers
- High-purity krypton gas
- Compressed krypton in steel cylinders
- Liquid krypton for industrial use
- Krypton for specialized laser applications
- Neon, xenon, and krypton mixtures (if predominantly rare gases)
- Also under 2804.29
- Airgas Helium
- Matheson Tri-Gas Neon
- Linde Krypton
- Praxair Xenon
Codes often confused with 2804.29
Common mistake. The most common misclassification is HS code 2804.21, which is exclusively for Argon. Another error involves HS code 2844.40, which would apply if the krypton were a radioactive isotope (such as Krypton-85). Additionally, if the gas is part of a complex prepared mixture for specific technical uses, it might fall under Chapter 38.
Top exporters and importers of HS 280429 (the code used for krypton), 2025
In 2025, the largest exporter of HS 280429 (the code used for krypton) in UN Comtrade data was Qatar, with about 29% of world exports; the largest importer in UN Comtrade data was China, with 15% 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 280429, not only krypton.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
