Product classification
HS code for Gas geyser: 8419.11
Heaters, instantaneous gas water heaters, for domestic or other purposes.
Classification of gas geyser under HS 8419.11
A gas geyser, also known as an instantaneous gas water heater, is classified under HS code 8419.11. Heading 8419 covers machinery and plant equipment, whether or not electrically heated, for the treatment of materials by a process involving a change of temperature. Subheading 8419.11 is specifically dedicated to instantaneous or storage water heaters that use gas. Unlike traditional boilers used for central heating (which fall under 8403), a gas geyser is designed to heat water for immediate use in domestic or industrial applications. The classification is determined by the mechanical nature of the heat exchange process. Even though these devices are often used in homes, they are classified in Chapter 84 because they are considered mechanical appliances for temperature change, rather than simple domestic hardware found in Chapter 73.

Codes often confused with 8419.11
Common mistake. Gas geysers are often misclassified under 8419.19, which is the residual category for "other" water heaters, such as solar or electric storage heaters. However, if the unit is gas-powered and instantaneous, 8419.11 is the specific and correct code. They are also sometimes confused with 7321.81 (gas space heaters). The distinction lies in the medium being heated: 8419.11 is for heating water, while 7321.81 is for heating air. Finally, they should not be confused with central heating boilers of heading 8403, which are designed to circulate water through a closed-loop radiator system.

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).
