Product classification
HS code for Hybrid boilers: 8402.19
Boilers, vapour generating boilers, including hybrid boilers n.e.c. in heading no. 8402.
Classification of hybrid boilers under HS 8402.19
Hybrid boilers, which typically combine different fuel sources or technologies (such as biomass and electricity or gas and solar thermal) to generate steam or vapour, are classified under HS code 8402.19. Heading 8402 covers steam or other vapour generating boilers. While specific subheadings like 8402.11 and 8402.12 cover watertube and firetube boilers respectively, 8402.19 serves as the category for other vapour generating boilers, including hybrid systems that do not fit the traditional single-source definitions. These units are essential in industrial applications where energy efficiency and redundancy are required. The classification is based on the primary function of the machine, which is the generation of high-pressure vapour for power or heating, rather than the specific combination of heating elements used.

Codes often confused with 8402.19
Common mistake. Hybrid boilers are often misclassified under HS code 8403.10, which is reserved for central heating boilers. The key distinction is that 8403 boilers are designed for space heating and operate at lower pressures, whereas 8402 boilers generate vapour for industrial processes or power. Additionally, they may be confused with 8419.19 (instantaneous water heaters), but 8402 is specific to vapour/steam generation.
Top exporters and importers of HS 840219 (the code used for hybrid boilers), 2025
In 2025, the largest exporter of HS 840219 (the code used for hybrid boilers) in UN Comtrade data was China, with 27% of world exports; the largest importer in UN Comtrade data was Saudi Arabia, with 8.9% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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 hybrid boilers
What is the HS code for Hybrid boilers?
The HS code for Hybrid boilers is 840219 (Boilers; vapour generating boilers, including hybrid boilers n.e.c. in heading no. 8402). Hybrid vapour generating boilers are classified under HS code 8402.19.
How do I classify Hybrid boilers for customs?
Hybrid boilers is classified under HS code 840219 — Boilers; vapour generating boilers, including hybrid boilers n.e.c. in heading no. 8402. This is a 6-digit subheading level code.
Can a hybrid boiler be classified under 8403?
Only if the boiler is specifically designed for central heating and does not generate steam or high-pressure vapour for industrial use; otherwise, 8402.19 is the correct code.
Which countries are the top exporters of hybrid boilers (HS 840219)?
In 2025, the top exporters of HS 840219 (the code used for hybrid boilers) in UN Comtrade data were China ($230M, 27% of world exports), Germany ($129M) and Italy ($92M). World exports came to about $840M, 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.
