HS Code 8402.20 – Boilers; super-heated water boilers
HS code 8402.20 is the 6-digit subheading for boilers, super-heated water boilers. It is used for high-temperature hot water boilers, district heating boilers, industrial superheated water generators, thermal fluid heaters (if water-based and superheated) and large commercial hot water boilers.
What HS 8402.20 covers
This HS code specifically covers super-heated water boilers, which are designed to produce hot water at temperatures above 100°C, but without generating steam. These boilers are vital components in large-scale district heating systems, major commercial and institutional buildings, and specific industrial processes where high-temperature hot water is preferred over steam due to efficiency, safety, or system design considerations. The trade in these specialized boilers involves significant engineering expertise for high-pressure hot water systems, often integrated into broader energy infrastructure projects. Importers are typically municipalities, utility companies, and large industrial complexes, while exporters are specialized manufacturers with expertise in high-temperature hot water technology. The market is influenced by urban development, energy policy, and the expansion of district heating networks.

Codes often confused with 8402.20
Common mistake. Distinct from steam-generating boilers (84021x, 840219) because they produce superheated water, not vapor, and also from central heating boilers (8403) which typically operate at lower temperatures or for different applications.
Top exporters and importers of HS code 840220, 2025
In 2025, the largest exporter of HS code 840220 in UN Comtrade data was France, with 51% of world exports; the largest importer in UN Comtrade data was Kazakhstan, with 31% 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).
