HS Code 8402.12 – Boilers; watertube boilers with a steam production not exceeding 45t per hour
HS code 8402.12 is the 6-digit subheading for boilers, watertube boilers with a steam production not exceeding 45t per hour. It is used for package watertube boilers, industrial process steam boilers, small utility boilers, biomass-fired industrial boilers and waste heat recovery boilers (smaller scale).
What HS 8402.12 covers
This HS code covers watertube boilers with a steam production capacity not exceeding 45 tonnes per hour. These boilers are widely utilized across a diverse range of industries for process steam, heating, and smaller-scale power generation. They are a common sight in manufacturing plants, food processing facilities, hospitals, universities, and district heating systems, offering efficient and reliable steam generation. The trade in these boilers is more widespread than their larger counterparts, involving a broader base of manufacturers and buyers. Focus is often on energy efficiency, specific industry applications, and ease of installation and maintenance. Importers range from small and medium-sized enterprises to large institutions, while exporters are specialized boiler manufacturers catering to various industrial and commercial needs.

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).
