HS Code 8419.50 – Heat exchange units; not used for domestic purposes
HS code 8419.50 is the 6-digit subheading for heat exchange units, not used for domestic purposes. It is used for plate heat exchangers, shell and tube heat exchangers, air-cooled heat exchangers, finned tube heat exchangers and brazed plate heat exchangers.
What HS 8419.50 covers
This HS code encompasses industrial heat exchange units, vital components in virtually every process industry where temperature control is critical. These units facilitate the transfer of thermal energy between two or more fluids, without direct contact, enabling heating, cooling, condensation, or evaporation. They are indispensable in power generation, chemical processing, HVAC systems, refrigeration, food and beverage production, and oil and gas. International trade is robust, driven by industrial expansion, energy efficiency initiatives, and the need for reliable thermal management solutions. Importers include engineering firms, industrial plant operators, HVAC contractors, and manufacturers across diverse sectors. Exporters are specialized manufacturers of heat transfer equipment. Key trade considerations include material compatibility, pressure ratings, heat transfer efficiency, fouling resistance, and compliance with international standards (e.g., ASME).

Codes often confused with 8419.50
Common mistake. This code is specific to heat exchange units. It can be confused with general heating or cooling machinery (e.g., industrial furnaces 8417, refrigeration units 8418) if the primary function is not the exchange of heat between fluids. It's also distinct from boilers (8402, 8403) which generate steam or hot water.
Top exporters and importers of HS code 841950, 2025
In 2025, the largest exporter of HS code 841950 in UN Comtrade data was China, with 16% of world exports; the largest importer in UN Comtrade data was the United States, with 12% 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).
