HS Code 9032.10 – Regulating or controlling instruments and apparatus; automatic type, thermostats
HS code 9032.10 is the 6-digit subheading for regulating or controlling instruments and apparatus, automatic type, thermostats. It is used for smart home thermostats, industrial temperature controllers, automotive engine thermostats, refrigeration thermostats and oven thermostats.
What HS 9032.10 covers
This HS code specifically covers automatic thermostats, which are crucial regulating or controlling instruments designed to maintain a desired temperature. These devices are widely traded globally, serving diverse sectors such as HVAC (heating, ventilation, and air conditioning), appliance manufacturing, automotive, and industrial process control. Importers include manufacturers integrating thermostats into their products, as well as distributors supplying the construction and automotive aftermarket. Exporters are often countries with strong electronics manufacturing capabilities and a focus on energy efficiency solutions. Key aspects of trade involve technological advancements like smart home integration, energy-saving features, and robust industrial designs, reflecting a global push towards automation and environmental control.

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).
