HS Code 9032.20 – Regulating or controlling instruments and apparatus; automatic, manostats
HS code 9032.20 is the 6-digit subheading for regulating or controlling instruments and apparatus, automatic, manostats. It is used for pressure switches for air compressors, hydraulic pressure regulators, pneumatic pressure sensors with control output, vacuum switches and differential pressure controllers.
What HS 9032.20 covers
This category is dedicated to automatic manostats, which are instruments designed for the automatic regulation or control of pressure. These devices are essential across numerous industries, including HVAC, industrial machinery, automotive systems, medical equipment, and water treatment plants, where precise pressure management is critical for safety and operational efficiency. Importers typically include manufacturers of compressors, pumps, and hydraulic systems, as well as distributors serving maintenance and repair markets. Exporters are often nations with advanced manufacturing capabilities in precision engineering and fluid power. Key trade considerations include reliability, accuracy under varying conditions, and compliance with safety standards, as manostats often serve as critical safety cut-off or control components in complex systems.

Codes often confused with 9032.20
Common mistake. Manostats can be confused with general pressure gauges (902620) if their automatic regulating or controlling function is overlooked, or with other automatic controllers (903289) if not specifically pressure-related.
Top exporters and importers of HS code 903220, 2025
In 2025, the largest exporter of HS code 903220 in UN Comtrade data was Germany, with 25% of world exports; the largest importer in UN Comtrade data was Germany, with 17% 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).
