Product classification
HS code for Pressure controller: 9032.20
Regulating or controlling instruments and apparatus, automatic, manostats.
Classification of pressure controller under HS 9032.20
Pressure controllers, specifically those functioning as automatic manostats, are classified under HS code 903220. This classification is determined by the device's function as an automatic regulating or controlling instrument. Under the Harmonized System, Chapter 90 covers optical, photographic, measuring, and checking instruments. Heading 9032 specifically addresses automatic regulating or controlling instruments and apparatus. Subheading 903220 is reserved for manostats, which are devices designed to maintain a pressure of a liquid or gas at a pre-set level, or to follow a predetermined program of pressure changes, regardless of disturbances. These devices typically consist of a sensing element, a control mechanism, and an actuator. The classification applies when the device automatically compares the measured pressure to a set point and takes corrective action to minimize the deviation. This distinguishes them from simple measuring gauges, as the controller must have the capability to influence the process variable to maintain a specific state.

Codes often confused with 9032.20
Common mistake. Pressure controllers are often misclassified under 902620, which is for instruments that only measure or check pressure without providing automatic control. Another common error is using 8481, which covers valves; while a controller may operate a valve, the instrument that performs the automatic regulation logic is classified in 903220. Additionally, if the device is a simple electrical switch triggered by pressure, it might be confused with 8536, but if it functions as a manostat, 903220 takes precedence.
Top exporters and importers of HS 903220 (the code used for pressure controller), 2025
In 2025, the largest exporter of HS 903220 (the code used for pressure controller) 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).

Questions about pressure controller
What is the HS code for Pressure controller?
The HS code for Pressure controller is 903220 (Regulating or controlling instruments and apparatus; automatic, manostats). The HS code for an automatic pressure controller or manostat is 903220.
How do I classify Pressure controller for customs?
Pressure controller is classified under HS code 903220 — Regulating or controlling instruments and apparatus; automatic, manostats. This is a 6-digit subheading level code.
How does a controller differ from a pressure gauge?
A pressure gauge (902620) only displays or measures the pressure, whereas a pressure controller (903220) actively regulates the pressure to maintain a set point.
Which countries are the top exporters of pressure controller (HS 903220)?
In 2025, the top exporters of HS 903220 (the code used for pressure controller) in UN Comtrade data were Germany ($260M, 25% of world exports), Japan ($98M) and the United States ($82M). World exports came to about $1.0B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of pressure controller (HS 903220)?
In 2025, the top importers of HS 903220 (the code used for pressure controller) in UN Comtrade data were Germany ($192M, 17% of world imports), the United States ($93M) and Italy ($51M). World imports came to about $1.1B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Is the HS code for Pressure controller the same in all countries?
