Classification of pressure switch under HS 9032.20
Pressure switches are classified under HS code 903220 when they function as automatic regulators, also known as manostats. While many electrical switches are found in Chapter 85, a pressure switch that is designed to automatically control a pressure level by opening or closing an electrical circuit at a specific set point is classified in Chapter 90. Heading 9032 covers automatic regulating or controlling instruments. Subheading 903220 specifically covers manostats. These devices are used in various applications, such as air compressors, water pumps, and HVAC systems, to ensure that the system pressure remains within safe or operational limits. The distinction between a simple switch and a manostat depends on whether the device is intended to regulate a variable (pressure) as part of an automated system. According to the HS Explanatory Notes, manostats consist of a pressure-sensitive element and a device which acts on an electrical circuit or a valve to maintain the pressure. Because they perform a control function based on a measured variable, they are treated as precision instruments.

Codes often confused with 9032.20
Common mistake. Pressure switches are often misclassified under 853650, which covers other electrical switches for a voltage not exceeding 1,000 V. However, if the switch is designed to maintain a pressure at a set point (acting as a manostat), Note 7 to Chapter 90 directs the classification to 903220. Another common error is 902620, which is for measuring instruments; a switch does more than measure—it triggers an action to regulate the system, which is the defining characteristic of heading 9032.
Top exporters and importers of HS 903220 (the code used for pressure switch), 2025
In 2025, the largest exporter of HS 903220 (the code used for pressure switch) 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 switch
What is the HS code for Pressure switch?
The HS code for Pressure switch is 903220 (Regulating or controlling instruments and apparatus; automatic, manostats). The HS code for a pressure switch functioning as an automatic regulator (manostat) is 903220.
How do I classify Pressure switch for customs?
Pressure switch is classified under HS code 903220 — Regulating or controlling instruments and apparatus; automatic, manostats. This is a 6-digit subheading level code.
Why is a pressure switch not in Chapter 85?
If the switch is an automatic regulator (manostat) that maintains a pressure level, it is specifically included in Chapter 90 under heading 9032, which takes precedence over general electrical switches.
Which countries are the top exporters of pressure switch (HS 903220)?
In 2025, the top exporters of HS 903220 (the code used for pressure switch) 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 switch (HS 903220)?
In 2025, the top importers of HS 903220 (the code used for pressure switch) 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 switch the same in all countries?
The base HS code 903220 for Pressure switch is internationally standardized for the first 6 digits across 200+ countries. Individual countries may add additional digits for national tariff lines and specific classifications.
What is the NCM code for pressure switch in Brazil?
In Brazil, pressure switch (HS 903220) is classified under NCM 9032.20.00.
