HS Code 9032.90 – Regulating or controlling instruments and apparatus; automatic, parts and accessories
HS code 9032.90 is the 6-digit subheading for regulating or controlling instruments and apparatus, automatic, parts and accessories. It is used for PLC expansion modules, HMI panels for controllers, sensor probes for process controllers, control valve positioners and replacement circuit boards for VFDs.
What HS 9032.90 covers
This HS code covers the parts and accessories specifically designed for the automatic regulating or controlling instruments and apparatus classified under heading 9032. These components are crucial for the functionality, maintenance, and expansion of complex control systems across all industries. Trade in these items is essential for supporting the global installed base of automation equipment, ensuring operational continuity and allowing for system upgrades. Importers include system integrators, maintenance service providers, and end-users who require specific components for repair or customization. Exporters are typically the original manufacturers of the control systems or specialized component suppliers. Key aspects of trade involve precision manufacturing, compatibility with specific control platforms, and often proprietary technology, making reliable supply chains vital.

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).
