About heading 9032

Automatic regulating or controlling instruments and apparatus; parts and accessories thereof

Heading 9032 covers automatic regulating or controlling instruments and apparatus, meaning devices that hold a variable such as temperature, pressure, flow or voltage at a set value, plus their parts and accessories. The heading splits first by article type: thermostats in 9032.10, manostats in 9032.20, other hydraulic and pneumatic controllers in 9032.81, all other controllers in 9032.89, and parts in 9032.90. Within those groups the rate depends on the end use, such as air conditioning, refrigeration or heating, industrial process control, or use in a 6, 12 or 24 V system.
