8481.80.90.40 - Other

This HTS category, 8481.80.90.40, encompasses "Other" appliances falling under the broader classification of taps, cocks, valves, and similar devices for pipes, tanks, and vessels. Specifically, this subcategory covers pneumatic actuators not meeting the precise criteria of related entries. Pneumatic actuators are devices that use compressed air to generate mechanical motion, often used to operate valves remotely or automatically. This classification is for those pneumatic actuator-equipped valves that are not specifically described or enumerated in more specific subheadings, ensuring all relevant devices are accounted for.

It is crucial to distinguish this category from its sibling, 8481.80.90.35, which is reserved for control valves designed for proportional operation by a signal from a control device. While both involve control functions and may use pneumatic actuators, the sibling category specifically targets proportional control valves. This category, 8481.80.90.40, applies to pneumatic actuator-operated valves that do not fall under the proportional control definition, such as on/off actuated valves or those with pneumatic actuators performing a different type of function.

As a leaf node in the HTS database, this category does not have further subdivisions. Therefore, the classification of a specific product under 8481.80.90.40 hinges on its physical characteristics and intended use, confirming it is a valve or similar appliance equipped with a pneumatic actuator and not fitting into any more precisely defined categories. Guidance should be sought if ambiguity arises regarding the specific functionality or design of the pneumatic actuator in relation to established control valve definitions.
