8481.80.50.90 - Other

This HTS category, 8481.80.50.90, encompasses a broad range of "other" manual valves and similar appliances not specifically enumerated under other subheadings within the 8481.80.50 "Hand operated" classification. These include a diverse array of control devices for pipes, tanks, and vessels that are actuated by manual force, such as levers, wheels, or push buttons. The key defining characteristic is their manual operation and their exclusion from more precisely defined sibling categories.

This category serves as a residual classification for hand-operated valves and cocks made of materials other than those specifically itemized. For instance, while 8481.80.50.40 is designated for pressure spray can valves and 8481.80.50.60 for common plumbing fixtures like bath and sink faucets, this subheading captures a wider spectrum of industrial, commercial, or specialized manual control devices. Examples might include certain types of manual shut-off valves for chemical processing, manual drain valves for industrial equipment, or specialized manual actuators for various fluid or gas control systems not fitting elsewhere.

As this is a terminal node in the HTS classification system, there are no further subcategories. Therefore, the classification into 8481.80.50.90 relies on a careful review of the product's specific function, its material composition, and its exclusion from more narrowly defined HTS categories. The principle of "last resort" applies, meaning items are classified here if they meet the general criteria of the parent headings but do not fit into any other specific subheading.
