8481.80.90.10 - Ballcock mechanisms

This HTS category, 8481.80.90.10, specifically covers ballcock mechanisms. Ballcocks are essential components found in toilet cisterns, functioning as an automatic fill valve that controls the water level. They are designed to shut off the water supply once the tank has reached the desired level, preventing overflow.

While this category falls under "Other appliances" within the broader group of taps, cocks, valves, and similar appliances, it is distinct from its siblings. For instance, 8481.80.90.05 classifies solenoid valves, which operate electrically, a function not inherent to the mechanical operation of a ballcock. Similarly, 8481.80.90.15 covers self-operating regulator valves for various control variables; ballcocks, while self-operating to control water level, are specifically designed for toilet cistern applications and not for general pressure, temperature, or flow regulation.

As a leaf node, 8481.80.90.10 does not have further subcategories. Therefore, classification under this code relies on the precise identification of the goods as ballcock mechanisms used in sanitary ware. The key distinguishing factor is the specific design and primary function of regulating water refill in a toilet tank, differentiating it from other types of valves and control appliances.
