Overview

This HTS category, 7325.10.00.30, specifically covers valve and service boxes made from nonmalleable cast iron. These articles are typically designed to house and protect underground utility valves, such as water or gas valves, and other service connections, allowing for access for maintenance and operation. Their primary function is to provide a secure and durable enclosure for these critical infrastructure components, preventing damage from external forces and environmental elements.

While sharing the broader classification of "Other cast articles of iron or steel" and "Of nonmalleable cast iron" with its siblings, 7325.10.00.30 is distinguished by its specific purpose of enclosing valves and service connections. Unlike manhole covers (7325.10.00.10), catch basins (7325.10.00.20), cleanout covers (7325.10.00.25), or meter boxes (7325.10.00.35), valve and service boxes are designed to protect the internal mechanisms of utility valves and associated piping, rather than providing access to manholes, drainage systems, or utility meters. The "Other" category (7325.10.00.80) serves as a residual category for nonmalleable cast iron articles that do not fit into the more specific sibling classifications.

As this is a leaf node in the HTS classification structure, there are no further subcategories under 7325.10.00.30. Therefore, the focus for classification at this level is on the accurate identification of goods whose primary design and function align with the enclosure and protection of underground valves and service apparatus, and are manufactured from nonmalleable cast iron.
