8481.80.30.40 - Other

This HTS category, 8481.80.30.40, encompasses "Other" hand-operated valves of iron or steel, specifically those made of iron. It serves as a residual classification for iron hand-operated valves that do not fit into the more specific types listed within the preceding sibling categories. Examples include lever-operated valves, or those with specialized control mechanisms not covered by gate, globe, plug, ball, or butterfly configurations, provided they are constructed primarily of iron and operated manually.

Crucially, this category distinguishes itself by its residual nature within the "Of iron" sub-classification. While siblings like 8481.80.30.10 (Gate type) and 8481.80.30.25 (Ball type) define valves by their distinct internal operational mechanisms, this code captures any other iron hand-operated valve not precisely defined by those specific types. The key differentiators are therefore the material (iron) and the method of operation (hand-operated), when the internal valve design does not align with the more narrowly defined sibling categories.

As this is a leaf node, there are no further subcategories to introduce. Classification decisions within this code will rely on a thorough examination of the valve's construction, its primary material composition being iron, its manual actuation, and ensuring it does not meet the criteria for any of the more specific valve types at the same level. The focus remains on the physical characteristics and functional purpose of the valve within the broader context of hand-operated, iron appliances for fluid or gas control.
