8481.90.90.20 - Valve bodies

This HTS category, 8481.90.90.20, specifically covers valve bodies. These are the fundamental components that form the housing or casing of various types of valves, as described in the broader heading 8481. This includes valve bodies for pressure-reducing valves, thermostatically controlled valves, and other similar appliances used for controlling fluid flow in pipes, tanks, and similar systems. The classification focuses on the physical structure of the valve body itself, often manufactured from materials like brass, iron, steel, or plastics, and intended to house the internal operating mechanisms of the valve.

While this subheading deals with "Other" parts within the broader "Parts thereof" section, it is distinguished from its sibling, 8481.90.90.40 ("Other"), by its specific designation as a "valve body." This implies a focus on the primary structural element of the valve. The parent category, 8481.20, relates to oil or gas operational valves. Therefore, 8481.90.90.20 captures the bodies of such valves if they fall within the scope of 8481.20, differentiating them from other distinct parts like stems, discs, or bonnets which would be classified elsewhere.

As this is a leaf node within the HTS, there are no further subcategories to introduce. The classification for valve bodies is thus concluded at this level, emphasizing the precise identification of the physical component as the determining factor for classification.
