9032.90.61.40 - Of manostats

This category, HTS 9032.90.61.40, specifically covers parts and accessories designed for use with manostats. Manostats are precision instruments used to maintain a constant gas pressure within a system, often employed in laboratory settings, chemical processing, or certain medical applications like anesthesia delivery. The classification at this level focuses on components that are integral to the functioning of these specialized pressure-regulating devices.

It is crucial to distinguish this category from its siblings. HTS 9032.90.61.20 covers parts for thermostats, which regulate temperature rather than pressure. HTS 9032.90.61.60 is for accessories of instruments and apparatus falling under subheading 9032.81, which includes other automatic regulating or controlling instruments and apparatus not elsewhere specified. Finally, HTS 9032.90.61.80 serves as a residual category for other parts and accessories within this broader group, meaning this 9032.90.61.40 designation is for those specifically and exclusively intended for manostats.

As a leaf node, this classification does not have further subdivisions. Therefore, the primary consideration for classification under 9032.90.61.40 is the demonstrable and intended use of the part or accessory with a manostat, as opposed to any other type of automatic regulating or controlling apparatus. This would typically be determined by the design, function, and explicit markings or documentation accompanying the item.
