9032.90.61.60 - Of instruments and apparatus of subheading 9032.81

This HTS code, 9032.90.61.60, specifically covers parts and accessories for automatic regulating or controlling instruments and apparatus that fall under subheading 9032.81. Subheading 9032.81 encompasses automatic regulating or controlling instruments and apparatus other than thermostats and manostats, often used in a broad range of industrial, commercial, and domestic applications where precise environmental or process control is required, such as in HVAC systems, manufacturing processes, and scientific equipment. Therefore, this category is for components or accessories designed to be integrated into these more complex control systems.

It is crucial to distinguish this classification from its siblings. For instance, 9032.90.61.20 pertains specifically to parts and accessories of thermostats, which are typically designed to regulate temperature. Similarly, 9032.90.61.40 covers parts for manostats, which are used to regulate pressure. The current code, 9032.90.61.60, is for parts and accessories of regulating devices that are *not* thermostats or manostats, indicating a broader scope of application beyond simple temperature or pressure control. The sibling 9032.90.61.80 is also designated for "Other" parts and accessories within this level, meaning this particular code is for a defined subset of regulating devices under 9032.81.

As this is a leaf node, there are no further subcategories. Classification under 9032.90.61.60 hinges on the determination that the part or accessory is intended for use with an instrument or apparatus classified under 9032.81, and that the instrument or apparatus is not a thermostat or a manostat. This requires a detailed understanding of the specific function and intended application of the controlling device to which the part or accessory belongs.
