8481.10.00.40 - Filter-regulators and filter-regulator-lubricators

This HTS category, 8481.10.00.40, specifically covers filter-regulators and filter-regulator-lubricators. These are sophisticated pneumatic fluid power control devices designed to perform multiple functions within an air system. A filter-regulator combines the functions of removing contaminants from compressed air with regulating its pressure down to a usable level. A filter-regulator-lubricator additionally introduces a controlled amount of lubricant into the filtered and regulated air stream, which is essential for the longevity and smooth operation of pneumatic tools and actuators.

These units are distinct from their sibling category, 8481.10.00.60 ("Other"), which would encompass pneumatic fluid power pressure-reducing valves that do not include integrated filtering or lubricating capabilities. While both fall under the broader umbrella of pressure-reducing valves for pneumatic applications, the "filter-regulator" and "filter-regulator-lubricator" classifications are for units performing the combined functions as described.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, classification within 8481.10.00.40 depends on the specific combination of filtering, pressure regulation, and lubrication features present in the device. Importers should carefully examine the product's design and intended function to ensure it aligns with the comprehensive capabilities of a filter-regulator or a filter-regulator-lubricator.
