8421.39.01.60 - Pneumatic fluid power filters, rated at 550 kPa or greater

This HTS subheading, 8421.39.01.60, specifically classifies pneumatic fluid power filters designed for high-pressure applications, defined by a pressure rating of 550 kPa or greater. These filters are integral components within hydraulic and pneumatic systems, responsible for removing contaminants such as dirt, debris, and moisture from the working fluid or gas. The primary function is to protect sensitive machinery and ensure the efficient and reliable operation of fluid power equipment.

This category is distinguished from its sibling, 8421.39.01.90 ("Other"), by the explicit requirement of a pressure rating of 550 kPa or greater. While both fall under the broader classification of "Other" filtering or purifying apparatus for gases, 8421.39.01.60 targets a specific subset characterized by their robust construction and suitability for high-pressure environments. This distinction is crucial for accurate customs declarations and ensures that the specialized nature and intended application of these filters are correctly identified.

As a leaf node, this category does not have further subcategories. Therefore, the classification is complete at this level, contingent upon meeting the specified criteria for pneumatic fluid power filters operating at or above 550 kPa. Importers and exporters should ensure that their goods precisely match this description and pressure rating to avoid misclassification.
