8421.29.00.65 - Other

This HTS subcategory, 8421.29.00.65, encompasses a broad range of filtering and purifying machinery and apparatus designed for liquids, excluding those specifically enumerated in preceding subheadings. It captures devices whose primary function is to separate impurities, solids, or undesirable components from liquids through various filtration or purification processes. This can include, but is not limited to, general-purpose liquid filters used in industrial, commercial, or domestic settings, as well as specialized apparatus not otherwise classified.

This classification is distinct from sibling category 8421.29.00.40, which specifically covers hydraulic fluid power filters with a pressure rating of 1,000 kPa or greater. Consequently, 8421.29.00.65 is for all other liquid filtering or purifying machinery and apparatus that do not meet the specific criteria of the hydraulic fluid power filter category. The key differentiator lies in the intended application and pressure specifications.

As this is a terminal node within the HTS structure, there are no further subcategories under 8421.29.00.65. Therefore, the classification determination for goods falling under this subheading relies on carefully assessing whether they are filtering or purifying machinery and apparatus for liquids and ensuring they do not fit into any more specific, preceding HTS categories. Examples might include simple strainer baskets, bulk water purification units for non-potable use, or general-purpose industrial liquid separation equipment.
