8421.29.00.15 - Oil-separation equipment

HTS Code 8421.29.00.15 specifically covers oil-separation equipment. This classification applies to machinery and apparatus designed for the primary purpose of removing oil or oil-based substances from liquids or other media. Examples include oil skimmers used for surface oil removal, centrifugal oil separators for industrial processes, and specialized filters designed to extract oil contaminants from water or other fluid streams. The key determining factor for classification under this heading is the dedicated function of oil separation.

While the broader category 8421.29 encompasses "Other" filtering or purifying machinery for liquids, 8421.29.00.15 carves out a specific niche for equipment whose principal function is oil separation. This distinguishes it from general-purpose liquid filters that may incidentally remove some oil but are not specifically designed for that primary purpose, or from equipment designed to separate other types of impurities.

As this is a leaf node, there are no further subcategories. Therefore, classification within 8421.29.00.15 relies on accurately identifying the equipment's core function as the separation of oil from other substances, based on its design, operational principles, and intended use. Customs officers will examine technical specifications and product literature to confirm this primary function.
