2710.99 - Other:

This HTS category, 2710.99, encompasses "Other" waste oils that are not specifically enumerated under other waste oil subheadings. This broad classification captures a range of used or spent petroleum-derived oils and preparations thereof, which do not fall into the more specific categories. The key defining characteristic for inclusion here is that the material is a waste oil and does not meet the criteria for other specialized waste oil classifications.

Distinguished from its sibling category, 2710.91.00, this subheading does not contain regulated polychlorinated biphenyls (PCBs), polychlorinated terphenyls (PCTs), or polybrominated biphenyls (PBBs). The absence of these specific hazardous compounds is the primary differentiator. Therefore, goods classified under 2710.99 are those waste oils that are free from these particular contaminants.

The subcategories under 2710.99 further delineate these waste oils based on their original intended use or composition. These subdivisions include wastes derived from distillate and residual fuel oils, such as motor fuels and blending stocks, as well as wastes from kerosene and naphthas. Additionally, specific provisions are made for waste oils originating from lubricating oils and greases, whether or not they contain additives. The "Other" designation at the deepest level often implies a residual category for waste oils not covered by these more specific subdivisions within the broader waste oil classification.
