2710.19.45.90 - Other

This HTS category, 2710.19.45.90, encompasses a broad range of "other" mixtures of hydrocarbons that do not fit into more specific classifications within the petroleum oil subheadings. The defining characteristic is that these mixtures contain by weight not over 50 percent of any single hydrocarbon compound. This implies a complex composition where no one hydrocarbon dominates the mixture to a degree exceeding half its weight.

It is crucial to distinguish this category from its sibling, 2710.19.45.45, which specifically covers insulating or transformer oils. While both may consist of hydrocarbon mixtures, the sibling category is designated for oils with specific electrical insulating properties and intended uses in electrical equipment. Category 2710.19.45.90, conversely, covers those mixtures that lack these specialized properties or are intended for different industrial or commercial applications where the proportion of any single hydrocarbon compound remains below the 50 percent threshold.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, classification within 2710.19.45.90 relies on the explicit criteria outlined in its description: the substance must be a petroleum oil or an oil from bituminous minerals (other than crude), not elsewhere specified or included, containing 70 percent or more of such oils as the basic constituents, not containing biodiesel or classified as waste oil, and critically, being a mixture of hydrocarbons where no single hydrocarbon compound exceeds 50 percent by weight. Examples might include certain industrial solvents, specialized cleaning agents, or specific fuel blends that do not meet the criteria for more narrowly defined categories.
