2710.19.06.50 - Other 🖩

This HTS classification, 2710.19.06.50, specifically covers "Other" distillate and residual fuel oils that test under 25 degrees A.P.I. These are heavier petroleum-based fuels characterized by a lower API gravity, indicating a higher density compared to lighter oils. This measurement reflects the specific gravity of the oil and is a key indicator for differentiating fuel types.

This category is distinguished from its siblings by its specific gravity range. The sibling categories are defined by their Saybolt Universal viscosity at 37.8°C, with one group having a viscosity of 45 to 125 seconds (No. 4-type fuel oils) and the other exceeding 125 seconds (heavy fuel oils). In contrast, this classification prioritizes the API gravity, specifically oils that are lighter than 25 degrees A.P.I., but still fall under the broader umbrella of distillate and residual fuel oils.

As this node is a leaf node, it has no further subcategories. Therefore, classification within this specific code is determined by the API gravity falling below 25 degrees, in conjunction with the product meeting the criteria of being a distillate or residual fuel oil that is not elsewhere specified. Examples of products that might fall here include certain grades of marine fuel or industrial fuels that are denser than lighter distillates but less viscous than the heavy fuel oils classified under sibling categories.
