2710.19.11.07 - Containing more than 15 ppm but not more than 500 ppm of sulfur

This HTS classification, 2710.19.11.07, specifically covers light fuel oils that have undergone a distillation process or are residual fuel oils. These oils are characterized by their density, testing at 25 degrees API or more, and a relatively low viscosity, measured as less than 45 seconds on the Saybolt Universal scale at 37.8°C. Within the broader category of Fuel Oils Nos. 2 and 3, this specific sub-classification is further defined by its sulfur content.

The key differentiator for this category is the precise sulfur concentration within the oil. It is distinguished from its sibling categories by containing more than 15 parts per million (ppm) but not more than 500 ppm of sulfur. This is distinct from 2710.19.11.05, which has a sulfur content of 15 ppm or less, and 2710.19.11.08, which exceeds 500 ppm of sulfur. Therefore, the sulfur limit is the critical factor in selecting this particular classification.

As this node is a leaf node within the HTS structure, there are no further subcategories to introduce. The classification is complete at this level, with the combination of oil type (distillate/residual fuel oil), API gravity, Saybolt viscosity, and specific sulfur content defining the scope of goods covered. This allows for precise identification of these particular fuel oils for customs purposes.
