2710.20.10.07 - Containing more than 15 ppm but not more than 500 ppm of sulfur

This HTS category, 2710.20.10.07, specifically classifies fuel oils that fall within a defined range of sulfur content. These are distillate and residual fuel oils, further defined by their API gravity and Saybolt Universal viscosity, indicative of light fuel oils. The key differentiating factor for this specific code is that these fuel oils contain more than 15 parts per million (ppm) but not more than 500 ppm of sulfur by weight.

This classification distinguishes itself from its siblings based on precise sulfur content. HTS code 2710.20.10.05 covers similar fuel oils with a sulfur content of 15 ppm or less, representing ultra-low sulfur fuels. Conversely, HTS code 2710.20.10.08 is for fuel oils exceeding 500 ppm of sulfur, classifying higher sulfur content fuels. Therefore, the "more than 15 ppm but not more than 500 ppm" criteria is the sole determinant for classification under 2710.20.10.07.

As this is a leaf node within the HTS, there are no further subdivisions. Classification decisions within this category are finalized by the sulfur content analysis, alongside the preceding criteria of API gravity and viscosity as outlined in the parent categories. Practical applications would involve fuels used in various combustion engines and industrial heating processes where the specified sulfur limit is a regulatory or technical requirement.
