2710.20.10.13 - Containing more than 15 ppm but not more than 500 ppm of sulfur

This classification, HTS Code 2710.20.10.13, covers specific types of distillate and residual fuel oils that fall within the broader category of petroleum oils. These oils are characterized by their sulfur content, precisely defined as containing more than 15 parts per million (ppm) but not more than 500 ppm of sulfur. This precise sulfur threshold is a critical determinant for classifying these fuels, influencing their potential uses and the regulatory requirements associated with their importation.

Distinguishing this category from its siblings is crucial for accurate classification. HTS Code 2710.20.10.11 encompasses lighter fuel oils with a sulfur content of 15 ppm or less, often referred to as ultra-low sulfur diesel. Conversely, HTS Code 2710.20.10.14 includes fuel oils with a sulfur content exceeding 500 ppm, typically designated as high-sulfur fuel oils. Therefore, 2710.20.10.13 occupies a specific niche for oils with an intermediate sulfur level.

As this is a leaf node within the HTS, there are no further subcategories to introduce. Classification within this specific code is finalized once the criteria of containing between 15 and 500 ppm of sulfur are met, alongside the preceding criteria of testing 25 degrees A.P.I. or more and having a Saybolt Universal viscosity at 37.8˚C of less than 45 seconds, classifying them as light fuel oils. Examples of products that might fall under this classification include certain grades of diesel fuel, heating oils, or marine fuels that meet these precise sulfur and viscosity specifications.
