2710.19.11.11 - Containing not more than 15 ppm of sulfur

This HTS classification, 2710.19.11.11, specifically identifies certain types of light fuel oils that are distinguished by their extremely low sulfur content. These are distillate and residual fuel oils, including blended products, which have a specific gravity testing at 25 degrees API or more, and a Saybolt Universal viscosity at 37.8°C of less than 45 seconds. Crucially, to fall under this subcategory, the product must contain no more than 15 parts per million (ppm) of sulfur. This strict sulfur limit is a key determinant for its classification.

This category is distinguished from its siblings by its very low sulfur threshold. HTS code 2710.19.11.13 covers similar light fuel oils but with a higher sulfur content, ranging from more than 15 ppm up to 500 ppm. Further up the hierarchy, 2710.19.11.14 encompasses oils with an even greater sulfur concentration, exceeding 500 ppm. Therefore, the primary distinguishing factor for 2710.19.11.11 is its adherence to the lowest sulfur limit among these closely related fuel oil categories.

As this is a leaf node in the HTS classification system, there are no further subcategories. The classification is finalized at this level based on the combination of physical properties (API gravity, viscosity) and the critical sulfur content. This means that any product meeting all the preceding criteria and containing no more than 15 ppm of sulfur will be classified under 2710.19.11.11, without further subdivisions. Examples of products that might fall here include highly refined heating oils or certain types of marine fuels that meet these stringent sulfur specifications.
