2710.20.10.03 - Containing more than 15 ppm but not more than 500 ppm of sulfur

This HTS classification, 2710.20.10.03, specifically covers diesel oils that contain a precise sulfur concentration. These oils are characterized by having more than 15 parts per million (ppm) but not exceeding 500 ppm of sulfur by weight. This specific sulfur content is a critical determinant for their classification within the broader category of distillate and residual fuel oils, particularly those designated as light fuel oils (having a Saybolt Universal viscosity at 37.8˚C of less than 45 seconds) and falling under Fuel oils Nos. 2 and 3.

The defining characteristic of this category, distinguishing it from its siblings, is its intermediate sulfur content. HTS 2710.20.10.02 covers diesel oils with a sulfur content of 15 ppm or less, often referred to as ultra-low sulfur diesel. Conversely, HTS 2710.20.10.04 encompasses diesel oils with a sulfur content exceeding 500 ppm. Therefore, 2710.20.10.03 captures the range of diesel fuels that fall between these lower and higher sulfur thresholds.

As a leaf node in the HTS database, this category does not have further subdivisions. Its classification is solely determined by the specific sulfur content within the defined range. Examples of products falling under this classification would be diesel fuels intended for various transportation and industrial uses where the sulfur limitations align with environmental regulations or specific engine requirements that fall between the ultra-low and high sulfur categories.
