2710.19.11.08 - Containing more than 500 ppm of sulfur

This HTS classification pertains to light fuel oils, specifically Fuel Oils Nos. 2 and 3, that possess a sulfur content exceeding 500 parts per million (ppm). These oils are characterized by their API gravity of 25 degrees or more and a Saybolt Universal viscosity below 45 seconds at 37.8°C. This category is intended for products that meet these specific physical and chemical parameters, serving as a distinct classification for heavier sulfur content fuels within the light fuel oil group.

The critical differentiating factor for this classification is the sulfur content. It is distinct from its sibling categories which cover light fuel oils with significantly lower sulfur concentrations. Specifically, 2710.19.11.05 applies to oils containing not more than 15 ppm of sulfur, and 2710.19.11.07 covers oils with more than 15 ppm but not more than 500 ppm of sulfur. Therefore, any light fuel oil meeting the other criteria but containing over 500 ppm of sulfur will fall under this heading.

As this is a leaf node within the HTS, there are no further subcategories. This designation signifies that the product fully meets all the preceding descriptive criteria, from its petroleum origin and viscosity to its API gravity and a sulfur content exceeding 500 ppm. Importers and exporters should ensure that all these specifications are met to correctly classify goods under this tariff number.
