2710.19.11.03 - Containing more than 15 ppm but not more than 500 ppm of sulfur

This HTS classification, 2710.19.11.03, specifically covers diesel fuel oils that fall within a defined sulfur content range. These are refined petroleum products intended for use as fuel, characterized by their relatively low viscosity and testing 25 degrees API or more. The crucial differentiator for this category is its sulfur content, which must be greater than 15 parts per million (ppm) but not exceed 500 ppm. This precise sulfur limitation is a key factor for customs purposes, often relating to environmental regulations and fuel quality standards.

This specific classification distinguishes itself from its sibling categories based on sulfur content. HTS 2710.19.11.02 covers diesel oils with a sulfur content of 15 ppm or less, representing ultra-low sulfur diesel. Conversely, HTS 2710.19.11.04 encompasses diesel oils with a sulfur content exceeding 500 ppm, indicating higher sulfur formulations. Therefore, the goods classified under 2710.19.11.03 are essentially "low sulfur" diesel fuels, falling between these two extremes.

As this node represents a leaf node in the HTS classification, there are no further subcategories. The classification is complete at this level, with the defining characteristics being the product type (diesel oil), its API gravity and Saybolt viscosity, and its specific sulfur content range. When classifying diesel fuel, importers and exporters must carefully verify the sulfur analysis to ensure accurate placement within this detailed breakdown.
