2710.20.05.50 - Other

This classification, HTS Code 2710.20.05.50, pertains to distillate and residual fuel oils that, when tested, exhibit an A.P.I. gravity of less than 25 degrees. The A.P.I. gravity is a measure of how heavy or light a petroleum liquid is compared to water. A reading below 25 degrees indicates that the oil is heavier than water and generally possesses a higher density. This characteristic is a primary determinant for inclusion within this specific subcategory.

Distinguishing this category from its siblings is crucial for accurate classification. HTS Code 2710.20.05.10 covers fuel oils with a Saybolt Universal viscosity between 45 and 125 seconds at 37.8°C, often referred to as No. 4-type fuel oils. Meanwhile, HTS Code 2710.20.05.20 encompasses heavier fuel oils with a Saybolt Universal viscosity exceeding 125 seconds. In contrast, HTS 2710.20.05.50 is defined by its A.P.I. gravity rather than its viscosity, capturing heavier fuel oil fractions that may not neatly fit the viscosity parameters of its siblings.

As a leaf node, this classification does not have further subcategories. Therefore, the focus for classification purposes under 2710.20.05.50 is strictly on verifying that the fuel oil meets the criterion of having an A.P.I. gravity of less than 25 degrees, in addition to meeting the broader scope of distillate and residual fuel oils containing biodiesel. This specific physical characteristic serves as the definitive distinguishing factor for goods falling into this category.
