2710.99.05.00 - Testing under 25 degrees A.P.I. 🖩

This HTS category, 2710.99.05.00, specifically covers waste oils derived from distillate and residual fuel oils. The crucial classification criterion here is the American Petroleum Institute (A.P.I.) gravity test. Goods falling under this subheading have an A.P.I. gravity of *less than* 25 degrees. This indicates a relatively heavier oil compared to those with higher A.P.I. gravities, typically meaning they have a higher specific gravity and are less volatile. Examples may include certain types of used lubricating oils or industrial process waste streams that meet this specific gravity threshold.

This category is distinguished from its sibling, 2710.99.10.00, based solely on the A.P.I. gravity reading. While both subcategories pertain to waste oils from distillate and residual fuel oils, the determining factor is whether the A.P.I. gravity is 25 degrees or more (sibling) or less than 25 degrees (current category). This precise measurement is essential for customs authorities to accurately categorize and potentially apply different duty rates or regulations.

As this node is a leaf node within the HTS structure, there are no further subcategories. Therefore, the classification is definitive at this level, relying entirely on the nature of the waste oil (distillate or residual fuel oil origin) and the specific A.P.I. gravity test result being under 25 degrees. Any variations or further breakdowns of these oils would typically be addressed at a higher or lower hierarchical level if specific product types or processing methods warranted it.
