2710.99.10.00 - Testing 25 degrees A.P.I. or more

This HTS category, 2710.99.10.00, specifically covers waste oils that are derived from distillate and residual fuel oils, and importantly, have been tested to have an A.P.I. (American Petroleum Institute) gravity of 25 degrees or more. These are oils that have been used and are no longer fit for their original purpose as fuel, but still retain certain characteristics of petroleum-based products. The classification hinges on the specific gravity measurement as a key determinant for inclusion.

It is crucial to distinguish this category from its sibling, 2710.99.05.00, which covers similar waste oils but with an A.P.I. gravity *under* 25 degrees. The 25-degree A.P.I. mark serves as a critical dividing line for classification purposes, differentiating between lighter and heavier waste oil streams for customs declaration. Therefore, accurate testing and reporting of the A.P.I. gravity are essential for correct classification.

As a leaf node in the HTS structure, 2710.99.10.00 does not have further subdivisions. This means that all waste oils meeting the criteria of being from distillate and residual fuel oils and exhibiting an A.P.I. gravity of 25 degrees or more will be classified directly under this code. Practical examples include used heavy fuel oil or used diesel fuel that has been collected and meets the specified gravity threshold for recycling or disposal purposes.
