2709.00.10.00 - Testing under 25 degrees A.P.I.

This HTS category, 2709.00.10.00, specifically covers crude petroleum oils and oils obtained from bituminous minerals that have a density test of less than 25 degrees API (American Petroleum Institute). The API gravity is a measure of how heavy or light a petroleum liquid is compared to water. A reading below 25 degrees API indicates a heavier, denser crude oil. These oils are the raw, unrefined product directly from the earth or bituminous materials.

This classification is distinguished from its sibling category, 2709.00.20, based solely on the API gravity test result. While both cover crude petroleum oils, the differentiating factor is the specific density. Category 2709.00.10.00 is for those oils that are heavier than water or have a lower API gravity reading, whereas 2709.00.20 is for those that are lighter than water, with an API gravity of 25 degrees or more. This distinction is crucial for customs purposes and can impact duties, taxes, and regulatory requirements.

As a leaf node within the HTS structure, there are no further subcategories for 2709.00.10.00. The classification is considered definitive for crude petroleum oils with a testing result below 25 degrees API. Therefore, for practical classification, it is essential to ensure the official API gravity test has been performed and documented, confirming the specific gravity and thus placing the crude oil within this precise tariff code.
