Crude soybean oil is the product of initial solvent extraction or pressing, and may be degummed (phospholipids removed) but is otherwise unrefined. Refining involves alkali neutralization, bleaching, and deodorization to remove free fatty acids, color bodies, and volatile compounds. Once those steps are complete, the oil classifies under 150790 rather than 150710.

Soybean oil from certain origins has been the subject of antidumping and countervailing duty investigations. Importers should check the current scope of any active orders with the US International Trade Commission and Commerce Department, as duty liability depends on the specific country of origin and the tariff line.
