Oleic Acid (High Purity Vegetable) from Germany

High-purity oleic acid (cis-9-octadecenoic acid) is an unsaturated acyclic monocarboxylic acid, not a saturated one. However, if the product is technically processed to be saturated-equivalent or if it is a mixture of isomers, it may fall under Chapter 29. Assuming it is a separate chemically defined compound of oleic acid, it would be classified under heading 2915 as an unsaturated acyclic monocarboxylic acid, but since the tariff item is for 'other' saturated acids, this product may not belong here unless it is actually saturated. If it is oleic acid, it should be classified under a different tariff item for unsaturated acids.
