Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is oleic acid (cis isomer)
Oleic acid is named in subheading 2916.15; elaidic acid is not.
If the product is a hydrogenated oil rather than the pure acid
Processed oils and fats are classified in Chapter 15.

Import Tips & Compliance
• Provide a certificate of analysis confirming the product is elaidic acid and not a mixture of oleic and elaidic acids
• If the product is derived from hydrogenated oils, ensure it is purified to a single chemically defined compound
• Declare the exact isomer content, as mixtures of isomers may be classified differently under Chapter 29
