Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If acrylic or methacrylic acid
Specific heading 2916.19.10 precedes and takes priority over 'other' unsaturated acids per numerical order rule.
If sold as vitamin F complex
Linoleic acid when marketed specifically as a vitamin derivative may shift to provitamins heading.
If in emulsified preparations for industrial use
Prepared chemical mixtures/emulsions containing unsaturated acids classify under Chapter 38.

Import Tips & Compliance
• Submit GC-MS analysis proving specific double bond positions to distinguish from other unsaturated acids
• Register with FDA if destined for food/supplement use; provide COA showing >98% purity
• Avoid common error of classifying under 2916.19.10 as acrylic/methacrylic - linoleic has long chain structure
