More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is specifically oleic, linoleic, or linolenic acid
These named unsaturated acyclic monocarboxylic acids are classified in a more specific subheading than 'other'.
If the acid has a cyclic structure rather than acyclic
Cyclic monocarboxylic acids fall under a different subheading within the same heading.
If the product is a saturated acyclic monocarboxylic acid
Saturated acids are classified in heading 2915, not 2916.
