Pimelic Acid
Pimelic acid (heptanedioic acid) is a dicarboxylic acid with a seven-carbon chain, commonly used as a building block in the production of polymers, plasticizers, and pharmaceuticals. Although it is technically a dicarboxylic acid, it is classified under this tariff item as a cyclanic, cyclenic, or cycloterpenic monocarboxylic acid derivative due to its cyclic structure in certain forms. This classification aligns with the Customs Tariff of Canada's heading 2916, which covers cyclic monocarboxylic acids and their derivatives.

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 classified as a saturated acyclic dicarboxylic acid
Pimelic acid is a dicarboxylic acid; if not considered a cyclic derivative, it may fall under acyclic dicarboxylic acids.
If the product is presented as an unsaturated acyclic monocarboxylic acid
Some trade interpretations may treat pimelic acid as an acyclic compound, leading to classification under unsaturated acyclic monocarboxylic acids.
If the product is a derivative with additional functional groups
Halogenated, sulphonated, nitrated, or nitrosated derivatives of cyclic monocarboxylic acids may be classified under this item.
