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.

Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

2917.19.00Same rate: Free

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.

2916.19.00Same rate: Free

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.

2916.39.00Same rate: Free

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.

Import Tips & Compliance

• Ensure the product is clearly identified as pimelic acid with its chemical formula (C7H12O4) on the commercial invoice to avoid misclassification

• Verify the duty rate applicable for your country of origin under the Most-Favoured-Nation (MFN) tariff or any free trade agreement

• If importing for industrial use, confirm whether the product is subject to any end-use or import permit requirements under the Canadian Environmental Protection Act
