2916.11.00.00 - Acrylic acid and its salts

This HTS category, 2916.11.00.00, specifically encompasses acrylic acid and its various salts. Acrylic acid is a fundamental organic compound characterized by its unsaturated acyclic structure and a single carboxylic acid functional group. Its salts are formed when the acidic hydrogen of the carboxylic group is replaced by a metal cation. These substances are critical building blocks in the production of a wide array of polymers and other chemical intermediates used in industries such as textiles, coatings, adhesives, and plastics.

This classification is distinct from its siblings, particularly 2916.12, which covers the esters derived from acrylic acid. While both originate from acrylic acid, the esterification process fundamentally changes the chemical structure and properties. Similarly, it is differentiated from 2916.13.00.00, which deals with methacrylic acid and its salts, another unsaturated monocarboxylic acid but with a methyl group attached to the carbon chain, leading to different polymerization characteristics and applications.

As this node is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification decisions within this code will rely on a precise identification of the chemical substance as either acrylic acid itself or one of its salts. Proper documentation, including chemical analysis or manufacturer's specifications, will be essential to confirm that the imported or exported product accurately fits the description of acrylic acid or its salts, rather than a related derivative like an ester or a different unsaturated acid.
