HS Code for Acrylic acid

Acrylic acid is classified under Harmonized System (HS) code 291611 due to its specific chemical structure as an unsaturated acyclic monocarboxylic acid. HS Chapter 29 is dedicated to organic chemicals, providing a detailed classification system based on chemical composition and functional groups. Within this chapter, Heading 2916 covers acyclic monocarboxylic acids, their anhydrides, halides, peroxides, peroxyacids, and their derivatives. Subheading 2916.11 is precisely designated for "Unsaturated acyclic monocarboxylic acids; acrylic acid and its salts." Acrylic acid (CH2=CHCOOH) is the simplest unsaturated carboxylic acid, featuring a carbon-carbon double bond (making it unsaturated) and a single carboxylic acid group (making it monocarboxylic). Its acyclic nature means it does not form a ring structure. The explicit mention of "acrylic acid" within this subheading provides a clear and unambiguous classification for this crucial chemical intermediate, ensuring consistent identification in international trade.

Common Misclassification

Acrylic acid can sometimes be confused with other carboxylic acids or related unsaturated compounds. A common misclassification might involve HS 2915.21, which covers Acetic acid. While both are carboxylic acids, acetic acid is a saturated monocarboxylic acid (CH3COOH), lacking the carbon-carbon double bond present in acrylic acid. This fundamental structural difference is key for accurate classification. Another potential point of confusion is with HS 2916.12, which covers Methacrylic acid. Methacrylic acid is also an unsaturated acyclic monocarboxylic acid, but it differs from acrylic acid by having a methyl group attached to the alpha-carbon of the double bond. Careful attention to the specific chemical structure and the presence or absence of saturation and substituents is essential for correct HS classification.

FAQ

What is the HS code for Acrylic acid?

The Harmonized System (HS) code for Acrylic acid is 291611. This code specifically identifies it as an unsaturated acyclic monocarboxylic acid, explicitly naming "acrylic acid and its salts."

What are the main applications of Acrylic acid?

Acrylic acid is a vital chemical building block with diverse applications. Its primary use is in the production of superabsorbent polymers (SAPs), which are extensively used in diapers and feminine hygiene products. It is also a key monomer for manufacturing acrylic esters, which are then used in paints, coatings, adhesives, and textiles. Furthermore, it is utilized in the production of various polymers and copolymers for water treatment and detergents.
