HS Code for Methacrylic acid

Methacrylic acid is classified under HS code 2916.13. This code is situated within the section for unsaturated acyclic monocarboxylic acids, their anhydrides, halides, peroxides, and peroxyacids. Methacrylic acid is a carboxylic acid that serves as a vital monomer in the plastics and resin industry. The classification is determined by the presence of the carboxylic acid functional group (-COOH) and the carbon-carbon double bond, making it an unsaturated acyclic compound. Under the General Rules for the Interpretation of the Harmonized System (GRI), specifically GRI 1, the product is classified according to the terms of the headings and any relative section or chapter notes. Chapter 29 notes specify that the headings only cover separate chemically defined organic compounds. Methacrylic acid, even when containing added stabilizers (such as hydroquinone) to prevent spontaneous polymerization during transport, remains classified here.

Products Included

• Methacrylic acid (monomer)
• Salts of methacrylic acid
• Sodium methacrylate
• Potassium methacrylate

Common Misclassification

A frequent misclassification occurs with HS code 2916.11, which is for Acrylic acid. While chemically similar, the presence of the methyl group in methacrylic acid necessitates its own specific subheading. Another common error is classifying the acid under 2916.14, which is reserved for the esters of methacrylic acid (like methyl methacrylate). Additionally, if the acid has already polymerized into a plastic form, it must be classified in Chapter 39 (specifically 3906) rather than Chapter 29.

FAQ

What is the HS code for Methacrylic acid?

The HS code for methacrylic acid and its salts is 2916.13.

Are stabilizers allowed in this classification?

Yes, according to Chapter 29 Note 1(f), the addition of an anti-dusting agent or a stabilizer (including an anti-oxidant) necessary for preservation or transport does not exclude the chemical from this heading.
