HS Code for Anthranilic acid

Anthranilic acid, also known as o-aminobenzoic acid, and its esters and salts are classified under HS code 2922.43. This classification is part of the category for oxygen-function amino-compounds, specifically amino-acids (other than those containing more than one kind of oxygen function) and their esters. Anthranilic acid is an aromatic compound containing both an amine group and a carboxylic acid group attached to a benzene ring. It serves as a vital intermediate in the chemical industry, particularly in the synthesis of dyes, perfumes, and pharmaceuticals. Because anthranilic acid is a precursor for the illicit manufacture of certain controlled substances (such as methaqualone), its international trade is strictly monitored under various drug precursor regulations. The classification 2922.43 is specific to this molecule and its derivatives, ensuring that customs authorities can track its movement accurately. The substance typically appears as a white to pale yellow crystalline powder and is soluble in hot water and organic solvents.

Common Misclassification

Anthranilic acid is sometimes misclassified under HS code 2916.31 (benzoic acid) because it is a derivative of benzoic acid. However, because it contains an amine group, the amino-compound heading 2922 takes precedence. It may also be confused with 2921.41 (aniline) due to its aromatic amine structure, but the presence of the carboxylic acid group (an oxygen function) moves it to 2922.
