About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS classification covers sulfanilic acid, a specific aromatic amine derivative. Sulfanilic acid is a key intermediate in the synthesis of various dyes, pharmaceuticals, and optical brighteners. Its chemical structure features both an amino group (-NH2) and a sulfonic acid group (-SO3H) attached to a benzene ring, making it a unique compound within the aniline derivatives family.

Within the broader category of aniline derivatives and their salts, sulfanilic acid (2921.42.22.00) is distinguished from its siblings by its specific chemical composition and common industrial applications. For example, it differs from metanilic acid (2921.42.21.00) by the position of the sulfonic acid group on the benzene ring. It is also distinct from other aniline derivatives listed as siblings, such as N,N-dimethylaniline or various dichloroanilines, due to the presence of the sulfonic acid moiety.

As a leaf node within the HTS, the classification 2921.42.22.00 represents a specific product without further subdivisions at this level. Therefore, the focus for classification here relies on accurate identification of sulfanilic acid itself. Importers and exporters must ensure that the goods presented precisely match the chemical identity of sulfanilic acid to avoid misclassification.
