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 category, 2935.90.13.00, encompasses a diverse group of sulfonamide compounds that do not fall under more specifically enumerated headings within the broader "Sulfonamides" classification. It includes several active ingredients used in agricultural chemicals, such as the herbicide Fomesafen and Halosulfuron methyl, alongside other specialized sulfonamide derivatives like N‐(2,6‐Dichloro‐3‐ methylphenyl)‐5‐ amino‐1,3,4‐triazole‐2‐sulfonamide and 2,4‐Dichloro‐5‐ sulfamoylbenzoic acid. The inclusion of mixtures of ortho- and para-toluenesulfonamides further highlights the broad scope of this "Other" category for sulfonamides.

The distinction of this subheading from its siblings lies in the specific chemical structures and applications of the included substances. For instance, while sibling categories may list simpler sulfonamides or those with specific common names like Asulam (2935.90.06.00) or Metanilamide (2935.90.10.00), this heading captures more complex molecules or mixtures. It differs from 2935.90.15.00, which specifically covers o-Toluenesulfonamide, by including other sulfonamide derivatives and mixtures.

As a leaf node in the HTS classification system, 2935.90.13.00 does not have further subdivisions. Therefore, classification within this category relies on identifying the specific chemical compound or mixture and confirming that it is not more appropriately classified under a preceding, more specific sulfonamide heading. The presence of the exact chemical names within the description serves as the primary criterion for inclusion.
