2934.10.20.00 - Other

This HTS classification, 2934.10.20.00, encompasses "Other" heterocyclic compounds containing an unfused thiazole ring, which are aromatic or modified aromatic. These are organic chemical compounds characterized by the presence of a thiazole ring that is not fused with any other ring system, and where the molecule exhibits aromatic properties or has been modified to achieve them. This specific category serves as a residual classification for such thiazole-containing compounds that do not fit into any more specific subheading.

The distinction between this subheading and its sibling, 2934.10.10.00 ("Products described in additional U.S. note 3 to section VI"), lies in whether the goods meet the specific criteria outlined in the aforementioned additional U.S. note. This note often pertains to particular uses, quantities, or specific product formulations that grant preferential treatment or have distinct classification rules. Therefore, goods classified under 2934.10.20.00 are those with an unfused thiazole ring, aromatic or modified aromatic character, that are *not* covered by the specific provisions of additional U.S. note 3.

As this is a leaf node, there are no further subcategories. Classification under this subheading requires careful analysis of the chemical structure to confirm the presence of an unfused thiazole ring and aromatic or modified aromatic properties, and to ensure the product does not fall under any more precisely defined tariff lines within Chapter 29. Examples of products that might fall here could include certain dyes, pharmaceutical intermediates, or specialized reagents that meet the described chemical criteria.
