Overview

This HTS category, 9902.03.04, specifically covers Isophthaloyl chloride, identified by CAS No. 99-63-8. This chemical compound is a key intermediate used in the synthesis of various polymers, including aramid fibers and polyesters, and is provided for under subheading 2917.39.70 of the Harmonized Tariff Schedule. Its inclusion within Chapter 99 indicates it is subject to temporary legislation, trade agreement modifications, or specific import restrictions.

As a "leaf node," this category does not have further subdivisions. Its uniqueness lies in its precise identification of Isophthaloyl chloride. While other categories within Chapter 99 may cover other chemicals or goods subject to temporary measures, this specific code isolates Isophthaloyl chloride for distinct tariff treatment and regulatory oversight. It is crucial to differentiate this from its primary classification under Chapter 29, which details organic chemicals, to ensure compliance with any applicable special provisions. The classification here highlights the application of Section XXII, signaling potential trade policy implications beyond standard chemical tariff lines.
