Overview

This HTS category, 9902.05.09, designates a specific chemical compound, Disodium 2,2'-[biphenyl-4,4'-diyldiethene-2,1-diyl]dibenzenesulfonate (CAS No. 27344-41-8). It is important to note that while this code falls under Chapter 99, which pertains to temporary legislation and special provisions, its primary classification is for a particular organic chemical substance. The parenthetical reference to subheading 2930.90.29 indicates its underlying classification within the standard chemical sections of the HTS, highlighting its nature as a complex organosulfur compound.

Unlike the broad categories found in the initial chapters of the HTS (e.g., live animals), this node represents a highly specific chemical entity. Its distinction lies in its precise molecular structure and chemical name. While other entries within Chapter 99 might cover broad classes of goods subject to temporary measures, 9902.05.09 is dedicated to a single, defined substance, irrespective of any temporary or special import restrictions that may be associated with its inclusion in Chapter 99.

As this is a leaf node, there are no further subcategories to explore. The classification is precise and final for this particular compound. Therefore, for practical classification, import and export professionals should focus on confirming the identity of the substance and referencing its CAS number and chemical name against the description provided. The presence of this code within Chapter 99 suggests that while the substance itself is classified, its importation may be subject to specific, potentially temporary, trade policies or restrictions.
