9902.03.61 - α-N-Ethylanilinotoluene-3-sulfonic acid (CAS No. 101-11-1) (provided for in subheading 2921.42.90)

This HTS category, 9902.03.61, specifically covers α-N-Ethylanilinotoluene-3-sulfonic acid, identified by CAS Number 101-11-1. While this chemical compound is provided for under subheading 2921.42.90 in the main HTS structure (which generally deals with organic chemicals, specifically aromatic amines), this Chapter 99 entry signifies a temporary modification or restriction. This classification is utilized within the framework of Section XXII, which encompasses special classification provisions, temporary legislation, and actions taken under trade agreements or specific agricultural adjustment acts.

Distinguishing this category from its numerous siblings at the HTS Database Root level is crucial. The sibling categories, such as live animals (Chapters 01), live plants (Chapter 06), and various other product groupings, represent distinct broad areas of commerce. HTS 9902.03.61, however, falls under a specialized chapter (Chapter 99) dedicated to temporary measures. Therefore, its focus is not on a general product category but on a specific chemical with potential temporary import limitations or special reporting requirements, separate from the permanent classifications of other chapters.

As this is a leaf node, there are no further subcategories within 9902.03.61. The classification is precise and applies directly to the named chemical. Any import or export of α-N-Ethylanilinotoluene-3-sulfonic acid would be subject to the specific provisions and potential restrictions indicated by its presence in Chapter 99, requiring careful review of any accompanying notes or proclamations that define the temporary legislation or additional import restrictions associated with this particular HTS code.
