Overview

This HTS category, 9902.01.24, specifically covers Sulfamic acid, identified by CAS Number 5329-14-6. It is important to note that this classification is for "provided for in subheading 2811.19.61," indicating that its primary classification elsewhere in the tariff schedule is as a general chemical compound. However, this specific 9902 code signifies a special provision, often related to temporary legislation, trade agreements, or agricultural adjustment measures as outlined in Section XXII of the Harmonized Tariff Schedule.

Distinguishing this category from its siblings within Chapter 99 is crucial. While other 99xx codes might cover different temporary provisions, trade agreements, or agricultural restrictions, 9902.01.24 is uniquely dedicated to Sulfamic acid under these specific circumstances. Unlike the primary chemical classifications in Chapters 1-97, this code points to a conditional or temporary import status rather than the inherent nature of the chemical itself.

As this is a leaf node, there are no further subcategories. Classification under 9902.01.24 will depend on adherence to the specific regulations or proclamations that have designated Sulfamic acid for this special treatment. Importers must ensure they meet all the requirements associated with this temporary provision to correctly classify and import the product.
