Overview

This HTS category, 9902.06.91, specifically covers the chemical compound 2,5-Dichloro-3,6-bis[(9-ethylcarbazol-3-yl)amino]cyclo- hexa-2,5-diene-1,4-dione, also known by its common name Dianil (CAS No. 80546-37-8). Its inclusion within Chapter 99 signifies that it is subject to temporary legislation, temporary modifications under trade agreements, or additional import restrictions proclaimed pursuant to Section 22 of the Agricultural Adjustment Act. This particular classification indicates that while Dianil may have a primary classification under Chapter 29 (Organic Chemicals), it is currently subject to specific, non-permanent trade measures.

Distinguishing this category from its sibling HTS codes within Chapter 99 is crucial. While all Chapter 99 codes deal with temporary trade provisions, 9902.06.91 is unique in its direct reference to a specific chemical compound, Dianil, and its provision under a designated subheading (2933.99.79) of Chapter 29. Other sibling categories in Chapter 99 might cover broader categories of goods affected by trade agreements or agricultural restrictions, but this code targets a singular chemical substance with precise implications for import duties and regulations.

As this is a leaf node, there are no subcategories to introduce. Classification under 9902.06.91 relies on the precise identification of the chemical substance itself. Importers must verify that the goods presented for clearance are indeed 2,5-Dichloro-3,6-bis[(9-ethylcarbazol-3-yl)amino]cyclo- hexa-2,5-diene-1,4-dione (Dianil), and that it is being imported under the conditions stipulated by the temporary legislation associated with this HTS code. Compliance with the underlying provisions of subheading 2933.99.79, along with the specific Chapter 99 restrictions, is paramount.
