Overview

This HTS category, 9902.04.33, specifically covers Isopropyl (3-chlorophenyl)carbamate, also known as Chlorpropham and identified by CAS No. 101-21-3. This chemical compound is primarily utilized as a plant growth regulator, commonly employed as a sprout inhibitor for potatoes and onions during storage. Its classification within Chapter 99 indicates it is subject to temporary legislation, modifications, or additional import restrictions, often linked to agricultural programs or trade agreements, and is provided for under the more general subheading 2924.29.43 which pertains to other acyclic amides, etc.

As this node is a leaf node within Chapter 99, it does not have further subdivisions. Its distinction from other sibling categories within the HTS database, such as live animals (Chapters 01) or various manufactured goods, lies in its specific chemical nature and its designated temporary import control status under the Special Classification Provisions. While other chemical compounds might be found in different HTS chapters (e.g., Chapter 29 for organic chemicals), Chlorpropham's inclusion here signifies a distinct regulatory framework applied to its importation.
