9902.04.30 - 3-(3,4-Dichlorophenyl)-1,1-dimethylurea (Diuron) (CAS No. 330-54-1) (provided for in subheading 2924.21.16)

This HTS code, 9902.04.30, specifically covers the chemical compound 3-(3,4-Dichlorophenyl)-1,1-dimethylurea, commonly known as Diuron. This designation is provided for within the temporary legislation and special provisions of Chapter 99, referencing its primary classification under subheading 2924.21.16. Diuron is primarily utilized as a herbicide, disrupting photosynthesis in target plants.

As a specific provision within Chapter 99, this code is distinct from the primary classification of agricultural chemicals found in other chapters. It is not a broader category for all herbicides or urea compounds but is reserved for Diuron under specific temporary measures. Therefore, its siblings would be other specific tariff provisions or temporary modifications, not general chemical categories.

Since HTS code 9902.04.30 is a leaf node, it does not contain further subcategories. Classification under this specific code is definitive for Diuron when imported under the conditions stipulated by the temporary legislation or trade agreements for which Chapter 99 is established. Its purpose is to apply unique duty rates, quantitative restrictions, or other trade measures to this particular chemical, separate from its standard classification under the chemical chapters of the HTSUS.
