This HTS category, 9902.07.13, specifically covers the herbicide Oxadiazon, scientifically identified as 3-[2,4-Dichloro-5-(1-methylethoxy)phenyl]-5-(1,1-dimethylethyl)-1,3,4-oxadiazol-2(3H)-one. Its primary use is in agriculture for the pre-emergence control of a wide range of annual grasses and broadleaf weeds in various crops, including rice, soybeans, and cotton. The CAS number 19666-30-9 serves as a unique identifier for this specific chemical compound.

As a category within Section XXII, which deals with special classification provisions and temporary legislation, this HTS code is distinct from the standard commodity classifications found in Chapters 1-98. It signifies goods subject to specific, often temporary, import restrictions or tariff treatments proclaimed under trade agreements legislation or Section 22 of the Agricultural Adjustment Act. Unlike other chemical products or agricultural inputs classified elsewhere in the HTS, this entry pertains to a particular regulated substance, indicating a special status requiring careful documentation and adherence to specific import requirements.

Since this is a leaf node in the HTS database, there are no further subcategories. This means that any importation of Oxadiazon falling under the provisions of this specific HTS code will be classified directly here, without needing to navigate through more granular subdivisions. Classification at this level is critical for ensuring compliance with any temporary import restrictions, quotas, or special duties that may be in effect for this compound.
