9902.03.22 - 4-(2,4-Dichlorophenoxy) butyric acid (2,4-DB) (CAS No. 94-82-6) (provided for in subheading 2918.99.20)

This HTS classification, 9902.03.22, pertains to a specific chemical compound, 4-(2,4-Dichlorophenoxy) butyric acid, also known as 2,4-DB, identified by CAS Number 94-82-6. It is important to note that this classification is situated within Chapter 99 of the Harmonized Tariff Schedule, which is dedicated to temporary legislation, temporary modifications enacted under trade agreements, and additional import restrictions imposed under Section 22 of the Agricultural Adjustment Act. Therefore, the inclusion of 2,4-DB under this code signifies a special or temporary import status, rather than its primary classification under the standard chemical chapters of the HTS.

Distinguishing this specific entry from its siblings, which encompass a wide array of agricultural commodities and live animals, is straightforward. While the bulk of HTS Chapter 01, for example, deals with live animals, HTS Chapter 99, and specifically this code, addresses chemicals subject to particular import regulations or provisions, not the animals themselves. The "provided for in subheading 2918.99.20" note indicates that 2,4-DB would typically fall under a different, more general chemical classification if not for the Section 22 restrictions or other temporary measures applied here.

As this node represents a leaf node within Chapter 99, there are no further subcategories to explore. The classification is definitive for 2,4-DB under the specific conditions or regulations that necessitate its placement within Chapter 99. Classification professionals should refer to the underlying Section 22 proclamation or trade agreement legislation that triggered this entry to fully understand the import requirements and potential limitations associated with 2,4-DB when entered under this code.
