9902.09.34 - Abamectin (mixture of Avermectin A1a and Avermectin A1b) (CAS No. 155569-91-8) (provided for in subheading 3808.91.50)

This HTS classification, 9902.09.34, pertains to specific temporary modifications and additional import restrictions, particularly those imposed under Section 22 of the Agricultural Adjustment Act. The item classified here is Abamectin, a mixture comprising Avermectin A1a and Avermectin A1b, identified by CAS Number 155569-91-8. Crucially, this classification indicates that while Abamectin is generally provided for under subheading 3808.91.50, it is subject to special provisions within Chapter 99 due to temporary legislation or trade agreement mandates.

Unlike the sibling categories within the main HTS structure, which primarily deal with the classification of goods based on their inherent physical characteristics and intended use (e.g., live animals, agricultural products, manufactured goods), this Chapter 99 classification highlights a regulatory overlay. Its existence signifies that the standard classification of Abamectin under the agricultural or chemical chapters has been altered or supplemented by temporary trade policies. Therefore, the primary function of this node is to inform importers and customs officials of specific duties, quotas, or other restrictions that apply beyond the base tariff rate.

As this is a leaf node, there are no further subcategories to explore. The classification 9902.09.34 is specific to the described form of Abamectin and the associated temporary import measures. This means that any importation of this specific chemical compound, regardless of its ultimate use or formulation, must adhere to the provisions stipulated by this Chapter 99 heading, in addition to its primary classification. Understanding the distinction between the product's inherent classification and these temporary provisions is paramount for accurate customs declaration and compliance.
