Overview

This HTS category, 9902.05.49, specifically addresses a particular chemical compound: 3-(2,4-Dichlorophenyl)-2-oxo-1-oxaspiro[4.5]dec-3-en-4-yl 2,2-dimethylbutanoate, commonly known as Spirodiclofen. It is important to note that while this compound has a primary classification under subheading 2932.20.10, its appearance in Chapter 99 signifies special circumstances, likely related to temporary legislation, trade agreements, or specific import restrictions under Section 22 of the Agricultural Adjustment Act. This means that goods entered under this code are subject to unique trade policies beyond their standard chemical classification.

Unlike the preceding sibling categories in Chapter 99, which likely deal with other forms of temporary trade measures or restrictions across a wide range of goods, this node is highly specific. It does not cover general agricultural products, manufactured goods, or other broad categories of imports. Instead, its scope is narrowly defined to Spirodiclofen, indicating a targeted regulatory approach for this particular chemical.

As a leaf node within the HTS database, category 9902.05.49 has no further subdivisions. This implies that any import of Spirodiclofen falling under this specific provision will be classified directly at this level, without breaking down into more granular categories. Classification professionals should therefore focus on verifying that the imported substance is indeed Spirodiclofen and that the conditions for its entry under Chapter 99 are met, rather than seeking further detail within this particular code.
