9902.03.21 - (+)-(R)-2-(2,4-Dichlorophenoxy)propanoic acid (Dichlorprop-p) (CAS No. 15165-67-0) (provided for in subheading 2918.99.18)

This HTS classification, 9902.03.21, specifically covers (+)-(R)-2-(2,4-Dichlorophenoxy)propanoic acid, also known as Dichlorprop-p, identified by CAS No. 15165-67-0. This is a specific organic chemical compound, often utilized as a herbicide, with a particular stereoisomeric form that is critical for its intended application. The inclusion of this item within Chapter 99 signifies that it falls under temporary legislation or modifications, often enacted due to trade agreements or specific agricultural adjustments. Its presence here indicates a specialized import status separate from its inherent chemical classification.

This category distinguishes itself by its specific chemical identity and its placement within temporary tariff provisions. Unlike the broader categories represented by sibling entries, which might cover general categories of goods like live animals or raw materials, 9902.03.21 is precise. It is not a general agricultural commodity but a highly specific chemical product subject to particular trade regulations. Its direct reference to a subheading within Chapter 29 (Organic Chemicals) further solidifies its nature as a defined chemical entity, but its 9900 series code highlights an overriding temporary trade condition.

As this is a leaf node, there are no further subcategories under HTS 9902.03.21. This means that all goods meeting the description of (+)-(R)-2-(2,4-Dichlorophenoxy)propanoic acid (Dichlorprop-p) will fall directly under this specific code when subject to the temporary legislation or trade provisions referenced by Chapter 99. Classification at this level relies entirely on accurately identifying the substance and confirming its applicability under the stated temporary tariff provisions.
