2929.10.30.00 - 3,4-Dichlorophenylisocyanate

This HTS category encompasses 3,4-Dichlorophenylisocyanate, a specific organic chemical characterized by the presence of both isocyanate functional groups and a dichlorinated phenyl ring. As an isocyanate derivative, it plays a crucial role as an intermediate or reactant in the synthesis of various polymers, particularly polyurethanes, as well as in the production of pesticides and other specialty chemicals. Its unique chemical structure, featuring chlorine atoms at the 3 and 4 positions of the phenyl ring, dictates its reactivity and potential applications.

Within the broader classification of "Isocyanates," this entry is distinguished from its siblings by its precise chemical identity. For instance, it differs from toluenediisocyanates (2929.10.10.00 and 2929.10.15.00), which are based on toluene derivatives and are commonly used in large-scale polyurethane production. It also stands apart from the diverse range of other isocyanates listed in sibling categories, such as bitolylene diisocyanate, N-butylisocyanate, or 1,6-hexamethylene diisocyanate, each possessing distinct chemical structures and industrial uses. The presence of the dichlorophenyl moiety is the defining characteristic that separates 3,4-Dichlorophenylisocyanate from these related compounds.

As this is a leaf node within the HTS, there are no further subcategories. Classification under 2929.10.30.00 is therefore final for 3,4-Dichlorophenylisocyanate, provided the imported or exported material accurately matches this specific chemical identity and its stated purpose or composition. This level of detail ensures precise tariff application for this specialized organic compound.
