2924.19.11.20 - Dimethylformamide

This HTS category, specifically HTS 2924.19.11.20, covers Dimethylformamide (DMF). Dimethylformamide is an organic compound that serves as a versatile aprotic solvent and a reagent in various chemical synthesis processes. Its primary applications are found in the manufacturing of acrylic fibers, polyurethane products, pharmaceuticals, and pesticides, as well as in the electronics industry for cleaning and etching. The classification places it within the broader group of acyclic amides and their derivatives.

This specific classification differentiates Dimethylformamide from its siblings. HTS 2924.19.11.10 covers Acrylamide, a monomer used in the production of polyacrylamide, and HTS 2924.19.11.30 covers Methacrylamide, another related monomer. HTS 2924.19.11.50, "Other," is reserved for acyclic amides not specifically enumerated within this sub-heading. Dimethylformamide is distinguished by its unique chemical structure (a formamide derivative with two methyl groups attached to the nitrogen atom), which dictates its specific solvent properties and reactivity, setting it apart from the polymer precursors like acrylamide and methacrylamide.

As a leaf node within the HTS, this category does not have further subdivisions. Classification at this level is determined by the specific chemical identity of Dimethylformamide itself. Therefore, any import or export of this precise compound, when accurately declared, will fall under this HTS code, subject to relevant customs regulations and duty rates applicable to Chapter 29 chemicals.
