Products classified under HTS 2812.19.00
Phosgene Gas (Carbonyl Chloride)
Phosgene is a colorless, highly toxic gas with the chemical formula COCl2, classified as a chloride oxide of carbon under HTS 2812.19.00 due to its structure containing both carbon-oxygen and carbon-chlorine bonds. It is primarily used in industrial chemical synthesis for producing polycarbonates and polyurethane precursors.
Carbonyl Sulfide Chloride
A reactive chemical compound containing carbon, oxygen, sulfur, and chlorine bonds, fitting the definition of halide oxides of nonmetals in HTS 2812.19.00. It serves as an intermediate in organic synthesis and specialty chemical production.
Chlorocarbonyl Difluoride
Also known as carbonyl chloride fluoride, this is a mixed halide oxide of carbon classified under HTS 2812.19.00 for other chloride oxides of nonmetals. It is utilized in the production of fluorochemicals and as a reagent in pharmaceutical synthesis.
Thiocarbonyl Chloride (Thiophosgene)
Thiophosgene (Cl2C=S) is a yellow liquid that qualifies as a chloride of nonmetals under HTS 2812.19.00 due to its carbon-chlorine bonds analogous to phosgene. Commonly used in organic chemistry for converting alcohols to chlorides.
Oxalyl Chloride
Oxalyl chloride ((COCl)2) is a colorless liquid used as a chlorinating and dehydrating agent, classified in HTS 2812.19.00 as a chloride of nonmetals. Its structure features carbon-chlorine bonds meeting Chapter 28 definitions for inorganic acid chlorides.
