Thionyl Chloride
Thionyl chloride (SOCl2) is a colorless liquid used as a chlorinating and dehydrating agent in organic synthesis. It falls under HTS 2812.90.00.90 as a halide oxide of nonmetals, specifically a chloride oxide of sulfur, distinct from pure halides like hydrogen chloride. This classification applies to chemically defined inorganic compounds of nonmetals in this category.
Phosphoryl Chloride
Phosphoryl chloride (POCl3), also known as phosphoryl chloride, is a fuming colorless liquid used in phosphorylation reactions and as a dehydrating agent. Classified under HTS 2812.90.00.90 as a halide oxide of phosphorus (nonmetal). It meets Chapter 28 definitions for chemically defined inorganic compounds.
Carbonyl Chloride (Phosgene)
Carbonyl chloride, commonly called phosgene (COCl2), is a toxic gas used in polyurethane and isocyanate production. It qualifies as a halide oxide of carbon under HTS 2812.90.00.90 per Chapter 28 note 2(b). Strict handling due to extreme toxicity.
Titanium Tetrachloride
Titanium tetrachloride (TiCl4) is a colorless fuming liquid used in titanium metal production and smoke screens. Though titanium is a metal, it's classified here as a halide of a transition nonmetal-like compound under 2812.90 per HTS practice. Chemically defined per Chapter 28.
