Products classified under HTS 2811.19.61
Hydrogen Selenide Gas
Hydrogen selenide (H2Se) is a colorless, toxic, flammable gas classified as an other inorganic acid under HTS 2811.19.61 due to its acidic properties and composition as a binary compound of nonmetal hydrogen and selenium. It is used in chemical synthesis and semiconductor doping.
Phosphorus Oxychloride
Phosphorus oxychloride (POCl3), also known as phosphoryl chloride, is a colorless liquid used in organic synthesis and as a chlorinating agent. It qualifies under HTS 2811.19.61 as an other inorganic oxygen compound of nonmetals, specifically phosphorus. Its classification stems from Chapter 28 notes on nonmetal acid derivatives.
Sulfuric Acid Oleum
Oleum, or fuming sulfuric acid (H2SO4 + SO3), is a highly corrosive liquid used in sulfonation processes. It falls under HTS 2811.19.61 as an other inorganic acid of nonmetals, distinct from standard sulfuric acid in 2807. This classification applies to its concentrated, oxygen-rich form per Chapter 28.
Nitrosyl Chloride
Nitrosyl chloride (NOCl) is a yellow-red gas or liquid used as a nitrosating agent in pharmaceuticals. Classified in HTS 2811.19.61 as an other inorganic oxygen compound of nitrogen (nonmetal), it fits Chapter 28 for halide oxides excluding those in 2812. Its reactivity defines its tariff placement.
Thionyl Chloride
Thionyl chloride (SOCl2) is a pale yellow liquid chlorinating agent for converting acids to acid chlorides. It is categorized under HTS 2811.19.61 as an other inorganic oxygen compound of sulfur (nonmetal). Excluded from 2812 as non-carbon halide oxide.
Arsine Gas
Arsine (AsH3) is a highly toxic, flammable gas used in microelectronics for doping. As a hydride acid of nonmetal arsenic, it falls under HTS 2811.19.61 per Chapter 28 definitions for inorganic acids. Its classification excludes organo-inorganic forms.
Carbonyl Sulfide
Carbonyl sulfide (COS) is a colorless, poisonous gas used as a pesticide fumigant and chemical intermediate. It is classified in HTS 2811.19.61 as an other inorganic oxygen compound of carbon and sulfur (nonmetals), per Chapter note exclusions from 2853. Distinct from carbon oxysulfide in notes.
Diphosphorus Tetroxide
Diphosphorus tetroxide (P2O4), a white hygroscopic solid, serves as a phosphorylating agent. Under HTS 2811.19.61 as an other inorganic oxygen compound of phosphorus, it avoids 2812 carbon-specific halides. Used in flame retardants.
Germanium Hydride
Germane (GeH4) is a colorless, pyrophoric gas for semiconductor vapor deposition. Classified as an other inorganic acid of nonmetal germanium in HTS 2811.19.61, fitting Chapter 28 for pure hydrides. Excludes doped forms.
Stibine Gas
Stibine (SbH3) is an extremely toxic, unstable gas used in trace analysis. As a hydride of nonmetal antimony, it enters HTS 2811.19.61 under other inorganic acids, per Chapter definitions excluding organometallics. Rare industrial use.
