Products classified under HTS 2903.11.00.10
Chloromethane (Methyl Chloride) 99% Purity
Chloromethane, also known as methyl chloride, is a colorless, flammable gas used primarily as a chemical intermediate in the production of silicone polymers and agricultural chemicals. This 99% purity grade falls under HTS 2903.11.0010 as a saturated chlorinated derivative of acyclic hydrocarbons, specifically chloromethane. It is supplied in pressurized cylinders for industrial use.
Methyl Chloride Refrigerant Grade R-40
Methyl chloride R-40 is a historical refrigerant gas, still used in specialty low-temperature applications and as a methylating agent. Classified under HTS 2903.11.0010 as pure chloromethane, a halogenated acyclic hydrocarbon derivative. Supplied in 50 lb cylinders with refrigerant-grade purity.
Chloromethane Anhydrous Industrial Grade
Anhydrous chloromethane is used in the production of methyl cellulose, quaternary ammonium compounds, and as a solvent in organic synthesis. This industrial grade meets HTS 2903.11.0010 specifications as chemically defined chloromethane without water impurities. Typically shipped in ton cylinders.
Methyl Chloride Pharmaceutical Grade USP
USP-grade methyl chloride meets pharmaceutical standards for use in sterile alkylation reactions and as a propellant in metered-dose inhalers. Falls under HTS 2903.11.0010 as chemically pure chloromethane. Supplied in small medical gas cylinders.
Chloromethane Silicone Monomer Precursor
High-purity chloromethane serves as the methylating agent in the direct process for producing dimethyldichlorosilane, the primary silicone monomer. Classified under HTS 2903.11.0010 as it is chemically defined chloromethane used in organosilicon synthesis. Ultra-high purity minimizes side reactions.
Methyl Chloride Agrochemical Intermediate
Chloromethane is reacted with alcohols to produce methyl esters used in herbicide and insecticide synthesis. This agrochem grade meets HTS 2903.11.0010 as pure chloromethane, the saturated chlorinated acyclic hydrocarbon. Supplied in ISO tank containers.
Electronic Grade Chloromethane 99.999%
Ultra-high purity (6N) chloromethane used in vapor phase epitaxial growth of compound semiconductors and as a dopant source. Meets stringent HTS 2903.11.0010 classification as chemically defined chloromethane for electronics manufacturing. Lecker-free cylinders.
Chloromethane Extractive Distillation Solvent
Methyl chloride serves as a selective solvent in extractive distillation for separating close-boiling hydrocarbons like aromatics from paraffins. Recovered and purified to HTS 2903.11.0010 specifications as chemically defined chloromethane. Continuous process grade.
Methyl Chloride Rubber Accelerator Precursor
Chloromethane reacts with aromatic amines to produce rubber vulcanization accelerators like MBT and CBS. Meets HTS 2903.11.0010 as pure chloromethane for synthetic rubber industry. Drum quantities.
Chloromethane Aerosol Propellant
Methyl chloride functions as a low-pressure aerosol propellant for specialty products like pet care sprays and industrial cleaners. Purified to HTS 2903.11.0010 standards as chemically defined chloromethane. Non-flammable when blended.
