HFC-23 Medical Aerosol Propellant Blend
This is a pharmaceutical-grade propellant blend containing trifluoromethane (HFC-23) used in metered-dose inhalers and nasal sprays. It falls under tariff item 3827.59.00 because it is a mixture containing a halogenated derivative of methane (HFC-23) that does not contain chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs). The product meets USP standards for medical applications and is not a separate chemically defined compound, which would be excluded from Chapter 38.
