HFC-23 Semiconductor Etch Gas
Ultra-high purity trifluoromethane (HFC-23) for semiconductor plasma etching is a separate chemically defined organic compound. It is a saturated fluorinated derivative of acyclic hydrocarbons, classified under tariff item 2903.41.00. The high purity grade does not change the chemical classification.
Medical-Grade HFC-23 Calibration Gas
Medical-grade HFC-23 calibration gas is high-purity trifluoromethane diluted in a balance gas for analytical calibration. While the diluted form is not a pure compound, the HFC-23 component itself is a saturated fluorinated derivative of acyclic hydrocarbons. The product is classifiable under tariff item 2903.41.00 if the dilution is for safety or transport and does not render it suitable for a specific use.
