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.

Import Tips & Compliance
• Confirm the balance gas (e.g
• nitrogen) is inert and the dilution is solely for safety or transport, not for a specific analytical application
• Provide the exact concentration and cylinder specifications to CBSA
• Verify if the product requires a Canadian Environmental Protection Act permit due to HFC-23 content
