For the calendar year 2026 allocation of HFC allowances, the EPA withheld a limited number of allowances from all general pool allowance holders. These allowances were set aside to accommodate unforeseen HFC needs for metered dose inhaler (MDI) end users. Entities that use HFCs as a propellant in MDIs had until April 30, 2026, to apply for these allowances, and the EPA received no applications.
