Purpose: This calculator allows users to calculate the number of allowances needed to produce and/or import HFCs and HFC blends based on the exchange value of each regulated substance. For blends that contain ozone-depleting substances (ODS) that are not yet phased out (i.e., R-416A), the calculator also provides the number of ODS allowances required.

Instructions: Select an HFC and/or HFC blend from the dropdown list. For each HFC and HFC blend selected, enter the quantity you intend to produce and/or import. Enter your current HFC allowance balance to determine the number of unexpended allowances remaining after producing and/or importing the regulated HFCs. If you intend to produce and/or import an HFC blend that is not found in the dropdown list, use the blend composition calculator below to calculate the quantity of each regulated HFC contained in the blend for entry into the HFC allowance calculator.

Disclaimer: This tool is for informational purposes to assist potential HFC producers, importers, and exporters. Anyone producing or importing HFCs is responsible for ensuring they have sufficient allowances to import or produce HFCs.

Key: In the Excel version, you enter data in yellow-shaded cells and white cells auto-populate. In this web tool, all input fields are editable where you type, while calculated fields are read-only and appear darker.
