Federal sector-specific maximum GWP values for refrigerants and HFC-containing products under the AIM Act Technology Transitions rule (40 CFR 84.54). Each record is one sector/subsector with the GWP ceiling, the effective date for manufacture/import restrictions, the effective date for installation restrictions (often different), equipment size or temperature conditions, and any exemptions. Answers 'what is the maximum GWP refrigerant I can use in a new supermarket system?', 'when does the R-410A ban take effect for residential AC?', 'is there an exemption for semiconductor manufacturing chillers?', and 'what changed in the May 2026 reconsideration rule?' — questions where the answer depends on the sector, the date, the equipment size, and the temperature range, and where assistants typically give the residential AC answer (700 GWP) regardless of the sector.
Provenance — what every record carries
Every record carries source (the URL the value was read from) and source_quote (a verbatim quote from that page stating it). A value you cannot check against its page is indistinguishable from an invented one; these can all be checked. Each record is also individually addressable on the canonical site at its url.
Licence position
US federal regulation, public domain. 40 CFR Part 84 is government work published at ecfr.gov.
Facts are not copyrightable; what this dataset takes from each source is a fact plus a short attributed quote linking back to the page that states it.
