Key Pointers
- EPA locks in 2027 HFC supply at 60% of baseline: National caps of 229.5 million MTEVe (production) and 181.5 million MTEVe (consumption) set the refrigerant budget for 2027 under the AIM Act phase-down.
- Compliance pressure ramps up on importers: EPA withheld and revoked 2027 allowances from entities that missed audits or imported HFCs without expending the required allowances, signaling tighter enforcement.
- Critical uses get protected access via ASAs: Around 13.84 million MTEVe in application-specific allowances go to MDIs, semiconductors, marine/trailer foam, and mission-critical military uses, with the Department of Defense receiving the largest single allocation.
What the EPA has decided for 2027
The United States Environmental Protection Agency (EPA) has issued the 2027 calendar-year allowances for producing and consuming hydrofluorocarbons (HFCs) under the American Innovation and Manufacturing (AIM) Act 2020, setting national caps of 229,521,263 metric tons of exchange-value equivalent (MTEVe) for production and 181,522,990 MTEVe for consumption.
Under the AIM Act, the EPA must determine by October 1 each year how many HFC production and consumption allowances may be used in the following calendar year; the 2027 totals lock in the supply of regulated refrigerants for imports and production occurring between January 1 and December 31, 2027.
These caps reflect the 60%-of-baseline step of the AIM Act phasedown schedule for 2024–2028. Allowances may be traded or conferred between entities but cannot be banked into future years.
The notice allocates these allowances across producers, importers, and application-specific end users and applies administrative consequences that withhold or revoke portions of some entities’ allowances for non-compliance.
2027 General pool allowances
| Pool | Key Recipients | What the Pool Covers |
|---|---|---|
| Production Allowances |
|
Rights to produce bulk HFCs in the U.S. in 2027, subject to the national statutory production cap of 229,521,263 MTEVe. |
| Consumption Allowances |
Also includes smaller distributors, certified reclaimers, and industrial end users. |
Rights to import or place bulk HFCs into the U.S. market in 2027, subject to the national statutory consumption cap of 181,522,990 MTEVe. |

Application-specific allowances (ASAs)
For 2027, EPA set aside 13.84 million MTEVe in application-specific allowances (ASAs) for uses where alternatives are not yet fully viable.
| Application | Example recipient | 2027 allocation (MTEVe) |
|---|---|---|
| Mission-critical military end uses | U.S. Department of Defense | 9,070,115.2 |
| Propellants in metered-dose inhalers (MDIs) | Kindeva Drug Delivery | 1,542,817.3 |
| Invagen Pharmaceuticals | 624,808.8 | |
| GlaxoSmithKline (GSK) | 351,567.8 | |
| Armstrong Pharmaceuticals | 200,085.6 | |
| Semiconductor manufacturing | Intel | 656,440.7 |
| Samsung Austin | 276,139.7 | |
| TSMC Arizona | 241,143.5 | |
| Texas Instruments | 208,998.1 | |
| Micron | 168,032.3 | |
| GlobalFoundries | 151,208.2 | |
| Structural composite preformed polyurethane foam (marine and trailer use) | Compsys | 13,585.0 |
These ASAs go directly to end users, who may pass them up the supply chain to producers or importers without the 5% transfer offset that applies to general allowances.
MDI set-aside
The EPA has set aside 1,000,000 MTEVe from both the production and consumption pools to cover unforeseen HFC needs for MDIs arising from a pandemic or other public-health emergency.
Entities using HFCs as MDI propellants may apply for these allowances until April 30, 2027; any unused portion will be redistributed pro rata to general pool holders after that date.
Separately, under the 2025 Application-specific Allowance Review and Renewal Rule, Iofina Chemical receives 3,000 MTEVe per year in production-for-export allowances for specified semiconductor-related exports for 2026–2030, carved out before general production allowances are issued.

Administrative consequences: who lost allowances and why
Separate from the allocation itself, EPA used this notice to publish final actions that adjust 2027 allowances for certain entities under 40 CFR § 84.35.
The EPA withheld portions of allowances from two ASA holders because they failed to submit required audit reports. For example, the EPA withheld 2,291.3 MTEVe from semiconductor manufacturer Wolfspeed until it verified the missing audit.
The EPA also revoked over 1.1 million MTEVe from importers FluoroFusion Specialty Chemicals and Solstice Advanced Materials US, which brought regulated HFCs into the U.S.
After accounting for all administrative consequences, some entities such as Bluon and Resonac America show 0.0 MTEVe available in 2027 because prior-year actions continue to retire or revoke their allowances.
How this fits into the AIM Act phasedown
The 2027 allocation is one annual step in the AIM Act’s long-term trajectory to reduce U.S. HFC production and consumption by 85% below baseline by 2036 as per the 2017 Kigali Amendment. The statute directs the EPA to:
- Phase down production and consumption via an allowance allocation and trading program;
- Maximize reclamation and minimize releases from equipment; and
- Facilitate technology transitions through sector-based restrictions on high-global warming potential (GWP) HFCs.
The 2024–2028 phase of the schedule holds caps at 60% of baseline (~181.5 million MTEVe consumption, 229.5 million MTEVe production). Further step-downs to 30%, 20% and finally 15% of baseline are scheduled for 2029–2033, 2034–2035 and 2036 onward, respectively.
Application-specific allowances ensure continuity in uses where EPA has determined alternatives are not yet fully viable, including MDIs, certain semiconductor processes, marine and trailer foams, mission-critical military uses, and aerospace fire suppression.
Market context and potential implications
The allowance system won’t directly set prices or guarantee shortages, but it does push behavior across the refrigerant chain. A few things to watch:
- Tighter caps over time should make allowances more valuable, improving the economics of reclaiming, recovering, and squeezing more out of existing HFC stocks.
- Enforcement bites. Revoking or withholding allowances from importers that mess up sends a clear signal: compliance matters, and players with cleaner track records could gain ground.
- Application-specific allowances ring-fence supply for critical uses like MDIs and semiconductors, so the general phasedown is less likely to disrupt those sectors, even as they count toward the overall cap.
- Other rules, especially GWP limits on residential and light-commercial AC, commercial refrigeration, and foams, work alongside the allowance program to nudge investment toward lower-GWP refrigerants.
In practice, prices, which refrigerants are available, and how fast equipment switches will depend on inventories, import flows, reclamation volumes, trading, and demand. Not just the headline allowance numbers.
