HFC Quotas and the EU F-gas Regulation: The Actual Mechanism, Numbers, and Phase-down Schedule
· HARMONY TECHNOLOGY (ZHEJIANG) CO., LTD.
The short version: HFC regulation operates at two levels simultaneously — the Kigali Amendment to the Montreal Protocol (international consumption phase-down) and the EU F-gas Regulation (EU) 2024/573 (EU market quota). They use the same physical unit of account (tonnes CO₂-equivalent) but have different baselines, different scopes and different compliance points. Confusing the two is the most common technical error in import planning.
1. The Unit of Account: Why Quotas Are Measured in CO₂-equivalent, Not Tonnes
Both regimes express a quantity of HFC as tonnes of CO₂-equivalent:
tCO₂e = mass (tonnes) × GWPWhere GWP comes from matters legally: a refrigerant’s GWP differs between IPCC AR4 and AR5 values, and the regulation specifies which assessment report applies. Quoting “GWP 1430” for R134a is AR4; AR5 gives 1300. Using the wrong report changes the quota arithmetic.
| Refrigerant | GWP (AR4) | GWP (AR5) |
|---|---|---|
| R134a | 1430 | 1300 |
| R410A | 2088 | 1924 |
| R407C | 1774 | 1624 |
| R32 | 675 | 677 |
Technical consequence: 1 tonne of R410A consumes more than twice the quota of 1 tonne of R32. This is the entire intended mechanism — the quota makes low-GWP alternatives economically preferred, mechanically, without a separate subsidy.
2. Kigali Amendment — the International Phase-down
| Element | Provision |
|---|---|
| Adopted | 2016 (Kigali), entered into force 2019 |
| Baseline (developed / Article 2 parties) | Average HFC consumption 2011–2013 + 15 % of the 1989 HCFC baseline |
| Phase-down steps (developed parties) | 90 % of baseline → 2036 target 15 % |
| Unit | tonnes CO₂-equivalent |
The EU’s position under Kigali: in 2024, EU-27 HFC consumption was 60 % below the Montreal Protocol target (recalculated to EU-27 geographic scope) — i.e. the EU is ahead of its international obligation, which is why the binding constraint on EU market participants is the F-gas Regulation quota, not the Kigali schedule.
3. EU F-gas Regulation (EU) 2024/573 — the Operative Instrument
| Element | Provision |
|---|---|
| Legal basis | Regulation (EU) 2024/573 |
| Adopted | 7 February 2024 |
| Applies from | 11 March 2024 |
| Replaces | Regulation (EU) No 517/2014 (repealed in phases, final phase 31 December 2024) |
| Scope (Art. 2, Annexes I–III) | Fluorinated GHGs whether alone or in mixtures; products/equipment containing them |
| Unit | tonnes CO₂-equivalent |
| End point | HFCs phased out in the EU by 2050 |
| Production cap (EU producers) | From 2025: rights equal to 60 % of average annual 2011–2013 production; declining to 15 % by 2036 |
3.1 The quota mechanism
- Placing bulk HFCs on the EU market requires holding a quota.
- Since 2017, HFCs contained in imported RACHP equipment are also inside the quota system — via authorisations that equipment importers obtain from quota holders. This is the provision most often overlooked by exporters: the quota obligation can attach to the equipment, not only to the bulk gas.
- From 2025, HFCs used in metered dose inhalers (MDI) were integrated into the quota system, which is why the 2025 maximum quantity is higher than 2024 — a structural adjustment, not a relaxation (Source: EEA indicator, “Hydrofluorocarbon phase out in Europe”).
- MDI transition rule: the MDI sector is guaranteed full quota corresponding to its most recent market share for 2025–2026, reaching the full reduction rate applied to other sectors only in 2030 (Source: Regulation (EU) 2024/573 recitals).
- Annual reporting: producers, importers and exporters of HFCs must submit annual data via the F-gas Portal (Source: EUR-Lex summary, Regulation (EU) 2024/573).
3.2 Coexisting product bans — a second, independent constraint
Quota limits volume; product bans limit specific applications. Both apply at once:
| Ban | Effective | Source |
|---|---|---|
| Export ban — EU-based operators exporting stationary RACHP equipment and heat pumps charged with high-GWP F-gases out of the EU, where the same equipment cannot be placed on the EU market under Annex IV | From 12 March 2025 | Regulation (EU) 2024/573 (EUR-Lex summary) |
| Domestic split systems < 12 kW: GWP limit 150 | From 2027 | ibid. |
| Small (<12 kW) A/W monoblock heat pumps | GWP limits from 2027, full F-gas ban subsequently | ibid. |
Technical reading — two different provisions, do not merge them: (a) the placing-on-the-market prohibition (Annex IV) is the one that bites on a Chinese supplier — equipment containing a refrigerant above the applicable GWP threshold may not be placed on the EU market from the listed date, whether or not a quota is held; (b) the export ban, in force from 12 March 2025, binds EU-based operators exporting such equipment out of the EU. A Chinese supplier shipping to a non-EU destination is not caught by (b); it is caught by (a) only where the destination is the EU.
4. The Chinese Side — a Different Instrument
China administers HFCs through a domestic quota system for HFC production and consumption, implemented under its Montreal Protocol/Kigali obligations and administered at national level (allocated by province and by enterprise). Technical points an importer needs:
- Chinese HFC quotas are allocated to producers/enterprises, not to exporters as such; a trading company sources from quota-holding producers.
- HFC vs HCFC is a hard distinction: R22 is an HCFC (Montreal Protocol phase-out regime), while R134a/R32/R410A/R407C are HFCs (Kigali phase-down). They are counted in different units and governed by different compliance instruments.
- Quota is consumed at production, so availability can tighten at year-end when annual allocations are exhausted — a scheduling artefact of the quota cycle, not a supply shortage.
The export side of the same system — annual quota, per-shipment approval certificate and export licence, with their filing dates and validity windows — is set out step by step in HS codes and the China export licence chain.
5. Reading a Quota-Related Document Set
| Document | Issued by | What it proves |
|---|---|---|
| Quota authorisation | EU Commission (via F-gas Portal) | The holder may place the stated tCO₂e on the EU market |
| Authorisation from a quota holder | Quota holder → equipment importer | The equipment’s contained HFCs are covered (post-2017 rule) |
| REACH registration | Importer or Only Representative | Separate obligation; not satisfied by an F-gas quota |
| Declaration of conformity | Equipment manufacturer | Product complies with the applicable ban/GWP limit |
Failure modes to check for: treating a REACH registration as an F-gas quota (they are different obligations with different legal bases); assuming the bulk-gas quota covers equipment-embedded gas; using AR5 GWP values in a calculation that the regulation defines by AR4.

Industry compilation (Danfoss F-gas timeline) is cited only for the product-ban dates and is marked as such. Numerical values should be verified against the applicable regulation for the year of shipment; quota maxima are published annually and change.
FAQ
Why are HFC quotas measured in CO₂-equivalent rather than tonnes? The unit is tCO₂e = mass × GWP, which makes low-GWP alternatives economically preferred mechanically. Note the regulation specifies which IPCC assessment report applies — AR4 and AR5 values differ (R134a: 1430 vs 1300).
Does the quota apply to equipment as well as bulk gas? Yes. Since 2017, HFCs contained in imported RACHP equipment are inside the quota system through authorisations that equipment importers obtain from quota holders.
Which regulation currently applies in the EU? Regulation (EU) 2024/573, adopted 7 February 2024 and applying from 11 March 2024, replacing Regulation (EU) No 517/2014. It targets an HFC phase-out in the EU by 2050.
What we can provide
For quota-governed products we can state the regime an offer sits under, per shipment and per quota year:
- Regime identification — whether the product is an HFC (Kigali phase-down, and an EU F-gas quota for that market) or an HCFC (Montreal phase-out): which instrument governs it, and in which unit it is counted (tonnes of substance, or tonnes CO₂-equivalent).
- GWP basis — the GWP value used in any quota arithmetic, with the assessment report (AR4 / AR5 / AR6) named, since each regime defines which report applies.
- The Chinese export chain — the annual quota, the per-shipment approval certificate and the export licence that apply to the current quota year, with the filing dates and validity windows that constrain the shipping schedule.
- Licence lead time — the route a given shipment moves under and how long it takes to paper, so the licensing window is planned into the schedule rather than discovered at the port.
