How much longer can R22 be used? Is it cost-effective to buy now?

R22 (Chlorodifluoromethane (HCFC-22)) belongs to the hydrochlorofluorocarbons (HCFC), with an ODP of 0.055, and is a Class II controlled substance under the Montreal Protocol, currently in the process of global phase-out. Developed countries halted the production and import of virgin HCFC on 2020-01-01; China, under its National Phase-out Plan, reduces the baseline by 67.5% in 2025 and 97.5% in 2030, retaining only a minimal amount for servicing use after 2040. The EU (EC) 1005/2009, the US Clean Air Act Title VI and Japan's Ozone Layer Protection Act all permit only reclaimed product for the maintenance of existing equipment. Therefore: R22 can no longer be used in new equipment; reclaimed product remains available for servicing existing equipment, but supply tightens year by year and prices rise. It is recommended to select an alternative refrigerant directly for new projects (R32, R410A, R407C, R454B or hydrocarbon R290), and to plan retrofits for existing equipment in advance (noting mineral oil (not interchangeable with POE used by R407C/R410A) and system compatibility).

Does purchasing R22 in China require environmental filing?

Yes. R22 is a controlled HCFC (ODP 0.055) and is subject to quota licensing and filing management in China. The purchaser must be an enterprise filed in the Ozone-Depleting Substances Information Management System (new-ods.ozone.org.cn), and the seller must verify the purchaser's filing and retain sales and purchase records. As the 97.5% reduction schedule by 2030 progresses, servicing quotas will be prioritised for existing equipment, and supply and price pressures will continue to rise.

Comus (DuPont) R22 refrigerant.

R22 refrigerant, also known as R-22, difluoro-chloromethane, Freon 22, F-22, HCFC-22.

R22 refrigerant is used in reciprocating compressors and is used in household air conditioners, central air conditioners, mobile air conditioners, heat pump water heaters, dehumidifiers, freezing dryers, cold storage, food refrigeration equipment, marine refrigeration equipment, industrial refrigeration, commercial refrigeration, freezing condensation units, supermarket display cabinets and other refrigeration equipment; R22 is also widely used as a raw material for polytetrafluoroethylene resin and an intermediate for the gas extinguishing agent R1211, as well as for polymer (plastic) physicsblowing agent。It can also be used as aerosol propellants for pesticides and spray paint. It is a basic raw material for the production of various fluorine-containing polymer compounds.

Alternatives & Matched Lubricant

Under the Kigali Amendment HFC phase-down, the following alternatives can be evaluated (R22 itself remains legal to use); the final selection must match the application, system pressure and lubricant compatibility.

Alternative refrigerants: R32, R410A, R407C, R454B or hydrocarbon R290
Matched lubricant: mineral oil (not interchangeable with POE used by R407C/R410A)

Alternatives are a selection reference only; the equipment manufacturer's requirements and local regulations prevail.

GWP comparison: R22 vs. alternatives

Side-by-side comparison of R22 and its alternative refrigerants on the IPCC AR4 (GWP100) basis.

Regulatory and compliance status (R22 / Chlorodifluoromethane (HCFC-22)) — phase-out in progress

R22 (Chlorodifluoromethane (HCFC-22)) belongs to the hydrochlorofluorocarbons (HCFC), with an ODP of 0.055, and is a Class II controlled substance under the Montreal Protocol, currently subject to the global phase-out schedule. Developed countries halted production and import in 2020; developing countries (including China) are advancing according to the schedule, with servicing stock tightening year by year. The following are the regional status as of 2026.

EU

RegulationOzone-Depleting Substances Regulation (EC) 1005/2009
StatusVirgin HCFC no longer placed on the market
ServicingUse of reclaimed product permitted until 2030 (for some equipment types)

US

RegulationClean Air Act Title VI + SNAP program
StatusProduction and import of virgin HCFC halted from 2020-01-01
Existing stockReclaimed product can be used for the maintenance of existing equipment
For R22Only reclaimed product available; supply and prices continue to tighten

China

RegulationRegulations on the Administration of Ozone-Depleting Substances (2024 revision) + National Phase-out Plan
Schedule67.5% baseline reduction by 2025, 97.5% by 2030, with only a minimal amount retained for servicing use after 2040
QuotaAnnual quota licensing for production and use, decreasing year by year
For R22Supplied within quota; procurement must be filed; servicing use given priority
Domestic procurement qualificationMust be filed in the “Ozone-Depleting Substances Information Management System”; suppliers must verify the filing

Japan

RegulationOzone Layer Protection Act + Act on Rational Use and Proper Management of Fluorocarbons
StatusHCFC is essentially abolished, with only reclaimed product in circulation
For R22No supply of virgin product; must be retrofitted or replaced

Other countries and regions (grouped by the Kigali Amendment)

Apart from the four columns of EU / US / China / Japan, the global 170+ Kigali parties all comply under the A5 (developing countries) / non-A5 (developed countries) groupings of the Montreal Protocol, and none impose equipment-level bans. The grouping determines the HFC reduction pace and is unrelated to geography — for example, the Middle East Gulf and India belong to A5 Group 2, while Brazil, Mexico and Chile belong to A5 Group 1 (same group as China). The table below is a quick reference for the groupings of major markets:

Grouping	HFC reduction pace	Major countries / regions (representative)
A5 Group 1 (developing countries, including China)	2024 freeze → 10% reduction by 2029 → 30% by 2035 → 50% by 2040 → 80% by 2045	Brazil, Argentina, Chile, Colombia, Peru, Mexico, South Africa, South Korea, Thailand, Indonesia, Malaysia, Vietnam, Egypt, Nigeria, etc. (about 140 countries in total)
A5 Group 2 (high-ambient-temperature group, HAT)	2028 freeze → 10% reduction by 2032 → 20% by 2037 → 30% by 2042 → 85% by 2047	India, Bahrain, Iran, Iraq, Kuwait, Oman, Pakistan, Qatar, Saudi Arabia, United Arab Emirates
Other non-A5 (developed countries, except EU/US/Japan)	85% reduction by 2036 / reduced to 15% by 2050	Canada, Australia, New Zealand, Switzerland, Norway, United Kingdom, Russia* (first two steps delayed: 5% by 2020, 35% by 2025), etc.

For R22: a controlled substance in the phase-out process, with supply tightening year by year and prices rising. For the complete list of Parties and groupings, refer to the UNEP Ozone Secretariat (data version 2026.09).

Buyer conclusion: R22 is an HCFC-class controlled substance with ODP 0.055 and GWP 1810, currently in the global phase-out process, with supply tightening year by year and prices rising, and it can no longer be used in new equipment. Developed countries halted production and import of virgin product in 2020; China, under its National Phase-out Plan, reduces the baseline by 67.5% in 2025 and 97.5% in 2030. The EU, US and Japan all permit only reclaimed product for the maintenance of existing equipment. Recommendation: select an alternative refrigerant directly for new projects (R32, R410A, R407C, R454B or hydrocarbon R290); if existing equipment still uses R22, a retrofit should be planned in advance (noting mineral oil (not interchangeable with POE used by R407C/R410A) and system compatibility). Domestic procurement must be filed in the “Ozone-Depleting Substances Information Management System”.
