R11(CFC-11, monofluorotrichloromethane) was widely used in the early days and was mainly used in refrigeration equipment such as large central air conditioners (centrifugal chillers). Monofluorotrichloromethane is also widely used in polyurethane (PU) rigid foams as blowing agents, extractants, solvents, and dry cleaning agents. It can also be used as a sequencing agent and an air-soluble insecticide propellant. A pulsed time domain reflection level gauge can also be used for level measurement.
R11 refrigerant is a colorless liquid that is soluble in ethanol and ether, and slightly soluble in water. It is non-combustible and odorless. R11 refrigerant belongs to the CFC class (the first batch of restricted ODS substance Class I Ozone-depleting Substances)-it is harmful to the ozone layer and has a greenhouse effect. Therefore, in developed countries and some developing countries, initial installation on new air conditioners and refrigeration equipment or re-addition on old equipment has been stopped; China stopped production of R11 refrigerant and initial installation on new refrigeration and air-conditioning equipment in 2007.

Regulatory and compliance status (R11 / Trichlorofluoromethane (CFC-11)) — fully phased out
R11 (Trichlorofluoromethane (CFC-11)) belongs to the chlorofluorocarbons (CFC), with an ODP of 1.0, and is a Class I controlled substance under the Montreal Protocol. Production and consumption have been fully halted worldwide, with presence only in very few exempted uses (e.g. essential-use exemptions, feedstock uses) and in the recovery and reclamation sector. The following are the regional status as of 2026.
EU
- RegulationOzone-Depleting Substances Regulation (EC) 1005/2009
- StatusProduction, placing on the market and use fully prohibited
- ExemptionsOnly essential uses (e.g. metered-dose inhalers), feedstock and laboratory uses may apply for exemption
- For R11Not permitted for new installations or servicing top-up; equipment must be retrofitted or replaced with alternative refrigerants
US
- RegulationClean Air Act Title VI + SNAP program
- StatusClass I substance, production and import halted since 1996
- Existing stockOnly reclaimed refrigerant is permitted for the maintenance of existing stock equipment
- For R11Only reclaimed product may be used for existing equipment; no new production/import permitted
China
- RegulationRegulations on the Administration of Ozone-Depleting Substances (2024 revision)
- StatusCFC class fully phased out; production and use prohibited
- Existing stockReclaimed refrigerant may circulate within the filing and registration system
- For R11No legal supply of virgin product; equipment must be retrofitted or decommissioned
Japan
- RegulationOzone Layer Protection Act + Act on Rational Use and Proper Management of Fluorocarbons
- StatusSpecific fluorocarbons (CFC) fully abolished
- Existing stockReclaimed refrigerant limited to existing equipment
- For R11No 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 R11: globally phased out, no legal supply of virgin product. For the complete list of Parties and groupings, refer to the UNEP Ozone Secretariat (data version 2026.09).
