R13 refrigerant is also alias R-13, Freon 13, F13, F-13, CFC13, CFC-13, trifluorochloromethane. The trade names include Freon 13, etc., the Chinese name trifluoro-chloromethane, the English name Chlorotrifluoromethane, and the chemical formula CClF3. Since R13 belongs to the CFC class (the first batch of restricted ODS substances, Class I Ozone-deploying Substances), which is harmful to the ozone layer and has a greenhouse effect, in developed and some developing countries, initial installation on new refrigeration equipment or re-addition on old equipment has been stopped; China stopped the production of R13 refrigerant and initial installation on new refrigeration and air-conditioning equipment in 2007.
As a widely used cryogenic refrigerant, R13 is mainly used in cryogenic equipment such as ultra-low temperature refrigerators or freezers, blood bank refrigerators, freezers/freeze dryers, environmental test chambers/equipment (cold and hot shock testers), biochemical test chambers, etc.(including scientific refrigeration, medical refrigeration, etc.), and is mostly used in the low temperature section of these cascade refrigeration systems. Trifluoro-monochloromethane can also be used as a fire extinguishing agent. withR22The composed refrigeration system is used for ultra-low temperature refrigeration devices at-80~-120℃. It is also used as a blowing agent in foam plastics.

R13 Packaging Specifications
Reusable high-pressure steel cylinder packaging (need to recycle packaging steel cylinders): 6kg/bottle, 35kg/bottle.
R13 Storage and transportation
R13 refrigerant cylinders are high-pressure containers. When stored, they should be kept away from fire, heat sources, and avoid direct exposure to the sun. They should be stored in a cool, dry and ventilated warehouse; they should be loaded and unloaded lightly during handling to prevent cylinders, valves and other accessories from being damaged.

Regulatory and compliance status (R13 / Chlorotrifluoromethane (CFC-13)) — fully phased out
R13 (Chlorotrifluoromethane (CFC-13)) 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 R13Not 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 R13Only reclaimed product may be used for existing equipment; no new production/import permitted
China

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 R13: 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).
