Carbon tetrafluoride (tetrafluoromethane, perfluorocarbon, PFC-14,R14The English name is Carbon Tetrafluoromethane. Carbon tetrafluoride belongs to the fc class substance, which does not damage the ozone layer but has a greenhouse effect; carbon tetrafluoride is a colorless, odorless, odorless, non-combustible and easily compressible gas. Slightly soluble in water. It is highly volatile and is one of the most stable organic compounds. At 900 degrees Celsius, it does not react with steel, nickel, tungsten, and molybdenum. It only decomposes slowly at carbon arc temperature. It is very stable to heat and has chemical properties than carbon tetrachloride. Inactive.
Carbon tetrafluoride (CF4) is currently the largest plasma etching gas in the microelectronic industry. It is widely used in etching thin film materials such as silicon, silicon dioxide, silicon nitride, phosphosilicate glass and tungsten. It is used in surface cleaning of electronic devices, There are also a large number of applications in the production of solar cells, laser technology, cryogenic refrigeration, gas insulation, leak detectors, control of the attitude of space rockets, detergents, lubricants and brake fluids in printed circuit production. Due to its strong chemical stability, CF4 can also be used in metal smelting and plastics industries.
The characteristics and development trends of electronic gases used in today's ultra-large-scale integrated circuits are ultra-pure, ultra-clean, multi-variety and multi-scale. In order to promote the development of their own microelectronic industries, countries have paid more and more attention to the development of special electronic gases production technologies. For now, CF4 has long occupied the etching gas market with its relatively low price, so it has broad development potential.

Regulatory and compliance status (R14 / Tetrafluoromethane (PFC-14))
R14 (Tetrafluoromethane (PFC-14)) has an ODP of 0 and is not an ozone-depleting substance, and therefore is not bound by the Montreal Protocol phase-out schedule; but as a fluorinated greenhouse gas (F-gas, GWP 7390), it is controlled under the Kigali Amendment and the HFC reduction policies of major economies. The following are the regional status as of 2026, for reference in procurement and compliance decisions.
EU
- RegulationF-gas Regulation (EU) 2024/573, in force since 2024-03-11
- HFC quota60% in 2025–28, 30% in 2029–33, 20% in 2034–35, 15% from 2036; HFC fully phased out by 2050
- New equipment restrictionsNew refrigeration/air-conditioning equipment with GWP>150 has been banned for sale in phases since 2022 (commercial refrigeration 2022, standalone equipment 2025, fully by 2030)
- For R14GWP 7390 > 150 — not permitted for new equipment of this type in the EU; servicing or top-up of existing equipment is unaffected
US
- RegulationAmerican Innovation and Manufacturing (AIM) Act (in force since 2020-12-27)
- TargetHFC production and consumption reduced by 85% by 2036
- Quota cap60% in 2024–28, 30% in 2029–33, 20% in 2034–35, 15% from 2036
- For R14Regulated HFC, exchange value accounted by GWP 7390
China
- RegulationKigali Amendment (entered into force for China on 2021-09-15)
- Baseline2024 production/consumption freeze (production 18.53 billion tCO₂e, consumption 9.05 billion tCO₂e)
- Reduction10% reduction by 2029, 30% by 2035, 50% by 2040, 80% by 2045
- For R14Production and use are subject to quota management
- Domestic procurement qualificationHFC-class refrigerants require environmental filing; see the Q&A below (system: new-ods.ozone.org.cn)
Japan
- RegulationAct on Rational Use and Proper Management of Fluorocarbons
- MechanismSets caps based on “weighted-average GWP” for designated products + compliance deadlines (not an all-sector ban)
- Typical capsDomestic air conditioning ≤750 (2018), commercial air conditioning ≤750 (2020), automotive air conditioning ≤150 (2023), condensing/freezing units ≤1500 (2025), cold storage ≤100 (2019)
- For R14GWP 7390 exceeds condensing/refrigeration units (≤1500), residential air conditioners (≤750), commercial air conditioners (≤750), vehicle air conditioners (≤150), cold stores (≤100) — such new equipment must switch to a lower-GWP refrigerant
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 R14: subject to quota constraints, long-term supply restricted and prices trending upward. For the complete list of Parties and groupings, refer to the UNEP Ozone Secretariat (data version 2026.09).
