Is R-134a being phased out in India?
The environmental track
R-134a has zero ozone depletion potential, so it has no Montreal Protocol phase-out. Its GWP is about 1,430 on IPCC AR4, which puts it under the Kigali phase-down alongside every other HFC.
India freezes HFC consumption in 2028 and steps down to 15% of baseline by 2047. Because quota is counted in CO₂-equivalent, R-134a sits in the middle of the pack: lower than R-404A or R-410A, higher than R-32. It will tighten, but later and more gently than the high-GWP fluids.
The automotive track, which is separate
In Europe the MAC Directive forced new vehicle air conditioning off R-134a and onto R-1234yf. That is a European regulation and it does not apply in India. Indian vehicle air conditioning remains overwhelmingly R-134a, with R-1234yf appearing on newer higher-end and export-specification platforms because the manufacturer designed the vehicle globally.
So the automotive shift you may have read about is real, but it is happening to new vehicles by manufacturer design, not to your existing fleet by regulation.
The anti-dumping duty
This is the change most buyers actually feel, and it has nothing to do with the environment. A definitive anti-dumping duty on R-134a originating in or exported from China took effect on 24 December 2025 for five years, following a Directorate General of Trade Remedies investigation.
Anti-dumping duty is levied against a specific tariff line and a specific origin. It raises the landed cost of imported Chinese material and it does not apply to domestic production. The anti-dumping guide covers the detail.
What this means in practice
R-134a continues to be available for chillers, automotive air conditioning, appliances and process cooling. Price is influenced more by the duty and the exchange rate than by Kigali at this stage. There is no reason to convert equipment, and for centrifugal chillers in particular there is often no practical alternative short of replacing the machine.
Where a lower-GWP route matters, R-1234ze is the HFO used in new commercial chillers and heat pumps. It is designed in, not retrofitted.
Quick answers
Is R-134a banned in India?
No. It is legal to buy, use and service with no end date. It phases down by quota under Kigali from 2028 alongside other HFCs.
Why has R-134a become more expensive?
Mainly the anti-dumping duty on Chinese imports that took effect on 24 December 2025 for five years, plus the exchange rate. That is a trade measure, not an environmental one.
Do Indian cars have to move off R-134a?
No. The European MAC Directive that forced that change does not apply in India. R-1234yf appears on newer higher-end and export-specification platforms by manufacturer design.
What replaces R-134a in chillers?
R-1234ze in new low-GWP machines. It is designed into the equipment rather than retrofitted into an existing R-134a chiller.
