As are most of the CFCs. From memory India has a good bit of CFC production also. I mean, why wouldn't you? They're mature technology, easy to make and pretty much ideal in their use.
Halon hasn't been replaced in aircraft because there's still no replacement that ticks all the boxes. I still remember all the BCF extinguishers we had dotted around the boats over the years and was highly unimpressed when we had to trade those in for dry powder.
