There may be an easy answer to my question not that I am involved too much nowadays but I can remember the days of r502/r22 phase out,when the price of refrigerant is hiked as r404a is at the present time where does the hiked price go to? it's still in stock at wholesalers prior to the hike so production costs don't come into play does it go to the wholesalers profit or does the government get the extra payment it seems a grey area to me or am I missing the obvious?.
