Onestep- Actually, the EPA allows (last time I checked) for anyone who holds a resale license
, to buy and resell refrigerant gasses with no license
necessary. Normally, anyone with a business in any state will have a resale (sales tax) license, and that's all it takes to buy a carload of R12 or anything else.
Now in theory, they've also got to RESELL it again. But in practice? Ah, there's no one checking on that. And with internet
sellers (who sometimes sell real goods, other times not) who's going to check that my 20 year old Passaic NJ resale license is real? Once they've got what looks real, they're off the hook.
