How is it imported legally? The EPA's website says otherwise.

But we're still not running out. The stuff is being imported (legally or otherwise) and plenty exists. Sure, it's more expensive than 134a right now, but once 134a is banned, that won't last long.

People in northern climates can get by with 134a in the old systems. Floridians really shouldn't try it.

One more thing. It's easier to get the 609 license than a sales-tax letter. And then you aren't evading taxes.
