They're often called Shabu or yaba. They're mass produced in Tailand and the majority of them end up in Asia or South Africa and some in Australia. There have been a few batches that have made it to the US, but since we already have better quality meth here, there's not much of a market other than to pass them off as E here, though.
If you search on the internet for "thailand" + "methamphetamine", you'll find a few articles about it.
