36-year-old Shiraz Malik pleaded guilty in October last year of selling pharmaceuticals and highly regulated chemicals to customers in the US, Europe, Mexico, and other countries and conspiring to launder the profits of that activity.
According to court documents, Malik operated out of Warsaw, Poland from June 2008 to September 2011.
He was arrested at the Prague International Airport in September 2011, and was extradited from the Czech Republic to the US in June 2012.
It alleged that the drugs were sent from Pakistan to the customers, and the Malik emailed the tracking numbers to buyers that his accomplices gave him.
Malik sold large quantities of ephedrine to customers in Mexico, the country of origin for most of the methamphetamine sold in the US, the Justice Department said.
"Malik operated an international supermarket for illegal drugs," said US Attorney Benjamin Wagner.
"As the Internet allows everyone access to international markets, federal law enforcement officials will be vigilant in protecting this country from overseas predators who profit off the addiction of others," he said.
"Malik had never set foot in this country before he was arrested and extradited here on these charges," the US Attorney said.
