U.S. District Judge Emmet G. Sullivan on Thursday also ordered Xun Wang to pay a $100,000 fine and perform 500 hours of community service.
Wang, a former managing director of PPG Paints Trading Co. of Shanghai, admitted helping send three shipments of high-performance epoxy coatings from the U.S. to Pakistan through China without the required export license.
She pleaded guilty in November 2011. As part of the plea, Wang agreed to cooperate with the government's investigation.
The Justice Department says her cooperation led to this month's guilty plea by the China Nuclear Industry Huaxing (Wa-ZING) Construction Co. for conspiring to violate nuclear export restrictions on Pakistan.
