Will history repeat? TTB stopped processing applications during mid-90s government shutdown
We can see what happened in 1995 and 1996, the last two times the federal government actually shut down for a few weeks. […] The Bureau of Alcohol, Tobacco, and Firearms stopped processing applications for firearms and alcohol.
The TTB processes at the federal level, among many other things, manufacturing licenses and alcohol labels required for sales beyond state borders.
