The Alcohol and Tobacco Tax and Trade Bureau (TTB) is addressing petitions requesting that TTB amend the regulations that govern distilled spirits containers to provide for additional authorized standards of fill. Rather than proposing the addition of new authorized sizes, TTB is proposing to eliminate all but minimum and maximum standards of fill for distilled spirits containers in order to provide industry members greater flexibility in production and sourcing of containers, and provide consumers broader purchasing options. This deregulatory action would also eliminate restrictions that are no longer required for tax administration, and that inhibit competition and the movement of goods in domestic and international commerce. TTB is also proposing to amend the labeling regulations for distilled spirits and malt beverages to specifically provide that distilled spirits may be labeled with the equivalent standard United States (U.S.) measure in addition to the mandatory metric measure, and for malt beverages to be labeled with the equivalent metric measure in addition to the mandatory U.S. measure. Such labeling is currently allowed, but that is not explicitly stated in current regulations. This revision will align the distilled spirits and malt beverage labeling regulations with current policy and also with the wine labeling regulations, which state that wine may be labeled with the equivalent standard U.S. measure in addition to the mandatory metric measure.
