License Exception BAG authorizes a U.S. citizen or a permanent resident alien leaving the U.S. to export or reexport shotguns with a barrel length 18 inches or over and shotgun shells provided that not more than three shotguns may be taken on any one trip; the shotguns and shotgun shells must be with the person's baggage (may not be mailed) and they must be for the person's exclusive use for legitimate use. See section 740.14(e) of the EAR for specific requirements in the use of BAG.
