Yes. For example, SC stamped cigarettes will be required to be stored in a separate area within the warehouse if the distributor uses the advanced stamping method, meaning the cigarettes are stamped upon arrival at the warehouse.
However, if the distributor uses the stamp-to-order method, meaning the cigarettes are not stamped until pulled from stock to fill an order, then the unstamped cigarettes do not have to be stored separately. Once stamped, the cigarettes should be placed on a delivery truck or on the loading dock to be loaded onto a delivery truck.
See
Regulation 117-1600 for more detailed information concerning separate area storage requirements.
