If beer is to be packaged in cases of sizes other than those shown above, the beer manufacturer shall notify the board in advance and request to be advised of the proper fractional barrel equivalent of the proposed container.
Reports of inventories required to be made on each tax return shall be in agreement with Federal Form TTB F 5130.9.
