Tariffs may be amended by the licensed warehouseman by filing a new tariff with the Department. The previous tariff continues to apply on all commodities received prior to the effective date of the amended tariff until the anniversary date of deposit. The amended tariff applies to any commodities received after the effective date of the amendment and on any commodities stored under the previous tariff commencing on the anniversary date of the storage period.
