Licensing of special warehouses governs storage for duty free, ship, airline and diplomatic stores with transitional licensing requirements. Insertion of Section 58A creates a licensing regime for special warehouses storing dutiable goods for duty free shops, ship stores, airline stores and diplomatic stores; Board notifications and regulations specify eligible end uses. Existing licensees may operate under customs lock during a limited transitional period but must apply under the Special Warehouse Licensing Regulation within the prescribed window to continue storage beyond that period. Duty free shops in customs areas are treated as points of sale, not warehouses; city and airport warehouses that can be customs locked qualify for licensing. Recovery of costs may be by merchant over time or cost recovery as determined locally.
