Warehousing of excisable goods: storage under bond allowed pending export, subject to registration, records and duty obligations. Warehousing permits storage of excisable goods in registered warehouses without immediate duty, subject to prescribed application, invoicing and certification procedures; warehouse-owners must maintain detailed inward/outward registers and are liable for custody, duty, interest and penalties. Export warehousing operates under a general bond with security, CT-2 and ARE forms, and a Running Bond Account; proof of export by customs-attested ARE-1 is required for bond credit, while diversion to home consumption requires payment of duty and interest and appropriate adjustments.
