Labeling in bonded warehouses permitted subject to procedural controls and mandatory full examination before ex-bond release. Packaged imported goods covered by labeling rules may be bonded without initial labeling when labelling at ports/CFSs is impracticable; importers must file a Warehousing Bill of Entry, secure an assessing endorsement allowing bonding without labeling, and ensure the Bond Superintendent performs 100% physical examination and endorses compliance at ex-bonding. Labeling or re-labeling in warehouse, including retail price declaration, is treated as manufacturing and is subject to the regulations governing manufacture and other operations in warehouse.
