Package marking requirement mandates durable stencil numbering; unmarked exports barred from examination and shipping bill registration. Export consignments must be durably stencil marked and serially numbered to show the total packages covered by the shipping bill; carting permission, an exporter-signed checklist, and custodian endorsement of quantities are required for entry to the export shed. Customs will register shipping bills and permit examination only after the full consignment is received with proper marking and numbering, and unmarked packages will not be examined. Non-compliance by exporters, CHAs or CFSs will lead to appropriate legal action.
