The Bill of Lading is a crucial document that serves three functions: receipt for shipped goods, contract of carriage, and document of title. Understanding it is essential for exporters.

Evidence that carrier received goods in stated condition and quantity
Defines the terms of carriage between shipper and carrier
Document of title - holder can claim goods (if negotiable)
Document of title for sea freight. Can be negotiable (to order) or non-negotiable (straight).
Best for: Sea shipments, especially with L/C payment
Air cargo transport document. Always non-negotiable - consignee can collect on arrival.
Best for: Air freight, time-sensitive shipments
Covers transportation by multiple modes (sea + road, rail, etc.).
Best for: Door-to-door shipments using multiple carriers
Road transport document, typically non-negotiable.
Best for: Land transport, regional trade
In modern practice, original B/Ls can be "surrendered" at origin port, and goods released at destination without presenting physical documents. This is called Telex Release or Sea Waybill. Useful for trusted buyers, but reduces security for sellers.
