What is a Bill of Lading?

The Bill of Lading is a Loading Receipt. The word “lading” is an archaic form of “loading”. The bill of lading started out as a receipt issued when a shipment was loaded onto a vesse

It is still used as a receipt at pickup, handed to the seller as proof that the goods were handed over. It is also a receipt that the shipment was handed over in good condition unless a note to the contrary is made on the BOL at pickup.

The Bill of Lading is a Contract of Carriage. The second role a bill of lading plays is as a shipment contract. The terms and conditions of the forwarder arranging the international transit are included on the bill of lading.

Technically, the contract begins when you accept the forwarder’s freight quote but the Contract of Carriage is evidence of that contract, otherwise, why is the shipment being picked up for international transit?

The Bill of Lading is a Document of Title. The third role a BOL plays is as proof of ownership. Technically, the commercial invoice does that.

The buyer and seller select freight terms when putting the deal together. The Incoterm listed on the commercial invoice sets the point during transit when the goods change hands.

Possession is nine-tenths of the law, and possessing the bill of lading has come to be used as proof of ownership. The seller gets it in their hands at pickup. Later on, the buyer will need it for shipment release.

Bill of Lading Tracking. BOL Tracking

If the master bill of lading number is recorded on the BOL, it can also be used for shipment tracking. Other tracking identifiers, like container numbers, are often recorded on the BOL.

Shipping Line

A shipping line is a business that transports cargo aboard ships.

Containerization revolutionized maritime transport starting in the 1970s. "General cargo" includes goods packaged in boxes, cases, pallets, and barrels. When a cargo is carried in more than one mode, it is intermodal or co-modal.

Container Ships

Container ships (sometimes spelled containerships) are cargo ships that carry all of their load in truck-size intermodal containers, in a technique called containerization. They are a common means of commercial intermodal freight transport and now carry most seagoing non-bulk cargo.

Container ships are cargo ships that carry their entire load in truck-size containers, in a technique called containerization. They form a common means of commercial intermodal freight transport. Informally known as "box boats," they carry the majority of the world's dry cargo. Most container ships are propelled by diesel engines, and have crews of between 10 and 30 people. They generally have a large accommodation block at the stern, directly above the engine room.

Container ship capacity is measured in twenty-foot equivalent units (TEU). Typical loads are a mix of 20-foot and 40-foot (2-TEU) ISO-standard containers, with the latter predominant.

Container ships are distinguished into 7 major size categories: small feeder, feeder, feedermax, Panamax, Post-Panamax, New Panamax and ultra-large.

Container ports

Container traffic through a port is often tracked in terms of twenty foot equivalent units or TEU of throughput. As of 2009, the Port of Singapore was the world's busiest container port, with 25,866,000 TEU handled. That year, six of the busiest ten container ports were in the People's Republic of China, with Shanghai in 2nd place, Port of Hong Kong in 3rd, Shenzhen 4th, Guangzhou 6th, Ningbo 8th, and Qingdao 9th. Rounding out the top ten ports were Busan in South Korea at number 5, Dubai in the United Arab Emirates at number 7, and Rotterdam in the Netherlands in the 10th position with 9,743,290 TEU served.

Shipping industry alliances

In an effort to control costs and maximize capacity utilization on ever larger ships, vessel sharing agreements, co-operative agreements and slot-exchanges and have become a growing feature of the maritime container shipping industry.
