What does cy/cy mean on a bill of lading?

Bill of lading, which is a transport document evidences receipt of cargo, contract of carriage and represents title of goods, is mostly used in international port-to-port sea shipments.

A bill of lading should normally state the port of loading and port of discharge.

Port of loading is the place where the goods are shipped on board a vessel. Port of discharge is the place where the vessel is off-loaded and the goods are distributed to their respective consignees.

Some bills of lading contain "cy/cy" term in addition to port of loading and port of discharge.

Today I would like to explain the meaning of "cy/cy" term as seen on the bills of lading.
