What are the characteristics of liner shipping?

Liner refers to a transport ship that calls at a fixed port along a certain route according to the prescribed schedule and rate. Liner shipping is characterized by 1. "Four fixed", that is, fixed routes and ports of call, fixed shipping dates (published in newspapers or sent directly to shippers) and fixed freight rates. 2. The "pipe loading and unloading" of the liner company and related loading and unloading fees have been included in the rate table and collected together, and demurrage and courier fees are not calculated. 3. The contract of carriage and the rights and obligations of both parties are based on the liner bill of lading issued by the shipping company or its agent. 4. The mode of goods transportation is flexible, regardless of the variety and quantity, as long as there is a shipping space, which is more suitable for the transportation of sporadic goods and groceries in international trade. 5. Goods are generally delivered at the dock warehouse designated by the shipping company.
