The convention establishes a modern, comprehensive, uniform legal regime governing the rights and obligations of shippers, carriers and consignees under a contract for door-to-door shipments that involve international sea transport.
Some road transportation is done on regular routes or for only one consignee per run, while others transport goods from many different loading stations/shippers to various consignees.
Instead of selling to middlemen, the company now appointed colonial merchants to receive the tea on consignment; the consignees would in turn sell the tea for a commission.
