Detailed rules governing the forwarding agent's liability to the customer, as well as grounds and limitations of such liability, are fixed by the parties in the contract of freight forwarding.
The required documents are issued by the carrier directly or through integrated forwarding agents, and they include information about booking, current position of the shipment, and status of delivery.
Under this model, traditional carriers diversify their activities by creating a forwarding unit within their companies, or forwarding agents acquire vehicles or create dependent carriers.
