A gateway rate is a transportation rate that is applied to goods that are moving through a specific gateway or point of entry. For example, it's the rate for transportation of goods from the port of origin to the destination country, or from the airport to the destination city. This rate is used to cover the cost of moving the goods from one point to another, and can include costs such as loading and unloading fees, customs clearance fees, and other related expenses. Gateway rates can vary depending on the location and mode of transportation, and are usually determined by the carrier or logistics company providing the service. They are also known as a "port-to-port" or "airport-to-airport" rates.
