The larger and heavier your vehicle is, the more expensive the overseas vehicle shipping will be. Larger vehicles take up more room on the cargo ship, which reduces the total number of vehicles that can be loaded for overseas shipping. When there are fewer vehicles loaded, the carrier generates less profit. To account for this, larger vehicles are quoted at a higher rate.
If you choose to ship your vehicle in a container, your cost to ship a car overseas will increase with the shipping container’s increasing size. While containers come in a wide variety of sizes, 20 and 40 foot lengths are the most popular. There are also 40-foot high cubes that are taller than the standard container size.
The heavier your vehicle is, the more effort and time it takes to move that weight. This means more fuel gets used. International shipping companies account for this by increasing the shipment quote.
