For a truck yeah, but across the ocean, it isn't quite that simple because GPUs and grains are sent in different types of ships (or different modes entirely) that aren't interchangeable.
You're right - perishable goods have to be shipped fast. Your bananas, berries, fresh fish, and not-fron-concentrate juice can't be on some slow-steaming container ship with the furniture, clothes, building materials and vehicles.

The GPUs can though.
