Do you happen to have the source? I always thought that the destination of the commodities stayed constant, and that it was the burden of the final buyer/commodity holder to organize shipping logistics once it arrived at port.

Not one I can easily point you to - my in-laws' neighbour apparently used to be an engineer on board such ships. It's possible this is no longer accurate as this would have presumably been some decades ago.
