Well, that's something, you know, especially on the containers. On the bulk side, you know pretty much what you have in your ships' holds because very often you have surveyors, for example, when the things are put in the holds and you may have some testing or whatever. But when it's in containers you rely on what the shippers said and you rely on the documentation that the shipper provides, because they are the ones who put the things in the containers and seal the containers. After that you basically have to trust the information you have received.
