Guess it is a little too late, but if you don't know a single thing about customs and import regulations of your ton,you should not be messing about without educating yourself.
Does it have any import duties or taxes on it?Imagine going down to pick it up and you owe $50,000.Perhaps it is legal in small amounts but illegal in large amounts:then all these polite gentlemen ask you all sorts of questions,perhaps locking you up.Then all your evil plans are shot.
Since you are posting here on the Hive,one might draw the conclusion you are importing sassafrass-in which case it would be very advisable to check your laws before showing up to pick it up.
