FDA and getting drinks into Taiwan

Hi all,
I got a bit homesick :aiyo: and decided to get some of my favorite soda from sent to me (at great expense), 24 cans of 330ml. But now they have been stopped :fume: at customs/FDA because they are over 6Kg and are wanting some other paperwork(they thought it was medicine :loco: instead of soda.) Has anyone got any experience of dealing with the FDA?
