Olivier,

If Mike's words are not enough,here is a story for you.
A little over two years ago, I tried to buys ome Nepenthes from a guy in Malaysia. I had just received my import permit, but the USDA forgot my stickers and was awaiting them to mail those. Anyway, the person on the other end decided to mail the plants and labled them as "children's toys," to avoid his end of paperwork. Beagles sniffed out the plants and the USDA visited me. I told them the truth on what happened, but I still got a letter notifying me I was being fined for $2500!!! Even though I had obtained the paperwork on my end, I was at fault for ordering the plants. The USDA considered me a smuggler.
Anyway, hope that helps.

Cheers,

Joe
