Hi Sibylle and welcome to the forum,
Some good advice from everyone above, but especially from Robb. You really do need to be speaking with the right people to be getting the best possible advice on this one. I don't know what sort of volume you're thinking about importing, but have you got a US distribution avenue in mind or will you be distributing yourself?
What size shipment do you have in mind exactly, are we speaking a 40 foot container load here of a few cartons air freighted into the US?
Your question kind of leaves me with far more questions than actual answers unfortunately. Things like, is this a new formula not yet on the market, something you're having made?
Cheers
