"This product may require a licence to export from the United States".
this didn't means you will not get them, it is common for all US products.
In case your project is on the "export restriction" list, try another distributor
or a simple trick (depeds of course on volume/cost)
Rent a P.O. box in NA for few bucks, send it over there
and forward to your country, all you need is e.g. a ups customer number.
What kind of idiocy is this?
United States Bushdiocy, some ppl over there already on "idiocracy" level.
