All Sarracenia are on CITES. The three mentioned above are on CITES I, whereas the rest are on CITES II. Any plant material needs phytosanitary certificates from the country of origin as well as CITES permits. Getting permits for CITES II plants is fairly straightforward, but can take some time and will cost you, as will phytosanitary certificates. CITES I plants are much more difficult to get permits for. It is much easier if they have been tissue cultured. Seeds are exempt from CITES II restrictions, but I think CITES I seeds are still covered. This is why I only sent plants within Europe, as you don't generally need any documentation. And yes, if you have been sending plants abroad without all the required documentation you have been breaking the law. A lot of people do it, but it doesn't make it right.
Oh yes, forgot to say, try this web site Richard
there are some useful links, and I generally find the staff very helpful
