what about international shipping?
I know it depends on the country of the buyer, but let's say USA
As a traveler, you're allowed to import 200 cigarettes (1 carton) into the country without having to pay taxes
Traveling and trading is two different things.
The import tax will always depend on the importing country, I do not know the rules for the countries outside EU.
As a seller then is your only obligation: not to sell anything that is illigal to export to the the given country ... and you must write a custom declaration... the burden on import tax is on the buyer.
Said in a different way, all you need to do as a seller, is to check that it is not illigal to export cigarettes to the given country and write a correct declaration.
In EU, then should you not do anything at all, just ship (afaik)
Also another thing:
You need to make clear, who should be responsible if a parcel is lost?
Is it you? is it the buyer? do you split?
This is a considerable risk as a seller, and since you are none-profit, then will you over time have negative profit, if you have to soach up the loss for missing parcels.
