"Prohibited articles
Among articles which are prohibited from importation are the following types of products:
# Finely powdered snuff.
# Moist snuff to be used orally, also available in bags.
If a traveler suspects that the importation of any item, which he is bringing to Iceland, might be restricted or prohibited, he should declare and produce it at customs at his own initiative."
Troligen är det en anpassning till EU:s snusförbud.
