Im from Norway, and customs seems to have gotten way stricter lately. Anything that they find fishy, they'll stop. Even if it isn't illegal or if it requires a prescription, they'll still stop it, because they lack knowledge so they wont allow it. I think it is some new rule where they can claim medical prespcriptions for anything, escpecially is it is from outside EU. They are allowed to decide what they want to let it, and what not to. Sometimes I think they dont want to bother with checking the package, so they just keep it to be safe. Redicilous.
