Shipped item, now buyer is complaining about import duties (US-Norway) What do I do?

[SpartanD63]

Hello! I shipped an item worth $400 to a buyer in Norway. I didn't mark it as "gift" or something like that, because it wasn't.

Now, the item's tracking has been in customs for several days now. Meanwhile the messages from this buyer seem a bit odd, especially the costs cited, though I'm not too familiar with Norwegian customs. Stuff like saying that he'd have to pay $400 to get it through customs if I marked it as an item I sold him? And if the value was over $100. That seems... odd to me.

Any help or suggestions of what to do would be appreciated.

Sorry thought as it was a ''tongue in cheek'' comment with a winking emoji you would take the comment in the way it was meant.......... with a sense of humour.

But at the end of the day all countries have buyers that don't like paying their customs fees so I would never single out any country on any forum where lots of different buyers from different countries post.
