Q: Mongolia Customs?

A: Every tourist will complete a customs declaration form on arrival, which must be retained by them until their departure. This allows the free import and export of articles for personal use during your stay. The contents of checked-in baggage must be declared on arrival if the total value of those contents exceeds US$5000 in value.
Visitors taking antiques and fossils out of the country must have official documentation to do so. Some shops will provide the necessary documents upon purchase.
