You sure do. Any transfer of shipment, also of private items, need to pass through customs. A customs broker will assist you in shipping the apartment contents and your private items, from the point of packing, sea freight or air freight, insuring your equipment and clearing it in customs. Likewise, there are certain benefits with regards to capacity limits for new immigrants and returning citizens that you may enjoy, and receive advisory assistance for this purpose from a licensed party.
I am sending apartment contents abroad for the sake of relocation; do I need to hire a customs broker?
