Cost varies and depends on method of transportation, cubic footage, and weight. Pay for the extra marine or air insurance for peace of mind. Shipping time varies depending on which port your household goods will arrive. If you decide to opt for surface shipping, your goods will probably be taken to a warehouse and stored in an ISO container until there are enough containers ready for shipment. Expect to be separated from your goods for 2-3 months. Opt for door to door service to save you the time and hassle of hiring a van and rounding up some helpful hands to collect your goods from the port of arrival.
