International movers do use containers when shipping your belongings overseas, but they're not the same type of containers you might find stateside at vendors like U-Haul or PODS. International moving companies use large, commercial containers that come in two sizes: either 20 feet, or 40 feet.  Most self-storage container companies will not allow shipment overseas because of strict import and export laws in each country. As customers pack those themselves, the companies cannot be liable the shipment of prohibited and restricted items.
