International moving company can in other words be described as freight forwarders who transport goods from one location to another. This can be done by transporting through air, sea or via road. An international moving company  transports goods between services. These can be providing high end services i.e. managing your entire supply chain providing goods directly from your production center to your distributors or directly to your consumers. Or they could be third party logistical provider (3PL) who basically is point of contact between a shipper or an airline and a shipper. They take the rates from varies shippers at a lower rate than if a shipper contacts them directly which is possible if a 3PL guarantees that he will give the shipping company a certain amount of bulk business every year.
