This is a use case where Japan already has a significant lead. They are quite far along the testing and demonstration phase of TradeWaltz, which will use blockchain to replace paper documents and automate import/export procedures and customs for containerised freight between Japan and friendly nations. It should significantly reduce costs and increase speed and authentication of information. The only downside is that although it's using blockchain technology, it is not decentralised.
