The solution to the expiration of the steel mill's cargo right is to transfer the cargo right back to the company. The manager of the purchasing department is responsible for implementing the procurement control management procedures and handing over the settled and expired goods rights to the company. Steel mills and big agents control the cargo rights and cooperate with futures companies to do more. As long as the ownership of the goods is not dispersed, steel mills and futures companies can stock up the goods, and it is no problem to ensure the profit of 100%.
