After the market closes on the last trading day (the 10 trading day in the delivery month), the Exchange will match the positions in the delivery month by computer according to the principle of rounding off by quantity and minimum matching number. Once the delivery relationship is confirmed, the buyer and the seller shall not adjust or change it without authorization.

On the first trading day after the last trading day (that is, the notification day), the buyer and the seller confirm the delivery notice through the member service system. Members who have not received the delivery notice or have objections to the delivery notice shall notify the Exchange in writing before the notification date 17. If no objection is raised within the specified time, it shall be deemed that before 9: 00 a.m. on the second trading day after the last trading day (i.e. the delivery date) after the approval of the delivery notice, the buyer member will transfer the outstanding amount to the exchange account, and the seller member will hold the standard warehouse receipt certificate. The buyer and the seller shall go to the settlement department of the exchange for specific delivery and settlement procedures within the specified time, and the buyer member shall provide the investor's name and tax registration certificate number to the seller member. On the delivery date, the exchange collects the full amount from the buyer member, transfers 80% of the full amount to the seller member on the same day, and delivers the warehouse receipt of the seller member to the buyer member. When the buyer member confirms receipt of the special VAT invoice transferred by the seller member, the balance shall be settled. The transmission of invoices and the settlement of the balance shall be confirmed by the members' seals and signatures.
