No business of designated delivery warehouses may be carried out in futures exchanges. Futures is a standardized trading contract based on some popular products such as cotton, soybean, oil and financial assets such as stocks and bonds. The cancellation of the qualification of the delivery warehouse in this contract means that the business of the designated delivery warehouse cannot be carried out in the futures exchange, in order to make the setting of the delivery warehouse more centralized. Delivery warehouse refers to the commodity storage area specially set up by the futures exchange in the main producing area or main consumption area, which is used for physical delivery of contracts entering the delivery period.
