Article 184th of the Property Law lists the following properties that cannot be mortgaged:
(1) Land ownership; (2) The right to use collectively-owned land such as cultivated land, homestead, private plots and private hills, except those that can be mortgaged according to law; (3) Educational facilities, medical and health facilities and other public welfare facilities of schools, kindergartens, hospitals and other institutions and social organizations; (4) Property whose ownership and use right are unknown or controversial; (5) Property that has been sealed up, detained or supervised according to law; (6) Other properties that may not be mortgaged according to laws and administrative regulations.
It is worth noting that the Property Law also makes special provisions on the mortgage of some special types of mortgagors and their chattels, that is, with the written agreement of the parties, enterprises, individual industrial and commercial households and agricultural producers and operators can mortgage existing and future production equipment, raw materials, semi-finished products and products, and when the debtor fails to perform the due debts or the parties agree to realize the mortgage, the creditors have the right to be paid in priority for the chattels. This means that "future" movable property can also be used as collateral.
