The present invention relates to an LPG ISO tank container and, more specifically, to an LPG ISO tank container which is filled with a fixed quantity of LPG gas, is then stacked in a required height in a ship to be transported, prevents movement of filled LPG gas, prevents a temperature increase by radiant heat, allows sturdy and safe transport, rolls a raw material to form a tank by a cylinder method, and installs a corrugated pipe on an outer wall to prevent an external impact. The LPG ISO tank container fills LPG gas in a tank (11) to stack the tank (11) in a ship by a structure (20) to transport the tank (11), and has a manhole (40) with a manhole cover (41) installed on a center of one side of the tank (11). The LPG ISO tank container comprises: splashboards (12) installed on a reinforcing ring (13) installed on an inner circumference thereof at regular intervals in a horizontal direction; and the tank (11) having a connection pipe (16) installed on both sides of an outer circumference thereof. A safety cover (15) is installed on spacing parts (14) installed on an upper side of the outer circumference of the tank (11) at regular intervals. A structure (20) has a bent reinforcing part (24) fixed thereon and coupled to both sides of the connection pipe (16) and a corner casting (37) formed in four directions. A driving box (30) includes a thermometer (31), a pressure gauge (32), a liquid initial value (33), a gas initial valve (34), and a drain valve (35) installed on a lower side of the manhole (40).
