These goods are specific machines. Because the exclusive goods which are specially designed for the device are
considered. Whether that machine, device corresponds to strategic goods to decide as the foreign exchange and foreign
trade control law. You must have it judged.
As for contents of mention of these materials. A service in the foreign exchange and foreign trade control law
(Technology in the design, the manufacture and the use). Be careful of handling because it is likely to correspond.
This product is not designed against radioactive ray.
