In this study, a proposal for revision of HSK Code was established on legally designated minerals and national stockpile minerals. It is difficult to exactly identify trade balances of minerals, such as lithium ore, rare earth ore, serpentine, kidney stone in legally designated minerals and ingot of indium, ferro-tungsten, ingot of antimony, granule of selenium, gallium, lanthanum oxide, cerium carbonate in national stockpile minerals because HSK Codes of them were not allocated separately. Furthermore, specific use, standard, component, type of products cannot be exactly identified in current HSK Code system. Therefore, it is makes rule to separately manage minerals which were managed by government such as legally designated minerals and national stockpile minerals. However, a proposal for revision of HSK Code system was established to comply with international standard(HS Code) and the items over a certain size(amounts : over 50 mil.$, volumes : over 5000 ton) were selected as revised subjects. Moreover hierarchies between HSK Codes were considered.
