The Ministry of Economy, Trade and Industry has issued a statement to the dyeing industry saying that some of the conformations of the color index number disperse orange 30 need to be improved in purity. Disperse orange 30 is a dyestuff playing a part in three primary disperse dye colors. There is a difference in the degree of its purity among dye manufacturers.

Officials expect that if the purity of some disperse orange 30 dyes which are cheaper and less refined reach to the same standard as in Germany, there is a possibility that the price of those items will increase rapidly.
