We have tried our utmost to steadily provide the high-class dyestuffs to our customers, since we are well aware that leather production requires complicated processes as well as field experience and refined sensibilities to be accumulated with business practice for a long time based on hight-technology. From the very beginning of the structural design for researching & developing any new dyestuff, we never fail to commence studying how many contributions does it make to producing leather of good quality.

We are sufficiently testing the new developed dyestuff every time in our institute laboratory prior to introduction or sales promotion to customers in order to assure of the effects and the existence or non-existence of harmful materials according to international regulation standards and testing methods, and thereby the fresh product becomes known to customers only after proof positive of its effect.

We always do our best to adopt customers' criticism & comments and requirements to be reflected in our R & D scheme for developing new items, as our final goal is not just to sell our products to our customers but to meet their various kinds of needs for making good leather. All our customers have no hesitation in appraising every LECOTAN (our brandname) dyestuff for the excellency of general quality points such as coloring and properties which are essential to hight-class leather dyestuff and for the consistent quality stability without any lot difference as well, with the fact which demonstrates that our constant efforts to be the world-wide top maker of leather dyestuff are being visibly fruitful.
