Beijing Keephway Technology Co. has been engaged in R&D and manufacture of Fine Chemicals since its establishment in 2009.
Since the first day we entered the industry, all procedures from raw materials procurement, production and inspection, to the last step of packaging are conducted with the state-of-the-art technologies and highest standards.
We provide fine chemicals to a variety of industries, e.g. Cosmetics, Water Treatment, Pharmaceuticals, Printing & Dyeing, Agriculture, etc.
In 2014, we were awarded the title AAA First-class Enterprise (it means business is a demonstration unit with top-ranking expertise and credibility) and in the same year we were invited to be a member of the CFCRMIIA (The China Fine Chemical Raw Materials & Intermediate Industry Association).
Over the years, we have exported fine chemicals to markets all over the world, amongst are that of U.S., Germany, Republic of Korea, Malaysia, India, etc. and received a lot of positive feedback.
