Position
We became one of the first generation of Chinese sodium chlorite producers in 1997, began exporting in 2003 — earlier than anyone else in the sector — and have ranked first in the industry on production and export volume since 2007.
The company sits in the one-hour economic circle of the Shandong Peninsula, with Qingdao to the east and Weifang to the west, which is what makes container logistics straightforward from here.

How we work
That is the company’s stated core value, and in practice it means the boring things: we tell you what a certificate does not cover, we do not quote a grade we cannot hold, and we put the hazard information in front of you rather than in an annex.
