Anhui Herrman Impex Co., Ltd. is a privately owned enterpirse with more than Twenty-two years' experiences of foreign trade. Its former shape came from Anhui Herrman Chemicals Co., Ltd., which established in 1994 and devoted itself into the exportation and importation business of Chemicals and Light Industry.
In order to shape an uniform and scientific management system with high efficiency, normalize the operation process and guarantee the advancement of the company in a long term, we made Herrman Chemicals and Herrman Light Industries become one: Anhui Herrman Impex Co., Ltd., which is acknowledged as the headquarters of Herrman group. At the same time, it points out the way we are moving. In 2002, we were certified and approved by ISO9001:2000 Quality System, details of which have been carried out since then and provided strong foundation for normalized management and standard service of the company.
To meet the requirement of company progress, we started Shanghai Herrman Impex Co., Ltd., Nanjing Herrman Chemical Factory, Nelson International Inc. and Anhui Herrman Titanium Dioxide Co., Ltd. in the same year of 2002. All these efforts have been proved to be with important significance in the process of being an industry company.
In a response to rapidy growing machinery business, we set up another specialized company Anhui Herrman Machinery & Technology Co., Ltd. In 2010, responsible for all machinery business.
Looking back and forward, we will keep advancing for the brighter future without hesitation.
