Brand, Entities and How We Work

WIS Biotech is the brand under which our gluconate ingredients are marketed worldwide. Two legal entities stand behind that brand. Shandong Zhuozhicheng Biotechnology Co., Ltd. (山东卓智诚生物科技有限公司) is the manufacturing entity, located in Shanghe County, Jinan, Shandong Province, where gluconate salts are produced for food, feed and industrial use. Shandong Definly Chemical Co., Ltd. (山东德丰利化工有限公司) is the group export and trade entity, managing international orders, shipping documents and commercial contracts for buyers outside China.

Our catalog covers sodium, calcium, zinc, ferrous, magnesium, potassium and copper gluconate, glucono delta-lactone (GDL), gluconic acid and maltose. Food grade, feed grade and industrial grade options serve mineral fortification, premix and compound feed, cleaning and textile processing, and concrete admixture formulations. Every shipment can be supported with a product specification, batch certificate of analysis (COA) and safety data sheet (SDS). Halal, Kosher and ISO documentation is issued through Definly Chemicals when the product, site and certified scope apply, so customers can confirm the right paperwork for their market before they order.

Whether you need a first trial bag or a long-term supply program, our team helps match the grade, packaging and documents to your application and destination. Reach out with your specification and target market, and we will reply with availability, lead time and the documents that apply to your order.
