About Us
Three Production Bases. One Quality System. Since 2008.
Shandong Haineng Bioengineering Co., Ltd. was established in 2008 in Rizhao, Shandong. We combine research, production and technical promotion of 25-OH-D3, liquid vitamin raw materials, liquid feed additives and vitamin premixes.
Over 18 years the company has built three production bases in Rizhao and developed product lines covering animal nutrition and related application fields. Our work is organised around documented quality systems and applied nutrition research shared with customers.
We were the first company in China to obtain the feed-additive production licence for 25-OH-D3. The technology is protected by a Chinese national invention patent, and we took part in drafting the national industry standard NY/T 4688-2025 for 25-hydroxycholecalciferol.
