Why you may see different company names
Shandong Jinrunzi Biotechnology Co., Ltd. (also written Shandong Jinrunzi Bio-Tech Co., Ltd.) and Zouping Runzi Chemical Industry Co., Ltd. are two registrations of the same company, so customs data, directories, and audit reports may show either legal name. RunziChem and Rainfert are the company's trade brands.
