Ningxia Tairui Pharmaceutical

Ningxia Tairui Pharmaceutical is a China-based veterinary pharmaceutical manufacturer focused on the research, production, and global sale of veterinary active pharmaceutical ingredients, formulations, premixes, and feed additives. The company is best known for large-scale antibiotic fermentation and small-molecule anti-infective products including tylosin, tilmicosin, tiamulin fumarate, and erythromycin thiocyanate. It operates as an export-oriented, high-tech enterprise with substantial manufacturing scale in Ningxia and sales into more than 80 countries and regions. Tairui appears to be primarily a commercial manufacturing business rather than a clinical-stage drug developer, with its activity centered on industrial production, regulatory certifications, and global supply of veterinary medicines. The company also has subsidiaries involved in downstream antibiotic and fermentation products.
