Hubei Masteam Biotech

Hubei Masteam Biotech is a China-based animal health and pharmaceutical chemistry company focused on the research, manufacture, and sale of veterinary active pharmaceutical ingredients and pharmaceutical intermediates. The company operates GMP manufacturing facilities in Wuxue, Hubei, and markets products through a Wuhan-based commercial entity. Its portfolio appears centered on commercial small-molecule veterinary APIs such as florfenicol, tulathromycin, toltrazuril, fipronil, cefovecin sodium, nicarbazine, mequindox, and oxolinic acid. Masteam also presents itself as a CRO/CMO or CDMO-style supplier for APIs and intermediates, with pilot and GMP workshop capabilities and scale from gram quantities to tons. The business is best characterized as a commercial-stage animal health manufacturer rather than a therapeutic biotech developer with a disclosed human clinical pipeline.
