Provenance

A company is listed because at least one of its establishments in Japan is registered with the FDA for API manufacture. The country is where that plant is, not where the company is headquartered. A registration is not an FDA approval, an inspection result or a quality rating. Country pages exist where 5 or more companies qualify. Methodology.
