Global API Manufacturing Landscape

Major API Producing Countries

1. India
   India remains a dominant actor in the API supply chain owing to its large-scale API manufacturing capabilities, cost advantages, and extensive experience. Several top-tier Indian API manufacturers, such as Divi's Laboratories, Sun Pharmaceutical Industries, and Dr. Reddy’s Laboratories, produce APIs for antiviral drugs, including compounds similar to or identical with the API in StarLix.
   Indian API producers are often certified by global regulatory agencies like the US Food and Drug Administration (FDA) and European Medicines Agency (EMA), enhancing export confidence[1].

2. China
   China’s API industry supplies a significant proportion of global APIs, especially for complex molecules like antivirals. Chinese manufacturers benefit from extensive infrastructure, economies of scale, and longstanding industry experience. Companies such as Huahai Pharmaceutical and Zhejiang Hisun Pharmaceutical have capacities aligned with international standards. However, variability in regulatory oversight has historically posed challenges[2].

3. Europe and the United States
   While smaller in scale, European and U.S.-based API manufacturers—such as Bayer, Novartis, and Catalent—serve niche markets or produce APIs under stringent regulatory frameworks. These manufacturers often focus on high-quality, complex APIs for proprietary or specialty formulations with emphasis on regulatory compliance and supply security[3].
