Expansion of Production Capacity for Inorganic Salts

Nantong, China


In April 2020, we opened our new excipient and API manufacturing plant in Nantong, China. With this new facility, we have added significant capacity to our global manufacturing network and enhanced supply reliability. In addition to providing multi-compendial Emprove® Excipients and APIs, the expansion in China further strengthens our ability to keep pace with evolving regulatory requirements such as the Chinese co-review registration for excipients.
