The US Food and Drug Administration (FDA) issued a warning letter to the Cheng Fong Chemical in Taoyuan City, Taiwan.
What prompted this action? It came in the wake of an investigation of the facility in April. The agency noted that the company had not created a “maintenance procedure to prevent contamination or carry-over of a material that would alter the quality of the API.”
Further, the company failed to conduct adequate investigations after receiving customer complaints of the presence of black foreign particles.

The letter was issued September 15.
