Key Insights

  • The FDA continues to follow complaints across all manufacturing entities and is clearly taking those complaints seriously.
  • Drugs including API and supplement manufacturers received more than half of all warning letters.
  • Supplement manufacturers have received a slew of letters for unvalidated scientific claims about the healing properties of their “natural” product ingredients.
  • The vaping/e-cigarette industry is now feeling the pain of being subject to new rules added August 8, 2016 to the Tobacco Control Act.
  • Insanitary seafood preparation and packing still remain a major HACCP violation.


In calendar year 2016, the overall number of quality management system surveillance inspections by the FDA was slightly higher. Certain citation patterns are certainly emerging in 2017.  Will the 80/20 warning letter breakdown between domestic and international manufacturers continue for the rest of 2017?
