The Avalere report, which looked at APIs—the building blocks of finished pharmaceutical products—comes to a similar conclusion. China is the third largest provider of APIs to the United States, but “no single foreign country dominates the overall supply of API for the U.S. market.”

“This report is another piece of evidence suggesting we’re not wholly dependent on imports from China for finished pharmaceuticals and APIs,” says Clark Packard, a trade policy counsel at the pro-market R Street Institute. “The key is we need more data and evidence before we radically remake this market, but unfortunately policymakers don’t seem interested in a rational approach to this issue.”
