Pharmaceutical & API manufacturing sites in United States

5,394 drug establishments in United States are registered with the US FDA; 513 (10%) list API manufacture among their operations. 3,052 registrant companies are identified, 64 of them with more than one API site here; sites whose registrant is not resolved to a company profile are not counted. 62 published sites are matched to an EU or UK GMP certificate inspected within the last three years.

Counts are physical site addresses in the FDA's current establishment register (US-facing sites only), not headquarters and not production volume. Methodology

Only sites registered with the US FDA appear, so manufacturing that serves only other markets is missing and these figures understate national capacity. A GMP match requires the certificate address to name the site's street and its city or postcode; an unmatched site is not an uncertified site.
