openFDA Drug Enforcement
Report-date coverage
June 20, 2012–July 08, 2026
Known gap: openFDA describes 2004-present coverage, but the current export has no report-date records in this interval.
Enforcement coverage uses report dates; product initiation dates can precede those bounds. Device-enrichment coverage uses FDA event_date_initiated.
Product dates, classifications, firms, and source wording remain attached to their individual rows.
Opening this dossier never hides products that did not match a prior timeline filter.
