How to read an FDA Establishment Inspection Report

A Form 483 is what an investigator hands you on the way out the door: a numbered list of observations, terse by design. The Establishment Inspection Report, or EIR, is the document FDA writes for itself afterward — the full narrative behind those bullet points, including the reasoning that ultimately becomes your inspection’s classification. You don’t get a copy automatically. You have to ask for one.

What’s actually in an EIR

An EIR typically opens with background on the firm — history, product lines, prior inspection history — then moves through the scope of what was actually covered during the visit: which areas, which records, which personnel were interviewed. The narrative section is where it earns its name: instead of the 483’s terse observation language, the EIR describes what the investigator saw and why it mattered, often with far more context than the corresponding Form 483 conveys on its own. It closes with the investigator’s own recommended classification and any attachments — photographs, copies of records, other exhibits collected on site.

Why practitioners request them

For your own firm, an EIR fills in the reasoning behind a 483 or an inspection classification you already have — useful when preparing a response, or when trying to understand a pattern across several inspections rather than reacting to one in isolation. For due diligence or competitive benchmarking, a competitor’s or a partner’s EIR shows how FDA is actually treating similar facilities or product types, which is a different and often more grounded signal than the classification result alone.

Most practitioners will read far more Forms 483 than EIRs in a career, and that’s fine — the 483 is what you respond to. But understanding that a fuller narrative exists behind both the 483 and the classification result changes how you read them: as a summary of a longer document, not the whole story. Worth knowing even the first time you see a notice of inspection land on your desk.
