Detention doesn't need a warning letter

Every source this column has described so far arrives shaped like an event: a letter posted on a Tuesday, a recall classified this week, a rule with a comment deadline attached. FDA Radar’s four feeds are built around that shape — something dated, something new, worth a reviewer’s attention the week it posts. An import alert is not that shape. It is a standing list, and a firm can sit on one for years with nothing that looks like an event happening at all.

Detention without physical examination, in one sentence

The Federal Food, Drug, and Cosmetic Act gives FDA the authority, at 21 U.S.C. § 381(a), to refuse admission to any imported article that appears to violate the Act — the appearance standard, not a finding proven fresh at every border crossing. Import alerts are how FDA operationalizes that authority in public: a named list of firms and products FDA will detain without physically examining the shipment, because a documented pattern already exists. Import Alert 89-04, “Detention Without Physical Examination of Devices from Firms that Have not met Device Quality System Requirements,” is the device-specific version — appropriate, in the alert’s own language, once an FDA inspection has revealed that a firm is not operating in conformity with device quality system requirements, or once FDA receives inspection information from a foreign government under a formal agreement showing the same thing.

The list doesn’t wait for a warning letter

Placement on 89-04 is keyed to what an inspection found, not to whether that finding was ever escalated into a published warning letter. A firm can land on the list directly from an inspection’s findings, and it stays there, in the alert’s own words, “until such time as FDA is satisfied that the appearance of a violation has been removed, either by re-inspection or submission of appropriate documentation.” No warning letter has to exist at any point in that sequence, and nothing about the listing depends on one being published. A device team that reads every warning letter FDA posts and every recall FDA classifies can be current on both feeds and still miss a listing that is, right now, already deciding whether a supplier’s shipments clear a U.S. port.

A warning letter is a document FDA chose to publish. A listing on 89-04 is a condition FDA chose to impose. The second does not wait on the first, and can outlast it.

No API, because nothing here was built to be one

Every other source in this column’s corpus — Federal Register notices, warning letters, openFDA’s enforcement and 510(k) endpoints — exists as structured, queryable data. Import alerts do not. Each one, including 89-04, lives at accessdata.fda.gov as its own static page, organized into a Red List of firms and products currently subject to detention and, where FDA has granted one, a Green List of firms cleared out from under it. There is no JSON endpoint behind either list, and none of the four sources FDA Radar reads touches this one at all. The handful of tools that do track this space work by scraping the page, not by calling an API FDA publishes, because no such API exists to call.

The practice

A portfolio that depends on a manufacturing partner outside the United States has a check here that no warning-letter feed or recall feed reproduces: read the device-relevant import alerts — 89-04, and the rest of the 89-series — by firm name, directly, on a cadence of a reader’s own choosing. FDA Radar doesn’t monitor import alerts today; per what we monitor and how often, its four feeds are Federal Register, warning letters, and two openFDA device endpoints, and this sits outside all of them, same as it sits outside every other automated feed built on top of FDA’s structured data. Whether a listing changes anything for a specific supplier relationship is a judgment for whoever owns that relationship, on the facts of that relationship — this is a description of how one compliance action works, regulatory intelligence and method, never a determination about any firm named on these lists today.
