What is the FDA detention timeline?

It runs in stages: FDA detains the entry and issues a Notice of FDA Action with a respond-by date; you have a response window (commonly around 10 business days) to submit evidence, apply to recondition, or request an extension; FDA reviews and either releases the shipment or issues a Notice of Refusal of Admission; and if refused, the goods must be exported or destroyed within 90 days under CBP and FDA supervision. The dates on your specific notice always control.

How long do I have before an FDA detention becomes a refusal?

Until the respond-by date on your Notice of FDA Action passes without an adequate response, or until FDA determines your evidence does not overcome the appearance of a violation. The response window is commonly around 10 business days, though some notices allow more calendar time. You can request an extension in writing before the date; whether it is granted is at FDA's discretion.

What happens after an FDA refusal?

A refusal is treated as final and means the goods cannot enter U.S. commerce. They must be exported or destroyed within 90 days of the refusal notice, under CBP and FDA supervision. FDA has no authority to extend the 90-day period, and missing it can lead CBP to assess liquidated damages against the import bond, potentially up to three times the value of the merchandise.

Does the respond-by date mean testing must be finished by then?

No. The respond-by date is the deadline to respond, not to complete laboratory testing. The common approach is to notify the FDA compliance officer named on the notice, before the date, that testing is underway and to request an extension in writing where appropriate. Testing is then completed within any extension granted.

Is removal from an import alert part of the same timeline?

No. Releasing a detained shipment and removing a firm from an import alert are separate tracks. Even after a shipment is released, future shipments can keep being detained under the alert until a separate removal petition is filed and approved. Alert removal has no fixed clock and depends on demonstrating that the underlying conditions were corrected.

The FDA Detention-to-Refusal Timeline

FDA detentions run on a clock. Here's the sequence from the moment your shipment is detained through response, release, or refusal — and the deadlines that decide which way it goes.

The Short Version

Detention Is a Clock, Not a Verdict

A detention starts a response window; a refusal ends it. When FDA detains your shipment it issues a Notice of FDA Action with a respond-by date. You use that window to overcome the appearance of a violation — with evidence, reconditioning, or a request for more time. Respond well and the shipment can be released. Let the window close without an adequate response and FDA can refuse the shipment, which triggers a separate 90-day clock to export or destroy the goods. The whole game is staying ahead of these deadlines.

The Sequence

The Clock, Stage by Stage

Timeframes vary by case and the dates on your own notice always control, but the order of events is consistent:

Detention & Notice of FDA Action

FDA determines the entry appears to violate the law and issues the notice to the importer, owner, consignee, and broker. The respond-by date is set here. The clock starts.
The Response Window

Commonly around 10 business days (sometimes more calendar time for weekends, holidays, and mailing — follow your notice). This is the deadline to respond, not necessarily to finish testing.
Your Response

Within the window you submit evidence overcoming the charge, apply to recondition or relabel (Form FDA 766), or notify the compliance officer that testing is underway and request an extension in writing.
FDA Review & Decision

FDA weighs your evidence or reconditioning result. If it overcomes the appearance of a violation, the entry is released. If not — or if nothing adequate arrives in time — the case moves toward refusal.
Release or Refusal

A release lets the goods enter U.S. commerce. A Notice of Refusal of Admission means they cannot — and FDA treats a refusal as final, reconsidered only where the agency made an error.
After a Refusal: the 90-Day Clock

Refused goods must be exported or destroyed within 90 days, under CBP and FDA supervision. FDA cannot extend this period. Missing it can lead CBP to assess liquidated damages against the import bond — potentially up to three times the value of the goods.

The Deadlines That Matter

Key Clocks at a Glance

Respond-By Date: Commonly ~10 business days from the notice — the deadline to respond to FDA. The date on your notice controls.

Extension: May be requested in writing before the respond-by date; granting is at FDA's discretion. Useful when testing needs more time.

Testing Deadline: There is no separate "finish testing by" date — you must respond by the date, then complete testing under any extension.

Export or Destroy: Within 90 days of a refusal, under CBP/FDA supervision. FDA has no authority to extend this window.

Liquidated Damages: If the 90-day deadline is missed, CBP may claim up to three times the value of the merchandise against the bond.

Alert Removal: A separate track entirely — no fixed clock. Future shipments keep being detained until a removal petition succeeds.

Be Realistic

Why the Early Days Decide the Outcome

What the clock rewards and punishes

The response window is short. Representative sampling, lab analysis, and a documented submission all have to fit inside it — which is why sampling should start in the first days, not the last.
Refusal flips the odds. Overcoming a detention is a normal process; overturning a refusal requires showing FDA made an error, and the agency rarely accepts new testing or reconditioning afterward.
The 90-day clock is firm. FDA can't extend it, and missing it puts your bond at risk through liquidated damages.
Release doesn't stop the next detention. If an import alert is involved, each future shipment restarts this same clock until the firm is removed from the alert.
No timeline guarantees an outcome. Meeting every deadline gives you the best shot; it doesn't obligate FDA to release, and whether evidence overcomes a charge is FDA's decision.
