FDA Notice of Action — What It Means & How to Respond
If FDA detained your shipment, you received a Notice of FDA Action with a respond-by date and a strict clock attached. Here's what the notice is, what its key fields mean, and what your response options are — before that deadline passes.
The Short Version
What Is an FDA Notice of Action?
A Notice of FDA Action is the document FDA issues when it takes an action on your imported entry — most importantly, detaining it. When a shipment appears to violate the law, FDA mails a Notice of FDA Action (Detention) to the importer, owner, consignee, and customs broker. It identifies the entry, the specific charge, the FDA compliance officer to contact, and — critically — a respond-by date. That date starts a strict clock: respond in time with the right evidence, and the shipment can be released; miss it, and FDA can refuse the shipment entirely.
Act on the date on your notice. The respond-by window is commonly around 10 business days, though notices may allow more calendar time for weekends, holidays, and mailing. Do not rely on a general rule — the date printed on your specific notice controls. If yours is close, treat it as urgent.
Reading the Notice
The Fields That Matter Most
- The Charge
- The specific violation FDA is citing (for example, adulteration for a pathogen, pesticide, or color additive, or a labeling/misbranding issue). This defines what evidence can overcome it.
- Import Alert Number
- If the detention is under an import alert (DWPE), the alert number appears here. It tells you the detention is based on prior evidence, not a test of this specific lot.
- Respond-By Date
- The deadline to respond to FDA. This is the single most time-critical field on the notice.
- Compliance Officer
- The named FDA contact for this entry — the person you notify, ask questions of, and submit evidence to.
- Entry & Product Details
- Entry number, product description, and the portion of the shipment affected — sometimes only part of a shipment is detained.
- Parties Notified
- Importer, owner, consignee, and customs broker. Note the "importer of record" (bond holder) may differ from the U.S. consignee FDA calls the "importer."
The respond-by date is the deadline to respond — not to finish testing. This trips up many importers. You generally don't have to complete laboratory analysis by that date; you have to respond by it. The common approach is to notify the compliance officer before the deadline that testing is underway and, where appropriate, request an extension in writing.
Your Options
How You Can Respond to a Detention
A detention is not a refusal — it's an opportunity to overcome the appearance of a violation. There are generally a few paths, and the right one depends on the charge:
-
Submit Evidence
Provide evidence that the product does not have the cited violation — commonly an independent laboratory report on a representative, custody-documented sample, or documentation and legal argument that the charge doesn't apply.
-
Recondition or Relabel
For some violations (often labeling), you can apply to bring the product into compliance using Form FDA 766. FDA must approve the plan and later verify it. Some charges — like a non-permitted substance — cannot be reconditioned away.
-
Request More Time or Accept Refusal
You can request an extension in writing before the deadline if you need it, or — if the goods can't be brought into compliance — accept refusal and arrange export or destruction. Doing nothing lets the clock run to refusal by default.
Where the answer is laboratory evidence, that's the piece we coordinate — representative sampling, chain of custody, and independent (LAAF-accredited where required) testing organized into a case file. See how the process works.
The Stakes
What Happens If You Miss the Deadline
If FDA doesn't receive an adequate response by the respond-by date — or if the evidence submitted doesn't overcome the appearance of the violation — the compliance officer can issue a Notice of Refusal of Admission. A refusal is much harder to undo than a detention: FDA treats a refusal as final and generally reconsiders it only where the agency made an error of law, science, fact, or procedure.
Once refused, the shipment cannot enter U.S. commerce. It must be exported or destroyed within 90 days of the refusal notice, under CBP and FDA supervision. FDA has no authority to extend that 90-day period.
Missing the export-or-destroy deadline has a further cost: CBP can assess liquidated damages against the import bond — potentially up to three times the value of the merchandise. This is why acting while the entry is still in the detention stage matters so much: the detention window is where the affordable options live.
A few honest realities
- "I never got the notice" rarely works. FDA generally expects the parties on the entry to track the respond-by date; missed-notice and hardship arguments are seldom accepted.
- Speed beats everything. Options narrow as the clock runs, and they narrow sharply once a refusal issues. The earliest action is almost always the cheapest.
- Release of a shipment is not removal from an alert. If your detention is under an import alert, clearing this entry doesn't stop future shipments from being detained — that's a separate removal petition.
- No one can promise an outcome. Whether evidence overcomes the charge is FDA's call. Good sampling and documentation remove avoidable weaknesses; they can't change what's in the product or guarantee acceptance.
