What is an FDA Notice of Detention and Hearing?

It is the notice that both detains an imported shipment and offers the importer a hearing — an opportunity to introduce evidence and argument about whether the goods should be admitted. Despite the word hearing, it is almost always a documentary process: you submit written evidence, such as an independent laboratory report, and legal or factual argument to the FDA compliance officer named on the notice, rather than appearing in a courtroom.

What evidence do I submit for the hearing?

It depends on the charge. For a contaminant, residue, or pathogen charge, the core is usually an independent laboratory report on a representative, custody-documented sample showing the product does not bear the violation. For a labeling or documentation charge, it may be corrected labeling or records or an application to recondition. In some cases the strongest response is a legal or factual argument that the charge does not apply.

How is this different from an import alert detention?

Every detention carries the same hearing opportunity, but the situation differs. In a standard detention, FDA examined or tested this entry and found an apparent violation, and your submission rebuts that finding. Under an import alert (detention without physical examination), the detention rests on prior evidence tied to the product, firm, or country, and the burden is on you to affirmatively present evidence — often private laboratory testing — overcoming the alert's basis rather than disputing a one-time FDA test.

What happens if I don't use the hearing opportunity?

Letting the opportunity lapse without an adequate submission, or failing to overcome the appearance of a violation, moves the entry toward a Notice of Refusal of Admission. A refusal is treated as final and is much harder to undo, so responding within the stated window — or requesting an extension in writing before it lapses — is important.

FDA Notice of Detention and Hearing — What It Means

Q: Is the FDA hearing an actual courtroom hearing?

No. It is an administrative opportunity to be heard, not a trial. FDA considers evidence and argument you submit in writing within the response window before making a final admissibility decision. You generally do not appear before a judge; you assemble a case file and send it to the compliance officer named on the notice.

The notice that detains your shipment also gives you a hearing — an opportunity to present evidence and argument on why the goods should be admitted. Here's what that "hearing" actually is, and how it works.

The Short Version

What Is a Notice of Detention and Hearing?

It's the notice that both detains your shipment and offers you a hearing to contest it. When FDA detains an entry, the Notice of FDA Action gives the importer an opportunity to introduce testimony — evidence and argument — about whether the goods should be admitted. Despite the word "hearing," this is almost always a documentary process: you submit written evidence (such as an independent laboratory report) and legal or factual argument to the compliance officer, rather than appearing in a courtroom. It's your formal chance to overcome the appearance of a violation before FDA decides.

The "Hearing," Explained

A Paper Hearing, Not a Courtroom

The "hearing" in a Notice of Detention and Hearing is an administrative opportunity to be heard — not a trial. In practice, it means FDA will consider evidence and argument you submit in writing within the response window before making a final admissibility decision. You generally won't stand before a judge; you'll build a case file and send it to the FDA compliance officer named on the notice.

What you submit depends entirely on the charge. If the notice cites a contaminant, residue, or pathogen, the core of your submission is usually an independent laboratory report on a representative, custody-documented sample showing the product does not bear the violation. If it cites a labeling or documentation problem, the submission may center on corrected labeling or records, or an application to recondition. In some cases the strongest response is a legal or factual argument that the charge doesn't apply — for example, that FDA has the facts or the applicable requirement wrong.

The opportunity is time-limited. The notice states a period to respond — commonly around 10 business days, though the date on your notice controls — and you can request an extension in writing before it lapses if you need more time to complete testing.

Detention Types

How It Differs From an Import Alert Detention

Every detention comes with this hearing opportunity, but the situation behind it varies. The key distinction is what prompted the detention and where the burden sits:

Standard Detention: FDA examined or tested this entry and found it appears to violate the law. Your hearing submission rebuts that specific finding for this shipment.

Import Alert (DWPE): The detention is based on prior evidence tied to the product, firm, or country — FDA need not test this specific lot. The burden is on you to present evidence overcoming the alert's basis.

The Common Thread: In both, the notice gives you the same opportunity: submit evidence and argument within the window to overcome the appearance of a violation.

The Practical Difference: Under an alert, expect to affirmatively prove compliance (often via private lab testing) rather than simply dispute a one-time FDA test result.

Who Responds: The importer, owner, or consignee — typically working with the customs broker and any technical or legal help — assembles and submits the response.

If You Don't Respond: Letting the hearing opportunity lapse without an adequate submission moves the entry toward a Notice of Refusal of Admission.

Be Realistic

What the Hearing Can and Can't Do

Honest limitations

It's an opportunity, not a guarantee. Submitting evidence entitles you to have it considered — not to a particular result. FDA decides whether your submission overcomes the appearance of a violation.
Quality of evidence matters. A lab report from a sample that wasn't representative or lacked documented custody can be rejected even when the underlying product is fine. How the case is built counts.
The window is short. The whole submission — sampling, testing, argument — has to fit the response period or an approved extension.
It resolves the shipment, not the alert. Prevailing at the hearing can release this entry, but if an import alert applies, future shipments keep facing detention until a separate removal petition succeeds.
Missing it is costly. Once the opportunity lapses and a refusal issues, reversing course is much harder — FDA treats refusals as final absent an agency error.
