FDA Prior Notice: What It Is and How to File It Before Your Shipment Arrives

Prior Notice is a specific, deadline-driven filing requirement, getting the timing wrong can hold up a shipment even when every other document is in order. Here's exactly how the deadlines work. This is general information, not legal or compliance advice, confirm your specific filing obligations with a licensed customs broker.

What Do the Key Terms Mean?

Prior notice is the advance notification to FDA of a food shipment that is arriving in the United States, and FDA must receive and confirm it before the shipment arrives.

PNSI is FDA's own Prior Notice System Interface, while ABI/ACE is the CBP system through which most customs brokers file prior notice with entry data.

A PN Confirmation Number is the number FDA issues when a prior notice is confirmed, and it must be available to CBP or FDA when the food arrives.

What Is FDA Prior Notice?

Prior Notice is advance notification to the FDA that a food shipment is entering the US, required before the shipment arrives at the first US port. FDA must electronically receive and confirm the notice, a food shipment arriving without confirmed Prior Notice can be held at the port.

How Far in Advance Can Prior Notice Be Filed?

No more than 15 calendar days before the anticipated arrival date if filed through FDA's own Prior Notice System Interface (PNSI), or no more than 30 calendar days before arrival if filed through CBP's Automated Broker Interface (ABI/ACE) (FDA prior notice guidance). Many importers file through a customs broker using the ABI/ACE system, which gives more scheduling flexibility with the longer 30-day window.

What's the Minimum Notice Required Before Arrival?

At least 8 hours before arrival for ocean freight, shorter windows apply to air, rail, and road transport, and ocean freight is the usual mode for bulk seed. This 8-hour minimum is a floor, not a target, filing well before this deadline avoids risk from any last-minute processing delay.

How Is Prior Notice Actually Submitted?

Through either CBP's Automated Broker Interface/Automated Commercial Environment (ABI/ACE) or FDA's own Prior Notice System Interface (PNSI). In practice, a customs broker can file this as part of standard entry processing, so ask your broker whether it will.

What Confirmation Do You Receive After Filing?

FDA issues a PN Confirmation Number once the notice is successfully submitted and confirmed, and that confirmation number must accompany the shipment on arrival at the US port of entry. Losing track of this number, or filing without receiving confirmation, can cause the same hold as not filing at all.

What Happens If Prior Notice Isn't Filed Correctly?

The shipment can be held at the port until the notice is properly filed and confirmed, for a bulk food shipment, this can mean demurrage costs accumulating while the issue is resolved, on top of the delay itself. This is exactly the kind of documentation timing risk covered generally in our complete import guide.

Who Is Typically Responsible for Filing Prior Notice?

FDA's guidance says any person with knowledge of the required information can submit prior notice, so it may be the importer or its customs broker. Confirm with your broker that Prior Notice filing is included in their standard process for your shipment, rather than assuming it happens automatically.

Does Prior Notice Apply Separately From FSVP?

Yes, Prior Notice and FSVP are two separate, independent requirements that both apply to most food shipments entering the US. FSVP is about verifying your foreign supplier's food safety practices on an ongoing basis; Prior Notice is a per-shipment filing confirming a specific shipment's arrival details. Meeting one requirement doesn't satisfy the other, both need to be handled for a compliant import.

Can Prior Notice Be Filed Too Early?

Yes, filing outside the allowed window (more than 15 days ahead via FDA's PNSI, or more than 30 days ahead via CBP's ABI/ACE) means the submission won't be accepted, and it will need to be refiled once you're within the correct window. This is part of why coordinating the exact filing timing with your customs broker, rather than filing speculatively far in advance, matters.

What Information Does a Prior Notice Filing Actually Require?

Beyond the importer's identification details, a Prior Notice filing includes information about the specific shipment, product description, quantity, manufacturer, country of origin, anticipated port of arrival, and carrier information. Your customs broker will typically pull most of this directly from your commercial invoice and other shipping documents, which is one more reason having accurate, complete documentation ready before the shipment departs matters.

Does Prior Notice Need to Be Refiled If a Shipment's Schedule Changes?

Yes, if the vessel's estimated arrival shifts enough to fall outside the window your original Prior Notice was filed under, or if key shipment details change (carrier, port of arrival, quantity), FDA's guidance says to cancel and resubmit when details change rather than assuming the original filing still covers the updated schedule. Ocean freight schedules shift often enough, weather delays, port congestion, carrier rerouting, that this is a realistic scenario worth planning for rather than a rare edge case.

Keeping your customs broker informed of any schedule change as soon as you're aware of it, rather than after the fact, gives them the best chance of refiling within the correct window without it becoming a last-minute scramble right before arrival.

What Are the Deadlines for Each Transport Mode?

The minimum lead time depends on how the food arrives, and prior notice must be submitted and confirmed by FDA before that deadline (FDA prior notice guidance, citing 21 CFR 1.279). Bulk sunflower seed from China arrives by water.

How Far in Advance Is the Earliest Filing?

Through CBP's ABI/ACE the earliest filing is 30 calendar days before the anticipated arrival, and through FDA's PNSI it is 15 calendar days (FDA prior notice guidance). As an illustration, for a vessel due to arrive on 20 February the earliest PNSI filing would be 5 February and the earliest ABI/ACE filing 21 January (calculated).

Does a Confirmation Number Mean the Shipment Is Cleared?

No. FDA's guidance states that a PN Confirmation Number is evidence only that a prior notice has been received for FDA review, and FDA may still decide that a food should be examined or sampled at the border, or refuse it if the notice is inaccurate or untimely (FDA prior notice guidance). Confirmation is a necessary step, not a release.

What Does Refusal of Admission Mean in Practice?

Food that is imported or offered for import without adequate prior notice is subject to refusal of admission under the prior notice rule, and if refused it may not be delivered to the importer, owner or ultimate consignee (FDA prior notice guidance, citing 21 CFR 1.283). For a bulk shipment, that means the cost of holding the container while the notice is corrected, which is why the 8-hour minimum should be treated as a legal floor and not a target.

What Are the Limits of This Guide?

The timing rules are those in FDA's guidance on the date we checked. Systems and rules change, and this guide does not replace your customs broker, who files the notice and knows the current process.
