Definition
FDA Prior Notice is the advance electronic notice that FDA must receive before food for humans or animals is imported or offered for import into the United States. It applies broadly to imported food shipments and gives FDA time to review shipment information before arrival at the U.S. border. FDA filing guidance
For buyers, the practical point is simple: Prior Notice is not a general customs formality. It is a shipment-specific FDA filing that sits alongside food facility registration and import entry work, and it is one of the first things that can stop a shipment when the data is late, inaccurate, or incomplete. FDA Prior Notice guidance
Why it matters
FDA uses Prior Notice to target inspections and examinations of imported food at U.S. ports of entry and to assess whether a shipment may present a public-health risk. That is why the filing is tied to arrival timing, product identity, and manufacturer information rather than treated as a back-office afterthought. FDA importing human foods
If Prior Notice is inadequate, FDA can refuse the food under the Prior Notice rule, and refused food is generally held at the port of entry unless FDA or CBP directs otherwise. More broadly, FDA states that imported food shipments may be detained when they do not comply with U.S. requirements. FDA compliance policy guide
When Prior Notice is required
Prior Notice is required for food for humans and animals that is imported or offered for import into the United States, unless a specific exemption applies. FDA guidance makes clear that the rule generally still applies even when the food is for further processing, not intended for commercial distribution, or not intended for consumption in the United States.

A common misconception is that facility-registration exemptions remove the Prior Notice obligation. They do not. FDA explains that even when a farm is exempt from food facility registration, the food grown, harvested, or collected on that farm is generally still subject to Prior Notice when imported.

Who files it
Any individual with knowledge of the required information can submit Prior Notice. FDA specifically includes manufacturers, exporters, brokers, importers, and U.S. agents among the parties who can file. FDA Prior Notice guidance
In practice, many foreign food manufacturers rely on a customs broker, importer, or compliance partner to transmit the filing because the operational risk is in the details: product coding, manufacturer identity, arrival timing, and corrections when shipment data changes. FDA Entry Point states that it files Prior Notice as part of its food compliance service for foreign manufacturers entering the U.S. market. FDA Entry Point Prior Notice service
Timing windows before arrival
The filing deadline depends on the mode of transportation, and FDA must confirm the submission before the shipment arrives. That timing logic is what catches many teams: the clock is tied to the anticipated port arrival, not to when the commercial paperwork was prepared internally. FDA Q&A guidance PDF
| Mode of arrival | Minimum lead time before arrival |
|---|---|
| Land by road | 2 hours |
| Land by rail | 4 hours |
| Air | 4 hours |
| Water | 8 hours |
| International mail | Before the food is sent |
FDA also sets outer windows for how early a filing can be made: no more than 30 calendar days before arrival when submitted through CBP’s ABI/ACE/ITDS interface, and no more than 15 calendar days before arrival when submitted through FDA’s Prior Notice System Interface, or PNSI.

How multi-product shipments work
The part buyers usually underestimate is that Prior Notice is article-based, not shipment-based. FDA states that each article of food requires Prior Notice, and you cannot file one notice to cover all repetitive shipments. FDA Q&A guidance PDF
For mixed loads, that means one truck or container can carry multiple Prior Notice submissions. Separate notices are required when the foods differ by complete FDA product code, package size, or manufacturer or grower. Different brand names alone do not automatically create separate Prior Notice filings if the underlying article of food is otherwise the same for Prior Notice purposes. FDA Q&A guidance PDF
A pattern worth naming: the more consolidated the shipment, the less forgiving the process becomes. A single late or inaccurate notice can disrupt a load that looked operationally simple on the warehouse side but is actually several FDA-reportable food articles on the import side.
How Prior Notice interacts with food facility registration and the U.S. Agent
Prior Notice does not replace food facility registration. FDA’s import guidance treats them as separate requirements: imported food facilities that manufacture, process, pack, or hold food for U.S. consumption generally must be registered, and incoming shipments also require Prior Notice. FDA importing food products
That connection becomes concrete in the filing itself. FDA guidance says that when the food is no longer in its natural state, the Prior Notice submission must include the manufacturer’s name and either the facility registration number plus city and country, or the full manufacturer address and the reason the registration number is not provided. FDA Q&A guidance PDF
The U.S. Agent matters differently. For foreign food facilities, the U.S. Agent is part of the facility-registration framework in FDA’s registration system, but the U.S. Agent is not the only party who can file Prior Notice. In real workflows, the U.S. Agent may coordinate with the broker or importer, but the filing responsibility is operational rather than title-based. FDA food facility registration user guide
What usually goes wrong
FDA defines inadequate Prior Notice as no notice, inaccurate notice, or notice submitted outside the required timeframes. Those are the three failure modes that matter most in practice. FDA Q&A guidance PDF
- Arrival time was estimated too aggressively, so the shipment reaches the port before FDA’s minimum review window has run.
- A mixed shipment was treated as one filing when it actually contained multiple reportable food articles.
- The manufacturer or registration data in the notice does not match the actual food article.
- A shipment changed after filing, but the notice was not corrected or resubmitted in time.
For stretched regulatory teams, this is why Prior Notice is often less about legal interpretation than about execution discipline. The rule itself is stable; the operational errors happen when shipment data changes late or when multiple parties assume someone else handled the filing.
Usage examples
Example 1: One truck, many SKUs
A Canadian exporter sends one truckload containing several packaged snack products in different package sizes. Even though it is one physical shipment, separate Prior Notice submissions may be needed for each distinct article of food based on product code, package size, or manufacturer. FDA Q&A guidance PDF
Example 2: Air shipment with a short lead time
A specialty ingredient shipment is booked on a flight landing in the U.S. the same afternoon. Prior Notice must be confirmed by FDA at least 4 hours before arrival by air, so a filing made too close to departure can still be too late operationally. FDA Q&A guidance PDF
Example 3: Registered facility, but no usable shipment filing
A foreign food facility has valid registration and a designated U.S. Agent, but the broker submits inaccurate manufacturer information in the Prior Notice. Registration alone does not cure the error; FDA can still treat the Prior Notice as inadequate and hold or refuse the shipment. FDA compliance policy guide
