FDA Prior Notice for Food Imports: Complete Compliance Guide (2026)

What Is FDA Prior Notice?

FDA Prior Notice is a mandatory pre-arrival electronic notification submitted to the US Food and Drug Administration before any food or animal feed is imported or offered for import into the United States. It is not a customs entry document, a health certificate, or an inspection request. It is a stand-alone, per-shipment compliance requirement that exists entirely within the FDA's regulatory framework.

The purpose of Prior Notice is to give the FDA advance information about incoming food shipments so that the agency can screen and evaluate them before they arrive at the US port of entry. This advance notice allows the FDA to allocate inspection resources, identify potential public health risks, and coordinate with US Customs and Border Protection (CBP) to hold or redirect shipments that warrant physical examination before release into US commerce.

Prior Notice applies to human food, animal food, and animal feed. It applies regardless of whether the food requires a CBP consumption entry, whether it enters a bonded warehouse, foreign trade zone, or moves under bond to an inland port. The only foods that do not require Prior Notice are those specifically enumerated as exempt under 21 CFR 1.277 (covered in Section 7 of this guide).

Legal Basis and Regulatory Authority

FDA Prior Notice was established by the Public Health Security and Bioterrorism Preparedness and Response Act of 2002 (the Bioterrorism Act), which added Section 801(m) to the Federal Food, Drug, and Cosmetic Act (FD&C Act). FDA implemented the Prior Notice requirement through a final rule codified at 21 CFR Part 1, Subpart I (Sections 1.276 through 1.285).

The regulation has been amended several times since its 2003 implementation. The most significant recent amendment was published in the Federal Register on September 25, 2025 (90 FR 46055), which added requirements for the submission of mail tracking numbers for food articles arriving by international mail, effective October 1, 2026, and clarified timeframes for post-refusal and post-hold Prior Notice resubmissions.

Who Must File FDA Prior Notice?

The Prior Notice requirement applies to any person who imports or offers for import a food article into the United States. In practice, this means the importer of record, the importer's authorized agent, the owner or consignee of the food, or any other person with knowledge of the required information listed in the Prior Notice fields.

The submitter does not need to be the importer. Prior Notice can be submitted by:

• The importer of record directly, using their own FDA PNSI account
• A licensed customs broker acting on behalf of the importer through CBP's ACE/ABI system
• A licensed freight forwarder with ABI authorization, filing as part of the entry submission
• The foreign exporter or supplier, submitting through PNSI before the shipment departs
• Any other authorized person with the required shipment information

In most commercial import operations, Prior Notice is submitted by the importer's licensed customs broker as part of the standard CBP entry process through ACE/ABI. This approach is the most efficient for commercial shippers because it integrates Prior Notice into the same pre-arrival workflow as the CBP entry, minimizing the risk of deadline mismatches between the two filings.

Who Does Not Need to File?

A person does not need to file their own Prior Notice if someone else with authorization has already filed on their behalf and the FDA has confirmed receipt. The FDA system issues a unique Prior Notice Confirmation Number (PN Confirmation Number) upon acceptance of each submission. This number must accompany the food shipment upon arrival and be presented to CBP or FDA at the port of entry.

Submission Deadlines by Transport Mode

The most operationally critical aspect of FDA Prior Notice for logistics teams is the transport-mode-specific deadline structure. These deadlines are not suggested timelines. They are regulatory minimums, and missing them is a direct compliance violation that triggers shipment refusal.

For ocean freight importers, the 8-hour minimum advance notice for water arrivals is the most relevant deadline. This means Prior Notice must be submitted and confirmed by FDA at least 8 hours before the vessel arrives at the US port of entry. In practice, responsible importers and their freight forwarders file Prior Notice well in advance of the deadline, typically at the time of the original customs entry filing, which occurs days before the vessel arrives.

For food arriving at US ports by ocean freight, many customs brokers and freight forwarders submit Prior Notice as part of the pre-arrival entry process, which takes place 5 or more days before the vessel arrives. This is the most reliable approach and eliminates the risk of last-minute confirmation delays from the FDA system.

Required Information Fields for FDA Prior Notice

The Prior Notice regulation at 21 CFR 1.281 specifies the exact information fields that must be included in every submission. A submission that omits required fields or contains inaccurate information is treated as deficient and may result in a hold or refusal pending correction.

The following is the complete list of required information fields under 21 CFR 1.281(a)(1) through (18):

• Submitter information: Name, business address, phone number, and email address of the individual submitting the Prior Notice, and the name and address of the submitting firm.
• Food article identity: FDA product code, common or usual name or market name, estimated quantity and unit of measure, and lot or code numbers if available.
• Manufacturer information: Name, address, and FDA food facility registration number of the last manufacturer or processor of the food (if registered).
• Shipper information: Name, address, and phone number of the shipper, and the country from which the food is shipped.
• Country of origin: The country where the food was grown, manufactured, or processed.
• Importer information: Name, address, and phone number of the US importer of record, and the US importer's FDA food facility registration number if the importer is a food facility.
• Ultimate consignee: Name and address of the person or business that will receive the food for sale or distribution in the United States.
• Carrier and transport details: Name of the carrier (ship name, airline, trucking company), mode of transport, bill of lading or airway bill number, and container number.
• Anticipated arrival information: Anticipated date, time, and US port of entry arrival for the food article.
• Planned shipment information (if food has not yet been sent): Anticipated date of shipment and expected US port of entry, if the food has not yet departed at the time of Prior Notice submission.

How to File FDA Prior Notice: PNSI vs ACE/ABI

FDA Prior Notice must be submitted electronically. There are two authorized filing systems, and you must use one or the other. Paper submissions are not accepted under the current regulation.

Step-by-Step: How Prior Notice Is Filed in Practice

1. Gather required shipment information: collect FDA product code, manufacturer details with registration number, shipper and importer information, bill of lading number, anticipated arrival date and port, and container or tracking number.
2. Identify the correct FDA product code: use the PNSI product code wizard at fda.gov to categorize the shipment correctly.
3. Choose your filing system (PNSI or ACE/ABI): file through ACE/ABI when working with a broker/forwarder; use PNSI for self-filing or international mail.
4. Submit the Prior Notice and receive the PN Confirmation Number: FDA reviews and confirms; the PN Confirmation Number must accompany the food upon arrival.
5. Verify confirmation against your filing deadline: ensure the PN Confirmation Number is received before the mode-specific deadline (8 hours for ocean freight).
6. Ensure the PN Confirmation Number accompanies the shipment: ABI/ACE submissions transmit electronically; PNSI submissions must be included on shipping documents.

Foods Exempt from FDA Prior Notice

Not every food imported into the United States requires Prior Notice. The FDA regulation at 21 CFR 1.277 lists specific categories of food that are exempt from the Prior Notice requirement. These exemptions are narrow and specific. If your food product does not clearly fall within one of these categories, you should assume that Prior Notice is required.

A particularly important clarification for US food importers is the USDA scope limitation. Meat, poultry, and egg products regulated exclusively by the USDA Food Safety and Inspection Service (FSIS) are not subject to FDA Prior Notice. However, these products are subject to their own USDA import compliance requirements, including reinspection at USDA-approved import inspection houses, FSIS import certificates, and country-of-origin labeling requirements. If your shipment includes both USDA-regulated products and FDA-regulated food products, Prior Notice is required for the FDA-regulated items.

Consequences of Non-Compliance with FDA Prior Notice

The consequences of failing to submit FDA Prior Notice, submitting it late, or submitting inaccurate or incomplete information are severe and immediate. This is not a regulation where minor paperwork deficiencies result in a warning letter. Under Section 301(ee) of the FD&C Act, importing food in violation of the Prior Notice requirements is explicitly classified as a prohibited act.

Shipment Refusal at Port of Entry

The most immediate consequence of non-compliant Prior Notice is that the food shipment is refused entry into the United States at the port of arrival. A refused shipment cannot be released into US commerce. The importer must either re-export the entire shipment from the United States within a specified timeframe, or destroy the shipment under FDA and CBP supervision. Both outcomes are at the importer's expense, which for a full ocean freight container can represent tens or hundreds of thousands of dollars in cargo value plus re-export and destruction costs.

FDA Hold

In addition to outright refusal, the FDA can place a hold on a shipment pending examination, requiring the importer to respond to FDA requests for additional information, submit corrected Prior Notice, or present the cargo for physical inspection before any release determination is made. During an FDA hold, the importer continues to incur port storage and demurrage charges.

Post-Refusal and Post-Hold Resubmission Timeframes

The 2025 regulatory amendment clarified the timeframes for Prior Notice resubmission after a refusal or hold notice. Under the updated rule, the clock for submitting post-refusal Prior Notice starts from the date FDA issues the response to a request for FDA review. Importers who wish to challenge a refusal must act within the specified window or lose the opportunity for the FDA to reconsider the entry.

FDA Prior Notice and Food Facility Registration

FDA Prior Notice and FDA Food Facility Registration are two separate but closely interconnected requirements. Understanding how they relate is essential for food importers to ensure full compliance.

What Is FDA Food Facility Registration?

Under 21 CFR Part 1, Subpart H, any facility that manufactures, processes, packs, or holds food for consumption in the United States must register with the FDA. This includes foreign facilities that export food to the United States. Registration must be renewed biennially during the October-December window in even-numbered years. Facilities that fail to renew their registration have their registration suspended, which effectively prohibits the import of food from that facility into the United States.

How Registration Connects to Prior Notice

When a food facility is registered with the FDA, its FDA registration number must be included in the Prior Notice submission for food produced, processed, or packed at that facility. This linkage allows the FDA to cross-reference the Prior Notice against the facility's registration status and compliance history.

If a food manufacturer's FDA registration has expired or been suspended, food from that facility cannot legally be imported into the United States. This is a compliance risk that importers must monitor for their foreign suppliers on an ongoing basis, not just at the time of an initial supplier approval. Importers should build registration verification into their supplier onboarding and annual review processes.

FDA Prior Notice in the Broader US Food Import Compliance Picture

Prior Notice is one component of a broader US food import compliance framework. Commercial food importers are subject to multiple overlapping regulatory requirements, and understanding how Prior Notice fits within that framework is important for building a compliance program that holds up under FDA scrutiny.

The Full US Food Import Compliance Stack

In addition to FDA Prior Notice, food importers are responsible for the following:

• FDA Food Facility Registration (21 CFR Part 1, Subpart H): facilities manufacturing, processing, packing, or holding food for US consumption must register and renew biennially; Prior Notice submissions must reference the facility's active registration number.
• Foreign Supplier Verification Program (FSVP): under FSMA, US importers must verify foreign suppliers produce food meeting US food safety standards (importer obligation, not the customs broker's).
• CBP Entry and Customs Documentation: standard CBP entry, commercial invoice, packing list, and bill of lading; for most commercial shipments, entry and Prior Notice are submitted together through ACE/ABI via a licensed customs broker.
• USDA Requirements for Specific Categories: meat, poultry, and processed egg products regulated by USDA FSIS require separate USDA import inspections and are not subject to FDA Prior Notice, though they have their own pre-arrival notification requirements.
• Labeling Compliance: imported food products must comply with FDA labeling requirements under the Fair Packaging and Labeling Act and 21 CFR Part 101.

Prior Notice in the Context of Refrigerated Food Imports

For importers of refrigerated food, the stakes of a Prior Notice failure are compounded by the perishable nature of the cargo. A refused or held reefer container is not just a paperwork problem. It is a potential cargo loss event if the port hold extends beyond the product's shelf life. The combination of correct Prior Notice filing, verified food facility registration, and proactive FDA communication is therefore not merely a compliance checkbox for refrigerated food importers. It is a direct cargo protection measure.

Understanding how refrigerated cargo moves internationally, including the full documentation and compliance requirements at origin and destination, is covered in IGL's guide on how to ship reefer containers internationally. While IGL does not provide FDA Prior Notice filing or customs brokerage as a service, IGL coordinates closely with licensed customs brokers on behalf of clients to ensure that the logistics and compliance timelines align across every ocean freight and refrigerated cargo shipment.

Choosing the Right Customs Broker for Food Import Compliance

FDA Prior Notice is typically filed by a licensed customs broker, not a freight forwarder. When selecting a customs broker for food imports, verify that they have specific experience with FDA-regulated commodities, that they file through ACE/ABI as standard practice, that they understand the FDA product code system and can correctly classify each food article, and that they have an established process for monitoring FDA examination notices and responding to holds on behalf of the importer.

If you are a licensed NVOCC or freight forwarder handling food imports on behalf of clients, your obligation is to understand the full regulatory context of each food category you move and to ensure your clients are working with a customs broker equipped to handle the FDA compliance requirements for their specific commodity.
