ImmutablePrior Notice is an FDA requirement established by the Bioterrorism Act of 2002. It requires advance notification to FDA of any food (including animal feed) imported or offered for import into the United States. The purpose is to give FDA advance information about imported food shipments for risk assessment and to help respond to potential food safety or bioterrorism threats.
Every shipment of food entering the United States requires Prior Notice - there are no dollar value minimums or quantity exceptions. Even small personal shipments and samples require Prior Notice unless specifically exempted.

The timing of your Prior Notice filing depends on how the food is being transported. FDA has set minimum advance notification requirements based on the mode of transportation:
Water (Sea)
8 hours
Before arrival at the US port of entry
Air
4 hours
Before arrival at the US port of entry
Road/Rail
2 hours
Before arrival at the US port of entry
International Mail
4 hours
Before arrival at the US port of entry
Mail tracking number required from Oct 1, 2026
Maximum Filing Time
Prior Notice cannot be filed more than 15 days before the anticipated date of arrival. If you file too early and the shipment is delayed beyond 15 days from your original filing, you may need to cancel and refile.
Important Timing Note
The timing requirements are based on when the food will ARRIVE, not when it departs. Calculate your filing deadline based on the estimated arrival time at the US port of entry, not when the shipment leaves the foreign country.
New Rule: Mail Tracking Numbers Required (Oct 1, 2026)
Effective October 1, 2026, food shipments arriving by international mail must include a mail tracking number in the Prior Notice submission. This new requirement was published in the Federal Register (2025-18655) and amends 21 CFR Part 1, Subpart I. Importers using international mail should begin collecting tracking numbers from postal services now to ensure compliance by the effective date.

CAPA Deployed
Assurentry auto-generates a 15-day response plan with acceptable corrective actions.
There are two primary methods for filing Prior Notice with FDA:
FDA Prior Notice System Interface (PNSI)
The FDA's web-based interface allows direct Prior Notice submission:
- Accessible through FDA Industry Systems
- Free to use
- Suitable for low-volume importers
- Confirmation number provided immediately upon submission
Automated Broker Interface (ABI)
For high-volume importers, Prior Notice can be filed through the Customs and Border Protection ABI system:
- Integrated with customs entry filing
- More efficient for large volumes
- Requires ABI certification
- Typically used through customs brokers
What Happens After Filing Prior Notice?
Automated Extraction
Our systems parse complex FDA documents into actionable data instantly.
Upon successful Prior Notice submission, you receive a Prior Notice Confirmation Number. This number is critical:
- Must be provided to CBP at the time of entry or arrival
- Links the food shipment to the Prior Notice filing
- Required for the food to be released
Confirmation Status
Prior Notice confirmations have two possible statuses:
- Confirmed: The Prior Notice has been accepted and the article may be offered for import
- Confirmed: Additional Review Needed: FDA needs to review the shipment further (this doesn't mean the shipment will be refused)
What Are the Most Common Prior Notice Errors?
Avoid these frequently made mistakes that can delay your shipments:
Wrong FDA Product Code
Using an incorrect or outdated FDA product code for the food
Prevention: Verify product codes using FDA's Product Code Builder before filing
Missing Registration Number
Not providing the FDA registration number for registered facilities
Prevention: Confirm registration numbers with foreign suppliers before shipment
Timing Violations
Filing too early (>15 days) or too late (after minimum window)
Prevention: Calculate arrival times carefully and set reminders for filing windows
Incomplete Information
Missing required fields like shipper address or manufacturer details
Prevention: Use a checklist to ensure all required information is gathered before filing
Mismatched Information
Prior Notice information doesn't match customs entry data
Prevention: Coordinate with customs broker to ensure consistency across filings
Who Is Exempt from Prior Notice Requirements?
Certain foods are exempt from Prior Notice requirements:
- Food for personal use: Food in personal baggage accompanying an individual arriving in the US (with some restrictions)
- Diplomatic pouches: Food transported in official diplomatic pouches
- Meat, poultry, and egg products: Products under USDA jurisdiction (these have separate USDA requirements)
- Transshipments: Food that remains in the same conveyance through the US without being unloaded
What Happens If I Don't File Prior Notice?
Failure to submit Prior Notice or submitting inaccurate Prior Notice can result in serious consequences:
- Refusal of admission: Food may be refused entry into the United States
- Detention: Food may be held pending resolution
- Re-exportation costs: Non-compliant shipments must be exported at importer's expense
- Potential destruction: If not re-exported within timeframes, food may be destroyed
- Future scrutiny: Repeated violations may increase scrutiny of future shipments
How Can High-Volume Importers Streamline Prior Notice?
If you regularly import food products, these strategies can streamline your Prior Notice process:
Use Established Templates
For regular shipments of the same products, create templates in the PNSI system with pre-filled information. Only update variable data like dates and quantities.
Work with Your Customs Broker
Most customs brokers file Prior Notice as part of their entry services. Establish clear communication channels and provide them with accurate product and supplier information.
Maintain Supplier Information Database
Keep an updated database of:
- Foreign supplier FDA registration numbers
- Complete addresses for manufacturers and shippers
- FDA product codes for all products you import
- Historical shipment data for reference
Consider Third-Party Software
Various compliance software solutions integrate Prior Notice filing with your supply chain management, automating much of the process.
