You must submit Prior Notice to the U.S. FDA for most food, dietary supplements, and animal feed before those products enter or transit the United States, and failure to do so can stop your shipment at the border.
This post US FDA Prior Notice will show what information you need to provide, the timing rules by transport mode, and practical steps to file correctly so you avoid delays, fines, or refusal of entry.
You will get clear guidance on regulatory requirements, how to complete submissions, and the common compliance issues that cause holds—so you can keep your supply chain moving.
Regulatory Requirements for Importers
You must provide advance information about each food shipment and follow FDA filing rules, including who files and when. Accurate data, correct timing, and use of accepted electronic systems determine whether your shipment clears or faces holds, refusals, or penalties.
Who Must Submit Notifications
You are responsible for prior notice when you are the importer of record, or when you arrange to bring food into the United States. This includes food for humans and animals, dietary supplements, and certain cosmetics and feeds regulated by FDA. If you use a customs broker, freight forwarder, or agent, you can authorize them to file on your behalf, but you remain accountable for accuracy and timeliness.
Provide identifying details for your company and the shipment: consignee name, shipper, country of origin, product identity, quantity, and anticipated U.S. arrival. If multiple parties share responsibilities, clearly document who submits the notice and retains proof of submission.
Submission Timeframes and Methods
You must submit prior notice before the food arrives at the U.S. border. Time limits vary by transport mode:
- Land (including rail): before arrival at the first U.S. point of entry.
- Sea and air: within time windows defined in 21 CFR Part 1 (commonly hours before arrival or loading).
Use FDA-accepted electronic channels to file:
- Prior Notice System Interface (PNSI), or
- Automated Commercial Environment (ACE) via ABI, or
- Approved third-party systems or authorized agents.
Include planned shipment information and update or resubmit if confirmed details change after FDA acceptance. Keep submission confirmation and transaction IDs for your records to resolve inspections, holds, or compliance questions.
Compliance Procedures and Common Issues
You must file accurate electronic notifications before FDA-regulated food, supplements, animal feed, or certain cosmetics enter the United States. Timely filing, correct shipment identifiers, and consistent paperwork with customs systems are the most common sticking points.
Required Documentation
You need to submit a Prior Notice that includes shipment details and specific identifiers. Required elements typically are:
- Importer/consignee name and U.S. address.
- Manufacturer name and address (or grower/processor if applicable).
- Common or usual name of the article and quantity.
- Country of origin and country from which article is shipped.
- Shipment arrival method and expected arrival date.
- Container identification (e.g., bill of lading number, airway bill) and carrier name.
Keep documentation consistent across systems. Match the Prior Notice exactly to your ACE/ABI entry, ISF (if sea), and commercial invoice to avoid mismatches. Save confirmation numbers and timestamps from the PNSI or ACE portal; include them in your internal shipment file.
Consequences of Non-Compliance
If you fail to file or file incorrect Prior Notice, FDA can refuse admission of the shipment, detain goods, or assess civil penalties. Refusals often result in costly re-export or destruction and cause delays at ports that can exceed days or weeks.
Errors that commonly trigger enforcement include wrong arrival dates, missing manufacturer details, and mismatched container IDs between Prior Notice and customs filings. Repeated violations increase the chance of higher fines and more invasive inspections. You should track corrective actions, train staff on filing timelines, and use licensed brokers or customs brokers to reduce human error.
