FDA regulates approximately 40% of all food consumed in the United States, plus drugs, medical devices, cosmetics, dietary supplements, and electronic products that emit radiation. If your imported product falls under FDA jurisdiction and you have not filed prior notice, registered your foreign facility, or maintained a Foreign Supplier Verification Program, your shipment can be detained, refused entry, or destroyed. FDA detentions operate on a different process and timeline than CBP holds, and many importers are blindsided by requirements they did not know applied to their products.
Key Takeaways
FDA regulates food, beverages, dietary supplements, drugs, medical devices, cosmetics, tobacco products, and certain electronic products. Approximately 40% of all food consumed in the U.S. is imported.
Prior notice must be filed with FDA before any food shipment arrives. For ocean shipments, prior notice must be submitted no later than 8 hours before arrival. For truck shipments, 2 hours. For air and rail, 4 hours.
Every foreign facility that manufactures, processes, packs, or holds food for U.S. consumption must be registered with FDA and must renew registration biennially.
The Foreign Supplier Verification Program (FSVP) requires every U.S. food importer to verify that foreign suppliers produce food meeting U.S. safety standards. FSVP is not optional and FDA is actively conducting inspections and issuing warning letters for noncompliance.
FDA import alerts allow detention of shipments without physical examination. If your product, supplier, or country of origin is listed on an import alert, every shipment is automatically detained.
FDA detentions can last weeks or months. During that time, goods cannot be sold, storage charges accumulate, and the importer bears all costs.
What Products Does FDA Regulate at Import?
FDA's jurisdiction at the border is broader than many importers realize. The following product categories require FDA compliance before they can enter U.S. commerce.
| Product Category | Key Requirements |
|---|---|
| Food and beverages | Prior notice, facility registration, FSVP, labeling compliance, HACCP (seafood/juice) |
| Dietary supplements | Prior notice, facility registration, FSVP (modified), cGMP compliance |
| Cosmetics | Facility registration (MoCRA), product listing, labeling, safety substantiation |
| Human drugs (Rx and OTC) | Drug registration, listing, cGMP, labeling, NDA/ANDA or OTC monograph |
| Medical devices | Device registration, listing, 510(k)/PMA as applicable, labeling |
| Animal food and feed | Prior notice, facility registration, FSVP, preventive controls |
| Tobacco products | Premarket authorization, registration, listing, labeling |
| Radiation-emitting electronics | Performance standards compliance, accession number reporting |
Key definition: Partner Government Agency (PGA) refers to federal agencies like FDA, USDA, EPA, and CPSC that have authority over specific product categories at the border. FDA is the PGA for the broadest range of imported consumer products.
If you are unsure whether your product falls under FDA jurisdiction, check before you ship. Discovering that FDA applies to your product after it has arrived at the port creates delays that are entirely preventable.
What Is Prior Notice and When Must It Be Filed?
Prior notice is a mandatory electronic notification that must be submitted to FDA before any food (including animal food) arrives in the United States. It provides FDA with advance information about the product, manufacturer, shipper, and anticipated arrival.
The short answer is: if you are importing food, you must tell FDA it is coming before it gets here. No prior notice means no entry.
| Mode of Transport | Prior Notice Deadline |
|---|---|
| Ocean vessel | No later than 8 hours before arrival at U.S. port |
| Truck | No later than 2 hours before arrival at U.S. border crossing |
| Air freight | No later than 4 hours before arrival at U.S. airport |
| Rail | No later than 4 hours before arrival at U.S. border crossing |
| International mail | Before the shipment arrives |
Prior notice can be filed through the FDA Prior Notice System Interface (PNSI) or through CBP's Automated Commercial Environment (ACE) as part of the entry filing process. The prior notice confirmation number must be linked to the customs entry.
Common prior notice errors that trigger holds include using generic FDA product codes that do not accurately describe the product, providing manufacturer information that does not match FDA facility registration records, and mismatches between product descriptions on the prior notice, the commercial invoice, and the product label.
What Is the Foreign Supplier Verification Program?
The Foreign Supplier Verification Program (FSVP) is a requirement under the Food Safety Modernization Act (FSMA) that places the burden on U.S. importers to verify that their foreign suppliers produce food in a manner that provides the same level of public health protection as U.S. food safety standards.
The short answer is: FSVP requires you to prove that the food you import is safe. It is not a one-time filing. It is an ongoing, documented program for every food product and every foreign supplier.
Under FSVP, importers must perform a hazard analysis for each food they import, evaluate the risk posed by each food and each supplier, determine and conduct appropriate verification activities (such as onsite audits, sampling and testing, or reviewing the supplier's food safety records), take corrective actions when problems are identified, and maintain records documenting all of the above.
At entry, the FSVP importer must be identified in ACE by name, email address, and unique facility identifier (DUNS number). If this information is missing or incorrect, FDA can hold the shipment.
FDA has significantly increased FSVP inspections since 2022. Inspectors visit importer facilities, review FSVP documentation, and issue warning letters for noncompliance. A warning letter can trigger import alerts that affect all future shipments from the cited suppliers. In February 2026, FDA issued warning letters to food importers for significant FSVP violations.
What Is an FDA Import Alert?
An FDA import alert is a published notice that instructs FDA field staff to detain shipments of specific products from specific countries, regions, or manufacturers without conducting a physical examination first. This mechanism is called Detention Without Physical Examination (DWPE).
The short answer is: if your product or supplier is listed on an import alert, every one of your shipments is automatically detained until you prove compliance.
Import alerts are FDA's primary tool for blocking noncompliant imports at scale. They are based on patterns of past violations, test results, inspection findings, or intelligence about specific products or origins. Once your product or supplier is on an alert, the burden shifts entirely to you to demonstrate that the specific shipment meets U.S. requirements before it will be released.
There are over 100 active import alerts covering products from dozens of countries. Common triggers include pesticide residues, undeclared allergens, Salmonella or Listeria contamination, unauthorized food additives or color additives, labeling violations, failure to meet cGMP (current Good Manufacturing Practice) requirements, and products from unregistered facilities.
What Happens During an FDA Detention?
When FDA detains your shipment, the goods cannot enter U.S. commerce. The process works as follows.
Notice of detention. FDA issues a notice to the importer (or their broker) explaining why the goods are being detained and what evidence is needed for release.
Response window. The importer typically has a limited time (often 10 to 20 business days) to submit evidence demonstrating that the goods comply with U.S. requirements. This may include laboratory test results, certificates of analysis, labeling corrections, or documentation showing the product is not the same as the one covered by the import alert.
FDA review. FDA evaluates the submitted evidence. If satisfied, the shipment is released. If not, FDA issues a Notice of Refusal, and the goods must be either re-exported or destroyed at the importer's expense.
Cost accumulation. During the entire detention period, the importer is responsible for storage costs at the port or warehouse. These charges accumulate daily and can become substantial for shipments held for weeks or months. The importer also bears the cost of any required laboratory testing, legal or consulting fees for preparing the response, and the commercial cost of delayed delivery to customers.
FDA detentions are separate from and in addition to any CBP holds. A single shipment could be held by CBP for classification or valuation issues and simultaneously detained by FDA for safety concerns. The two processes run on different timelines and require different responses.
What Are the Most Common FDA Detention Triggers?
1. No Prior Notice or Deficient Prior Notice
Filing prior notice late, with incorrect product codes, or with manufacturer information that does not match FDA records is one of the most frequent causes of FDA holds. This is entirely preventable with proper filing procedures.
2. Unregistered Foreign Facility
Every foreign facility that manufactures, processes, packs, or holds food for U.S. consumption must have an active FDA Food Facility Registration with a valid unique facility identifier (UFI). Facilities must renew registration biennially. If your supplier's registration has lapsed or was never completed, your shipment will be refused.
3. No FSVP or Inadequate FSVP
If FDA inspects your import operation and finds that you have no FSVP, or that your FSVP lacks required elements (hazard analysis, supplier evaluation, verification activities, documentation), FDA can issue a warning letter and place your suppliers on an import alert. This affects not just the current shipment but all future shipments from those suppliers.
4. Labeling Violations
U.S. food labeling requirements are extensive and differ from labeling rules in most other countries. Common violations include missing or incorrect nutrition facts panels, undeclared allergens, non-English labeling, unauthorized health claims, and net weight discrepancies. Products with labeling violations are considered misbranded and can be detained or refused.
5. Product Listed on an Active Import Alert
If your product category, country of origin, or specific manufacturer appears on an active FDA import alert, your shipment will be detained automatically. Importers should check the FDA import alert database before placing purchase orders with new suppliers.
How to Build an FDA-Ready Import Operation
1. Verify Facility Registration Before You Order
Before placing a purchase order with any foreign food supplier, confirm that their facility has an active FDA Food Facility Registration with a valid DUNS number. Check the registration status and the biennial renewal date. If the facility is not registered, your goods will not be admitted.
2. Build and Maintain Your FSVP
For every food product and every foreign supplier, maintain a documented FSVP that includes a written hazard analysis, a supplier evaluation, verification activities with supporting records, and corrective action procedures. This is not a one-time exercise. FSVP must be updated when suppliers change, when new hazards are identified, or when FDA issues new guidance.
3. File Prior Notice Accurately and On Time
Use specific FDA product codes, not generic ones. Verify that manufacturer and shipper information matches FDA registration records. Link the prior notice confirmation number to the customs entry. Build prior notice filing into your standard shipment preparation process, not as an afterthought when the vessel is already en route.
4. Check FDA Import Alerts Before Sourcing
Search the FDA import alert database for your product category, country of origin, and specific supplier. If any of these appear on an active alert, understand the basis for the alert and determine whether your specific products are covered before committing to the purchase.
5. Ensure U.S. Labeling Compliance Before Shipment
Review every product label against FDA requirements before the goods leave the foreign port. Correcting labeling at the border is expensive, time-consuming, and sometimes impossible. Work with your supplier to produce U.S.-compliant labels as part of the production process, not as a retrofit at the port.
6. Coordinate FDA and CBP Compliance Through Your Broker
Your customs broker handles the CBP entry, but FDA compliance requires additional data, documentation, and filing. Ensure your broker is equipped to handle PGA filing for FDA-regulated products, can transmit FSVP importer identification in ACE, and has processes for responding to FDA holds and detention notices. For related CBP compliance requirements, see our guides on HTS classification, ISF filing, and customs audits.
Frequently Asked Questions
What products does FDA regulate at import?
FDA regulates food and beverages, dietary supplements, drugs, medical devices, cosmetics, tobacco products, animal food, and certain electronic products that emit radiation. Approximately 40% of all food consumed in the U.S. is imported and subject to FDA oversight.
What is prior notice for FDA imports?
Prior notice is a mandatory electronic notification submitted to FDA before any food shipment arrives in the United States. It must be filed at least 8 hours before arrival for ocean shipments, 4 hours for air and rail, and 2 hours for truck. Failure to file results in automatic refusal of the shipment.
What is FSVP?
The Foreign Supplier Verification Program is a FSMA requirement that obligates U.S. food importers to verify that their foreign suppliers produce food meeting U.S. safety standards. Importers must perform hazard analyses, evaluate suppliers, conduct verification activities, and maintain documented records for each food and each supplier.
What happens if my shipment is detained by FDA?
The shipment cannot enter U.S. commerce. FDA issues a detention notice explaining the basis. The importer has a limited window to submit evidence of compliance. If FDA is not satisfied, the goods must be re-exported or destroyed at the importer's expense. Storage charges accumulate daily during the detention.
What is an FDA import alert?
An import alert instructs FDA field staff to detain shipments of specific products, origins, or manufacturers without physical examination. If your product or supplier appears on an import alert, every shipment is automatically detained until you demonstrate compliance.
Is FSVP required for dietary supplements?
Modified FSVP requirements apply to dietary supplement importers. Importers who comply with the dietary supplement cGMP regulation's specifications and verification requirements for components and packaging are deemed in compliance with most standard FSVP requirements, but must still identify the FSVP importer at entry.
Does FDA detention affect my CBP compliance?
FDA detention is separate from CBP holds, but both can affect the same shipment simultaneously. An FDA detention does not automatically trigger CBP penalties, but prolonged holds increase storage costs and can affect your overall CBP risk profile.
How do I check if my supplier is on an FDA import alert?
Search the FDA import alert database, which is publicly available on the FDA website. You can search by product type, country, or manufacturer. Check this database before placing purchase orders with new suppliers and periodically for existing suppliers.
How long can an FDA detention last?
There is no fixed maximum. Detentions can last days, weeks, or months depending on the complexity of the issue and the importer's ability to provide satisfactory evidence. During the entire period, the importer bears storage, testing, and administrative costs.
Do cosmetics have new FDA import requirements?
Yes. The Modernization of Cosmetics Regulation Act (MoCRA) introduced new requirements for cosmetic facility registration, product listing, safety substantiation, and adverse event reporting. Importers of cosmetics should verify that foreign facilities are registered and that products are listed with FDA.
Can my broker handle FDA compliance for me?
Your broker can file PGA message sets in ACE and transmit FSVP importer identification at entry, but the importer is legally responsible for maintaining the FSVP, ensuring facility registration, and meeting all FDA requirements. The broker facilitates the filing; the importer owns the compliance.
This guide reflects FDA import requirements and enforcement practices as of April 3, 2026. FDA regulations, import alerts, and FSVP requirements are updated regularly. Importers should verify current requirements through FDA.gov and consult with their customs broker or an FDA regulatory specialist for product-specific guidance. For related compliance topics, see our guides on CPSC eFiling, ISF filing, customs audits, and HTS classification errors.
