Prior Notice is required for almost all food and animal feed imported or offered for import into the United States. Submit it electronically through ABI/ACE/ITDS or the FDA’s Prior Notice System Interface (PNSI) at access.fda.gov before the shipment arrives. Before anything else, confirm internally who is filing (you, your broker, or your agent), and once submitted, save the FDA confirmation number with your shipment paperwork. That single document travels with the load and answers most port-side questions before they get asked.

TL;DR:

Even small shipments like gifts and personal mail require FDA Prior Notice, regardless of whether they are commercial or low-value, and failure to file can delay entry.

The notice must include detailed information such as FDA product code, common name, estimated quantity, lot numbers when necessary, and countries of production; missing any of these can cause rejection.

Submitters must transliterate all non-Latin characters and confirm the correct FDA product code before filing; using unofficial forms can lead to incomplete or incorrect submissions.

Once confirmed, the FDA confirmation number must be stored with the shipment documents and presented at entry; updates or changes after confirmation require re-submission to avoid port holds.

The importer of record is legally responsible for accurate and timely filing, and working with licensed customs brokers ensures proper data entry and adherence to timing requirements.

What Is FDA Prior Notice and Which Shipments Need It

FDA Prior Notice is the advance electronic filing that tells the agency what food is entering the country, from where, and how, before it crosses the border. The scope is broader than most importers expect. It’s not limited to commercial pallets moving through a customs broker’s system.

The requirement covers food and animal feed for both humans and animals, regardless of whether the shipment is commercial. That means gifts and personal shipments carried through international mail also require Prior Notice, a detail that trips up a surprising number of first-time importers who assume “non-commercial” means “exempt.”

Here’s what falls inside the rule, and where the edge cases tend to live:

Commercial imports: any food article entering for sale, distribution, or processing.
Non-commercial shipments: personal food items, care packages, and samples sent by mail or courier.
Gifts: a jar of honey mailed to a relative counts the same as a container load.
Animal feed: pet food, livestock feed, and feed ingredients fall under the same requirement as human food.
Consolidated shipments: when multiple lots or suppliers are combined into one entry, each distinct food article generally needs its own line of data within the notice.
Small-value and de minimis entries: low-value shipments are not automatically excused from Prior Notice, even when they qualify for simplified customs entry types.

An “article of food” under FDA’s framework includes raw agricultural commodities, processed foods, dietary supplements, food additives, and animal feed components. “Imported or offered for import” covers the shipment from the moment it’s presented for U.S. entry, whether that’s at a land border, a seaport, an airport, or a postal facility. If you’re unsure whether a specific product line qualifies, treat it as covered. The penalty for over-filing is a few extra minutes of data entry. The penalty for under-filing is a shipment held at the port.

What Data Goes Into a Prior Notice (CFR-Aligned Checklist)

FDA Prior Notice isn’t a general description of your shipment. It’s a structured data submission with specific fields defined in 21 CFR §1.281, and missing even one required field is the most common reason a submission gets kicked back.

Here’s the field order that mirrors what FDA actually asks for:

Submitter and transmitter contact information — full name, address, and phone number for whoever is filing and whoever is transmitting the data.
Entry type and CBP entry identifier — the customs entry type code and the corresponding CBP entry number, when known at filing time.
FDA product code — the complete code, not an abbreviated or partial version.
Common or usual name of the food, matching the product code.
Estimated quantity, listed from the largest container size down to the smallest (for example, cases, then units within cases).
Lot or code numbers, when the product or its labeling requires them for traceability.
Manufacturer or grower identity, including registration number when the food is subject to facility registration.
Country of production and, where applicable, country from which the article is shipped.
Anticipated arrival information — port of entry, arrival date, and mode of transportation.

Prior Notice must include the complete FDA product code, common name, estimated quantity from largest to smallest container, and lot or code numbers when required. Miss the product code format and the whole submission can bounce, even if every other field is accurate.

Pro Tip: Build a standing data sheet that maps each SKU you regularly import to its FDA product code, transliterated product name, and lot number format. Reuse it for every shipment instead of rebuilding the field list from scratch each time.

Where and How to Submit Your Prior Notice

Most commercial entries go through ABI/ACE/ITDS, the same electronic system your customs broker likely already uses to file entry data with CBP. FDA PNSI, the standalone web portal at access.fda.gov, is the required path for international mail shipments and certain non-commercial or low-volume transactions that don’t run through a broker’s ABI connection.

Hands connecting network cable for electronic filing

Format rules apply regardless of channel. All submission data must use the Latin alphabet, and most fields must be entered in English. A supplier name printed in Cyrillic, Mandarin, or Arabic script on your invoice has to be transliterated before it goes into the system, and skipping that step is one of the more common causes of rejection.

Quick checks before you file:

Confirm the FDA product code against FDA’s own product code database, not a broker’s internal shorthand.
Transliterate every non-Latin name field, including manufacturer and grower names.
Run a test submission if your volume is high enough to justify one.
If ABI/ACE is down, fall back to FDA PNSI directly rather than waiting out the outage.

FDA also warns importers away from unofficial third-party “Prior Notice form” services that promise to file on your behalf outside these two channels. Data submitted through unofficial forms can be transmitted incorrectly or not reach FDA systems at all, which defeats the purpose of filing early in the first place.

Timing Rules and What Happens When Details Change

Prior Notice has to be confirmed by FDA before the shipment arrives, with the exact lead time varying by mode of transportation (a few hours for truck shipments moving short distances, longer for ocean freight). Once, FDA confirms your submission, you get a confirmation number. That number is not paperwork you file away and forget. It travels with the shipment and gets presented to CBP or port officials at entry, so keep it attached to your bill of lading or airway bill rather than buried in an email thread.

Here’s what to do when shipment details shift after confirmation:

Determine whether the change is material — a shift in quantity, arrival date, or shipper generally requires action; a minor administrative correction may not.
Resubmit through the original channel — if key information changes after confirmation, you must resubmit the prior notice or cancel it through the same system you used originally, per 21 CFR §1.282.
Document the cancellation and new confirmation in your shipment file so there’s a clean audit trail if a port official asks questions later.
Notify your broker or agent immediately if they filed on your behalf, since they’ll need to execute the resubmission on their end.

Skip this step and the consequences show up fast: FDA can refuse admission of the shipment, hold it at the port, or route it to inspection, any of which adds days and demurrage costs you didn’t budget for.

Who’s Legally Responsible, and the Mistakes That Get Filings Rejected

The importer of record carries legal responsibility for accurate, timely Prior Notice submission, even when a customs broker or freight forwarder files on their behalf. Handing the task to an agent doesn’t transfer the liability. It’s worth confirming in writing, before the first shipment, exactly who on your side or your agent’s side is hitting “submit.”

The rejection patterns repeat across nearly every importer we’ve seen struggle with this:

Using an incomplete or outdated FDA product code.
Leaving non-Latin characters in a manufacturer or product name field.
Omitting lot numbers on products where labeling requires them.
Filing duplicate notices for the same shipment through two different channels.

Pro Tip: Assign one named person, not “the logistics team,” to sign off on every Prior Notice before it’s transmitted, and store the confirmation number in the same folder as your commercial invoice and packing list. That one habit eliminates most of the scramble when CBP asks for it at the port.

How a Logistics Provider Supports Prior Notice Compliance

A licensed customs broker or freight forwarding partner handles the mechanical side of Prior Notice: mapping your SKUs to FDA product codes, running ABI/ACE connectivity, transliterating supplier and product names, and filing within the required window ahead of arrival.

What that support typically includes:

Product-code verification against FDA’s current database, not an outdated internal list.
Transliteration of names and addresses before submission.
Filing through ABI/ACE for commercial entries, with PNSI as backup for mail or edge-case entries.
Documented handoff of the FDA confirmation number to the importer of record.

Logistics providers and licensed brokers often integrate ABI/ACE filing directly into their systems, but the importer still needs to confirm who’s filing and keep the confirmation number in the shipment record. That confirmation should sit alongside the commercial invoice, not in a separate compliance folder nobody checks under deadline pressure.

A quick operational note

Get the product code right before you touch anything else. In practice, that’s the field that sinks the most filings. Save the FDA confirmation number the moment it arrives, and don’t wait for a port official to ask for it before you go looking. These aren’t complicated habits. They’re just the two that get skipped when a shipment is running late and someone decides paperwork can wait.
