The short answer
Food samples are not exempt from FDA rules just because they are free, small or for a trade show. FDA’s Prior Notice Q&A (Edition 4, October 2023) is clear: there is no exemption for research or test-marketing samples, and trade samples carried in by a traveler are commercial, not personal. If the sample is an article of food — a can of juice, a box of biscuits, a bag of spice — it needs Prior Notice before it arrives.
There are narrow exceptions: samples that are not food in form (for example a lab slurry), and quality-assurance or research samples that are fully used up or destroyed may fall under FDA enforcement discretion. Plan on filing Prior Notice for anything that looks like food.
Prior Notice for samples: the basics
| How the sample travels | File Prior Notice at least… |
|---|---|
| Road (truck, car) | 2 hours before arrival |
| Air or rail | 4 hours before arrival |
| Sea | 8 hours before arrival |
| Express courier (DHL, FedEx, UPS) | The deadline for the transport mode (usually air: 4 hours) |
| International mail (postal) | Before the package is sent — and the confirmation number goes on the customs declaration |
Through FDA’s Prior Notice System Interface, Prior Notice can be filed no more than 15 calendar days before arrival (30 days through CBP’s ACE). The clock only starts once FDA confirms the submission.
What happens without Prior Notice
Food arriving without adequate Prior Notice is refused admission and held — at the port or in a secure facility — and cannot be delivered to the importer. For a trade show, that usually means the samples never reach the booth.
Registration and FSVP for samples
- Prior Notice details: for processed food, Prior Notice asks for the manufacturer’s name and FDA food facility registration number. If you cannot give the registration number, you must give the manufacturer’s full name and address and the reason.
- FSVP: food imported for research or evaluation is exempt from FSVP if it is not for sale or distribution to the public, is labeled as food for research or evaluation use, is a small quantity used only for research, analysis or quality assurance, and is declared as such to CBP at entry. Samples handed out to visitors at a trade show are distributed to the public, so do not assume this exemption covers them.
- Labels: samples given to the public should carry a compliant English label. Unlabeled samples invite questions at entry.
Example: snacks for a trade show in Las Vegas
A snack maker in Thailand sends 20 cartons of chips by air courier for a U.S. trade show where visitors will taste them. It files Prior Notice (at least 4 hours before arrival) with its FDA facility registration number, makes sure the courier has the confirmation number, and uses compliant U.S. labels. Because visitors will eat the samples, it does not rely on the FSVP research exemption — its U.S. importer or show agent handles FSVP.
Other product types
- Cosmetics: no Prior Notice, but FDA can still examine and detain cosmetic samples at entry. Labels should meet U.S. rules if samples go to the public.
- Medical devices and drugs: no Prior Notice, but entry rules apply. Devices for clinical study and drugs (including OTC drugs) have specific requirements — get advice before shipping.
- Personal gifts: food sent by an individual as a non-commercial gift is not subject to Prior Notice — but business samples are commercial.

Frequently asked questions
Do free food samples need FDA Prior Notice?
Yes, if they are articles of food. FDA’s Prior Notice Q&A says there is no exemption for research or test-marketing samples, and trade samples are commercial, not personal.
How early must I file Prior Notice for a courier shipment?
Courier shipments follow the deadline for the transport mode — usually air, so at least 4 hours before arrival.
Are trade show samples exempt from FSVP?
Not if they are given to the public. The FSVP research or evaluation exemption covers small quantities used only for research, analysis or quality assurance, not for distribution to the public, labeled and declared to CBP.
What if my samples arrive without Prior Notice?
They are refused admission and held at the port or a secure facility, and cannot be delivered.
