The most expensive U.S. Agent mistakes come from confusing it with the other "agents" and "importers" you also have to name. Let's untangle them.
Foreign companies often have to name several different "agents" and "importers." They are not interchangeable — here's what each one actually is:
| Role | What it is | When it applies |
|---|---|---|
| U.S. Agent | FDA's U.S. contact for a foreign facility's registration | Foreign food, drug, device, cosmetic facilities |
| FSVP Importer | U.S. owner/consignee that verifies foreign food suppliers | Food imports (21 CFR Part 1, L) |
| Importer of Record | Customs party responsible for the entry & duties | All imports (a CBP role, not FDA) |
| Official Correspondent | Handles device registration & listing matters in FURLS | Devices (21 CFR 807) |
| Initial Importer | Importer that furthers marketing of a device; registers itself | Devices |
| Distributor / partner | A commercial relationship — can serve as agent, but with conflicts | Optional, not recommended as agent |
Acts as FDA's domestic contact; helps FDA communicate with the foreign facility; answers questions about the facility's imported products; assists with scheduling inspections. If FDA can't reach the facility directly, delivering information to the U.S. Agent counts as delivering it to the facility.
Guarantee your compliance or assume product liability; make your product "FDA approved." For devices, the U.S. Agent has no responsibility for adverse-event (MDR) reporting or submitting 510(k) premarket notifications — those stay with you.
Because the whole point of the role is reachability, reliability matters more than anything. What to look for:
A real U.S. physical address; genuine availability during U.S. business hours; independence from your distributor; prompt consent verification; experience across your product category; and continuity so you're never left without an agent.
A distributor with competing interests; anyone using a P.O. box; an agent who's slow to confirm consent or answer FDA; and anyone implying that being your U.S. Agent means FDA has "approved" your product.
| Category | U.S. Agent | Notes |
|---|---|---|
| Food & beverage | Required for foreign facilities | Maintained through biennial renewal |
| Drugs | Required for foreign establishments | Part of annual establishment registration |
| Medical devices | Required (21 CFR 807.40) | Plus an Official Correspondent for registration/listing |
| Cosmetics (MoCRA) | U.S. contact generally needed | Confirm current MoCRA requirement for your case |
Verify your facility is foreign and registering in a category that requires a U.S. Agent — food, drug, device, or cosmetic.
Real U.S. address (no P.O. box), reachable during business hours, and independent of your distributor.
Enter the agent's name, address, phone, and email in the FDA system as part of initial or updated registration.
Ensure the agent responds to FDA's automated email confirming consent — no reply within 10 business days can affect registration.
Report any change to the agent's name, address, or phone within 10 business days, and update at each renewal.
Keep the agent reachable so FDA communications and inspection scheduling are handled promptly all year.

A U.S.-based person or business that a foreign FDA-registered facility must designate as its domestic contact with FDA — helping FDA communicate with the facility, answering questions about its imported products, and assisting with inspection scheduling. It's tied to the facility's registration, not a shipment.
No. A U.S. Agent is the contact for a foreign facility's registration; an FSVP importer is the U.S. owner/consignee that verifies foreign food suppliers under FSVP. Different purposes, different rules — even if one person fills both.
No. Importer of record is a customs term for the party responsible for the entry and duties. A U.S. Agent is an FDA registration contact for a foreign facility.
For devices, the U.S. Agent (mandatory under 21 CFR 807.40) is FDA's U.S. contact point, while the Official Correspondent handles registration and listing matters in FURLS. They can be the same person or different — combining them is optional; having a U.S. Agent is required.
No. For devices, an Initial Importer furthers the marketing of a device from the foreign manufacturer to the ultimate consignee and must itself register. That's separate from designating a U.S. Agent.
Yes — foreign facilities registering in food, drug, device, and (under MoCRA) cosmetic categories must designate one. Domestic U.S. facilities do not.
Only if you have a U.S.-based person or business to serve. A foreign company with no U.S. presence can't act as its own agent — the agent needs a real U.S. address and must be reachable during business hours.
They can, but many companies avoid it. A distributor has its own interests, may not prioritize your FDA communications, and if the relationship ends you can lose your agent overnight. An independent provider avoids those conflicts.
No. FDA requires a real U.S. physical address, not a P.O. box, because the agent must actually receive communications during business hours.
After you list an agent, FDA emails them to confirm consent. If they deny consent — or don't respond within 10 business days — FDA notifies the facility and your registration can be affected. A responsive, professional agent avoids this.
Only one per foreign establishment. If you operate multiple facilities, each has its own designation — though one provider can serve as agent across all of them.
Serves as FDA's domestic contact: assisting communication with the facility, answering questions about its imported products, and helping schedule inspections. If FDA can't reach the facility directly, delivering information to the agent counts as delivering it to the facility.
It's a liaison, not a guarantor of your compliance. For devices, the U.S. Agent has no responsibility for adverse-event (MDR) reporting or submitting 510(k) notifications, and it doesn't assume product liability.
No. Having a U.S. Agent is part of registration, and registration is not FDA approval or endorsement. The role is purely about being FDA's contact point.
Yes — you can update your registration to name a new agent at any time, and changes to the agent's name, address, or phone must be reported to FDA within 10 business days. Many companies switch when an agent proves unresponsive.
Yes — foreign food facilities must designate one as part of registration, maintained through the biennial renewal. See our food facility registration service.
Yes — foreign drug and device establishments must each designate one at registration. Device establishments also work with an Official Correspondent for registration and listing.
Foreign cosmetic facilities registering under MoCRA generally need a U.S. contact. As MoCRA is relatively new, confirm the current requirement for your situation before registering.
