Medical Device U.S. Agent
Who needs a U.S. Agent, what the role covers (and doesn't), and how it differs from an importer or official correspondent.
Key Takeaways
- Required for every foreign device establishment — any class, under 21 CFR 807.40.
- One U.S. Agent per establishment — physically in the U.S., no PO box.
- The agent must consent — via FDA's process; no response in 10 business days = designate another.
- Limited role — communications, questions, inspection scheduling, receiving documents.
- Not MDR, not 510(k), not legal owner — the agent facilitates FDA contact only.
- Distinct from Official Correspondent & Initial Importer — though one party can wear several hats.
Who Needs a U.S. Agent — and the Requirements
- Every foreign device establishment — manufacturer, contract manufacturer, specification developer, repacker/relabeler, or foreign initial importer, for any device class
- Physically in the U.S. — a valid U.S. physical address (no PO box), available during business hours
- One per establishment — a single U.S. Agent on file (one agent can serve many establishments)
- Must consent — FDA's automated process confirms the agent agreed; no response within 10 business days means you must name another
- Keep it current — report any change in the agent's name, address, or phone to FDA within 10 business days
What a U.S. Agent Does — and Doesn't
| The U.S. Agent DOES | The U.S. Agent does NOT |
|---|---|
| Assist FDA in communications with the foreign establishment | Report adverse events (MDR, 21 CFR Part 803) |
| Answer FDA questions about the establishment's imported devices | Submit 510(k) premarket notifications |
| Assist FDA in scheduling inspections | Submit other regulatory applications |
| Receive FDA info/documents if FDA can't reach the establishment | Take legal responsibility for the device |
U.S. Agent vs Official Correspondent vs Initial Importer
| Role | What it is |
|---|---|
| U.S. Agent | FDA's U.S.-based contact for the foreign establishment (communications, questions, inspections, receiving documents) |
| Official Correspondent | Facilitates communication between the establishment's management and FDA for registration/listing matters |
| Initial Importer | The U.S. entity that first receives the imported device; has its own registration/listing obligations |
No Valid Agent, No Registration
- Registration prerequisite — you can't complete establishment registration without a designated, consenting U.S. Agent
- Import gate — a device generally can't be imported/offered for import unless it's listed and made at a registered foreign establishment; non-compliance can mean detained or refused shipments
- Responsiveness is the point — FDA communications and inspection scheduling flow through the agent; an unreachable agent (no backup, on vacation) creates real gaps
- Losing your agent — if the agent resigns or lapses, promptly designate a replacement to avoid a registration gap
Common U.S. Agent Mistakes
- Using a PO box or an address without a real U.S. presence
- Naming an agent who never consents — the designation fails after 10 business days
- Assuming the agent handles MDR or 510(k)s — it doesn't
- An unresponsive agent with no business-hours/backup coverage
- Not updating FDA within 10 business days when the agent's details change
- Treating "has a U.S. Agent" as "FDA-approved" in marketing

Frequently Asked Questions — Device U.S. Agent
1. What is a medical device U.S. Agent?
A U.S. Agent is a U.S.-based contact that a foreign medical device establishment must designate as part of FDA establishment registration (21 CFR 807.40). The U.S. Agent is FDA's point of contact for that foreign establishment - the person or company FDA reaches to communicate with it. It's a required piece of registration for any foreign device establishment, and its role is specifically defined (and limited) by the regulation.
2. Who needs a U.S. Agent?
Every foreign establishment that manufactures, prepares, propagates, compounds, or processes a device imported (or offered for import) into the U.S. must designate a U.S. Agent - regardless of the device's risk class. That includes foreign manufacturers, contract manufacturers, specification developers, repackers/relabelers, and initial importers located abroad. Domestic (U.S.) establishments don't need a U.S. Agent; it's specifically a requirement for foreign establishments.
3. What does a U.S. Agent actually do?
The role is limited by 21 CFR 807.40 to: assisting FDA in communications with the foreign establishment; responding to FDA questions about the establishment's devices that are imported or offered for import; assisting FDA in scheduling inspections of the foreign establishment; and receiving information or documents from FDA if the agency can't reach the foreign establishment directly or expeditiously (which is treated as equivalent to reaching the establishment). That's the defined scope.
4. What does a U.S. Agent NOT do?
Per FDA, the U.S. Agent has no responsibility for reporting adverse events under the Medical Device Reporting regulation (21 CFR Part 803) or for submitting 510(k) premarket notifications (21 CFR Part 807, Subpart E). The U.S. Agent also doesn't submit other regulatory applications and doesn't take legal responsibility for the device. Its role is strictly to facilitate FDA communication - not to be the regulatory or legal owner of the product. Don't assume your agent handles MDR or submissions.
5. Can I have more than one U.S. Agent?
No. Each foreign establishment designates only one U.S. Agent (21 CFR 807.40(b)). A single agent can, however, serve multiple foreign establishments, and a foreign establishment may designate its U.S. Agent to also act as its Official Correspondent. But for any one establishment there is exactly one U.S. Agent on file at a time.
6. What are the address requirements for a U.S. Agent?
The U.S. Agent must be physically located in the United States with a valid U.S. physical address - a PO box is not acceptable - and must be available during normal business hours. The agent can be an individual or a business (an importer, a consultant, a law firm, or a dedicated U.S. Agent service), as long as it meets the U.S.-presence and availability requirements and can reliably receive and forward FDA communications.
7. Does the U.S. Agent have to agree to the role?
Yes. FDA uses an automated process in which the designated U.S. Agent must confirm that it agrees to act in that capacity. If the designated agent denies consent - or doesn't respond within 10 business days - the foreign establishment is notified and must designate a new U.S. Agent to satisfy the requirement. So you can't simply name someone; the agent has to accept the designation.
8. What's the difference between a U.S. Agent and an Official Correspondent?
The Official Correspondent facilitates communication between the foreign establishment's management and FDA for matters relating to registration and device listing. The U.S. Agent is FDA's U.S.-based contact for the foreign establishment more broadly (communications, questions about imported devices, scheduling inspections, receiving documents). They can be the same party - a foreign establishment may designate its U.S. Agent to also act as the Official Correspondent - but they are distinct roles.
9. Is the U.S. Agent the same as the Initial Importer?
Not necessarily. The Initial Importer is the U.S. entity that first receives the imported device; it has its own registration/listing obligations. The U.S. Agent is FDA's designated contact for the foreign establishment. One party can serve as both, but they are separate roles with separate purposes - and a foreign establishment identifies both its U.S. Agent and any importer(s) in its registration information.
10. What happens if the U.S. Agent's details change?
The foreign establishment or the U.S. Agent must report any change in the U.S. Agent's name, address, or phone number to FDA within 10 business days of the change (21 CFR 807.40). Keeping this current matters, because FDA relies on the U.S. Agent's contact details to reach the establishment - stale information can mean missed communications and compliance gaps.
11. What happens without a valid U.S. Agent?
A foreign establishment can't complete FDA establishment registration without a designated (and consenting) U.S. Agent, and a device generally may not be imported or offered for import unless it is listed and manufactured at a registered foreign establishment. In practice, without compliant registration and a valid U.S. Agent, shipments can be detained or refused at import. Losing your agent (e.g., they resign) without promptly replacing them creates the same exposure.
12. Does having a U.S. Agent mean my device is FDA-approved?
No. A U.S. Agent is a registration-related contact requirement - it has nothing to do with clearance or approval. Registration and listing (and having a U.S. Agent) don't mean FDA cleared or approved your device, and implying otherwise is misleading. Your device still needs the correct premarket pathway (exempt, 510(k), De Novo, or PMA) where required. The U.S. Agent facilitates communication; it doesn't confer any FDA authorization.
13. Can my distributor or importer be my U.S. Agent?
They can, if they're U.S.-based, meet the requirements, and consent - but consider whether that's wise. A U.S. Agent needs to be responsive to FDA during business hours and reliably forward communications; a busy distributor may not be set up for that. Some companies prefer an independent, dedicated U.S. Agent to avoid conflicts of interest and ensure FDA communications and inspection scheduling are handled promptly and neutrally.
14. Why does responsiveness matter for a U.S. Agent?
Because FDA communications - including inspection scheduling and questions about your imported devices - flow through the U.S. Agent, and if FDA can't reach the establishment directly, giving documents to the agent counts as giving them to you. An unresponsive agent (on vacation, unreachable, or without backup coverage) can mean missed FDA deadlines, delayed inspections, and compliance problems you don't learn about until it's too late. Continuous business-hours availability is the point.
15. Do domestic (U.S.) manufacturers need a U.S. Agent?
No. The U.S. Agent requirement under 21 CFR 807.40 applies to foreign establishments. A domestic manufacturer registers and lists (and complies with the quality system, labeling, and MDR requirements) but doesn't designate a U.S. Agent, since FDA can reach it directly in the United States. The requirement exists specifically to give FDA a reliable U.S. contact for establishments located abroad.
