Which U.S. Agent Do I Need for FDA Registration?
A quick decision guide — answer two questions (are you foreign, and what do you make?) and you'll know which U.S. Agent registration you need.
Key Takeaways
- Same role across programs — "which agent" = "which program's registration."
- Only foreign establishments need one — domestic firms don't.
- One per program — food, drug, device, or cosmetic, by your product.
- Different renewal cadence — food/cosmetics biennial; drugs/devices annual.
- Multiple categories = one per program — one provider can cover all.
- Classify first — the category decides the program (and the agent).
Two Questions to Find Your U.S. Agent
- Is your establishment foreign (outside the U.S.)? If no — you don't need a U.S. Agent; FDA can reach a domestic firm directly. If yes — continue.
- Which FDA program(s) do your products fall under? Designate a U.S. Agent in each program's registration: food/supplement (biennial), drug (annual), device (annual), or cosmetic (biennial).
- More than one category? You need a U.S. Agent for each program's registration — but one provider can serve as your agent across all of them, on one coordinated calendar.
Pick the Program That Matches Your Product
| Your product | Program & rule | Renewal |
|---|---|---|
| Food / dietary supplement | Food facility (21 CFR 1.225–1.227) | Biennial |
| Drug (OTC or Rx) | Drug establishment (21 CFR 207.69) | Annual |
| Medical device | Device establishment (21 CFR 807.40) | Annual |
| Cosmetic | Cosmetic facility (MoCRA) | Biennial |
It's the Same Role — "Which" Means "Which Program"
You're not choosing between different kinds of U.S. Agent. The agent's job — being FDA's U.S.-based contact for your foreign establishment (facilitating communications, answering questions, helping schedule inspections, receiving documents) — is the same across food, drugs, devices, and cosmetics.
- What changes is the registration it's attached to — and that program's rule and renewal timing
- The agent's limited role and requirements (U.S.-based, available, consenting) are consistent
- So the real question is your category — get that right and "which agent" answers itself
Common "Which Agent" Mistakes
- Thinking there are different "types" of U.S. Agent — it's one role, by program
- Registering in the wrong program — because the product wasn't classified first
- Assuming one registration/agent covers multiple categories — it doesn't
- A domestic firm paying for a U.S. Agent it doesn't need
- Confusing the agent with a consultant — the agent won't do your compliance
- Treating the agent as "FDA approval"

Frequently Asked Questions — Which U.S. Agent
1. Which U.S. Agent do I need for FDA registration?
The U.S. Agent role is essentially the same across FDA programs - a U.S.-based contact for a foreign establishment - so "which U.S. Agent" really comes down to which program's registration applies to you. If your establishment is in the U.S., you don't need one. If it's foreign, you need a U.S. Agent for each FDA program your products fall under: food/supplement, drug, device, or cosmetic. Pick by your product and program; the role itself doesn't change.
2. Is there a different type of U.S. Agent for each program?
Not really - it's the same fundamental role (FDA's U.S. contact for a foreign establishment) governed by different regulations per program: food (21 CFR 1.225–1.227), drug (21 CFR 207.69), device (21 CFR 807.40), and cosmetics (MoCRA). The agent's function is the same everywhere; what differs is the program's registration rule and renewal cadence. So you're not choosing a "type" of agent - you're identifying which program(s) you register in and designating an agent there.
3. Do I even need a U.S. Agent?
Only if your establishment is foreign (located outside the United States). Foreign establishments must designate a U.S. Agent as part of FDA registration - you generally can't complete a foreign registration without one. Domestic (U.S.) establishments register but don't need a U.S. Agent, because FDA can reach them directly. So the first question in choosing "which" agent is really "do I need one at all?" - and that turns on whether you're foreign.
4. What if my product is food or a dietary supplement?
A foreign food or dietary-supplement facility needs a U.S. Agent designated in its FDA food facility registration (21 CFR 1.225–1.227), which renews biennially (every two years, in even years). See the food U.S. Agent page for the specifics. Note that dietary supplements are regulated as a category of food for these purposes, so the food facility registration/U.S. Agent framework applies.
5. What if my product is a drug (including OTC)?
A foreign drug establishment needs a U.S. Agent as part of drug establishment registration (21 CFR 207.69), which renews annually (October–December). This covers OTC and prescription drug establishments. See the drug/pharmaceutical U.S. Agent page for details. If you're not sure whether your product is a cosmetic or an OTC drug, sort that out first - it determines which program (and agent) applies.
6. What if my product is a medical device?
A foreign device establishment needs a U.S. Agent as part of device establishment registration (21 CFR 807.40), which renews annually (October–December). The device U.S. Agent has a specifically defined, limited role and a consent step. See the medical device U.S. Agent page. You'll also need to have classified the device and obtained any required 510(k)/PMA - registration and the agent don't replace that.
7. What if my product is a cosmetic?
A foreign cosmetic facility operates under MoCRA, which requires facility registration and product listing; a foreign facility designates a U.S. Agent as part of that. MoCRA facility registration renews biennially. See the MoCRA cosmetics U.S. Agent page. Watch the cosmetic/drug line: if your "cosmetic" makes drug claims or adds SPF, it's a drug, and the drug framework (and agent) would apply instead.
8. What if I sell products in more than one category?
Then you register in each applicable program and need a U.S. Agent for each foreign establishment/registration - they don't merge into one. For example, a foreign company with a supplement, an OTC drug, and a cosmetic would have registrations (and U.S. Agent designations) in the food, drug, and cosmetic programs, each on its own renewal cadence. One provider can serve as your U.S. Agent across all of them, which keeps it coordinated.
9. Can one U.S. Agent cover all my programs?
One provider can act as your U.S. Agent across food, drug, device, and cosmetic registrations, so you have a single point of contact and one coordinated renewal calendar. Technically each foreign establishment's registration lists a U.S. Agent, so the designation is made per registration - but it can be the same firm across all of them. That's usually the simplest setup for a company with products in multiple categories.
10. How do I actually pick the right one?
Two questions settle it: (1) Is your establishment foreign? If no, you don't need a U.S. Agent. (2) If yes, which FDA program(s) do your products fall under? Designate a U.S. Agent in each of those registrations. If you're unsure of the category (cosmetic vs OTC drug, or whether something is a device), resolve the classification first, because that determines the program - and therefore where you need the agent.
11. Does the U.S. Agent's role change by program?
The core role is consistent: the U.S. Agent facilitates FDA communication for the foreign establishment (communications, questions about the establishment's products, help scheduling inspections, receiving documents). Some programs (devices) have a formal consent step; renewal timing differs. But you're not getting a fundamentally different service by program - the agent's limited communication role is the same. What changes is the registration it's attached to.
12. Is a U.S. Agent the same as a consultant?
No. A U.S. Agent is the required FDA contact role; a consultant is the optional service that does your compliance work (registration, labeling, claims, classification, submissions). Choosing "which U.S. Agent" is about which program you register in - but separately, you may want a consultant to actually get the registration and compliance done. See our U.S. Agent vs consultant comparison to keep the two straight.
13. Does having the right U.S. Agent make me compliant?
No - it's necessary but not sufficient. Designating the correct U.S. Agent in the correct program's registration is one requirement, but you still need the registration itself done correctly, plus compliant labeling, lawful claims, and any premarket authorization for your product. A U.S. Agent is a contact point, not proof of compliance, and it's not FDA "approval." Get the agent right and the underlying compliance right.
14. What if I get the program wrong?
Registering in the wrong program (or designating an agent only there) leaves you non-compliant for the program you should be in - and can mean no valid registration/agent where it's actually required. That's why classification comes first: confirm whether your product is food, a drug, a device, or a cosmetic before you register and designate the agent. Getting the category right is what makes "which U.S. Agent" an easy question.
15. Where can I see the full U.S. Agent details?
Start with our FDA U.S. Agents hub, which explains the role, the requirements, and links to each program's dedicated U.S. Agent page (food, drug, device, cosmetics). This page is the quick "which one do I need" decision guide; the hub and program pages have the full detail. If you need registration and the agent handled together, see the combined registration and U.S. Agent compliance page.
16. How does FDA Registration Assistance help me choose and set it up?
We confirm whether you need a U.S. Agent at all (foreign vs domestic), classify your product to identify the right program(s), and act as your U.S. Agent in each applicable registration - food, drug, device, or cosmetic - with one coordinated renewal calendar if you have products in several categories. We can also complete the underlying registration and compliance. We're an independent compliance firm serving 1,000+ companies across 135+ countries with 15+ years of experience.
