FDA Registration for Foreign Manufacturers: U.S. Agent Requirements

If you manufacture food, drugs, medical devices, cosmetics, or dietary supplements outside the United States and you want access to the U.S. market, FDA registration is not optional — it is a legal prerequisite. And buried inside that registration requirement is a rule that catches many foreign manufacturers off guard: you must designate a U.S. Agent before your registration is accepted.

This guide covers everything a foreign manufacturer needs to know — who must register, what a U.S. Agent is legally required to do, how to complete the registration process, and what happens when you get it wrong.

Who Must Register with the FDA?

The registration obligation depends on your product category. Here is a breakdown of the primary regulatory frameworks:

Food Facilities — Under 21 CFR Part 1, Subpart H (Food Safety Modernization Act, Section 415), any foreign facility that manufactures, processes, packs, or holds food for U.S. consumption must register with FDA every two years during the October–December window in even-numbered years.
Drug Establishments — Under 21 CFR Part 207, foreign drug manufacturers, repackagers, and relabelers must register annually and list their products.
Medical Device Manufacturers — Under 21 CFR Part 807, foreign device manufacturers must register their establishments and list every device intended for U.S. distribution.
Cosmetic Facilities — Under the Modernization of Cosmetics Regulation Act of 2022 (MoCRA), foreign cosmetic facilities must register with FDA by December 29, 2023 (for facilities already in operation), with ongoing biennial renewals required.
Dietary Supplement Manufacturers — Foreign facilities manufacturing dietary supplements are treated as food facilities under 21 CFR Part 1 and face the same FSMA registration requirements.

Citation hook: Every foreign manufacturer that ships FDA-regulated products to the United States must designate a U.S. Agent as a condition of registration — without exception, regardless of product volume or shipment frequency.

What Is a U.S. Agent? Legal Definition and Role

The U.S. Agent is not a distributor, importer of record, or customs broker — though the same entity can serve multiple functions. Legally, a U.S. Agent is an individual or firm physically located in the United States who agrees to serve as the official point of contact between the foreign establishment and the FDA.

This requirement exists because FDA needs a reliable domestic contact for inspections, communications, and enforcement actions. A foreign address is not sufficient.

U.S. Agent Eligibility Requirements

To qualify as a U.S. Agent under FDA regulations:

Must be a resident of or have a place of business in the United States
Must be physically present in the U.S. (a post office box does not qualify)
Must be available during U.S. business hours to receive FDA communications
Must be authorized by the foreign establishment to act on its behalf
Cannot be a foreign national residing outside the U.S., even temporarily

What a U.S. Agent Is Legally Required to Do

Under 21 CFR 1.227(b)(13) for food facilities, and parallel provisions in other product regulations, the U.S. Agent must:

Receive inspection notifications — FDA will notify the U.S. Agent before conducting a foreign facility inspection. The agent must relay this information promptly.
Serve as FDA's communication conduit — All official FDA correspondence to the foreign establishment may be routed through the U.S. Agent.
Respond to FDA inquiries — The agent must be reachable and responsive. Failure to respond is treated as a failure by the foreign establishment.
Assist with registration updates — The U.S. Agent must be informed of any changes to facility registration information.
Facilitate emergency notifications (food facilities) — Under FSMA, the U.S. Agent may be contacted if FDA needs urgent access related to a food safety emergency.

Citation hook: Under 21 CFR 1.227(b)(13), a U.S. Agent for a foreign food facility must reside in or maintain a place of business in the United States and be available to serve as FDA's primary domestic point of contact for all official communications.

U.S. Agent vs. U.S. Importer: Key Differences

One of the most common misconceptions I encounter when working with foreign manufacturers at Certify Consulting is the assumption that their U.S. importer or distributor automatically satisfies the U.S. Agent requirement. That is not necessarily true.

Feature	U.S. Agent	U.S. Importer/Distributor
Primary Purpose	FDA compliance contact	Commercial transaction party
Physical U.S. Presence Required	Yes — mandatory	Yes, but for business reasons
Must Be Listed in FDA Registration	Yes	No (unless also named as agent)
Receives FDA Inspection Notices	Yes	No
Responds to FDA on Behalf of Foreign Facility	Yes	No
Can Be Same Entity as Distributor	Yes, if properly designated	Only if formally named as agent
Regulatory Basis	21 CFR 1.227, 807.40, 207.69	Varies by product type
Liability Exposure	High — direct FDA contact	Limited to import compliance

The importer can be named as the U.S. Agent — but this must be done explicitly, with the importer's written agreement, and the importer must understand they are accepting the regulatory obligations that come with it.

Step-by-Step: How Foreign Manufacturers Register with FDA

Step 1: Identify Your Product Category and Applicable Regulation

Before opening any FDA portal, confirm which regulations govern your product. A facility making both dietary supplements and cosmetics, for example, may need to register under multiple frameworks.

Step 2: Identify or Hire a Qualified U.S. Agent

This is the step most foreign manufacturers underestimate. You have three options:

Designate an employee or subsidiary with a U.S. address (must be a real location, not a virtual office)
Use your U.S. importer or distributor, with their explicit written consent
Hire a professional U.S. Agent service, which is the most reliable option for foreign facilities without a permanent U.S. presence

Professional U.S. Agent services typically cost between $300 and $2,500 per year depending on the product category and scope of services. This is not the place to cut corners — your entire U.S. market access depends on this designation.

Step 3: Gather Required Registration Information

Regardless of product type, you will generally need:

Full legal name and address of the foreign facility
Type of operations conducted at the facility
All product categories or specific products manufactured
U.S. Agent name, address, phone number, and email
Emergency contact information (food facilities)
Owner/operator name and contact information

Step 4: Submit Registration Through the Appropriate FDA System

Food Facilities — Use the FDA Food Facility Registration Module (FFRM) at the FDA Industry Systems portal
Drug Establishments — Submit through the FDA Electronic Drug Registration and Listing System (eDRLS)
Medical Devices — Use the FDA Unified Registration and Listing System (FURLS)
Cosmetic Facilities — Submit through the FDA Cosmetics Direct system (launched under MoCRA)

All systems require a DUNS number (or equivalent) and an FDA account. Allow 3–5 business days for processing in most cases, though device registrations that require 510(k) clearance have longer lead times.

Step 5: Confirm Registration and Obtain Your FDA Registration Number

Once submitted and accepted, FDA issues a registration number. For food facilities, this is a 10-digit number. For drug establishments, it is a 6-digit FEI (Firm Establishment Identifier). For devices, the FEI is also used.

Keep this number accessible — U.S. Customs will request it, and your importers will need it for entry documentation.

Step 6: Renew on Schedule

Registration is not a one-time event:

Food facilities: Biennial renewal, October–December of even-numbered years (2024, 2026, etc.)
Drug establishments: Annual renewal by December 31
Medical devices: Annual renewal by December 31
Cosmetic facilities: Biennial renewal

Consequences of Non-Compliance

The FDA does not treat registration failures lightly, particularly for foreign manufacturers.

Import Refusal at the Border

This is the most immediate and commercially devastating consequence. Under Section 801 of the Federal Food, Drug, and Cosmetic Act (FD&C Act), FDA has authority to refuse admission of any article from an unregistered foreign facility. Customs and Border Protection works directly with FDA's Operational and Administrative System for Import Support (OASIS) to flag shipments from non-compliant facilities.

In fiscal year 2023, FDA issued approximately 20,000 import alerts and refusals — a significant portion of which were linked to facility registration deficiencies.

Suspension of Food Facility Registration

Under FSMA Section 415(b), FDA can suspend the registration of a food facility — including a foreign facility — if it determines that food from that facility has a reasonable probability of causing serious adverse health consequences. A suspended registration means zero product can enter the U.S. market, full stop.

Warning Letters and Injunctive Action

For drug and device manufacturers, operating without registration (or with a lapsed registration) is a prohibited act under Section 301 of the FD&C Act. This can lead to Warning Letters, injunctions, and — in egregious cases — seizure of products already in U.S. commerce.

Criminal Liability

Section 303 of the FD&C Act provides for criminal penalties for violations of registration requirements. While criminal prosecution of foreign nationals is logistically complex, the U.S. Agent — who is physically present in the United States — faces full exposure.

Citation hook: FDA's authority to refuse admission of products from unregistered foreign facilities under Section 801 of the FD&C Act means that a single lapsed registration can halt an entire product line at the U.S. border without prior warning.

Special Situations: When Registration Gets Complicated

Contract Manufacturers and Co-Packers

If your product is manufactured at a third-party facility — even if you own the brand — the manufacturing facility itself must register. If that facility is outside the U.S., it needs its own U.S. Agent. The U.S. brand owner cannot substitute for the foreign facility's registration obligations.

Multiple Facilities Under One Owner

Each physical location must register separately. A corporation with five manufacturing plants in three countries needs five separate registrations, each with a designated U.S. Agent. One U.S. Agent can serve multiple facilities, but each registration must explicitly name that agent.

Changing Your U.S. Agent

If your U.S. Agent relationship ends — due to contract expiration, termination, or the agent ceasing operations — you must update your FDA registration immediately. Operating with an invalid or unresponsive U.S. Agent is treated the same as having no U.S. Agent.

The update must be made through the same FDA portal where you originally registered, and it takes effect upon submission (not upon FDA review).

Virtual Offices and P.O. Boxes

FDA has specifically addressed this issue: a P.O. box does not constitute a valid U.S. Agent address. A virtual office service — where no physical staff are reliably present — is similarly problematic. The regulation requires an address where the agent is genuinely reachable in person.

Choosing the Right U.S. Agent: What to Look For

Not all U.S. Agent services are equal. When evaluating options, consider:

Regulatory expertise: Does the service understand your product category's specific requirements? A food-focused agent may not be the right choice for a combination drug-device product.
Response protocols: What is their documented process for receiving and relaying FDA communications? What is their guaranteed response time?
Emergency availability: For food facilities, 24/7 availability for emergency contact is important.
Transparency: Will they give you copies of all FDA communications they receive on your behalf?
Track record: Ask for client references and verify they have no history of registration lapses for clients.

At Certify Consulting, we assist foreign manufacturers in identifying compliant U.S. Agent solutions and managing the full registration process across product categories.

With over 200 clients served and a 100% first-time audit pass rate across 8+ years, I've worked with foreign manufacturers from more than 30 countries navigating the FDA registration landscape. The mistakes I see most often are predictable and preventable:

Assuming a distributor relationship satisfies the U.S. Agent requirement
Using a virtual office or P.O. box as the agent address
Missing biennial renewal windows for food facilities
Failing to update the U.S. Agent after a business relationship changes
Registering only the parent company when multiple facilities are in operation

Frequently Asked Questions

Q: Can my U.S. customer or buyer serve as my U.S. Agent? A: Yes, but only with their explicit written consent and with the understanding that they are accepting regulatory obligations — including receiving FDA inspection notices and acting as FDA's official communication contact. Many buyers are unwilling to accept this liability, which is why professional U.S. Agent services are the most practical option for most foreign manufacturers.

Q: What happens if I ship products to the U.S. before completing FDA registration? A: Your shipment is subject to refusal at the border under Section 801 of the FD&C Act. Depending on the product and the circumstances, FDA may also issue an Import Alert, which places your facility on a watch list that can cause automatic detention of all future shipments until compliance is demonstrated.

Q: Is FDA registration the same as FDA approval? A: No. Registration is a listing requirement — it tells FDA that your facility exists and what you make. It does not mean FDA has reviewed or approved your products. Certain products (prescription drugs, many medical devices, most biologics) require separate premarket review and approval or clearance before they can be legally marketed in the U.S.

Q: Do I need a U.S. Agent if I only ship samples or small quantities? A: Yes. The registration and U.S. Agent requirement applies based on whether your facility manufactures, processes, packs, or holds regulated products for U.S. consumption — not based on shipment volume. There is no de minimis exemption for small quantities.

Q: How do I update my U.S. Agent information if my agent changes? A: Log into the applicable FDA portal (FFRM, eDRLS, FURLS, or Cosmetics Direct) and update the U.S. Agent information in your facility registration record. The change is effective upon submission. You do not need to wait for FDA confirmation, but you should retain a copy of the updated submission for your records.
