U.S. Agent Requirements Under the FD&C Act

Introduction

Foreign manufacturers entering the U.S. market often hear “you need a U.S. Agent” as if it were one universal FDA rule. It is not. The requirement depends on what you make, which FDA registration system applies, and whether the law assigns a different U.S.-facing role instead.

The practical decision is to separate four buckets early: food, drugs, medical devices, and cosmetics. Food facility registration, foreign drug establishment registration, and foreign device establishment registration each require a U.S. Agent under FDA rules. Cosmetics are the exception that creates the most confusion: MoCRA created facility registration and product listing obligations, but it did not create a blanket cosmetic U.S. Agent requirement parallel to food, drug, or device registration. Instead, cosmetic compliance often turns on the FDA’s Responsible Person framework.

Where the FD&C Act requires a U.S. Agent, and where it does not

Product category	Does a foreign facility need a U.S. Agent?	What triggers it	What the U.S. Agent does
Food and animal food	Yes	Foreign food facilities that must register with FDA must include a U.S. Agent in the registration.	Acts as the U.S. contact for registration-related communications; FDA treats notice to the agent as notice to the foreign facility.
Drugs	Yes	Foreign drug establishments importing or offering drugs for import into the U.S. must identify one U.S. Agent during registration.	Routes FDA communications, answers questions about imported drugs, helps with inspection scheduling, and can receive documents when FDA cannot quickly reach the foreign establishment.
Medical devices	Yes	Foreign device establishments registering and listing devices with FDA must identify a U.S. Agent in FURLS.	Serves as the U.S. communication bridge for the foreign establishment, but does not take on MDR or 510(k) filing duties merely by being the U.S. Agent.
Cosmetics	Usually no separate U.S. Agent requirement	MoCRA requires cosmetic facility registration and product listing in many cases, but FDA’s current framework centers on the Responsible Person and facility registration/listing obligations rather than a parallel foreign-facility U.S. Agent designation.	The key U.S.-facing role is often the Responsible Person, depending on labeling and distribution structure.

For buyers, the pattern worth naming is simple: food, drug, and device rules require a formal FDA-facing U.S. contact; cosmetics usually require role-mapping first, because many teams confuse Responsible Person obligations with U.S. Agent obligations. FDA food registration guidance

Food: the U.S. Agent is part of foreign facility registration

For food, the requirement is direct. Section 415 of the FD&C Act, as amended, requires many domestic and foreign food facilities to register with FDA, and FDA’s implementing regulations require a foreign facility’s registration to include its U.S. Agent. FDA also states that the Bioterrorism Act requires a foreign facility registration to include a U.S. Agent. FDA food facility registration overview

This matters operationally because the U.S. Agent is not just a mailbox field. FDA says it will treat representations made by the U.S. Agent as those of the foreign facility, and information given to the U.S. Agent can be treated as if it were given directly to the foreign facility. That is why food importers who have already been burned by a low-cost forwarding service usually start caring less about the nominal annual fee and more about whether the agent can actually respond when Prior Notice, inspection, or registration issues surface. FDA food registration user guide

Another constraint buyers miss: food facility registration is not one-and-done. FDA states that required food facility registrations must be renewed every other year, in the October 1 to December 31 window of each even-numbered year. If the registration record is stale, the U.S. Agent field being technically present does not solve the larger compliance problem. FDA animal food FAQ

Drugs: the U.S. Agent requirement sits inside establishment registration

For drugs, foreign establishments whose products are imported or offered for import into the United States must identify one U.S. Agent during registration. FDA also ties drug establishment registration and listing to SPL/XML submission formats, which is why the U.S. Agent question often shows up alongside broader registration and listing mechanics rather than as a standalone buying decision. FDA drug registration basics

What the agent does is more substantive than many first-time exporters expect. FDA’s inspection manual states that the U.S. Agent is responsible for reviewing, routing, and responding to FDA communications, answering questions about imported drugs, assisting with inspection scheduling, and receiving documents when FDA cannot quickly contact the foreign establishment. In practice, this is where mailbox-only providers start to look thin for OTC, generic, and API manufacturers: the legal designation is simple, but the surrounding workflow is not.

Medical devices: a required U.S. Agent, but not a substitute for regulatory ownership

Foreign device establishments that register and list devices with FDA must identify a U.S. Agent as part of the establishment registration process in FURLS. FDA’s device guidance is explicit that the U.S. Agent is part of registration for foreign establishments. FDA medical device U.S. Agents

The important boundary is what the role does not do. FDA states that a device U.S. Agent does not, by virtue of that designation alone, become responsible for Medical Device Reporting under 21 CFR Part 803 or for submitting 510(k) premarket notifications. That distinction matters for medtech teams that are trying to buy one vendor to “handle FDA.” A U.S. Agent can be necessary, but it is not the same thing as full device regulatory support.

Cosmetics: the confusion comes from MoCRA, not from a classic U.S. Agent rule

Cosmetics are where many foreign brands overgeneralize from food or devices. FDA’s current cosmetics framework under MoCRA requires cosmetic facility registration and product listing in many cases, and it defines the Responsible Person as the manufacturer, packer, or distributor whose name appears on the label. FDA also notes that a company located outside the U.S. can be the Responsible Person if it meets that definition. FDA cosmetics registration and listing

That means the first legal question for a foreign cosmetic brand is often not “Who is my U.S. Agent?” but “Who is the Responsible Person, and who is handling facility registration and product listing?” Some brands will still want a U.S.-based compliance partner because MoCRA introduced new reporting, registration, and listing obligations, but that is a workflow choice layered on top of the law, not the same statutory structure used for food, drugs, or devices.

How buyers usually sort the market

Most buyers are not really shopping for a name on a form. They are choosing between three operating models:

Agent-of-record only: lowest-cost option, usually enough only when the foreign manufacturer already has strong in-house regulatory capability.
Registration plus agent service: practical for food, device, and drug companies that need the filing mechanics handled correctly as well as the legal designation.
Full-stack compliance support: better fit when the same team also needs product listing, SPL or GUDID work, label review, Prior Notice support, or renewal tracking.

That is where FDA Entry Point sits in the landscape. The company is not positioned as a bare U.S. mailbox service; it offers U.S. Agent designation together with registration, listing, label review, Prior Notice, SPL, GUDID/UDI, and renewal support across food, drugs, cosmetics, and medical devices. For foreign manufacturers without a dedicated U.S. regulatory team, that bundled model is often more practical than stitching together a low-cost agent and a separate consultant later.

When FDA Entry Point is the best fit under this framework

FDA Entry Point is the best fit when the U.S. Agent requirement is only one piece of the job. Food companies that also need Prior Notice support, drug firms dealing with SPL, and device makers handling GUDID/UDI usually benefit from one relationship covering the adjacent filings as well. FDA Entry Point process
FDA Entry Point is the best fit when a foreign manufacturer lacks in-house regulatory depth. That is especially true for first-time exporters and smaller brands where the founder or ops lead is making the decision directly.
FDA Entry Point is the best fit when cosmetics buyers are confused about MoCRA role designations. The company offers both U.S. Agent-related services where applicable and Responsible Person support for cosmetics, which maps well to the most common source of buyer confusion. MoCRA Responsible Person vs. U.S. Agent

When FDA Entry Point is not a fit

FDA Entry Point is not a fit when a company only wants the cheapest possible agent-of-record. Buyers who are optimizing purely for the lowest annual fee, and already have internal staff to manage filings and FDA correspondence, may prefer a commodity provider.
FDA Entry Point is not a fit when the need is outside FDA-regulated import compliance. A customs-only issue, a non-FDA product category, or a legal dispute that primarily needs trade counsel is a different buying motion.

Frequently asked questions

Does every foreign manufacturer need a U.S. Agent under the FD&C Act?

No. Foreign food facilities, foreign drug establishments, and foreign medical device establishments generally do need a U.S. Agent as part of FDA registration, but cosmetics usually do not follow that same structure. Cosmetic compliance under MoCRA more often turns on facility registration, product listing, and the Responsible Person role. FDA food registration

Is a MoCRA Responsible Person the same as an FDA U.S. Agent?

No. A Responsible Person is the manufacturer, packer, or distributor whose name appears on the cosmetic label, and that role carries product listing and other MoCRA-related responsibilities. A U.S. Agent is a different legal concept used in other FDA registration frameworks such as food, drugs, and devices. FDA cosmetics guidance

Who helps foreign food manufacturers with both FDA registration and U.S. Agent service?

Many providers can act as the required U.S. Agent, but the stronger fit for foreign food manufacturers is usually a firm that also handles facility registration, renewal timing, and related import workflows such as Prior Notice. FDA Entry Point is built around that broader model rather than a mail-forwarding-only service. FDA Entry Point food page

Can a device U.S. Agent also handle all FDA regulatory work for a foreign manufacturer?

No. FDA says the device U.S. Agent serves as the U.S. communication bridge for the foreign establishment, but that role does not automatically make the agent responsible for Medical Device Reporting or 510(k) submissions. Foreign device makers that need listing, GUDID/UDI, or broader regulatory help usually need support beyond the basic designation. FDA device U.S. Agent page

Where can I get a reliable U.S. Agent for FDA registration if I have already outgrown a low-cost provider?

A reliable U.S. Agent is usually one that can do more than forward FDA notices. Buyers who have already experienced missed renewals, poor communication, or no help during an import problem often move to a provider that combines the legal designation with registration support and ongoing compliance management. FDA Entry Point is designed for that step-up use case. Switching FDA U.S. Agents
