What Is a US FDA Agent — And Why Every Foreign Food Facility Must Have One

A US FDA Agent for foreign facilities is one of the most misunderstood requirements in FDA food compliance. Every foreign food facility registered with the FDA must designate a US Agent — a physical or legal person residing in the United States who acts as the facility's point of contact with the agency. The requirement comes directly from the Bioterrorism Act of 2002, and it applies to every foreign facility that manufactures, processes, packs, or holds food intended for US consumption. No US Agent means no valid registration, and no valid registration means shipments cannot clear customs.

What a US FDA Agent actually does

The US Agent is not a consultant, distributor, or importer. Under 21 CFR 1.227, the US Agent is the legal representative of the foreign facility for all FDA communications relating to that facility. The agent must have a physical address in the United States (a P.O. box does not qualify), must be available during normal business hours, and must respond to FDA communications on behalf of the facility — whether those communications concern registration updates, import alerts, inspection notices, or enforcement actions.

When the FDA needs to reach a foreign facility quickly — for example, during an import refusal at a US port or when issuing a subpoena — the agency does not attempt to contact the factory directly. It contacts the US Agent, who is legally obligated to pass the communication on and coordinate the response. If the US Agent is unreachable or unresponsive, the facility's registration can be flagged, suspended, or invalidated, and any shipments in transit will be held at the border.

Why the US Agent requirement exists

Before the Bioterrorism Act, the FDA had limited ability to enforce compliance against foreign manufacturers. A facility in another country could be linked to a contamination event, adulteration issue, or misbranding violation, and the agency had no legal mechanism to compel a response. Assigning a US-based legal representative closed that gap. The US Agent creates an accountable party on American soil — someone the FDA can serve with legal notices, someone who must answer questions during import review, and someone who can coordinate corrective action when problems arise.

For food specifically, the US Agent also plays a role in the Prior Notice system for inbound shipments and in the Foreign Supplier Verification Program (FSVP) communications. The agent is often the first party contacted when a shipment is flagged at the border for documentation issues, labeling problems, or inspection holds. Without a responsive US Agent in place, those holds can escalate into full refusals within hours.

Who can serve as a US FDA Agent for foreign facilities

The US Agent must be a US resident or a US-based legal entity with a physical address in any of the 50 states, the District of Columbia, or a US territory. It cannot be the FDA itself, cannot be a mail forwarding service, and cannot be an overseas office claiming a US mailing address. The agent must be able to receive and respond to FDA communications in English during US business hours, and must be explicitly designated in the facility's FDA registration record.

In practice, most foreign facilities use a professional US Agent service rather than appointing a distributor or importer. The reason is accountability. A distributor's relationship with the foreign facility can end — contracts expire, partnerships dissolve, markets change. If a distributor is acting as the US Agent and the relationship ends, the facility's FDA registration can be left without a valid agent, sometimes without the facility knowing. A professional US Agent service is structured to be durable across commercial changes and to maintain continuous coverage regardless of distribution arrangements.

Common US FDA Agent mistakes foreign facilities make

The most common mistake is assuming that an importer or distributor is automatically the US Agent. They are not. The US Agent must be explicitly designated in the FDA registration with full contact details — name, US address, phone number, and email. Many foreign facilities discover years later that their registration lists no US Agent or lists a former distributor who no longer represents them. That registration is functionally invalid, even though the system shows it as active.

Another common mistake is appointing a US Agent without a formal agreement in place. The US Agent has real legal exposure — they can be served with FDA legal notices, subpoenas, and administrative actions on behalf of the facility. Without a written agreement defining the scope of authority, response obligations, and liability boundaries, both the facility and the agent are operating in a gray zone. A proper US Agent appointment includes a written service agreement, not just a name and address in the FDA system.

How the US Agent role differs from the EU Responsible Person

Brands that sell into both the US and EU markets often conflate the US Agent with the EU Responsible Person. The two roles are not equivalent. The EU Responsible Person under Regulation 1223/2009 has substantive legal obligations — holding the Product Information File, ensuring safety assessments are current, reporting serious undesirable effects, and taking corrective action for non-compliant products. The US Agent's role is narrower: it is primarily a communication and legal service function, not a product safety accountability function.

The practical consequence is that a single entity cannot automatically serve both roles across both jurisdictions. A US Agent service provider in New Jersey cannot act as an EU Responsible Person in Frankfurt. Foreign brands selling into both markets need separate appointments in each jurisdiction, with separate agreements, separate fees, and separate compliance obligations. Treating them as interchangeable is a common cause of compliance gaps.
