US Agent Requirements for Foreign Establishments

Understand when you need a US Agent, what responsibilities they have, qualification requirements, and how to select the right agent for your FDA-regulated business.

Quick Answer

A US Agent is required for all foreign establishments that export FDA-regulated products to the United States, including food, drugs, medical devices, cosmetics, and tobacco products. The US Agent must be a person or business located in the US who serves as the communication link between the foreign facility and FDA, available 24/7 for emergency contact.

Regulatory Authority: 21 CFR 1.227 (food), 21 CFR 207.69 (drugs), 21 CFR 807.40 (devices)

An FDA US Agent is a person or company located in the United States that is required by federal regulation for any foreign establishment exporting FDA-regulated products (food, drugs, devices, cosmetics, tobacco) to the US. The US Agent serves as the official communication link between the foreign facility and FDA under 21 CFR 1.227 (food), 21 CFR 207.69 (drugs), and 21 CFR 807.40 (devices). For official FDA guidance on registration requirements, see the FDA food facility registration portal and the FDA device registration page.

The US Agent requirement exists because FDA needs a reliable way to contact foreign facilities, especially during emergencies such as product recalls, disease outbreaks, or safety concerns. Time zone differences and communication barriers can make direct contact with foreign facilities challenging.

Foreign Facility

Any facility located outside the United States that manufactures, processes, packs, or holds FDA-regulated products for export to the US

US Agent

A person or business physically located in the United States who represents the foreign facility in FDA matters

Communication Link

Receives and responds to FDA communications, forwards information to the foreign facility, and assists with regulatory matters

Compliance Partner

Many US Agents also provide compliance support, helping foreign facilities navigate FDA requirements

A US Agent has specific responsibilities defined by FDA regulations. Understanding these responsibilities is crucial both for foreign facilities selecting an agent and for entities considering becoming a US Agent.

Core Responsibilities

  • Receive communications from FDA: Accept all FDA correspondence, including warning letters, recall notices, and inspection requests
  • Respond to FDA inquiries: Provide timely responses to FDA questions and requests for information
  • Forward communications: Promptly transmit FDA communications to the foreign facility
  • Assist with regulatory processes: Help coordinate inspections, registrations, and other regulatory matters

Availability Requirements

The US Agent must be available to FDA. While regulations don't explicitly require 24/7 availability, FDA expects to be able to reach the US Agent during normal business hours and receive a response within a reasonable timeframe. In emergency situations, FDA may need to contact the US Agent outside normal hours.

Important Limitation

A US Agent cannot refuse to accept service of a regulatory action. When FDA delivers a warning letter, import alert, or other action to the US Agent, it is considered delivered to the foreign facility. The foreign facility cannot claim they didn't receive notice.

It's important to understand the distinction between a US Agent and other roles in the import/distribution chain:

RolePrimary FunctionLocationRequired?
US AgentFDA communication linkMust be in USYes, for foreign facilities
Importer of RecordCustoms entry and dutiesUsually in USYes, for imports
FSVP ImporterFood safety verificationMust be in USYes, for food imports
US DistributorProduct distributionUsually in USCommercial need

While these roles can be performed by the same entity, they have different regulatory requirements and responsibilities. A US Agent does not automatically become the importer or assume FSVP responsibilities.

How Do I Choose the Right US Agent?

Selecting the right US Agent is an important decision for foreign facilities. Consider these options and factors:

Options for US Agent

  • Attorney or consultant: A US-based regulatory professional can serve as US Agent

Factors to Consider

  • Expertise: Does the agent understand FDA regulations for your product type?
  • Availability: Will they be available when FDA calls?
  • Communication: Can they effectively communicate with you across time zones?
  • Additional services: Do they offer compliance support, registration assistance, or other services?
  • Reputation: What is their track record with other clients?
  • Cost: What are their fees and what services are included?

Why Professional US Agent Services?

While using an importer or distributor as your US Agent may seem convenient, professional US Agent services offer dedicated focus on FDA compliance, regulatory expertise, and consistent availability. If your business relationship with an importer ends, you'll need to quickly find a new US Agent and update your registration. Our US Agent Wizard can help you determine exactly what you need.

Frequently Asked Questions About US Agents

How much does a US Agent cost?

Assurentry charges $399/year for US Agent services. Market rates typically range from $250-$900/year depending on the provider and level of service. Some providers bundle US Agent services with registration assistance or compliance monitoring.

Can I be my own US Agent?

No, the US Agent must be a person or company based in the United States that is separate from the foreign facility. A foreign facility owner cannot serve as their own US Agent, even if they have a US mailing address. The agent must reside or maintain a place of business in the US per 21 CFR 1.227.

How quickly can I get a US Agent?

Assurentry provides same-day acceptance letters for US Agent designation. Once you complete the onboarding process, we issue an official acceptance letter that you can use to complete or update your FDA registration immediately.

What are the legal requirements for a US Agent?

A US Agent must reside or maintain a place of business in the United States and be available during business hours to receive and respond to FDA communications (21 CFR 1.227). They must have a physical US address and be reachable by phone and email.

Can one US Agent represent multiple facilities?

Yes, a single US Agent can represent an unlimited number of foreign facilities. Professional US Agent services like Assurentry typically represent hundreds or thousands of foreign facilities across food, drug, device, and cosmetics categories.

What happens if my US Agent becomes unavailable?

If your US Agent becomes unavailable, you must update your FDA registration immediately with a new agent. A gap in US Agent coverage means FDA cannot contact your facility, which risks enforcement action including registration cancellation and import refusal.

Is the US Agent liable for the foreign facility's products?

No, the US Agent is not generally liable for product safety or compliance. Their role is to serve as a communication link between FDA and the foreign facility per 21 CFR 1.227. However, they can be liable for their own actions or misrepresentations to FDA.

Does the US Agent need to be registered with FDA?

No, the US Agent does not need separate registration with FDA. They are identified through the foreign facility's registration. There is no separate FDA registration requirement or fee for US Agents.

What happens if we don't have a US Agent?

Foreign facilities cannot complete FDA registration without designating a US Agent. Products from unregistered facilities can be refused entry at US ports under 21 CFR Part 1, Subpart H (food), 21 CFR 207.69 (drugs), or 21 CFR 807.40 (devices).

Can an individual be a US Agent?

Yes, an individual (not just a company) can serve as US Agent, as long as they reside or maintain a place of business in the United States and can fulfill the communication responsibilities defined in the applicable regulations.
