Why Medical Device Establishments Need a U.S. Agent for FDA Compliance

It Is a Legal Requirement Under 21 CFR 807.40

The obligation to designate a U.S. Agent is established in federal regulation. It is not an optional FDA recommendation and is not limited to companies that have received a warning letter, import detention, or inspection notice. The requirement applies when a foreign establishment is subject to medical device establishment registration and is involved with devices imported or offered for import into the United States.

Section 807.40 addresses establishment registration and device listing for foreign establishments. It requires covered foreign establishments to submit registration and listing information and to identify a U.S. Agent. Each foreign establishment may designate only one U.S. Agent, although the same U.S. Agent may represent multiple foreign establishments. The establishment may also designate the agent as its official correspondent, but these are distinct concepts and the additional official-correspondent designation is not mandatory.

The legal trigger is the regulated activity performed at the establishment—not the size of the company, the number of employees, the value of a shipment, the number of shipments per year, or the classification of the device alone. A small foreign manufacturer exporting a limited quantity of a Class I device may still need to register and appoint a U.S. Agent. Likewise, a contract manufacturer that does not own the brand may have separate registration obligations based on the activities it performs.

A U.S. Agent Is Required for Foreign Establishment Registration

FDA establishment registration identifies where regulated medical device activities are conducted. Device listing identifies the devices associated with a registered establishment. For foreign facilities, U.S. Agent information is submitted electronically through FDA’s device registration and listing system as part of the establishment registration process.

A foreign establishment cannot simply omit the agent and complete a valid registration as though it were a domestic establishment. FDA requires the name, address, telephone information, and email address of the designated U.S. Agent. The agency’s current electronic process also includes confirmation of the designation. When an establishment submits or updates U.S. Agent information, FDA sends a communication to the agent. The agent must confirm the relationship within the specified period, or the confirmation code may expire and the agent information may be removed from the registration.

Registration must also be maintained. Medical device establishments generally verify and renew registration annually during FDA’s annual registration period, and relevant information must be kept current. Changes to U.S. Agent contact information must be reported promptly in accordance with the regulation. A registration that contains an inactive email address, outdated telephone number, or unresponsive agent can create delays when FDA attempts to communicate with the facility.

Premarket authorization and establishment registration are separate requirements. A device may be 510(k)-cleared, authorized through De Novo, approved through PMA, or exempt from premarket notification, yet the foreign establishment may still need registration, listing, and a U.S. Agent before commercially distributing the device in the United States. Conversely, registration does not make an otherwise unauthorized device legally marketable.

The U.S. Agent Serves as FDA’s Official Communication Bridge

FDA regulates foreign establishments from a distance, often across multiple languages, time zones, and business cultures. The U.S. Agent provides a dependable domestic communication point. The regulatory responsibilities include assisting FDA in communications with the foreign establishment and responding to questions concerning devices manufactured, prepared, propagated, compounded, or processed by the establishment and imported or offered for import into the United States.

This communication function can become critical when FDA needs a timely answer. Questions may concern establishment identity, registration information, device listings, product status, manufacturing activities, an import entry, an inspection, or another compliance matter. The U.S. Agent may receive the inquiry directly or may be asked to help reach the foreign establishment and route the communication to the appropriate technical or management personnel.

A capable agent should have reliable intake procedures, current client contacts, clear escalation channels, and sufficient familiarity with medical device terminology to recognize urgent matters. Simply forwarding every email without context may be technically possible, but it can be operationally inadequate when a message requires rapid attention. An experienced provider can identify deadlines, request missing facts, explain the purpose of the communication, and help the manufacturer organize a coordinated response—while preserving the manufacturer’s responsibility for the substance and accuracy of that response.

The agent’s role is particularly valuable when the foreign company’s normal business hours do not overlap with FDA’s working hours. A domestic contact can acknowledge receipt, prevent messages from remaining unnoticed, and help ensure that responsible personnel are mobilized before a deadline is missed.

Who Must Appoint a Medical Device U.S. Agent?

The answer depends on the activities performed by the foreign establishment. FDA’s registration requirements cover several establishment types. A company should evaluate its actual operational role rather than relying only on commercial labels such as “supplier,” “brand owner,” or “exporter.” More than one foreign establishment in a supply chain may need its own registration and its own U.S. Agent.

Device classification does not eliminate the requirement when the establishment itself is required to register. Class I, Class II, and Class III establishments may all be affected. Some device types or establishment activities may qualify for exemptions from particular requirements, but exemptions should be confirmed carefully rather than assumed.

The U.S. Agent Assists FDA in Scheduling Foreign Inspections

Foreign medical device establishments are subject to FDA inspection. The U.S. Agent’s expressly stated responsibilities include assisting FDA in scheduling inspections of the foreign establishment. This makes accurate contact information and prompt cooperation especially important.

Inspection scheduling can involve identifying suitable dates, confirming the physical site, identifying responsible contacts, clarifying the establishment’s activities, and facilitating communications between FDA and the foreign facility. The U.S. Agent does not replace the company’s management representative, quality unit, technical personnel, or legal counsel. Nor does the agent conduct the FDA inspection. The agent helps establish and maintain the communication channel needed to arrange the inspection.

Foreign establishments should prepare before an inspection notice arrives. They should maintain an inspection-readiness procedure, identify the personnel authorized to communicate with FDA, confirm the availability of interpreters where needed, and ensure that records can be produced in a usable form. Quality system documents, complaint files, Medical Device Reporting procedures, design records when applicable, production and process controls, corrective and preventive action records, supplier controls, labeling controls, and distribution records may all become relevant depending on the inspection scope.

An experienced U.S. Agent can support readiness by maintaining current establishment contacts and helping the company understand the scheduling process. Separate consulting services may also be available for mock inspections, document review, response planning, or remediation, but those activities go beyond the minimum regulatory functions of a U.S. Agent and should be defined clearly in the service agreement.

Consequences of Failing to Designate or Maintain a U.S. Agent

Failure to provide a valid U.S. Agent can prevent a foreign establishment from completing or maintaining FDA registration. Because devices generally may not be imported or offered for import unless applicable registration and listing requirements are satisfied, an invalid registration can create a serious market-access problem.

At the border, FDA reviews electronic import data and may examine whether the foreign manufacturer is properly registered, whether the device is listed, whether required premarket authorization exists, and whether other applicable requirements appear to be met. An unresolved establishment or listing issue may contribute to entry delays, requests for information, detention, or refusal. The facts of each entry matter, and having a U.S. Agent does not guarantee admission. Nevertheless, lacking a required agent or valid registration removes a basic compliance element needed for lawful commercial distribution.

Operational consequences can extend beyond a single shipment. An importer, distributor, marketplace, healthcare customer, or business partner may request evidence that the foreign establishment is registered and its devices are properly listed. Problems with the registration can interrupt purchase orders, delay onboarding, undermine due diligence, or cause a distributor to suspend commercial activity.

A company may also lose valuable time if its designated agent becomes unreachable, declines the designation, or fails to confirm the relationship. Foreign establishments should therefore treat the U.S. Agent appointment as a continuing compliance function rather than a one-time data-entry task.

Key Regulatory and Practical Requirements for the U.S. Agent

The U.S. Agent must reside or maintain a place of business in the United States. A mailbox, answering service, or similar arrangement that does not provide an actual U.S. presence is not an adequate substitute. The agent should be available to answer the telephone or otherwise maintain an employee available during normal business hours.

Each foreign establishment may designate only one U.S. Agent. This does not prevent a manufacturer from retaining other consultants, attorneys, import specialists, submission specialists, or distributors. It means that only one person or entity is identified in FDA’s registration system as the establishment’s U.S. Agent at a given time.

The foreign establishment should provide accurate contact details and should keep the relationship current. A useful written agreement normally defines the represented legal entity and site, the covered registration period, communication procedures, emergency contacts, language support, renewal terms, fees, confidentiality, document-handling expectations, and termination procedures.

• Physical residence or place of business in the United States
• Reliable availability during normal business hours
• Accurate telephone and email contact information
• Formal designation for the specific foreign establishment
• Prompt routing of FDA communications and deadlines
• Ability to assist with questions and inspection scheduling
• Clear escalation procedures for urgent regulatory matters
• Timely updates when agent information changes

Why Choosing the Right U.S. Agent Matters

Although the regulation defines a limited core role, the quality of the provider can have a substantial practical impact. A responsive agent can help ensure that communications reach the correct people quickly. An inattentive agent may allow a critical email to remain unanswered, send correspondence to the wrong contact, or fail to recognize the urgency of an inspection-related request.

Foreign establishments often consider appointing a distributor or importer as their agent. That arrangement may be legally possible when the party meets the requirements and agrees to serve, but companies should evaluate conflicts of interest and continuity risks. A distributor may prioritize its own commercial interests, may represent competing products, or may cease doing business with the manufacturer. If the relationship ends abruptly, control of an important regulatory communication channel may become complicated.

An independent U.S. Agent can provide greater continuity and neutrality. The agent’s role can remain stable even when distributors, logistics providers, or marketplace strategies change. Independence may also reduce the risk that commercial disagreements interfere with FDA communications.

Experience with medical devices is particularly valuable. Device regulation has terminology and processes that differ from food, cosmetics, drugs, and other FDA-regulated categories. The provider should understand establishment types, device listing, premarket pathways, inspection communications, import issues, and the distinction between a U.S. Agent, an official correspondent, an initial importer, an importer of record, and a regulatory consultant.

Questions to Ask Before Appointment

• Does the provider have a real physical place of business in the United States?
• How quickly are FDA communications acknowledged and forwarded?
• Is there a defined procedure for urgent inspection or import-related matters?
• Does the provider understand medical device establishment registration and listing?
• Can the provider communicate effectively with the foreign establishment’s team?
• What happens if the primary contact is unavailable?
• Are renewal dates, fees, additional consulting services, and termination terms clearly documented?
• Will the provider assist with registration updates and agent confirmation when authorized?

U.S. Agent Versus Other Medical Device Roles

Foreign manufacturers sometimes use several U.S.-based parties, and their roles should not be confused. A U.S. Agent is the FDA communication contact identified by the foreign establishment. An official correspondent may manage registration and listing communications on behalf of an owner or operator. An initial importer is generally the U.S. entity that furthers the marketing of a device from a foreign manufacturer to the person making final delivery or sale to the ultimate consumer or user, without repackaging or otherwise changing the device container, wrapper, or labeling. An importer of record is a customs role associated with entry obligations. A 510(k) or regulatory consultant may prepare submissions and provide strategic advice.

One entity may perform more than one role, but the legal duties do not merge merely because the same company is named. For example, designating an initial importer as U.S. Agent does not eliminate the importer’s own regulatory duties, and retaining a U.S. Agent does not satisfy customs entry responsibilities. Clear contracts and accurate FDA records help prevent confusion about who is responsible for each function.

Practical Steps for Appointing and Maintaining a U.S. Agent

1. Classify the establishment’s activities. Determine whether the site is a manufacturer, specification developer, contract manufacturer, sterilizer, repackager, relabeler, remanufacturer, or another regulated establishment type.
2. Confirm the device’s regulatory pathway. Identify classification, product code, listing requirements, and any applicable 510(k), De Novo, PMA, exemption, or other premarket status.
3. Select a qualified U.S. Agent. Verify physical U.S. presence, availability, medical device experience, communication procedures, and independence.
4. Execute a written service agreement. Clearly identify the establishment, scope, contacts, fees, renewal, confidentiality, and procedures for FDA communications.
5. Enter accurate information in FDA’s system. Submit the U.S. Agent’s correct name, address, phone number, and email address during initial registration or an authorized update.
6. Complete agent confirmation. Ensure that the U.S. Agent receives and timely confirms FDA’s notification when confirmation is required by the electronic system.
7. Maintain an internal response team. Identify regulatory, quality, technical, legal, and executive contacts who can respond when the agent forwards an FDA communication.
8. Renew and update annually. Verify registration, listing, importer information, and agent details during the annual registration cycle and update changes when required.
