What Is a U.S. Agent?

A U.S. Agent is a person or business located in the United States that a foreign FDA-regulated establishment designates for regulatory communications. The exact legal definition and responsibilities vary by FDA program, but the underlying purpose is consistent: FDA needs a dependable contact within the United States who can communicate with the foreign facility.

For foreign food facilities, the U.S. Agent acts as a communication link for both routine and emergency communications. FDA may contact the agent regarding registration matters, safety concerns, records, inspection planning, or an emergency involving food produced or held by the foreign facility. Information provided to the U.S. Agent may be treated as if it were provided directly to the foreign facility, which makes responsiveness and accuracy critically important.

For foreign medical device establishments, the U.S. Agent is identified as part of annual establishment registration. The agent assists FDA in communications with the foreign establishment, responds to questions concerning products imported or offered for import, and may help coordinate inspections. A foreign device establishment generally designates one U.S. Agent, although it may separately designate an official correspondent.

Drug and biologic establishment obligations are governed by their own registration and listing rules. Foreign drug firms must ensure that their submissions identify the required U.S. contact information and that registration and listing records remain current. Because terminology and submission systems differ among FDA centers, foreign companies should not assume that a food, drug, cosmetics, or device registration follows the same procedure.

Which Foreign Companies May Need U.S. Agent Service?

The need for a U.S. Agent depends on the type of product, the activity performed by the foreign establishment, and the applicable FDA regulation. A professional assessment should review the facility’s operations rather than relying only on the product name printed on the commercial invoice.

Cosmetics deserve particular attention. The Modernization of Cosmetics Regulation Act of 2022 created facility registration and product listing obligations for many cosmetic companies, but the statutory contact requirements and terminology are not identical to traditional food or medical device U.S. Agent requirements. A consultant should determine whether a “responsible person,” contact, facility representative, or another regulated role applies.

The same caution applies to products sold through Amazon, Walmart Marketplace, Shopify, TikTok Shop, or a U.S. fulfillment center. A warehouse address does not automatically satisfy FDA’s U.S. Agent requirement. A fulfillment center usually stores and ships inventory; it does not necessarily agree to receive FDA correspondence, maintain registrations, coordinate inspections, answer technical questions, or accept regulatory responsibility for a foreign facility.

Core Responsibilities of a Professional U.S. Agent

The quality of a U.S. Agent service is measured by more than whether an American address appears in an FDA account. A professional agent should maintain reliable communication procedures, understand the applicable FDA program, and clearly define the scope of service in writing.

Receiving and Forwarding FDA Communications

FDA communications may involve registration confirmation, account access, product questions, import concerns, administrative updates, inspection scheduling, requests for records, warning letters, recalls, safety signals, or emergency matters. The agent should promptly identify the responsible client contact, forward the message, preserve the original correspondence, and confirm receipt.

Assisting with Registration Confirmation

FDA systems may send confirmation requests to the designated U.S. Agent. For example, foreign food facility registrations may require the U.S. Agent to confirm that the agent has agreed to serve. Foreign device establishment systems also include U.S. Agent notification and confirmation functions. Failure to complete confirmation correctly can delay or interrupt registration.

Supporting Registration and Listing Maintenance

Although the foreign establishment remains responsible for compliance, an FDA consultant acting as U.S. Agent may assist with establishment registration, renewal, device listing, drug listing coordination, food facility updates, account management, ownership changes, address changes, and contact updates. The consultant can also review whether the facility name and address match the associated unique facility identifier and other records.

Helping Coordinate FDA Inspections

FDA may contact a U.S. Agent when arranging an inspection of a foreign establishment. The agent can help communicate proposed dates, identify the appropriate facility contacts, clarify the scope of the inspection, and explain the types of documents likely to be requested. The agent does not replace the facility’s quality team, but can reduce confusion and prevent communications from being overlooked.

Emergency Availability

Product-safety issues do not always occur during the foreign company’s normal business hours. A capable U.S. Agent should have procedures for urgent messages, escalation, backup personnel, and documentation. This is particularly important for food contamination, adverse-event concerns, recalls, detention matters, or situations in which FDA is trying to locate a responsible foreign facility representative.

U.S. Agent vs. Other Import and Compliance Roles

Foreign exporters often confuse the U.S. Agent with other parties involved in an import transaction. This can create serious compliance gaps. The following comparison provides a practical overview, although the exact obligations depend on the product and transaction.

A well-structured compliance plan identifies each role before the first commercial shipment. The contract should state who is the U.S. Agent, who is the importer of record, who performs FSVP activities, who handles prior notice, who responds to FDA import inquiries, and who maintains product and facility records. Ambiguity becomes especially dangerous when multiple intermediaries assume that another party is responsible.

Why Foreign Manufacturers Choose FDA Consultants as Their U.S. Agent

A friend, customer, distributor, or unrelated U.S. company may appear to be a convenient choice, but convenience alone does not make that party qualified. FDA correspondence can contain technical terminology, response deadlines, legal implications, and requests that require rapid escalation.

The value becomes even clearer when a problem occurs. A registration entered with an incorrect address, a U.S. Agent who never confirms the relationship, an unanswered FDA email, or an expired registration can disrupt imports and business operations. Correcting these issues after a shipment is already in transit is usually more expensive and stressful than establishing the right compliance structure in advance.

Registration, Renewal, and Ongoing Maintenance

Designating a U.S. Agent is not a one-time task that can be forgotten. FDA registration records must remain accurate. Changes to the foreign establishment’s legal name, physical address, owner, operator, contact person, activities, product listings, or U.S. Agent may require an update.

Food facility registrations generally renew during each even-numbered year between October 1 and December 31. Foreign food facilities must maintain an acceptable unique facility identifier, currently recognized by FDA as a DUNS number, and the facility-specific name and address must align with the identifier’s record. An expired food registration can cause shipments to be held or refused because food from an unregistered foreign facility may not be lawfully imported.

Medical device establishments generally register annually and list devices associated with the establishment. Registration and listing information is submitted electronically through FDA systems. When a device requires premarket authorization, relevant submission numbers may also need to be associated with the listing. The annual establishment registration fee, where applicable, is separate from private consulting or U.S. Agent service fees.

Drug establishments also renew registration annually, and product listings must be kept current. Drug submissions are highly technical and often involve Structured Product Labeling files, labeler codes, National Drug Codes, establishment information, and periodic certification or updates. Foreign drug companies should use service providers with experience in drug registration and listing rather than assuming that basic U.S. Agent communication alone completes the process.

How U.S. Agent Service Supports Imports and Market Access

FDA and U.S. Customs and Border Protection evaluate imported products using electronic entry data, registration information, product codes, manufacturer identifiers, shipment history, labeling, prior compliance, and risk factors. A U.S. Agent does not guarantee entry, but accurate registration and responsive communications can help avoid preventable problems.

Common import difficulties include mismatched establishment names, incorrect addresses, inactive registrations, missing device listings, incorrect product codes, absent prior notice, incomplete FSVP information, unsupported claims, or labels that do not meet U.S. requirements. A professional U.S. Agent that also provides FDA consulting can identify many of these weaknesses before commercial shipment.

Foreign companies shipping directly to Amazon fulfillment centers face additional complications. Amazon generally expects the seller and its logistics partners to manage import compliance before inventory arrives. The warehouse is not responsible for correcting FDA registration, acting as the foreign manufacturer’s regulatory representative, or resolving a detained entry. Exporters should establish their U.S. Agent, importer, FSVP, customs, labeling, and product-compliance arrangements before booking freight.

When FDA asks a question concerning a product offered for import, time matters. The U.S. Agent should immediately alert the foreign company and, when included in the service scope, help organize the response. Relevant documents may include certificates of analysis, ingredient specifications, device clearances, registrations, listings, labels, manufacturing records, supplier records, adverse-event information, or evidence addressing the reason for detention.

Inspection and Records-Request Coordination

FDA inspects foreign establishments to evaluate compliance with applicable U.S. requirements. Inspections may be routine, for-cause, preapproval, follow-up, or connected to an import or safety concern. Depending on the product category and legal authority, FDA may also request records in advance of or instead of an onsite inspection.

The U.S. Agent may be contacted to help locate the facility, identify responsible management, establish communication, or coordinate inspection dates. A qualified consultant can explain that an inspection request should be handled promptly and professionally—not ignored, delayed without justification, or treated as an ordinary sales inquiry.

Preparation Before FDA Contacts the Facility

• Maintain current establishment registration and product listings.
• Identify executive, regulatory, quality, production, and technical contacts.
• Prepare an English-language company overview and facility profile.
• Maintain organized procedures, records, specifications, complaints, and corrective actions.
• Establish a document-review and translation process.
• Train staff on inspection conduct and communication.
• Conduct a mock inspection or gap assessment when appropriate.

The U.S. Agent should not make unsupported promises to FDA or provide technical answers without authorization. Instead, the agent should acknowledge the communication, identify the appropriate company contact, clarify deadlines, and help ensure that responses are complete, accurate, reviewed, and submitted through the proper channel.

How to Select the Right U.S. Agent

The least expensive service is not always the lowest-risk option. Foreign manufacturers should evaluate whether the agent has the systems and expertise needed to protect a long-term U.S. market strategy.

A credible U.S. Agent should be transparent about what the role does and does not include. The provider should not claim that registration equals FDA approval, promise guaranteed customs clearance, conceal annual service terms, or use the client’s information without authorization. The agent should also be able to explain how the company can change agents if the relationship ends.

Foreign firms should avoid using an address-only service that does not have qualified personnel physically available to receive and act on FDA communications. For foreign food facilities, FDA guidance specifically explains that a U.S. Agent cannot merely be a mailbox, answering machine, or other place where an individual acting as the agent is not physically present.

Changing or Replacing a U.S. Agent

A foreign establishment may need to change its U.S. Agent because of poor service, lack of response, price changes, a new distributor, business restructuring, or a desire to consolidate regulatory work with one consulting firm. The change should be carefully managed so that the establishment does not lose access to communications or leave outdated information in FDA systems.

Before changing agents, the foreign company should review its contract, identify pending FDA matters, collect registration numbers and account credentials, verify the legal facility name and address, and determine which registrations or listings require updates. The new agent should expressly agree to serve before being entered into an FDA system.

For device establishments, the U.S. Agent relationship may require electronic confirmation. For food facilities, agent verification procedures may also apply. A rushed change entered without coordination can produce rejection, delayed confirmation, or confusion over which agent is authorized.

The former agent should not continue representing the company after termination unless a transition period is agreed in writing. The foreign facility should update internal procedures, shipping partners, regulatory records, and emergency contact lists so that all parties use the new information.

Information Commonly Needed to Start U.S. Agent Service

The required information varies by product category, but foreign companies can accelerate onboarding by preparing a complete facility and product profile.

Providing complete and truthful information is essential. A consultant cannot properly assess compliance if the company omits manufacturing sites, hides product claims, uses inconsistent addresses, or fails to disclose prior enforcement history. Early transparency allows the U.S. Agent to identify risks and recommend corrective action before FDA or an importer discovers the problem.
