Introduction: Why These Three Roles Are Commonly Confused

When a company outside the United States prepares to sell food, dietary supplements, cosmetics, medical devices, over-the-counter drugs, or other FDA-regulated products in the U.S. market, one of the first questions is: “Who must be listed in the United States?” The answer depends on the product category, the type of FDA requirement, the shipment structure, and the commercial relationship between the foreign manufacturer, U.S. buyer, customs broker, warehouse, marketplace, and distributor.

The confusion is especially common among Amazon sellers and direct-to-consumer brands. A foreign company may register a food facility with FDA and appoint a U.S. Agent. The same company may also need an FSVP Importer or FSVP Agent for food shipments. Separately, the customs broker may ask who will act as the Importer of Record for U.S. Customs and Border Protection. These are separate questions. Using one role incorrectly to cover another can lead to detained shipments, entry delays, FDA record requests, warning letters, customs penalties, marketplace holds, and commercial disputes.

For example, a Japanese food brand shipping shelf-stable snacks to an Amazon U.S. fulfillment center may have a registered foreign food facility and a U.S. Agent for FDA facility registration. That does not automatically solve the Foreign Supplier Verification Program requirement. FDA may still expect a properly identified FSVP Importer for each food line entry. The same shipment also requires a customs entry. CBP will expect an Importer of Record to use reasonable care in providing classification, value, origin, and other entry information. These functions can be performed by different parties, and in many cases they should be separated contractually.

This article provides a practical, business-focused explanation of U.S. Agent vs. FSVP Agent vs. Importer of Record. It is written for foreign manufacturers, exporters, Amazon FBA sellers, private-label brands, e-commerce operators, logistics companies, customs brokers, and U.S. buyers who need a clear compliance framework before products are shipped to the United States.

Chapter 1: The Core Difference in One Comparison Grid

The easiest way to understand the difference is to separate the agencies involved. The U.S. Agent is primarily an FDA registration communication role. The FSVP Agent relates to FDA food safety verification requirements under the Foreign Supplier Verification Program. The Importer of Record is a customs role tied to CBP entry obligations, duties, taxes, and reasonable care.

Chapter 2: What Is a U.S. Agent?

A U.S. Agent is a person or entity located in the United States that serves as a contact point between FDA and a foreign facility. In many FDA registration systems, foreign establishments must identify a U.S. Agent so FDA has a reliable domestic contact for communications, questions, emergency notifications, and regulatory coordination. This is especially familiar in the context of foreign food facility registration, medical device establishment registration, drug establishment registration, and other FDA-regulated categories where foreign facilities interact with FDA systems.

The U.S. Agent is not automatically the importer, buyer, distributor, customs filer, label reviewer, FSVP Importer, or party responsible for every FDA compliance requirement. The exact responsibilities depend on the product category and the service agreement between the foreign establishment and the U.S. Agent. At a minimum, the role is communication-based. FDA may contact the U.S. Agent when it cannot reach the foreign facility or when FDA needs a U.S.-based contact connected to the registered facility.

For foreign manufacturers, the U.S. Agent is often the first U.S. compliance contact established before exporting. The foreign facility may need the U.S. Agent’s information during FDA registration, renewal, or listing activities. However, appointing a U.S. Agent should not be treated as a complete compliance solution. The U.S. Agent does not automatically create a compliant FSVP file, review labels, prepare prior notice, pay customs duties, become the owner of the product, or assume liability for commercial sales unless those services are expressly included in a written agreement.

Common U.S. Agent tasks

• Support foreign facility registration and renewal communications.
• Receive FDA correspondence directed to the registered foreign facility.
• Help route urgent FDA communications to the correct company contact.
• Assist with updates to facility contact information where authorized.
• Coordinate with consultants, attorneys, brokers, laboratories, and regulatory teams when included in the service scope.

What a U.S. Agent is usually not

A U.S. Agent is not automatically the “responsible party” for all U.S. regulatory obligations. The U.S. Agent is not automatically the owner of the imported product. The U.S. Agent is not automatically the customs Importer of Record. The U.S. Agent is not automatically the U.S. distributor. The U.S. Agent is not automatically the party that guarantees product safety, labeling accuracy, tariff classification, or marketplace compliance. Those functions require separate review, documentation, and agreement.

Chapter 3: What Is an FSVP Agent?

The Foreign Supplier Verification Program, commonly called FSVP, applies to many imported foods for humans and animals. FDA explains that importers are required to develop, maintain, and follow an FSVP for each food brought into the United States and for each foreign supplier of that food. The purpose is to verify that foreign suppliers produce food in a manner that provides the same level of public health protection required under applicable U.S. food safety rules and that the food is not adulterated or misbranded with respect to allergen labeling.

Under the FSVP framework, the key question is: who is the FSVP Importer? In many transactions, the FSVP Importer is the U.S. owner or consignee of the food at the time of entry. When there is no U.S. owner or consignee, the foreign owner or consignee may designate a U.S. agent or representative as the FSVP Importer for the food. This is the role many businesses casually call an “FSVP Agent.”

The FSVP Agent role is much more compliance-intensive than a basic U.S. Agent role. FSVP involves supplier approval, hazard analysis, evaluation of supplier performance, verification activities, corrective actions, reevaluation, recordkeeping, and document readiness for FDA review. FDA can request FSVP records, and the records must be available promptly. Therefore, a company should not appoint an FSVP Agent casually or only as a name to place on entry documents. The role requires real compliance infrastructure.

Typical FSVP documentation

• Product-specific hazard analysis for biological, chemical, and physical hazards.
• Foreign supplier approval documentation.
• Supplier performance evaluation and compliance history review.
• Certificates of Analysis, testing records, audit reports, or other verification records.
• Corrective action records if hazards, supplier failures, labeling issues, or documentation gaps are identified.
• Reevaluation records and ongoing review of supplier status.
• Entry identification information, including FSVP importer name, email, and unique facility identifier when required.

Chapter 4: What Is an Importer of Record?

The Importer of Record, often abbreviated as IOR, is the party responsible for making or authorizing customs entry into the United States. This role is connected to U.S. Customs and Border Protection, not only FDA. The Importer of Record is responsible for using reasonable care when providing entry information, including tariff classification, customs value, country of origin, admissibility information, and other required data. The IOR may work through a licensed customs broker, but the broker’s involvement does not eliminate the importer’s responsibility.

For FDA-regulated products, the Importer of Record often works with a customs broker who transmits entry data to CBP and FDA through the import system. That entry may include FDA product codes, manufacturer information, shipper information, consignee information, prior notice for food, device listing data, drug listing data, or other admissibility details. If the data is wrong, incomplete, or inconsistent, the shipment may be delayed, examined, detained, refused, or flagged for further review.

The IOR role is commercial and legal. It may require a customs bond, importer identification number, power of attorney with a customs broker, recordkeeping procedures, and payment of duties, taxes, and fees. A foreign seller can sometimes act as a foreign Importer of Record if the broker and transaction structure allow it, but this requires careful planning. Some foreign sellers assume that a freight forwarder, Amazon warehouse, fulfillment center, or U.S. Agent automatically becomes the Importer of Record. That assumption can cause serious problems.

Common IOR responsibilities

• Authorize the customs broker through a valid power of attorney.
• Use reasonable care in declaring product classification, value, origin, and quantity.
• Pay duties, taxes, fees, and other import charges.
• Maintain import records and make them available when required.
• Coordinate admissibility data for FDA-regulated products.
• Respond to broker, CBP, FDA, and logistics questions related to the shipment.

Chapter 5: Can One Company Perform All Three Roles?

In some cases, one U.S. company may provide multiple services: U.S. Agent services, FSVP support, and Importer of Record coordination. However, the company should not be listed in all roles unless it has agreed in writing, understands the product category, has reviewed the compliance documents, and has the operational ability to perform the required responsibilities. The risk level is different for each role.

A U.S. Agent role may be limited to communication. An FSVP Agent role may require maintaining a full food safety verification file. An Importer of Record role may involve customs liability, duty exposure, bond obligations, and recordkeeping obligations. Combining them without clear contracts can create confusion when FDA, CBP, a broker, or a marketplace asks who is responsible for what.

For higher-risk foods, dietary supplements, infant products, seafood, acidified foods, low-acid canned foods, allergen-sensitive products, medical devices, OTC drugs, or cosmetics with drug-like claims, role separation and documentation become even more important. A professional provider may be willing to act as U.S. Agent but not as Importer of Record. Another provider may support FSVP records but not take title to goods. A customs broker may file entry but not serve as FSVP Importer. These limits are normal and should be respected.

Chapter 6: Product Category Matters

Not every FDA-regulated product uses the same structure. Food and dietary supplement shipments often raise FSVP questions. Medical devices may involve establishment registration, device listing, U.S. Agent, initial importer, and complaint handling. Cosmetics may involve MoCRA facility registration, product listing, responsible person information, adverse event records, safety substantiation, and labeling concerns. Drugs may involve establishment registration, drug listing, labeling, National Drug Code issues, and import admissibility review. The term “agent” can mean different things in each category.

For food, the FSVP requirement is one of the most important distinctions because it requires a risk-based verification program for each imported food and supplier combination unless an exemption applies. A food facility U.S. Agent is not the same as an FSVP Importer. A warehouse address is not automatically a compliant FSVP party. A customs broker is not automatically responsible for hazard analysis or supplier verification.

For medical devices, a foreign establishment may need a U.S. Agent for registration purposes, while a U.S. initial importer may have separate regulatory responsibilities. For cosmetics, businesses often confuse the U.S. Agent concept with the MoCRA responsible person concept, but these functions require separate analysis. For drugs, FDA registration and listing obligations are highly technical and should not be reduced to a simple “agent” appointment.

Before exporting, companies should identify the product category, intended use, claims, ingredients, labeling, packaging, manufacturer, exporter, U.S. destination, buyer, and sales channel. These facts determine which role is required and what documentation must be prepared before shipment.

Chapter 7: Why Marketplaces and Warehouses Create Extra Confusion

Amazon FBA, Walmart Marketplace, TikTok Shop, Shopify fulfillment partners, third-party logistics providers, and U.S. warehouses often receive imported products without becoming the legal party responsible for every import obligation. A fulfillment center may physically receive inventory, but physical receipt does not automatically equal FDA importer, FSVP Importer, Importer of Record, label guarantor, or product owner.

Many foreign sellers use delivery terms that create confusion. For example, a seller may ship DDP, meaning delivered duty paid, and assume that the logistics company has solved all U.S. compliance issues. In reality, DDP is a commercial shipping term. It does not replace FDA registration, FSVP, labeling review, prior notice, customs classification, or importer responsibility. A shipment can move through logistics channels and still fail FDA or CBP review if the regulatory data is incorrect.

Marketplace sellers should establish a compliance map before the first shipment. The map should identify the foreign manufacturer, brand owner, exporter, U.S. Agent, FSVP Importer or Agent, Importer of Record, customs broker, consignee, ship-to warehouse, label responsible party, and document custodian. This map should be shared with logistics partners so the same information appears consistently on invoices, packing lists, bills of lading, prior notices, entry filings, and FDA records.

Chapter 8: Documentation Checklist Before Shipping

A strong import compliance file should be prepared before products leave the foreign country. Waiting until FDA requests records is risky because FSVP, labeling, and entry documentation are not quick paperwork exercises. Supplier verification may require laboratory testing, formulation review, process information, allergen review, food safety plans, facility registration confirmation, and corrective action procedures.

Chapter 9: Common Mistakes That Lead to Detentions or Delays

The most common mistake is listing a party without permission. A foreign seller may place a consultant, warehouse, buyer, or freight forwarder on paperwork as the U.S. Agent, FSVP Importer, or Importer of Record without a signed agreement. This can result in rejected entries, broker refusal, FDA questions, or disputes between the parties. Always obtain written authorization before listing any company in an official role.

A second mistake is treating a customs broker as the compliance owner. A customs broker files entry data based on information provided by the importer. The broker may help identify missing information, but the broker is not usually responsible for creating FSVP records, approving foreign suppliers, reviewing labels, or guaranteeing FDA compliance. The importer and responsible commercial parties must provide accurate data and supporting records.

A third mistake is assuming a U.S. Agent covers FSVP. This is especially dangerous for food shipments. FDA’s FSVP rule focuses on importer verification of foreign suppliers, not merely a domestic contact name. If FDA requests FSVP records and the listed party cannot provide them, the importer may face enforcement consequences.

A fourth mistake is using inconsistent company names and addresses. The manufacturer name on the commercial invoice should align with FDA registration, prior notice, supplier records, label information, and broker instructions. Inconsistencies can trigger manual review and delays. Foreign companies should standardize legal names, physical addresses, DUNS or unique facility identifiers where applicable, phone numbers, email addresses, and contact persons.

A fifth mistake is failing to consider product claims. A cosmetic with drug claims may be regulated as a drug. A conventional food marketed with disease claims may raise drug or supplement concerns. A supplement with unsafe ingredients or missing Supplement Facts may be detained. A product category error can undermine every role assignment because the wrong regulatory pathway was selected from the beginning.

Chapter 10: Recommended Compliance Structure for Foreign Exporters

The best structure depends on the company’s size, product risk, shipment volume, and U.S. sales channel. However, a practical structure begins with a written role matrix. The role matrix should state who is responsible for FDA facility registration, U.S. Agent communications, FSVP importer identification, FSVP record maintenance, customs Importer of Record obligations, customs broker communication, label approval, product testing, complaint handling, recalls, and marketplace documentation.

For a foreign food company shipping to Amazon FBA without a U.S. buyer, the company may need a U.S.-based FSVP representative willing to be identified at entry and maintain or coordinate the required FSVP records. The company may separately need an IOR solution or customs broker arrangement. The U.S. Agent for facility registration may be the same provider or a different provider, depending on contract scope.

For a foreign manufacturer selling to a U.S. distributor, the distributor may be the U.S. owner or consignee and may act as the FSVP Importer and Importer of Record. But this should be confirmed in the purchase agreement. Some distributors expect the foreign seller to handle import compliance. Some foreign sellers expect the distributor to handle it. If the contract is silent, the shipment may be delayed when the broker asks for importer information.

For a foreign brand using a U.S. third-party logistics warehouse, the warehouse usually does not want to become the IOR or FSVP Importer. The warehouse may only receive, store, pick, pack, and ship inventory. The brand must establish separate compliance and import roles before the first shipment arrives.

Chapter 11: FAQ — U.S. Agent, FSVP Agent, and Importer of Record

Is a U.S. Agent the same as an Importer of Record?

No. A U.S. Agent is generally an FDA communication contact for a foreign facility. An Importer of Record is the customs party responsible for entry declarations, reasonable care, duties, taxes, and customs records.

Is an FSVP Agent the same as a U.S. Agent?

No. An FSVP Agent is connected to the food importer’s Foreign Supplier Verification Program responsibilities. A U.S. Agent for facility registration may only be a communication contact. The same company may offer both services, but the roles should be separately authorized.

Can Amazon be my Importer of Record?

In most seller-controlled FBA shipments, sellers should not assume Amazon will act as Importer of Record. The seller, buyer, broker, or another authorized party must be clearly identified before shipment.

Can a foreign company be the Importer of Record?

Sometimes, a foreign company may act as a nonresident Importer of Record if the transaction is properly structured and the customs broker can support the entry. This may require an importer number, bond, and proper power of attorney.

Who needs FSVP?

FSVP generally applies to many imported foods for human and animal consumption unless an exemption or modified requirement applies. The FSVP Importer must have records verifying that the foreign supplier is producing food consistent with applicable U.S. food safety requirements.

Chapter 12: Final Comparison and Best Practices

The U.S. Agent, FSVP Agent, and Importer of Record are all important, but they are not interchangeable. The U.S. Agent helps FDA communicate with a foreign registered facility. The FSVP Agent or FSVP Importer supports food safety verification obligations for imported food. The Importer of Record handles customs entry obligations and reasonable care with CBP. A compliant import plan identifies all three roles before shipping.

Best practice is to create a shipment-specific compliance packet. This packet should include the product category determination, facility registration proof, label review, ingredient review, supplier approval records, COAs, FSVP summary where applicable, commercial invoice, packing list, broker instructions, importer information, and written agreements. When the same provider performs multiple roles, the packet should clearly state which services are included and which are excluded.

For foreign exporters, this is not just paperwork. It is market access protection. A shipment delayed at the U.S. border can damage customer relationships, increase storage fees, trigger marketplace stockouts, and create reputational harm. A clear role structure helps prevent last-minute confusion and gives FDA, CBP, brokers, warehouses, and marketplaces consistent information.

Conclusion: Choose the Right Role Before You Ship

Understanding the difference between a U.S. Agent, FSVP Agent, and Importer of Record is essential for any company exporting FDA-regulated products to the United States. These roles may appear similar because all three involve U.S. import activity, but each role answers a different regulatory question. Who can FDA contact for a foreign registered facility? Who is responsible for FSVP food safety verification? Who is responsible for customs entry and reasonable care? Each answer must be clear, documented, and consistent.

Foreign manufacturers and brand owners should not wait until a shipment is already in transit to solve these questions. The best time to assign roles is during product launch planning, before labels are printed, before invoices are issued, before a broker files entry, and before inventory is shipped to Amazon or another U.S. warehouse. With the right structure, businesses can reduce import delays, respond faster to FDA or CBP questions, and build a stronger foundation for long-term U.S. sales.

If your company is preparing to export food, supplements, cosmetics, medical devices, drugs, or other FDA-regulated products to the United States, review your U.S. Agent, FSVP, and Importer of Record structure now. A small amount of planning before shipment can prevent expensive problems at the border.
