For foreign medical device manufacturers, entering the U.S. market requires compliance with regulatory requirements set by the U.S. Food and Drug Administration (FDA) . One of the key requirements is appointing an FDA Registration Agent, also known as an FDA U.S. Agent. An FDA Registration Agent for medical devices is a mandated representative for foreign manufacturers that either resides in the U.S. or maintain a place of business in the U.S. The U.S. agent supports the navigation of the legal aspects involved in entering the U.S. market. However, some foreign manufacturers are unaware that appointing a U.S. Agent for FDA registration is not just helpful; it is a legal requirement under FDA regulations. In this blog, we explain who needs a U.S. Agent, what their responsibilities are, and why choosing the right partner is critical for compliance and market access.
Compliance and Market Access Implications
Foreign medical device manufacturers that intend to import or distribute medical devices in the United States must appoint a U.S. Agent as part of their FDA Establishment Registration and Device Listing process. Only one U.S. agent should be designated. Without a designated U.S. Agent, foreign manufacturers cannot complete their registration, which means their products cannot legally enter the U.S. market. Moreover, maintaining accurate FDA registration and an active U.S. Agent is essential for uninterrupted market access. The foreign manufacturer may, but is not required to, designate its U.S. agent as its official correspondent - who is responsible for administrative tasks related to the FDA registration process.
Key Responsibilities of a U.S. Agent
The U.S. Agent plays a critical operational and regulatory role. Their main responsibility is to facilitate communication between the FDA and the foreign manufacturer.
This means the U.S. Agent acts as the primary liaison between the U.S FDA and the foreign manufacturer. This includes facilitating FDA communication, responding to (urgent) queries and submitting FDA requests for additional information or documentation. Moreover, the U.S. agent assists with scheduling and organizing FDA inspections and ensures that registrations and device listings are accurate and updated annually. Information about a foreign manufacturer’s U.S. Agent is submitted electronically using the FDA Unified Registration and Listing System (FURLS system) and is part of the registration process.
Common Misconceptions
Despite being a mandatory requirement, the role of the U.S. Agent is often misunderstood. Many foreign manufacturers assume that the U.S. Agent provides broad regulatory or quality support, but legally the scope of this role is intentionally narrow. The FDA defines the U.S. Agent primarily as a communication facilitator, not a full regulatory service provider.
To set the right expectations, it is important to clarify what the U.S. Agent is not responsible for. The U.S. Agent does not:
- Prepare or submit regulatory submissions, such as 510(k)s, De Novo requests, or PMAs;
- Manage quality system obligations or take responsibility for complaint handling, vigilance, or postmarket surveillance;
- Act as the importer or initial importer, nor assume any related supply‑chain responsibilities;
- Maintain postmarket compliance on behalf of the manufacturer.
Understanding these limitations helps manufacturers recognize why choosing a knowledgeable U.S. Agent, and when needed, a broader regulatory partner, is essential. While the legal duties of the U.S. Agent are focused on communication with the FDA, organizations like Qserve can provide additional regulatory support to help manufacturers navigate the full scope of U.S. compliance requirements.
Regulatory & Strategic Support
While the legal requirement of a U.S. Agent focuses on communication, some agents offer additional regulatory services that help manufacturers navigate the complex U.S. regulatory landscape. These services may include regulatory (strategy) consulting, compliance management support or registration guidance.
Working with an experienced U.S. Agent service provider can help foreign manufacturers reduce compliance risks, accelerate market entry, and maintain long-term regulatory confidence.
