U.S. Agent vs Importer of Record: What's the Difference?

Understanding the U.S. Agent Role

The FDA U.S. Agent is a regulatory designation established under the Federal Food, Drug, and Cosmetic Act. Every foreign facility registered with FDA — whether for food (21 CFR §1.227), drugs (21 CFR §207.69), devices (21 CFR §807.40), or cosmetics (FD&C Act §607) — must designate a U.S. Agent who resides or maintains a place of business in the United States.

The U.S. Agent's role is specifically limited to FDA communications. They receive correspondence from FDA on behalf of the foreign facility, facilitate inspection scheduling, and forward urgent notifications. The U.S. Agent has no involvement in customs clearance, duty payments, or import logistics.

Understanding the Importer of Record Role

The Importer of Record (IOR) is a U.S. Customs and Border Protection (CBP) concept defined under 19 CFR Part 141. The IOR is the entity responsible for ensuring that imported goods comply with all applicable U.S. laws and regulations — not just FDA rules, but also customs duties, trade agreements, labeling laws, and other agency requirements.

The IOR's obligations include:

• Filing customs entries (or hiring a customs broker to do so)
• Paying applicable duties, taxes, and fees to CBP
• Ensuring that all imported goods meet U.S. regulatory requirements at the time of entry
• Maintaining records of all import transactions for five years
• Responding to CBP inquiries about the classification, value, or origin of imported goods

The IOR can be the foreign manufacturer, a U.S.-based distributor, or a third-party logistics company. Critically, the IOR assumes legal and financial liability for the imported goods at the point of entry.

Key Differences at a Glance

When You Need Both

If you are a foreign manufacturer exporting FDA-regulated products to the United States, you will almost always need both a U.S. Agent and an Importer of Record. These roles address different aspects of the import process:

• U.S. Agent: Required for your FDA facility registration. Without one, you cannot maintain an active registration, and your products will be refused entry.
• Importer of Record: Required for customs clearance. Without an IOR, your shipment cannot clear CBP and will not be released from the port.

In many cases, the IOR is a U.S.-based buyer or distributor who purchases your goods. The U.S. Agent is typically a separate service provider (like Assurentry) that handles the FDA side of things. One entity can serve in both capacities, but it is not automatic — each role must be explicitly designated.

Can the Same Entity Serve as Both?

Yes, a single entity can serve as both U.S. Agent and Importer of Record, but this is relatively uncommon. The skill sets and obligations are different: U.S. Agent work is FDA-focused, while IOR work involves customs brokerage, duty classification, and import logistics.

Some foreign facilities ask their U.S. distributor to fill both roles. This can work, but be sure to formalize each arrangement separately. Your distributor should explicitly agree to serve as U.S. Agent (and be listed in your FDA registration) and separately agree to serve as IOR (with a customs bond in place).

For most companies, working with a dedicated U.S. Agent service like Assurentry and a separate customs broker or IOR is the clearest and most reliable arrangement.
