FDA Establishment Registration Lookup: Manufacturer, Importer, and US Agent Roles

Before a hospital, distributor, or acquirer signs a contract with a device company, a quiet but consequential question sits underneath the paperwork: who, exactly, does what on this device's record? The device may carry one company's brand, be built in a second company's factory, assembled to a third company's specification, sterilized by a fourth, and imported into the United States by a fifth. The fastest authoritative answer is not the supplier's organizational chart — it is the company's FDA establishment registration record, where every role is disclosed by regulation.

This article is a practical lookup workflow. It shows how to read an FDA establishment registration to identify each role — manufacturer, contract manufacturer, specification developer, repackager or relabeler, contract sterilizer, remanufacturer, reprocessor, initial importer, foreign exporter, and US agent — what each role legally means under 21 CFR Part 807, and how often each role actually appears in the registered population. It complements our broader FDA Establishment Registration & Device Listing compliance guide; that article covers who must register and the FY 2026 fees, while this one focuses on how to read and use the role information once you have it.

Why Role Identification Matters Beyond Compliance

Role data is not just for the manufacturer filling out its own FURLS forms. It is a due-diligence tool used across the supply chain:

• Hospital and GPO contracting. A value-analysis team that needs to know who actually makes, sterilizes, or relabels a private-label product can find it on the registration record rather than relying on a sales representative's assurance.
• Supplier qualification. A specification developer that outsources all manufacturing still carries the design-control and complaint obligations. Knowing whether a counterparty registers as a "specification developer" or a "contract manufacturer" changes how you audit them.
• M&A and commercial diligence. Acquirers use establishment registrations to map a target's footprint, identify undisclosed contract manufacturing relationships, and spot where a single FEI (FDA Establishment Identifier) is overloaded with roles it may not be equipped to perform.
• Complaint, MDR, and recall routing. Under 21 CFR 820.198, 21 CFR 803, and 21 CFR 806, the entity that "maintains complaint files" is a defined role. Role assignments on the registration record shape who must receive, investigate, and report adverse events.

How to Look Up an Establishment's Roles

FDA publishes establishment registration and device listing information through the FDA Establishments Database and the related Device Registration and Listing Module (DRLM) within the FDA Unified Registration and Listing System (FURLS). You can search by:

• Owner/Operator Number or Registration Number
• Establishment name (company name) or FEI Number
• Product code or device name (to find every establishment that lists that device type)

The result returns the establishment's name, address, country, owner/operator number, the devices it lists, and — critically — the establishment type field. That field is where the role information lives, and a single establishment can carry more than one role.

A few practical caveats: registration data is self-reported and renewed annually between October 1 and December 31 (21 CFR 807.25–807.27), so records can lag. An establishment that let its annual renewal lapse may still appear with a stale status. Always cross-check the registration's current status and the listed devices' premarket submission linkage (510(k), De Novo, PMA, or exemption) before relying on a record for a contracting decision.

The Establishment Roles, Explained

Under 21 CFR 807.20 and 807.40, FDA enumerates the establishment types that must register and list. Here is what each role means and the regulatory anchor for each.

Manufacturer (including kit assemblers)

The establishment that manufactures, prepares, propagates, compounds, assembles, or processes a finished device under 21 CFR 807.20(a). The manufacturer generally owns design controls, the quality system, and post-market obligations for the devices it makes. A "kit assembler" that bundles components into a finished device kit is treated as a manufacturer.

Contract manufacturer (including contract packager)

An establishment that makes a device to another party's specifications under 21 CFR 807.20(a)(2). The contract manufacturer builds the device but does not own the design; the specification developer (or brand owner) typically holds design-control responsibility. Contract manufacturers must register, and the listing must describe the manufacturing activity performed at that site.

Contract sterilizer

An establishment that sterilizes a device on behalf of another party under 21 CFR 807.20(a)(2). Sterilization is a regulated manufacturing activity, so contract sterilizers carry their own registration and process-validation obligations even though they never design the device.

Specification developer

An establishment that initiates or develops the specifications for a device that is then manufactured by a second party (21 CFR 807.20(a)(1)). This is the classic "brand owner, no factory" model: the specification developer designs the device and contracts out all manufacturing, but remains the manufacturer of record for design-control and complaint purposes. This role frequently appears together with "complaint file establishment," because the specification developer usually owns the complaint system.

Repackager or relabeler

An establishment that repackages or relabels a finished device under 21 CFR 807.20(a)(3) without changing its fundamental design. Repackagers and relabelers must register and list, and they take on labeling-compliance and UDI obligations for the configuration they create.

Remanufacturer

An establishment that remanufactures a device — processing, conditioning, renovating, repackaging, relabeling, or otherwise acting on a finished device so that its performance or safety specifications are significantly changed (21 CFR 807.20). Remanufacturers are treated as manufacturers for most regulatory purposes, including QMSR and premarket requirements.

Reprocessor of single-use devices

An establishment that reprocesses a single-use device that has previously been used on a patient (21 CFR 807.20(a)). Hospital reprocessors and third-party reprocessors must register and list, and reprocessed devices are subject to specific premarket and labeling requirements.

Complaint file establishment

An establishment that maintains complaint files as required under 21 CFR 820.198. This is often a coordinating role for distributed manufacturing networks: a single site is designated to receive, triage, and investigate complaints and to make Medical Device Reporting (MDR) decisions under 21 CFR Part 803.

Foreign exporter

A foreign establishment that exports a device to the United States but performs no other operation on the device (21 CFR 807.40(a)). Foreign exporters must register and identify the foreign manufacturers whose devices they ship.

US manufacturer of export-only devices

A domestic establishment that manufactures devices in the United States solely for export under 21 CFR 807.20(a)(2). These establishments register, but the devices are not in US commercial distribution.

Two Roles That Deserve Special Attention: Initial Importer and US Agent

Initial importer

Defined at 21 CFR 807.3(g), the initial importer is the first US-based entity that takes receipt of a device from a foreign manufacturer and furthers its marketing or distribution to the final distributor or end user — without repackaging, relabeling, or otherwise modifying the device or its labeling. The initial importer must register under 21 CFR 807.40(a), and carries complaint-handling, MDR (21 CFR 803), and corrections-and-removals (21 CFR 806) obligations for the devices it brings in.

One important nuance: with the exception of the initial importer, every registered establishment must also list its devices. The initial importer is the one role that registers but is generally not required to list the devices it imports (it can satisfy listing by providing the manufacturer's name and address). This is why an importer's record can look "thinner" than a manufacturer's — it is expected, not an error.

US agent

A US agent is a person residing or maintaining a place of business in the United States whom a foreign establishment designates as its agent (21 CFR 807.3(s)). Every foreign establishment must designate exactly one US agent as part of its registration (21 CFR 807.40(b)). The US agent is FDA's communication channel to the foreign firm: it assists FDA in communications, responds to questions about the firm's imported devices, and helps schedule inspections. If FDA cannot reach the foreign establishment directly, providing information to the US agent is legally equivalent to providing it to the foreign establishment. Changes to the US agent's name, address, or phone must be reported within 10 business days.

Unlike the EU Authorized Representative, the US agent's name and contact information appears on the registration record — not on the device labeling. A US agent may, but is not required to, also serve as the establishment's official correspondent.

Three Identifiers and Account Roles Behind Every Record

When you read a registration, three identifiers and two account-level roles govern who can act on it — and they are easy to confuse:

• FEI number (FDA Establishment Identifier). A permanent identifier tied to a facility's physical location, used across FDA centers (the same number whether the facility registers as a drug, biologic, or device establishment). One establishment corresponds to one FEI.
• Owner/Operator number. The corporation, subsidiary, or partnership directly responsible for the establishment. An owner/operator can own multiple establishments (multiple FEIs) and is the account that creates FURLS sub-accounts.
• Registration number. A separate number FDA assigns to each establishment after verifying the initial registration (21 CFR 807.35); it is sent to the official correspondent.

Two account roles in FURLS control who can file:

• Owner/Operator — the entity account that owns the registrations and listings and creates sub-accounts.
• Official Correspondent — the person the owner/operator designates to handle the annual registration, device-listing updates, and receipt of FDA correspondence (21 CFR 807.3(e)). The official correspondent can be external (a consultant or registrar) and, unlike the US agent, does not need to be located in the United States.

This last distinction matters for lookups: a foreign establishment typically has both a US agent (US-based, for FDA communications and inspections) and an official correspondent (anywhere, for the filing mechanics). The two are sometimes the same person and sometimes not — and on a due-diligence review, confirming both are current is a quick way to catch a registration that is nominally active but operationally orphaned.

How Often Each Role Actually Appears

To show how these roles are distributed in practice, we analyzed the complete FDA device establishment registration and listing dataset. The picture that emerges is one of heavy concentration in manufacturing roles and a long tail of specialized activities.

Across 24,796 unique registered establishments (by FEI):

• 14,433 establishments (about 58%) register with exactly one role, and 10,363 (about 42%) carry two or more roles. Multi-role establishments are the norm at the top of the industry, not the exception.

Counting each establishment once per role it holds, the role distribution is:

Among establishments that register with a single role, manufacturing dominates: roughly 7,525 are sole-role manufacturers, 2,823 are sole-role contract manufacturers, and 1,561 are sole-role specification developers.

The multi-role combinations are the most instructive part of the data, because they reveal how the industry actually structures a device's production:

Two patterns stand out. First, the large "Manufacturer + Contract Manufacturer" cluster (1,736 establishments) reflects OEMs that also take on contract work — a common footprint for mid-sized firms. Second, the repeated pairing of "Complaint File Establishment" with manufacturer and specification-developer roles confirms what the regulation implies: the entity that owns the design tends to own the complaint system, even when it does not own the factory.

A Lookup Checklist: Reading a Registration for Roles

When you pull an establishment's record, walk through these checks:

1. Confirm the establishment is currently registered. Check the registration status and the most recent annual-renewal fiscal year. A lapsed registration does not invalidate the device's premarket clearance, but it does render the device misbranded under section 502(o) of the FD&C Act if it is still in US distribution.
2. Read every establishment type on the record — not just the first. An establishment can list multiple roles in one record. The full role set tells you whether the site designs, builds, sterilizes, relabels, or only imports.
3. Map roles to responsibilities. Use the role list to assign design-control, complaint-handling, MDR, and corrections-and-removals responsibilities. If the record shows a "Specification Developer" plus a separate "Contract Manufacturer," your audit plan should split design controls from production controls accordingly.
4. For foreign establishments, confirm the US agent. Verify a single US agent is designated and current. If you are the foreign firm, confirm your US agent acknowledged the FDA "Action Required" notice, which the agent must respond to within 10 days.
5. For imported devices, confirm the initial importer. The initial importer carries MDR and corrections-and-removals duties for devices entering US commerce. Confirm the importer is registered and that someone at that site owns complaint intake.
6. Cross-reference listed devices. Each listed device should show its product code and, where applicable, its premarket submission number (510(k), De Novo, PMA, or HDE). A registered establishment listing devices with no submission linkage may indicate exempt devices — or a gap.
7. Flag role overload. A single small establishment holding six or more roles (manufacturer, contract manufacturer, sterilizer, repackager, complaint file, and exporter) is a concentration risk worth probing in due diligence.

Common Role Mistakes That Show Up in Registrations

• Calling a contract manufacturer a "manufacturer." The brand owner is frequently the specification developer; the factory is the contract manufacturer. Both register, but the labels matter for who owns design and complaint duties.
• Forgetting the complaint file establishment. In distributed networks, no one registers as the complaint file site, so adverse-event intake has no home. This is a frequent MDSAP audit finding.
• Overlooking the initial importer's listing exception. A buyer expecting a full device list from an initial importer may wrongly conclude the importer is non-compliant. Importers register but need not list in full.
• Treating the US agent as a regulatory partner on the labeling. The US agent is a registration and communications role. It is not named on the label and does not carry design or manufacturing responsibility.
• Letting annual renewal lapse. Registration renews every fiscal year between October 1 and December 31 (21 CFR 807.27). Changes to registration information — including role additions and US agent changes — must be reported within 30 days (10 business days for US agent changes).

Bottom Line

The FDA establishment registration record is the most reliable public map of who does what on a medical device. Reading the establishment type field — manufacturer, contract manufacturer, specification developer, repackager or relabeler, contract sterilizer, remanufacturer, reprocessor, complaint file establishment, foreign exporter, initial importer, and US agent — tells you where design, production, sterilization, complaint, and import responsibilities actually sit. In a registered population where more than four in ten establishments hold multiple roles, that mapping is usually more complicated than the org chart suggests — and it is exactly the complication a contracting or diligence team needs to see before signing.
