US Agent for Medical Devices

Under 21 CFR 807.40, every foreign establishment must designate a US Agent. We provide compliant US Agent services — your legal point of contact with the FDA, from registration and listing to inspection support, with bilingual coordination throughout.

Why a US Agent

Why Do You Need a US Agent?

Under 21 CFR 807.40, any establishment outside the United States that manufactures medical devices for sale in the US must designate a US Agent and complete establishment registration and device listing.

The US Agent is the legal liaison between the FDA and the foreign establishment: FDA correspondence, inspection notices and product enquiries all flow through the agent. The agent must reside or maintain a place of business in the US — a PO box or answering service alone does not qualify. Products without a designated agent may be refused entry at the border.

  • Applies to all foreign establishments (manufacturers, contract manufacturers, repackagers and more)
  • Establishment registration must be renewed each year between October 1 and December 31
  • Medical device reports (MDR) and FDA inspections require agent coordination

FAQ

Frequently Asked Questions

Who must designate a US Agent?

All establishments outside the US that manufacture medical devices for sale in the US — manufacturers, contract manufacturers, repackagers, specification developers and more — must designate a US Agent under 21 CFR 807.40.

How is a US Agent different from an importer or distributor?

The US Agent is the statutory liaison between the FDA and the foreign establishment — handling correspondence and inspection assistance. It takes no part in commercial distribution and bears no product liability. Importers and distributors are commercial roles with their own obligations; the three cannot substitute for one another.

Does the US Agent need a US place of business?

Yes. The agent must reside or maintain an actual place of business in the United States. A post-office box or answering service alone does not satisfy the FDA's requirements.

When must establishment registration be renewed?

Foreign establishments must renew their registration every year between October 1 and December 31. A lapsed registration means products cannot legally enter the US market — we remind and assist before every window.

What should I watch out for when changing agents?

A change involves FDA registration updates, correspondence handover between old and new agents, and a transition plan for responsibilities. We recommend defining the handover in the agreement — and we can manage the full switch.

How does the 510(k) relate to the US Agent?

They are independent: the 510(k) is a premarket submission, while the US Agent covers the establishment-registration and listing liaison obligations. Even before your 510(k) is cleared, you should designate an agent and register if you plan to enter the US market.

How are the fees calculated?

Fees typically comprise a contracting fee and an annual maintenance fee, determined by the number of establishments and device listings (FDA registration fees are charged separately per the FDA's current fee schedule). Submit your information via the contact page and we will quote within 24 hours.
