FDA对于美国代理人的解释也可以参考看一下网站的原文： Any foreign establishment engaged in the manufacture, preparation, propagation, compounding, or processing of a device imported into the United States must identify a United States agent (U.S. agent) for that establishment. Information about a foreign establishment’s U.S. Agent is submitted electronically using the FDA Unified Registration and Listing System (FURLS system) and is part of the establishment registration process. Each foreign establishment may designate only one U.S. agent. The foreign establishment may also, but is not required to, designate its U.S. agent as its official correspondent. The foreign establishment should provide the name, address, telephone and fax numbers, and e-mail address of the U.S. agent. The U.S. agent identified will be required to complete an automated process to confirm that they have agreed to act as the U.S. agent. The automated process will forward an email verification request to the U.S. agent. They will be re to confirm her/his consent to act as a representative/liaison on behalf of the foreign establishment. If the U.S. agent denies consent (or does not respond within 10 business days), the Official Correspondent/Owner Operator of the foreign establishment will be notified and must designate a new U.S. agent to satisfy the regulatory obligation.
