(b) United States agent. Registrants of foreign establishments subject to this part must designate a single United States agent. The United States agent must reside or maintain a place of business in the United States and may not be a mailbox, answering machine or service, or other place where a person acting as the United States agent is not physically present. The United States agent is responsible for:

(1) Reviewing, disseminating, routing, and responding to all communications from FDA including emergency communications;

(2) Responding to questions concerning those drugs that are imported or offered for import to the United States;
