After an FDA inspection with relevant results, the FDA usually expects a response within 15 days. What happens, however, if there is no response?
A South Korean company experienced that after not responding to an FDA inspection result. They received a Warning Letter and were placed on Import Alert.

Neither was there any process validation or continued process verification. Due to these deficiencies, the FDA recommended for the company to engange a consultant.
