Manufacturing Audits


UL manufacturing audits help to mitigate supply chain risk, to protect brand reputation and to promote consistency through verifying quality management systems at the factory level.


UL manufacturing audits are designed to pinpoint inconsistencies, weaknesses and risks at the factory level.

Current Good Manufacturing Practices (cGMP)
Using UL’s approach to quality management, our manufacturing audits help evaluate if a U.S. Food and Drug Administration (FDA) registered factory’s quality system and operation meets or exceeds defined current good manufacturing practices (cGMP) requirements.
