USP: The Trusted Standard for Quality

Developing science-based public quality standards is at the core of what we do. USP standards provide a common quality benchmark—a set of characteristics, processes and guidelines that apply regardless of where a product or ingredient is manufactured. Through our critical work, we collaborate with national regulatory authorities, international agencies, and companies around the globe to help ensure quality. With more than 200 years of experience building quality foundations for a healthier world, USP is uniquely positioned to provide comprehensive, evidence-based verification services.
