If you operate in the food, pharmaceutical, supplement, or cosmetic industry in California, GMP Certification in California isn’t just a smart business move—it’s a competitive necessity. Good Manufacturing Practices (GMP) ensure that your products are consistently produced and controlled according to rigorous quality standards. With California being home to one of the largest health-conscious consumer bases in the U.S., getting GMP certified is a key step toward earning trust and expanding your market.

In this guide, we’ll explore what GMP certification is, why it’s especially important in California, how to get certified, and the benefits it can bring to your business.

✅ What is GMP Certification?

GMP, or Good Manufacturing Practices, refers to a set of regulations that ensure the safety, quality, and consistency of manufactured products. GMP guidelines cover all aspects of production—from raw materials and hygiene to staff training and documentation.

In the United States, GMP compliance is regulated by the U.S. Food and Drug Administration (FDA) under several parts of the Code of Federal Regulations (CFR), depending on the industry:

  • 21 CFR Part 111 – Dietary supplements

  • 21 CFR Part 210/211 – Pharmaceuticals

  • 21 CFR Part 117 – Food safety (for human consumption)

  • 21 CFR Part 820 – Medical devices

  • California Health and Safety Code – Additional requirements for manufacturers within California

Although the FDA enforces GMP regulations, certification is typically done by third-party organizations.
