FDA certification is issued directly by the Food and Drug Administration (FDA). The FDA is an agency of the U.S. federal government responsible for regulating the safety and effectiveness of food, drugs, medical devices, and other products, including approving the marketing of new products and monitoring the quality and safety of products already on the market. The certification certificate issued by the FDA is the official document after the product has been approved by the FDA, proving that the product has passed the review and evaluation of the FDA, meets the relevant regulations and standards, and can be legally sold and used in the U.S. market.
