Primary-source references
FDA’s guidance explains that dietary-ingredient identity testing and reliance on supplier COAs are distinct requirements. A COA alone does not replace the applicable identity-testing requirement. Where reliance on a supplier COA is permitted, supplier qualification and appropriate documentation are required. Read FDA’s dietary supplement CGMP guide.
A food facility registration number is not FDA approval or endorsement of a facility or its products. Read FDA’s food facility registration Q&A. References checked November 15, 2026; your qualified team should determine the requirements applicable to your operation.
