Certified Microplastic-Free™
Independent microplastic certification for consumer products. We verify that certified products are designed and made without microplastic-forming materials, based on documented evidence and ongoing change control.
What the seal means
The Certified Microplastic-Free™ seal tells shoppers that a product's exposed surfaces, the parts that touch skin, mouths, food, or beverages, have been reviewed against our published standard, on the basis of the product's bill of materials, supplier documentation, and manufacturing details, and determined to contain no plastics or other microplastic-forming materials.
What certification covers: Certification is a documentation-based review of a product’s exposed-surface materials against CMF Standard v1.0. It is not a laboratory test of the finished product and is not a guarantee that no microplastic particles will ever be present in or around it. See Methods Transparency for what we review and what we do not.
Many brands describe their products as plastic free. Very few can point to independent verification of that claim. Our microplastic-free certification closes that gap with a criteria-based review, a written determination, and a trademark license agreement that governs exactly how the seal may be used.
