Microplastic-Free Certification for Clothing and Textiles
Independent certification for natural fiber garments, bedding, and home textiles, covering fibers, thread, trims, and finishes.
Why textiles
Synthetic fabrics shed microfibers throughout their life: in wear, in the wash, and in the dryer. Textile microfibers are among the most widely documented microplastic sources, and a growing set of natural fiber brands market their products as plastic free. The claim is harder to make than it sounds, because a cotton garment can still contain polyester thread, an elastane blend at the cuffs, a synthetic care label, or a polymer print. Certification reviews the whole garment, not just the shell fabric.
What we review
For apparel and home textiles, the entire product is treated as exposed: it sits against skin and sheds into shared laundry. Our review covers the fiber content of every fabric in the product, sewing thread, elastics and trims, labels, buttons and closures, prints and coatings, and any applied finish, all documented through the bill of materials and supplier attestations and evaluated against the published CMF Standard v1.0. Qualifying products are typically built entirely from cotton, linen, hemp, wool, silk, or other natural fibers, with natural fiber thread and trims. Synthetic fibers anywhere in the construction, including blended cuffs and polyester sewing thread, are disqualifying.
Getting started
Review the certification criteria, gather fiber documentation from your suppliers, and submit an initial application. The eligibility screening is free.

What the seal covers
- Every exposed surface: the parts that contact skin, mouths, food, or beverages during normal use
- Primary packaging where the contents touch it
- Materials, coatings, adhesives, and liners on those surfaces
- An absolute standard: no contamination threshold, no partial credit
- Annual renewal confirming materials and suppliers are unchanged
What it does not cover
- Laboratory testing of the finished product. We review documentation, not samples
- A guarantee that no microplastic particle will ever be present in or around the product
- General product safety or regulatory compliance beyond microplastics
- Chemical safety, carbon footprint, recyclability, or organic content
- Outer and shipping packaging, which we assess for shedding risk but do not certify
