FAQs

It means a product has been reviewed against our published standard and found to meet defined criteria based on materials, formulation, and manufacturing documentation. The certification is designed around upstream prevention and transparency.

Not as a routine requirement today. Current microplastics analysis methods are technically complex and results can vary by method, size thresholds, sample preparation, and instrumentation. The European Commission’s Joint Research Centre reported average analysis times per sample of about 10 hours (µ-FTIR) and 19 hours (µ-Raman), and noted that time and time-related costs are barriers to routine analysis. JRC technical report.

For broad consumer-product certification, documentation-based verification is the most consistent and scalable approach right now. We may introduce lab testing as an optional add-on as methods become more standardized and commercially practical.

Microplastics risk is largely determined by upstream choices: material composition, coatings, additives, and degradation pathways. A documentation-first review focuses on preventing microplastic introduction at the design and manufacturing stage rather than relying solely on post-production detection.

We review materials declarations, technical data sheets, supplier documentation, bills of materials, and manufacturing disclosures relevant to microplastic-forming inputs. Requirements vary by product category and risk profile.

It does not claim a universal, absolute zero across all particle sizes and conditions, and it is not a statement that the product has been lab-tested for microplastics by CMF unless explicitly stated in the client’s certification scope.

Eligibility depends on category, materials, and documented risk. Products designed around inert materials with minimal coatings and additives tend to be the fastest fit. We publish criteria so brands can self-screen before applying.

Certification lasts 1 year. If a product’s materials, suppliers, or manufacturing process changes, re-review may be required.
