What does bluesign certification mean for fabric safety?

Bluesign is a certification system that focuses on the manufacturing process rather than just the finished product. It screens chemical inputs at the beginning of the production chain using a restricted substances list (RSL) that eliminates harmful chemicals before they enter the manufacturing process. This input-stream management approach reduces chemical residues in finished products while also protecting factory workers and reducing environmental contamination.

Bluesign certification evaluates five key areas: resource productivity, consumer safety, water emissions, air emissions, and occupational health and safety. It is widely used in the outdoor industry and is recognized as a rigorous standard for responsible textile manufacturing. However, bluesign does not require organic fiber content and can certify synthetic fabrics that still shed microplastics.

For consumers, bluesign certification provides assurance that a garment was produced with restricted chemical inputs and manufactured under safer conditions. It complements OEKO-TEX (which tests the finished product) and GOTS (which requires organic content). When multiple certifications are present, the combined assurance is strongest. ONDU values transparency and supports brands that hold recognized third-party certifications.
