Chloris has bundled six independent certifications plus Life Cycle Assessment data behind its flagship bio-based dye, Claessen Blue™, in a move aimed squarely at brand and mill procurement teams that must trace sustainability claims to verifiable standards.

The West Jordan, Utah-based company announced the framework on 23 September 2026. Rather than marketing each certificate separately, Chloris has organized them around the due-diligence questions buyers ask when qualifying a new material.

Which standards back the claims?

The verification stack covers four procurement checkpoints:

• Bio-based origin: USDA BioPreferred® and OK biobased verify bio-based carbon content, underpinning renewable-material claims.
• Traceability: ISCC PLUS extends verification to renewable feedstocks and chain-of-custody traceability, linking raw material sourcing to industrial production.
• Chemical safety: ZDHC MRSL Level 3 and OEKO-TEX® cover chemical management and textile chemical safety requirements relevant to global sourcing and manufacturing.
• Application approval: GOTS Approved Input permits use of Claessen Blue™ within GOTS-certified textile processing, subject to applicable requirements.

The ZDHC Level 3 conformance is the tier's most demanding: it requires conformance to the Manufacturing Restricted Substances List at the highest performance level, a threshold many chemical suppliers do not reach.

Where does LCA fit in?

Chloris treats Life Cycle Assessment as a separate quantitative layer on top of certification. Certifications verify attributes, processes and compliance pathways; LCA measures environmental performance within defined life-cycle boundaries. The company says this gives brands and supply-chain partners measurable evidence across relevant environmental indicators, translating sustainability from a material claim into data that can inform sourcing and ESG decisions.

Claessen Blue™ is produced through microbial fermentation using renewable feedstocks. Chloris says the dye has been developed with three priorities in parallel: sustainability, product performance and commercial scalability.

For brands, mills and manufacturers seeking lower-impact color solutions, the company frames the objective in plain terms: make bio-based color not only innovative, but increasingly verifiable, usable and ready to scale.

What decision does this force?

The announcement targets a specific gap in dyestuff sourcing. Synthetic indigo and conventional blues carry well-documented chemical-management burdens, but bio-based alternatives have often struggled to prove feedstock origin, chain of custody and GOTS compatibility at once. Mills running GOTS-certified lines can now evaluate Claessen Blue™ as an approved input rather than requesting a bespoke compliance review.

For sourcing teams, the practical next step is supplier qualification: verify the certification scope against their own compliance requirements — ZDHC Level 3 for chemical management, ISCC PLUS for chain of custody, GOTS approval for organic processing — before trial dyeing. Chloris has effectively shifted the burden of proof from the buyer to the certificate.
