Marabu is proud to announce a significant milestone in its sustainability journey: the expansion of its ZDHC Level 3 certified portfolio to fifty products. This achievement reflects a deep commitment to responsible chemical management and to supporting cleaner, safer production across the textile, leather, and fashion industries.

Understanding ZDHC Certification

The Zero Discharge of Hazardous Chemicals (ZDHC) Foundation is an environmental organization working to remove hazardous chemicals from supply chains. To help companies improve their chemical management, ZDHC created a three‑level certification system that checks whether products meet strict safety standards and contain no substances banned under the ZDHC Manufacturing Restricted Substances List (MRSL).

The ZDHC certification process looks at how chemicals are used and managed, including what ends up in wastewater. Below is a breakdown of the three levels:

• Level 1 confirms basic documentation and testing.
• Level 2 adds deeper checks to show more consistent compliance.
• Level 3 is the highest level and requires strong, verified systems that ensure chemicals remain safe over time. This includes MRSL testing and on‑site audits of chemical management practices.

Why Level 3 Matters

Level 3 certification offers the strongest assurance that a chemical product is safe for workers, consumers, and the environment. Because Level 3 requires ongoing verification, not just a one‑time test, it helps ensure long‑term reliability. It also gives brands clearer visibility into the chemicals used in their supply chains, which supports responsible sourcing and more accurate sustainability reporting.

For Marabu, reaching Level 3 for fifty products shows that our internal processes are robust and that we are committed to supporting our customers with the safest and most transparent solutions possible.

Why ZDHC Certification Is Important

Sustainability discussions often focus on carbon emissions, but chemical pollution, especially found in water, remains a major global concern. ZDHC was founded in 2011 to address this issue and to help industries reduce their use of hazardous substances.

By earning ZDHC certification, companies demonstrate that they take chemical safety seriously. They want to work toward the shared goal of zero discharge of hazardous chemicals. As a supplier of textile printing inks, Marabu can make a meaningful contribution by offering safer alternatives that help our partners reduce their environmental impact.

Supporting Customers in Their Sustainability Goals

Many companies are working toward ambitious sustainability goals, and choosing ZDHC‑certified products helps them move in the right direction. With a wide range of Level 3 certified solutions, Marabu gives customers the confidence to make responsible sourcing choices. Our aim is to support partners in meeting their environmental commitments while still delivering the performance and quality they expect.

We encourage customers to use the ZDHC ChemCheck tool to confirm that their suppliers’ chemical formulations meet MRSL requirements. ChemCheck provides a verified product passport, making it simple to ensure that the chemicals used in production align with ZDHC standards.

What’s Next for the Industry?

As the industry continues to move toward more transparent and safer chemical practices, ZDHC certification will play an increasingly important role in shaping responsible production. Companies that invest early in strong chemical management systems will be better prepared for rising expectations from brands, regulators, and consumers. By expanding our Level 3 certified portfolio, Marabu is taking an active role in this transition and helping to build a future where safer chemistry is the standard.
