Whether you are entering the ZDHC Gateway for the first time or upgrading your existing conformance level, IDFL offers reliable solutions tailored to your business needs. 

ZDHC MRSL Conformance Level 1: Analytical Verification

Level 1 provides the foundational proof that a chemical formulation meets the ZDHC MRSL requirements through rigorous analytical testing. Our process begins with a thorough review of the Safety Data Sheet (SDS) followed by comprehensive screening and quantitative analysis using advanced techniques such as GC/MS, LC/MS, and ICP. As a ZDHC Approved MRSL Certifier, we apply professional judgment and the ZDHC Smart Testing Grid to select appropriate test parameters, ensuring that no banned substances are intentionally used in your formulations. Level 1 certification delivers reliable, independent evidence of conformance, giving brands and suppliers confidence in your chemical products.

Benefits of Level 1:

  • Demonstrates basic MRSL compliance
  • Supports initial ZDHC Gateway listing
  • Builds confidence with brands and buyers
  • Ideal for formulators beginning chemical compliance programs

ZDHC MRSL Conformance Level 2: Management Systems Integration

Building on Level 1 analytical requirements, Level 2 introduces an on-site assessment of your facility’s management systems to demonstrate consistent, responsible manufacturing practices. Our audit evaluates your Environmental Management System (EMS), Occupational Health and Safety Management System (OHSMS), raw material supplier management, Quality Management System (QMS), Chemical Management System (CMS), and wastewater/waste/air emissions management. We also verify executive-level commitment to environmental protection and worker safety. Achieving Level 2 proves that your organization not only produces MRSL-conformant chemicals but does so within a structured framework of continuous improvement and operational control, significantly raising confidence for downstream users.

Benefits of Level 2:

  • Higher level of supply chain confidence
  • Demonstrates stronger chemical management capability
  • Supports brand sustainability and due diligence requirements

ZDHC MRSL Conformance Level 3: Chemical Hazard Assessment Capability

Level 3 represents the highest level of ZDHC MRSL conformance, combining the analytical rigor of Level 1 and the management system integrity of Level 2 with advanced Chemical Hazard Assessment (CHA) capability. During our on-site evaluation, we assess your ability to interpret toxicological and environmental data, classify formulations according to GHS, and actively track regulatory changes such as REACH, CLP, and TSCA. Level 3 also requires demonstrated reformulation expertise to replace substances of concern with safer, proven alternatives following OECD and IC2 best practices. By attaining Level 3, your company showcases leadership in sustainable chemistry, full transparency in product composition, and a proactive commitment to substituting hazardous substances—setting you apart as a truly responsible chemical formulator.

Benefits of Level 3:

  • Highest level of ZDHC MRSL assurance
  • Demonstrates industry-leading chemical stewardship
  • Strengthens trust with global brands and retailers
  • Supports long-term sustainability and ESG goals
