The ZDHC MRSL conformance Levels are 1, 2, and 3. The higher the level number, the more rigorously the chemical formulation and chemical supplier practice have been reviewed.
Certification standards are widely used to measure the conformance of chemical products. Rather than creating yet another standard, we decided to leverage the existing ones. We do this by measuring how well a standard can indicate a chemical product's conformance to the ZDHC MRSL. Certified standards can be accepted by ZDHC to certify a product's performance at one of ZDHC's three conformance levels. You can find more information on ZDHC Conformance Guidance here.
No, ZDHC does not certify chemical products. The ZDHC Foundation only reviews information on third-party (independent) certification bodies, which ZDHC accepts (based on a review of their processes) as indicators of certifications for ZDHC MRSL conformance. Please see ZDHC Accepted Certification Standard for more information
