What is MRSL Testing?

What is an MRSL?

MRSL stands for Manufacturing Restricted Substances List, which refers to a list of chemicals that are either restricted or banned in the manufacture of chemical product formulations. MRSLs provide limits for chemical substances used in commercially available chemical formulations, and there should be no intentional use of these substances in process chemicals used in the production of apparel and footwear.


Why are MRSLs important to chemical risk management?

MRSLs are increasingly used by brands, retailers, and manufacturers in the leather, textiles and synthetic product sectors as a way of developing sustainable chemical management, by reducing upstream chemical risk in the supply chain. This reduction in chemical risk not only helps to protect end-users and consumers of the finished product, but also helps to protect workers who come into contact with the chemical, material or product in the supply chain. The positive effects of chemical risk management through MRSL reaches further than human interaction; it also benefits the environment, including animal and plant life, as well as improving the quality of waste water and emissions from manufacturers and production facilities.


MRSL Testing

MRSL testing refers to the testing of chemical formulations against an MRSL, to identify whether any MRSL listed chemicals are present.

MRSL testing is carried out by Eurofins | BLC to the Zero Discharge of Hazardous Chemicals (ZDHC) MRSL, at our UK-based testing laboratory. Alternatively Eurofins | BLC can test to a company’s own MRSL (where applicable) upon request.


Eurofins | BLC have four MRSL testing packages available:

  • Package 1 — Complete MRSL Testing of Chemical Formulations
  • Package 2 — ‘Smart Testing’ of Chemical Formulations
  • Package 3 — MRSL Testing of Individual Analytes or Chemical Groups
  • Package 4 — Customer Specified MRSL Testing
