Differences Between MRSL & RSL

MRSL and RSL are terms used in relation to managing restricted substances during the manufacturing process and finished products respectively. Both are often used as chemical checklists to support product safety and chemical management activities.

However, there is often some misunderstanding and confusion between what MRSLs and RSLs are, and when to use them. Whilst both lists include similar chemistries, and both may be used for testing purposes, there are distinct differences between the two.


MRSL – Manufacturing Restricted Substances List

MRSL stands for Manufacturing Restricted Substance List, and provides manufacturers, suppliers, brands and retailers with acceptable limits of restricted substances in chemical formulations, which are used in the material and product manufacturing processes.

An MRSL is used as a tool by companies around the world to regulate the safety of chemical formulations used in manufacturing processes. The regulation of chemical formulations upstream, through an MRSL, protects workers, consumers and the environment. Adhering to an MRSL can also protect brands and retailers from any potential negative publicity on product safety.


MRSL Testing of Chemical Formulations Used in Manufacture

MRSL testing analyses the chemical formulations which are used to manufacture raw materials that go into the production of consumer goods. MRSL testing verifies the presence or absence of a MRSL restricted substances in a single chemical formulation.

MRSL testing is relevant for chemical companies, brands, retailers, and manufacturers as part of a structured due diligence testing programme, which is available as part of Chem-MAP. At Eurofins | BLC, Chem-MAP can support your business in the development of an MRSL testing programme, which is carried out at Eurofins | BLC’s UK based state of the art chemical testing laboratory.

In addition to MRSL testing, Eurofins | BLC also offers advanced technical support when failures occur, providing your business with practical solutions for your supply chain.

View more information on MRSL testing through Chem-MAP.


RSL – Restricted Substances List for Finished Products

RSL stands for Restricted Substances List and is often used as a chemical checklist when testing finished products for the presence of restricted substances. An RSL is applicable to finished articles and/or components.

An RSL is used as a tool to aid regulatory compliance to global product safety standards such as REACHCPSIACalifornia Proposition 65 and China GB Standards.

As part of a structured due diligence testing programme, chemical testing should be carried out on your finished products to ensure compliance with regulation, and your company’s RSL if applicable. Eurofins | BLC are also able to provide regulatory advice, support for chemical testing failures and chemical management solutions to support your business.
