Restricted Substances Lists (RSL) testing helps manufacturers and retailers ensure their products comply with the fast-changing regulations and standards that govern which kind of chemicals and substances can be used in products. RSL testing involves putting a product through a range of laboratory tests to ascertain which substances are used in the product, as well as reviewing the manufacturer’s product notes.

A report and certification can then be produced to demonstrate that the product is compliant.

However, restricted substance list testing, or RSL testing and ensuring RSL compliance requires you to partner with companies qualified to perform these tests.


Many restricted chemicals and substances continue to be used in the production process.
