An established list of chemicals is used to help brands and retailers communicate to their supply chains substances that should not be used or used with restrictions in their end products. This list is commonly known as Restricted Substance List (RSL), and it contains several substances that are dangerous for human health and the environment, together with their related limits and test methods.

These limits may be aligned with existing regulations or set up by the brand or the retail companies with the support of chemical experts based on the safety concerns related to specific substances.

Why is a Restricted Substances List important?
Setting up an RSL is a fundamental step of a chemical management strategy that any company should develop to manage risks related to the presence of dangerous chemicals in the end product. The absence of a reference document such as an RSL may be critical for any company to monitor the chemical legislation in place in a specific country, to ensure a high level of protection of consumer and protecting the brand reputation.

In addition, an RSL helps to communicate rules related to chemicals to all parties in the supply chain.

Restricted Substance Management
The RSL is the core of the Restricted Substance Management, that can be summarized in the following key points:

  • Restricted Substances List Policy
    • Based on regulatory requirements, industry practice and failure history
      • Reviewed by various approaches such as Restricted Substance Group comparison and detailed individual substance requirement comparison
    • Program manual and risk-based testing matrix
      • To establish a good communication between vendors, testing lab and the brand
      • To create declarations and collaborate with legal counsel teams responsible for supply chain contracts
      • Product management and testing teams dedicated to frame an RSL matrix
      • To create a manual that will be included in the brand internal and external policies, inclusive of tools such as Test Request Form, and how to submit samples and training tools
  • Provide training
    • Educate the factories, vendors, sourcing teams, QA teams, etc.
  • Test data management
    • Testing data storage
    • Testing data mining and analysis
  • Control and validation
    • Failure management – corrective and preventive actions
    • Policy review and update
