Materials & Substances Declaration Development Document

This updated resource offers expanded guidance on calculating substance content in products, with particular emphasis on complex and often misunderstood topics such as reactive and transformational materials—materials whose final composition changes after processing (for example, two‑component coating systems).

The enhanced document includes:

• Practical insights for identifying substances and performing mass calculations
• Step‑by‑step examples, including a complex article featuring multi‑part materials with volatile and reactive components
• A worked example for jacketed cable calculations
• A homogeneous material (RoHS) declaration example
• Additional context on Safety Data Sheets, surface finishing processes, and a curated list of references, tools, and websites to support more accurate declarations
