My customer has sent me a “material declaration”; why does it ask for information on substances not covered by RoHS?
Material Declarations are prepared by electrical and electronic OEMs and companies throughout the supply chain. Rather than being specific to RoHS, they are a compilation of all requirements concerning restricted substances world wide. Those requirements may be from regulations or they may be something your customer wants or needs. Material Declarations also include elements or compounds that are not restricted but either may become restricted or are needed by the company to assess other issues, such as residual value. For example, it is desirable to know the gold content of a material even though gold is not restricted, since the material may have residual value depending upon its mass and gold content.
