REACH vs. RoHS: What Supplier Data Is Different?
Compare the supplier declarations, material context and evidence workflows used for REACH and RoHS product compliance.
Guide contents
The requirements answer different questions
REACH and RoHS overlap in material and substance data but apply different legal frameworks, scopes and evidence needs.
Track declaration scope
A supplier declaration should identify the product family, material or part scope and the date or version reviewed.
Do not treat one declaration as universal proof
Evidence approved for one requirement should only be reused for another when the scope and content actually satisfy it.
