RoHS concentration limits are not applied to the finished product as a whole. Article 4 and Annex II work at homogeneous-material level, so the evidence package needs to trace restricted substances through materials, components, subassemblies, coatings, cables, and spare parts.
The current Annex II list covers lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE), bis(2-ethylhexyl) phthalate (DEHP), butyl benzyl phthalate (BBP), dibutyl phthalate (DBP), and diisobutyl phthalate (DIBP). Cadmium has a 0.01 percent maximum concentration value by weight in homogeneous materials; the other listed substances have 0.1 percent values. The four phthalates were added through Commission Delegated Directive (EU) 2015/863, with specific application and carve-out language for medical devices, monitoring and control instruments, cables, spare parts, and toys already covered by REACH Annex XVII entry 51.
