- Polybrominated Diphenyl Ethers (PBDE): < 1000 ppm
- Bis(2-Ethylhexyl) phthalate (DEHP): < 1000 ppm
- Benzyl butyl phthalate (BBP): < 1000 ppm
- Dibutyl phthalate (DBP): < 1000 ppm
- Diisobutyl phthalate (DIBP): < 1000 ppm
* PBB and PBDE are flame retardants used in some plastics.
** Two exemptions apply as per RoHS: 1. as an alloying element (in steel up to 0.35% lead by weight, in aluminum up to 0.4% lead by weight, and in copper up to 4% lead by weight); 2. in high-melting-temperature type solders (i.e. lead based alloys containing 85% or more by weight) / in solders for servers, storage and storage array systems, network infrastructure equipment for switching, signaling, and transmission, as well as network management for telecommunications / in electronic ceramic parts
