On April 20, 2018, the first stakeholder consultation was launched in response to the first part of the RoHS project “Study on the review of the list of restricted substances and to assess a new exemption request under RoHS 2 – Pack 15” prepared by Oeko-Institut and Fraunhofer IZM in February 2018.

The first part of the study is titled Substance Review and aims to update the existing methodology to identify and assess substances for possible restrictions, and the substance inventory, and concurrently assess a quantity of substances for future possible restriction. The study should provide technical and scientific support in view of three tasks, the information for which is planned to be collected through surveys, direct consultation and three stakeholder consultations.

This first stakeholder consultation is intended to collect information on seven substances which are pre-determined by the Commission to be assessed in task 2 for the purpose of the review and amendment of the RoHS Annex II list of restricted substances. The consultation lasts eight weeks from April 20 to June 15, 2018. The seven substances and their common uses in electrical and electronic equipment (EEE) are summarized in Table 1.

Table 1. Seven substances under assessment

  • Flame retardant synergist in plastics and rubber, such as housings for PCs, TVs, printed circuit boards, connectors, moldings, plugs and switches, wires and cables, semiconductors, ultra-pure silicon wafers and other small and large household applications
  • Melting agent in glass-ceramic hobs in household appliances and in glass for TV and PC screens
Tetrabromobisphenol A(TBBP-A) [2]
  • Reactive flame retardant in printed circuit boards (PCBs)
  • Reactive component of flame-retarded epoxy and polycarbonate resins
  • Additional reactive flame retardant in polycarbonate and unsaturated polyester resins
  • Additive flame retardant in polymeric material in housing and packaging
  • Additive flame retardant TBBP-A in acrylonitrile-butadiene-styrene (ABS) resins
Indium phosphide (InP) [3]
  • Semiconductor in electronics
Medium chain chlorinated paraffins (MCCPs) [4]
287-477-0   85535-85-9
  • Plasticizer in a wide range of applications, especially PVC, such as for EEE cable and wire sheathing and insulation
  • Plasticizer with flame retardant properties in rubber insulation and sheathing for cables and wires
  • Plasticizer with flame retardant properties in adhesives and sealants in non-foam polyurethane
  • Plasticizer in paints and varnishes used in chlorinated rubber or copolymer paints less frequently in resin-based paints
Beryllium and its compounds [5]
--  --
  • Beryllium metal and composites: optical instruments, X-ray windows
  • Beryllium-containing alloys: current carrying springs, integrated circuitry sockets
  • Beryllium oxide (BeO): In electrical/electronic articles, electrical batteries and accumulators, substrates for high power electronic devices, laser beam guidance

232-104-9 / 237-396-1
7786-81-4 / 13770-89-3
  • Nickel sulfate: In “nickel plating”
  • Nickel sulfamate: In metal surface treatment (nickel electroforming, nickel electroplating and nickel electroless technologies), in production of batteries, in production of nickel salts from nickel sulfate

Cobalt dichloride / cobalt sulfate [7]
231-589-4 /233-334-2
7646-79-9, 7791-13-1 / 10026-24-1, 10124-43-3
  • In plating processes in surface treatment (used in telecommunications, electronics, storage media, household articles)
  • In manufacture of inorganic pigments, frits, glass, ceramic ware, varistors and magnets, and in calcination/sintering processes (for semiconductors used in the manufacture of computer, electronic and optical products, electrical equipment)

Interested parties are encouraged to participate in this consultation for a better basis of fact-based evidence. The second and the third consultations are around the corner and planned to be launched in May and in fall 2018 respectively.
