The European Union prescribes that chemicals restricted by the RoHS directive should be reviewed by the European Commission periodically. The RoHS directive restricts the use of certain hazardous substances in Electrical and Electronic Equipment, vide Directive 2002/95/EC.

In this context, the European Commission has asked specific agencies to study the feasibility and need for inclusion of other chemicals into the purview of the RoHS directive. The studies, though not ratified by the European Commission, throw light on the potential chemicals that may be regulated by the RoHS directive.

The candidates for a potential inclusion into the RoHS Directive and their chemical names are:

1. Tetra Bromo BisPhenol-A (TBBP-A)

2. Hexa Bromo Cyclodo Decane (HBCDD)

3. Bis (2-Ethylhexyl) Phthalate (DEHP)

4. Butyl Benzyl - Phthalate (BBP)

5. Di Butyl Phthalate(DBP)

The proposed policy options for each of the candidate substances are listed below:

TBBP-A
Policy option-3: Add for all EEE in the scope of RoHS with possible exemptions. Provide a transition period of 24 months for the phase out of TBBP-A, used as additive flame retardant. 36 months recommended for phase out of TBBP-A used as reactive flame retardant.

HBCDD
Policy option-4: Add HBCDD for all EEE in the scope of RoHS without exemptions. A transition period of 24 months is recommended.

DEHP
Policy option-3: Add DEHP for all EEE in the scope of RoHS with possible exempted applications. A transition period of 24 months is recommended.

BBP
Policy option-3: Add BBP for all EEE in the scope of RoHS with possible exempted applications. A transition period of 24 months is recommended.

DBP
Policy option-3: Add DBP for all EEE in the scope of RoHS with possible exempted applications. A transition period of 24 months is recommended.
