Phthalates (DEHP, BBP, DBP, DIBP)

Four phthalate plasticisers were added to the RoHS restricted substances list by Directive 2015/863/EU, amending Annex II: bis(2-ethylhexyl) phthalate (DEHP), butyl benzyl phthalate (BBP), dibutyl phthalate (DBP), and diisobutyl phthalate (DIBP). All four are restricted at a maximum concentration value of 0.1% (1000 ppm) by weight per homogeneous material. They apply to EEE categories 1–7 and 10 from July 22, 2019; categories 8, 9, and 11 (medical devices, monitoring instruments, in vitro diagnostics) from July 22, 2021. The four phthalates are used as plasticisers in PVC and other polymers to make them flexible.

Directive 2011/65/EU, Annex II (as amended by Directive 2015/863/EU); Article 4(1).

The four phthalates are the most recent addition to EU RoHS restrictions. PVC cables, wire insulation, connectors, gaskets, keyboard membranes, and other flexible polymeric components in EEE are the primary concern. Manufacturers must systematically address all four phthalates in their supplier questionnaires and material declarations. The GC-MS test method IEC 62321-8 is required for phthalate quantification. Note that Directive (EU) 2024/232 allows continued use of recycled PVC containing lead/cadmium with stricter conditions, but phthalate restrictions in recycled PVC remain fully applicable.
