EU discussion: Exemption for Lead Use in Certain Electrical Equipment Components

In relation to the EU's RoHS Directive, the European Commission stated on January 16, 2023, that it is looking for comments from interested parties on a request for an exemption for lead in polyvinyl chloride (PVC). The specific exemption requested relates to lead in PVC, which is utilised as a base material in sensors, which are used in in-vitro diagnostic medical equipment. 

The Member States are required by Directive 2011/65/EU on the restriction of the use of certain hazardous chemicals in Electrical and Electronic Equipment (EEE) to assure that EEE put on the market does not include the hazardous compounds listed in Annex II to that Directive.  

Of the 10 compounds that are now listed, lead is one that is considered to be hazardous. The remaining ones are bis (2 ethylhexyl) phthalate (DEHP), butyl benzyl phthalate (BBP), dibutyl phthalate (DBP), diisobutyl phthalate, cadmium, hexavalent chromium, mercury, polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE), and polybrominated biphenyl (DIBP). The materials and electronic equipment parts that are exempt from the substance limits are listed in the Directive's Annexes III and IV for possible purposes. 

It has been shown that lead is a poisonous toxin that harms the neurological system's growth, causes chronic kidney illness, and raises blood pressure. In PVC, the foundation material for sensor cards, lead is used as a thermal stabiliser. These cards are a component of disposable cartridges used in diagnostic medical analyzers that may enable precise measurement of certain analytes on a single entire blood sample, such as sodium, chloride, glucose, pH value, etc. Near the point of care, the medical analyzers are utilised to get blood results quickly (e.g., in emergency departments). Such uses were covered by an earlier exemption in Annex IV of the RoHS Directive. 

The Commission has started a feedback drive about the proposed legislative act that would grant the proposed exemption. The review period closes on February 13, 2023.
