In consideration of the continuous annual increase in electronic and electrical waste, the European Commission proposed two directives, WEEE and RoHS, in April 2002 and officially published them in February 2003. The objective is to prevent hazardous substances in electrical and electronic products from harming the environment and human health. The RoHS Directive is a key green regulation that must be observed for products exported to the EU market.
It was officially implemented on July 1, 2006, and is a mandatory regulation that manufacturers, retailers, and suppliers of electrical and electronic products exported to the EU must comply with. Its main purpose is to regulate the concentration of restricted substances in electrical and electronic products, including lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr6+), polybrominated biphenyls (PBBs), and polybrominated diphenyl ethers (PBDEs). The concentration of each substance must be below the RoHS limit value of 0.1% or 1,000 ppm by weight of homogeneous material. Cadmium has a stricter limit of 0.01% or 100 ppm.
On June 4, 2015, Directive 2011/65/EU was amended by Directive (EU) 2015/863, adding four phthalates (commonly known as plasticizers), increasing the total number of restricted substances to 10. The enforcement date was July 22, 2019 for categories 1–7, 10, and 11. Categories 8 and 9 (medical devices and monitoring instruments) must comply by July 22, 2021.
In addition, on February 9, 2018, the EU launched a new RoHS revision program, known as RoHS Pack 15. In addition to reviewing restricted substances, it also evaluates new exemption applications under Directive 2011/65/EU. The German Oeko-Institut, the contracted research organization for EU RoHS, released the final report of Pack 15 on March 2, 2021, recommending the addition of medium-chain chlorinated paraffins (MCCPs) and tetrabromobisphenol A (TBBP-A) to Annex II of the RoHS Directive.

The European Union publishes weekly Safety Gate: the EU rapid alert system for dangerous non-food products notifications based on data sources including market surveillance, customs inspections, and self-reporting by manufacturers and distributors. Each EU Member State has established rules governing penalties for non-compliance with this regulation and must take all necessary measures, such as product withdrawals or recalls, the imposition of fines, and criminal sanctions.
