The RoHS directive, enforced by both EU and California RoHS law, targets electronic equipment to protect health and the environment. Manufacturers and importers must follow these regulations for compliance.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><p>RoHS restricts substances like lead, mercury, and cadmium in electronic devices.<\/p><\/li><li><p>The RoHS directive and California RoHS law ensure safer recycling and eco-friendly manufacturing.<\/p><\/li><li><p>Electronic devices covered by the RoHS directive show reduced environmental contamination.<\/p><\/li><li><p>The EU mandates compliance for electronic products, minimizing risks from electronic waste.<\/p><\/li><li><p>RoHS compliance supports global efforts to manage hazardous substances in electronic equipment.<\/p><\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" >What is RoHS Compliance?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>RoHS<\/strong> directive, known as the <strong>Restriction of Hazardous Substances<\/strong> directive, is a regulation from the <strong>European Union<\/strong>. It restricts the use of certain hazardous materials in the manufacturing of electrical and electronic equipment (EEE). First introduced in 2003 under Directive 2002\/95\/EC and now updated as <strong>Directive 2011\/65\/EU<\/strong>, the regulation is commonly referred to as <strong>RoHS 2<\/strong>, with the latest amendment <strong>RoHS 3 (Directive 2015\/863\/EU)<\/strong> effective from July 2019. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The main goal of the RoHS directive is to protect human health and the environment by limiting hazardous substances in <strong>electronic devices<\/strong>. The directive also aims to reduce the risks associated with electronic waste and to encourage safer alternatives in manufacturing.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>The RoHS directive forms part of a broader EU effort to manage electronic waste and hazardous materials.

It ensures that hazardous materials are not released into the environment during the product\u2019s lifecycle \u2014 from production to recycling. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">RoHS compliance supports:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><p><strong>Safer recycling and disposal<\/strong> of electronic waste<\/p><\/li><li><p><strong>Protection of human health<\/strong>, especially for manufacturing workers<\/p><\/li><li><p><strong>Global harmonization<\/strong> of environmental product standards<\/p><\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" >Substances Restricted by RoHS<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" >Restricted Substances List<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">RoHS currently restricts the use of <strong>10 substances<\/strong> in electrical and electronic equipment.
