What is RoHS-Restriction of Hazardous Substances
RoHS, stands for Restriction of Hazardous Substances, is a directive that originated in the European Union (EU) but has gained global significance. The RoHS Directive restricts the use of certain hazardous substances in electrical and electronic equipment (EEE) to protect human health and the environment.
Here are some key points about RoHS:
Purpose: The primary objective of RoHS is to minimize the risks associated with hazardous substances in EEE, both during the manufacturing process and at the end of their life cycle. The directive aims to reduce the environmental impact caused by the improper disposal or recycling of EEE containing hazardous substances.
Restricted Substances: It restricts the use of six hazardous substances in EEE. These substances include lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (CrVI), polybrominated biphenyls (PBBs), and polybrominated diphenyl ethers (PBDEs). So, The maximum allowable concentration of these substances in homogeneous materials of EEE is 0.1% by weight, except for cadmium, which has a limit of 0.01%.
Scope: It applies to a wide range of electrical and electronic products. Including large and small household appliances, IT and telecommunications equipment, consumer electronics, lighting equipment, medical devices, electrical tools, toys, and more. The directive covers both the manufacturing and importation of EEE into the EU market.
Compliance and Certification: Manufacturers and importers are responsible for ensuring their products comply with this requirements. They are required to carry out testing, document their conformity, and affix the CE marking to indicate compliance. Restriction of Hazardous Substances compliance is typically self-declared, although market surveillance authorities may conduct checks and request supporting documentation.
Global Impact: Although RoHS originated in the EU, its influence has extended beyond European borders. Many countries and regions around the world have enacted similar regulations, often referred to as “RoHS-like” or “RoHS-inspired” regulations. Examples include China RoHS, Korea RoHS, and Japan RoHS. Therefore, These regulations may have variations in the list of restricted substances and concentration limits.
Benefits: The implementation of RoHS and similar regulations brings several benefits. It reduces the release of hazardous substances into the environment, protects human health and occupational safety, encourages the development of environmentally friendly products. Also, it promotes the recycling and proper disposal of EEE, and fosters sustainable practices in the electrical and electronic industry.
So, It’s important for manufacturers, importers, and distributors of electrical and electronic equipment to stay updated with RoHS requirements and ensure compliance to meet legal obligations and maintain market access.

RoHS compliant refers to products or components that meet the requirements of the RoHS (Restriction of Hazardous Substances) directive. So, Being RoHS compliant means that the product or component has been manufactured or designed in adherence to the restrictions on the use of specific hazardous substances outlined in the directive.
What are the requirements of RoHS?
Restricted Substances: The Restriction of Hazardous Substances directive restricts the use of six hazardous substances in EEE. These substances are:
a. Lead (Pb)
b. Mercury (Hg)
c. Cadmium (Cd)
d. Hexavalent chromium (CrVI)
e. Polybrominated biphenyls (PBBs)
f. Polybrominated diphenyl ethers (PBDEs)
Maximum Allowable Concentration: The maximum allowable concentration of these restricted substances in homogeneous materials of EEE is 0.1% by weight, except for cadmium, which has a limit of 0.01%. Homogeneous materials are those that cannot be mechanically disjointed into different materials.
Compliance Documentation: Manufacturers or suppliers of EEE must ensure compliance with RoHS requirements. This includes maintaining documentation and records to demonstrate conformity. So, Compliance documentation may include material declarations, supplier declarations of conformity, test reports, or other relevant evidence.
Exemptions: This directive includes specific exemptions for certain applications where the restricted substances may still be allowed in limited quantities due to technical or safety reasons. These exemptions are defined in the directive and subsequent amendments. Therefore, Manufacturers need to assess if their products fall within any applicable exemptions and document their justification if they utilize them.
Compliance Assessment: Compliance with this standard is typically determined through testing and analysis of materials used in the production of EEE. This involves verifying the concentration levels of the restricted substances in the homogeneous materials. So, Testing can be conducted internally or by third-party laboratories.
CE Marking: RoHS compliance is often self-declared by manufacturers or suppliers. They may affix the CE marking (Conformité Européene) on their products to indicate conformity with this requirements. Therefore, The CE marking is a declaration by the manufacturer that the product meets the essential requirements of all applicable EU directives, including Restriction of Hazardous Substances.
It is important to note that RoHS compliance is required for products sold in the European Union (EU) market. Additionally, other countries and regions, such as China, Japan, Korea, and others, have implemented similar regulations with their own specific requirements. Therefore, Manufacturers need to consider the specific regulations applicable to the markets where their products are sold to ensure compliance with RoHS or related regulations.
