Mercury (Hg) < 1000 ppm
Hexavalent Chromium (Cr VI) < 1000 ppm
Polybrominated Biphenyls (PBB) < 1000 ppm
Polybrominated Diphenyl Ethers (PBDE) < 1000 ppm
Bis(2-Ethylhexyl) phthalate (DEHP) < 1000 ppm
Benzyl butyl phthalate (BBP) < 1000 ppm
Dibutyl phthalate (DBP) < 1000 ppm
Diisobutyl phthalate (DIBP) < 1000 ppm

Several other EU regulations are adjacent to and intersect with RoHS regulations. These include REACH, WEEE, ELV, and EU Battery Regulations.

What makes a product RoHS compliant in EU CE marking?

To make a product RoHS compliant in the European Union and eligible for CE marking, several steps must be taken to ensure that it meets the strict regulations set by RoHS. Here's a breakdown of what is involved:

Material assessment: Manufacturers must assess the materials used in their products to ensure that restricted hazardous substances like lead (Pb), mercury (Hg), cadmium (Cd), and others (such as polybrominated biphenyls) are not present above the allowable thresholds.
Substance testing: The product must undergo testing to verify that the restricted substances are either absent or meet the set limits. This can be done through lab tests and other methods, such as using XRF (X-Ray Fluorescence) for substance detection.
Material declarations: Manufacturers must provide declarations specifying the materials used in their products and confirming that the product does not exceed the allowed limits of hazardous substances.
Documentation: Manufacturers must compile technical documentation that includes evidence of RoHS compliance. This includes testing reports, material declarations, and other related documents. The documentation must be available for inspection if regulatory authorities request it.
Declaration of conformity: The manufacturer must prepare and sign a Declaration of Conformity stating that the product meets RoHS requirements. This legally binding document affirms the product's compliance with RoHS standards.
CE marking: After completing the necessary steps, the product can carry the CE mark, which signifies that it complies with RoHS and other EU regulations (such as the Low Voltage Directive and EMC Directive). The CE mark must be affixed to the product, packaging, or user manual.
Labeling: Proper labeling is essential to indicate the product's RoHS compliance. This can include marking the product with the CE logo and any relevant symbols indicating compliance with RoHS standards.
Traceability: Manufacturers must keep records that trace the compliance status of the products sold, including suppliers and component details. This is crucial for maintaining long-term compliance, particularly if changes in materials or design are made.
Ongoing compliance monitoring: Compliance is not a one-time process. Manufacturers must continue monitoring their products for ongoing compliance with RoHS standards, as changes to regulations or materials may affect compliance.

By following these steps, manufacturers ensure that their products are RoHS compliant and can be legally sold in the European Economic Area (EEA), with the CE mark confirming their conformity to these regulations.

Who must comply with RoHS?

RoHS compliance is mandatory for various parties involved in producing, importing, distributing, and selling electrical and electronic equipment (EEE) in the European Union (EU). Below is a breakdown of who must comply with RoHS:

Manufacturers

Primary responsibility: Manufacturers of electrical and electronic products are responsible for ensuring that their products meet RoHS standards. This includes conducting the necessary testing, maintaining proper documentation, and providing evidence of compliance.
Product design: Manufacturers must also ensure that the product's design does not contain restricted hazardous substances above the permissible limits and comply with labelling and CE marking requirements.

Importers

Compliance for imported products: Importers who bring electrical or electronic products into the EU market must ensure that they are RoHS compliant and provide the necessary documentation to demonstrate compliance.
Verification: Importers play a key role in verifying that the products they import into the EU market are RoHS-compliant. This often involves liaising with manufacturers or obtaining certification documents.

Distributors

Verification and documentation: Distributors must ensure that the products they sell in the EU market comply with RoHS. While they may not be directly involved in the manufacturing process, they must keep documentation to show that the products comply. They should be able to trace the product's compliance if needed.
Traceability: They are also responsible for cooperating with regulatory authorities and providing compliance information in case of inspections.

Retailers

End-sellers: Retailers selling electrical and electronic products within the EU must ensure they sell RoHS-compliant products. Although the responsibility for compliance rests mainly with the manufacturers and importers, retailers must ensure that their stock products are appropriately labeled and compliant.
Product traceability: Retailers must be able to provide proof of RoHS compliance if requested by regulatory authorities.

Third-party certifiers (Notified bodies)

When applicable: In some cases, a third-party certification body (Notified Body) may be required to verify RoHS compliance. This applies mainly to high-risk or complex products, where independent verification by a third party is necessary for compliance.
Role in certification: A Notified Body can help test, certify, and review compliance documentation before products are placed on the EU market.

parties category

Users (When modifying products)

Modifications and Compliance: If a user or third party modifies an existing RoHS-compliant product (e.g., by adding new components or changing materials), the modified product must also meet RoHS compliance standards. The responsibility for ensuring compliance typically shifts back to the manufacturer or the party modifying.

Waste management and recycling operators

Recycling Compliance: RoHS also impacts recycling and disposal operations. When products that fall under RoHS regulations are recycled or disposed of, waste management and recycling operators must follow the proper procedures for handling hazardous materials to minimize environmental impact.

In summary, everyone involved in bringing electrical and electronic products to market in the EU must ensure the product complies with RoHS standards.

What happens if a product is not RoHS compliant?

A non-RoHS compliant product can face various legal, financial, and reputational consequences. Below are the key risks and repercussions for manufacturers, importers, and distributors:

Market access restrictions

Ban on sale: No RoHS-compliant products can’t be legally sold in the European Union (EU) market. If the product fails to meet RoHS standards, it may be removed from the market and prevented from entering circulation.
Customs enforcement: RoHS non-compliant products can be held up or rejected at customs during importation into the EU. This results in delays and potential additional costs related to the return or disposal of the goods.

Fines and penalties

Financial penalties: Manufacturers, importers, and distributors of non-compliant products may face hefty fines or penalties imposed by regulatory authorities. These fines vary by jurisdiction and the severity of the violation.

Other benefits: RoHS helps create fair competition in the market by holding all manufacturers to the same standards. It also enhances overall safety by ensuring the use of safe materials.

Detecting RoHS Compounds with XRF

XRF (X-ray Fluorescence) is a nondestructive analytical technique widely used to detect and quantify the presence of hazardous substances in materials, including those regulated under RoHS (Restriction of Hazardous Substances). It is an effective tool for manufacturers, importers, and testing laboratories to ensure compliance with RoHS regulations.

How XRF Works

XRF works by exposing a material to X-rays, which cause the atoms in the material to emit secondary (or fluorescent) X-rays. These fluorescent X-rays are unique to the elements in the material and can be detected and analyzed to determine the substance's elemental composition.

The strength and energy of the emitted X-rays correlate to specific elements, allowing for precise identification and measurement of the materials present.

XRF for RoHS Testing

XRF is commonly used for RoHS compliance testing to determine whether products contain restricted substances above the allowable limits. RoHS testing with XRF can be done on various materials, including plastics, metals, and coatings. The main advantage of using XRF for RoHS testing is its non-destructive nature, which means the product does not need to be disassembled or altered for analysis.

For RoHS testing, XRF is primarily used to detect heavy metals such as: Lead (Pb), Mercury (Hg), Cadmium (Cd), Hexavalent chromium (Cr6+), Polybrominated biphenyls (PBBs), and Polybrominated diphenyl ethers (PBDEs).

When present in high concentrations, these compounds can pose significant health and environmental risks, so their presence in electrical and electronic products is strictly regulated under RoHS.

XRF devices designed for RoHS testing typically offer fast results, making them suitable for use on production lines and during quality control procedures. The results are displayed almost immediately, allowing companies to decide whether the materials meet RoHS requirements or need further processing.

Limits of XRF

While XRF is an excellent tool for RoHS testing, it does have certain limitations:

Detection sensitivity: XRF can struggle to detect low concentrations of certain substances, especially when the compounds are in tiny amounts. RoHS requires that the concentration of restricted substances be below a specific threshold (for example, 0.1% for most substances). XRF may not always be sensitive enough to detect substances near these lower limits, especially in complex materials or coatings.
Matrix effects: The material composition can affect the accuracy of XRF testing. For example, a material with a high concentration of elements similar to those tested may interfere with the readings. This can result in false positives or negatives, especially when dealing with layered or coated materials.
Surface layering issues: XRF primarily analyzes the surface layer of materials, which means that coatings or finishes could affect the results. If the restricted substances are embedded deep within the material, XRF may not detect them.
Elemental confusion: XRF can sometimes misidentify elements similar in atomic number or weight, which could lead to errors in identifying the substances present in the sample.
Limited to certain materials: XRF is most effective with metals and certain plastics. Unless specialized methods are used, it is less effective when testing materials like glass, rubber, or composites.

To ensure compliance, manufacturers and testing laboratories often combine XRF with other testing methods to verify results and comprehensively analyze product materials.

How to check RoHS compliance?

Checking RoHS compliance involves systematically assessing whether a product contains restricted substances above the permissible limits. Below is a step-by-step guide on how to check for RoHS compliance:

Review the product's technical documentation

Start by reviewing the product’s technical documentation and declaration of conformity, which is required under RoHS regulations. This document should confirm that the product complies with RoHS and specify which restricted substances are in the product and in what concentrations.

If another company manufactures the product, request the relevant compliance documents from the manufacturer or supplier. These documents should include testing results and material declarations.

Conduct material assessments

A detailed material assessment should be performed to check RoHS compliance. This involves evaluating the components and materials used in the product to ensure that they do not exceed the allowable limits of restricted substances (listed above).

Manufacturers often use material declarations from their suppliers to verify which substances are in the components of the product.

how to check rohs compliance

Perform laboratory testing

If documentation is unavailable or insufficient, laboratory testing is often necessary. Testing laboratories like Intertek or TÜV SÜD can perform RoHS testing using methods such as XRF (X-ray fluorescence) and ICP (Inductively Coupled Plasma). These tests will detect hazardous substances in the materials used in the product and provide detailed reports confirming compliance or identifying violations.

Use rohs testing tools

Several RoHS testing tools and instruments, such as XRF analyzers, are available for manufacturers to perform their testing. These devices can detect restricted substances in various materials quickly and non-destructively. They are beneficial for quality control and ensuring compliance throughout the production process.

However, it’s essential to recognize that these tools may have limitations in detecting substances at very low levels or in complex composite materials.

Third-party certification

Some products may require third-party certification by a Notified Body, especially if the manufacturer is unsure about compliance or if the product is subject to more stringent regulations. These third-party organizations, accredited by the EU, will test the product against RoHS requirements and issue a CE mark and a declaration of conformity if the product meets the standards.

Check product labeling

In some cases, products may carry the CE mark to show compliance with European regulations, including RoHS. Ensure that the product is labeled correctly. A product that carries the CE mark meets the safety, health, and environmental protection standards required by RoHS, though further documentation may still be necessary for complete verification.

Maintain Ongoing Compliance

RoHS compliance is not a one-time event. Manufacturers must ensure their products remain compliant by keeping up with regulatory changes and performing regular testing. RoHS standards can evolve, and new restricted substances can be added. Therefore, ongoing compliance monitoring is necessary to keep up with changes in legislation.

Use rohs compliance software

Various compliance software tools help manufacturers track RoHS compliance across their supply chains. These tools help manage the flow of material declarations, test reports, and certifications, making verifying compliance easier and ensuring transparency.

Engage with suppliers

Collaborate closely with your suppliers and ensure that they are also RoHS compliant. Obtain material declarations from them for each component, and request any relevant testing results. Ensure they have a robust process for maintaining compliance with RoHS standards.

How can you bring your RoHS-compliant products to the global marketplace?

Bringing RoHS-compliant products to the worldwide market involves several essential steps to ensure you meet the regulatory requirements of different countries. Here's a simplified breakdown:
