RoHS stands for Restriction of Hazardous Substances
RoHS compliance, or the Restriction of Hazardous Substances Directive is short for “The Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment”.
The first version of RoHS Directive (2002/95/EC) was passed by the European Parliament on 27 January 2003; the European Union published the new version of RoHS Directive, RoHS 2 Directive (2011/65/EU), on 1 July 2011 and the new directive became effective on 21 July 2011, taking the place of the previous version.
In the realm of electrical and electronic products, RoHS plays a pivotal role. But what exactly is RoHS?
RoHS stands for “Restriction of Hazardous Substances.” It is a directive implemented by the European Union (EU) to regulate the presence of certain hazardous materials in electrical and electronic products. This regulation applies to a wide array of items, from small handheld devices to large household appliances.
When a product is labeled as RoHS compliant, it means that it meets the strict criteria set by the RoHS directive. This implies that the product contains only allowable levels of restricted materials. These materials include lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr6+), polybrominated biphenyls (PBBs), and polybrominated diphenyl ethers (PBDEs).
In 2015, four additional phthalates were added to the restricted list with the introduction of RoHS 2.0, further tightening the regulations.
The push for RoHS compliance emerged due to growing concerns over the environmental and health impacts of electrical and electronic waste. When products containing hazardous materials are discarded, these substances can leach into the soil and water, causing long – term pollution. For example, lead is known to be toxic to the nervous system, and mercury can have severe effects on the brain and kidneys.
By limiting the use of these hazardous materials in electrical and electronic products, the EU aims to reduce the environmental footprint of these items throughout their lifecycle, from production to disposal.
Annex I: Categories of EEE covered by this Directive
Annex II: Restricted substances referred to in Article 4(1) and maximum concentration values tolerated by weight in homogeneous materials
Annex III: Applications exempted from the restriction in Article 4(1)
Annex IV: Applications exempted from the restriction in Article 4(1) specific to medical devices and monitoring and control instruments
Annex V: Applications for granting, renewing, and revoking exemptions as referred to in Article 5
Annex VI: EU Declaration of Conformity
According to the requirement of RoHS 2 listed in Article 4, paragraph 1, Member States shall ensure that the electrical and electronic equipment (EEE) placed on the market, including cables and spare parts for its repair, its reuse, updating of its functionalities or upgrading of its capacity, does not contain the substances listed in Annex II. And substances restricted under RoHS 2.0 are listed as follows:
| Substance | CAS NO | Limit/ppm | Date of applicability | References | Scope |
| Cadmium, Cd | 7439-97-6 | 100 | 1-Jul-06 | 2002/95/EC | 1. Large household appliances. |
| 2005/618/EC | 2. Small household appliances. | ||||
| Mercury, Hg | 7439-92-1 | 1000 | 3. IT and telecommunications equipment. | ||
| Lead, Pb | 7440-43-9 | 1000 | 4. Consumer equipment. | ||
| Hexavalent chromium, Cr (VI) | 7440-47-3 | 1000 | 5. Lighting equipment. | ||
| Polybrominated biphenyls, PBBs | 59536-65-1 | 1000 | 6. Electrical and electronic tools. | ||
| Polybrominated diphenyl ethers, PBDEs | 39 mixtures | 1000 | 7. Toys, leisure, and sports equipment. | ||
| Bis(2-ethylhexyl) phthalate, DEHP | 117-81-7 | 1000 | 22 July 2019 (excluding medical devices, monitoring, and control instruments); | (EU) 2015/863 | 8. Medical devices. |
| Butyl benzyl phthalate, BBP | 85-68-7 | 1000 | 22 July 2021 ( for medical devices, monitoring, and control instruments | 9. Monitoring and control instruments including industrial monitoring and control instruments. | |
| Dibutyl phthalate, DBP | 84-74-2 | 1000 | 10. Automatic dispensers. | ||
| Diisobutyl phthalate, DIBP | 84-69-5 | 1000 | 11. Other EEE not covered by any of the categories above |
Among the above substances, four phthalates (DEHP, BBP, DBP, and DIBP) were officially included in the list of restricted substances (ANNEX II) under the amendment (EU) 2015/863 on 4 June 2015 (see our report on June 5, 2015- Four phthalates are included in the restricted substances of RoHS 2.0).
For the above restrictions, the implementation time of different types of products are different:
The RoHS directive covers a vast range of electrical and electronic products. This includes large household appliances like refrigerators, washing machines, and air conditioners, as well as small appliances such as toasters and hair dryers. IT and communication equipment like computers, smartphones, and printers, along with lighting products, electric tools, and toys, also fall under the purview of RoHS.
However, certain products, such as medical devices and monitoring and control instruments, were initially exempt but are gradually being brought under the directive’s scope in subsequent revisions.
In addition to products that RoHS Directive does not apply to, there are some products that meet the definition of the RoHS Directive, but they can’t avoid their excessive use of hazardous substances due to the reason that the existing technical means cannot find more appropriate substitutes or their substitutes are so expensive that they do not meet the demands of current social and economic benefit. In regard to these specific purposes, the RoHS Directive grants exemptions in Annex III and Annex IV, stipulating that if the product meets several certain rules, it can be launched on the EU market even if their material does not meet the limitation of quantity under the RoHS Directive.
It should be noted that the exemption is not valid all the time, and every clause of the RoHS exemption has a period of validity. So companies should keep paying attention to the latest news of RoHS exemption and replace the voided exempted materials in their products. The maximum validity period of exemptions under RoHS 2 as of 21 July 2011 are listed as follows:
| Category Annex I | The maximum validity period for new exemptions | The validity period for existing exemptions where no expiry date is specified | The validity period for existing exemptions where an expiry date is specified |
| 1-7, 10 (not applicable to Annex IV exemption) | 5 years | 22 July 2011 – 21 July 2016 | 22 July 2011 – specified date |
| 8, 9 (medical and monitoring and control devices) | 7 years | 22 July 2014 – 21 July 2021 | 22 July 2014 – specified date |
| 8 (in vitro diagnostic medical devices) | 22 July 2016 – 21 July 2023 | 22 July 2016 – specified date | |
| 9 (industrial monitoring and control instruments) | 22 July 2017 – 21 July 2024 | 22 July 2017 – specified date |
Per EU law, manufacturers, importers, and distributors of Electrical and Electronic Equipment (EEE) must ensure that their products comply with the Restriction of Hazardous Substances (RoHS) Directive. The directive prohibits using hazardous substances such as lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBBs), and polybrominated diphenyl ethers (PBDEs) in EEE. These substances threaten human health and the environment, and RoHS aims to minimize their presence in electronic products.
Failure to comply can result in legal consequences such as fines and restrictions on selling non-compliant products within the EU market. It is crucial to take RoHS compliance seriously and ensure that the products adhere to the specified substance restrictions.
Manufacturers, importers, and distributors of EEE that fall within the scope of the RoHS directive must comply with its requirements when selling their products in the European Union (EU) market. Specifically, those who must comply with RoHS include:
Suppose a product is not compliant with RoHS and placed on the European Union (EU) market. In that case, there can be legal and financial consequences for the manufacturer, importer, distributor, or any party responsible for the non-compliant product. Here are some potential consequences of non-compliance:
To avoid these consequences, businesses producing, importing, or distributing EEE should proactively ensure that their products comply with RoHS regulations. This includes conducting material assessments, testing for restricted substances, maintaining compliance documentation, and adhering to labeling and reporting requirements.
It’s also essential for businesses to stay informed about any updates or changes to RoHS regulations and regularly review and update their compliance processes to ensure that their products meet RoHS requirements.
The US Food and Drug Administration (FDA) does not require RoHS compliance for products regulated by the FDA. The FDA oversees the safety and efficacy of foods, drugs, medical devices, cosmetics, and certain radiation-emitting products in the United States.
RoHS compliance is an EU regulation that restricts the use of certain hazardous substances in EEE placed in the EU. While the FDA regulates the safety and labeling of products intended for consumption, medication, medical treatment, and certain medical devices, it does not enforce RoHS requirements.
However, suppose a company manufactures or distributes electronic medical devices or equipment that will be sold in the EU market. In that case, they may need to ensure RoHS compliance for those specific products. In such cases, businesses must adhere to RoHS regulations when exporting EEE to the EU, even if they are based in the United States.
It’s important to understand that RoHS compliance is specific to products sold in the EU and unrelated to the United States FDA regulations. Companies that market their products internationally should know and adhere to each market’s relevant regulations and requirements. Additionally, regulations and compliance requirements can change, so it’s advisable to consult with regulatory authorities or legal experts to ensure full compliance with all applicable standards and regulations.
RoHS regulations are not required globally. RoHS is a specific set of regulations established by the EU and enforced within the EU and the European Economic Area (EEA), which includes Iceland, Liechtenstein, and Norway.
The RoHS directive restricts the use of certain hazardous substances in EEE sold in the EU and EEA markets. Manufacturers, importers, and distributors must comply with RoHS regulations to sell products within these regions.
Outside the EU and EEA, countries and regions may have regulations on hazardous substances in electronics, e-waste management, and environmental protection. Still, these regulations are not RoHS per se. They can vary significantly regarding substance restrictions, requirements, and enforcement.
It’s crucial for businesses that sell electronic products internationally to be aware of and comply with the specific regulations of each market they target. Some countries and regions have adopted RoHS-like regulations, while others may have different requirements or no specific regulations related to hazardous substances in electronics.
To ensure compliance in various markets, businesses should conduct thorough research and adhere to the specific regulations and standards applicable to each region where they intend to sell their products.
