REACH vs RoHS
Regulatory compliance has become a cornerstone of responsible manufacturing, especially in industries like electronics, automotive, and consumer goods. Governments around the world are tightening controls on hazardous substances, forcing companies to rethink how products are designed, sourced, and distributed. For any business aiming to sell in the European Union, two regulations stand out as essential checkpoints: REACH and RoHS.
At first glance, they may seem similar—both aim to reduce the use of harmful chemicals and ensure safer products. But the differences between REACH vs RoHS are substantial, and misunderstanding them can lead to serious compliance failures.
REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) is a sweeping EU regulation that targets thousands of chemical substances across nearly every industry. It applies not just to manufacturers, but also to importers, distributors, and even downstream users.
RoHS (Restriction of Hazardous Substances), on the other hand, takes a more targeted approach. It’s focused specifically on electronic and electrical equipment, restricting a shortlist of highly toxic substances such as lead, mercury, and cadmium.
Understanding the difference between REACH and RoHS is the first step toward building a robust compliance strategy that supports both sustainability and market growth.
What is REACH?
When it comes to chemical safety within the European Union, REACH is the most comprehensive and far-reaching regulation in force. The acronym stands for Registration, Evaluation, Authorization, and Restriction of Chemicals—a fitting summary of the regulation’s multi-layered approach to chemical management.
REACH was adopted by the European Parliament in 2006 and came into effect on June 1, 2007, replacing a complex patchwork of earlier chemical legislation. The goal was clear: to streamline and improve the former regulatory framework, which had become inefficient and outdated in light of growing concerns about the long-term impact of chemicals on human health and the environment.
At its heart, REACH is a public safety regulation. It places the burden of proof on businesses to identify and manage the risks associated with the substances they manufacture and market within the EU. If the risks can’t be properly controlled, authorities can restrict or outright ban the use of those substances.
Key objectives of REACH
- Protecting human health from exposure to harmful chemicals.
- Preserving the environment by restricting the use and release of hazardous substances.
- Promoting alternative methods for assessing chemical hazards, such as non-animal testing.
- Enhancing transparency by requiring companies to disclose chemical data throughout the supply chain.
How REACH Affects the Supply Chain
REACH doesn’t just impact the companies that make chemicals—it affects every player in the supply chain, from raw material suppliers to finished product manufacturers and downstream users. Businesses are required to:
- Track and report the chemical substances used in their products.
- Communicate safety data to customers and partners.
- Substitute hazardous chemicals with safer alternatives where possible.
- Keep documentation and compliance records readily available for inspection.
In practical terms, this means companies must establish robust chemical inventory systems, ensure supplier compliance, and often engage in costly substance testing or third-party evaluations. The complexity increases with every tier of the supply chain, especially for global manufacturers sourcing materials from multiple regions.
Non-compliance doesn’t just result in penalties—it can bring production to a halt if a key material is deemed non-compliant and barred from EU markets.
What is RoHS?
If REACH is the broad umbrella covering chemical safety across industries, RoHS is its targeted counterpart—laser-focused on hazardous substances in electrical and electronic equipment (EEE). The acronym stands for Restriction of Hazardous Substances, and its purpose is clear: to keep toxic materials out of the devices we use every day.
RoHS was officially adopted by the European Union in 2003 and became enforceable on July 1, 2006, under Directive 2002/95/EC. The regulation was later recast in 2011 as RoHS 2 (Directive 2011/65/EU) and further updated in 2015 through RoHS 3 to include additional substances and stricter compliance obligations.
The catalyst behind RoHS was growing concern over e-waste, particularly the way harmful chemicals like lead, mercury, and cadmium leach into soil and groundwater from landfills. With electronics consumption rising sharply, the EU recognized the need for a unified approach to minimize environmental damage and protect public health.
The Core Objective of RoHS
At its core, RoHS aims to limit the use of specific toxic substances in electrical and electronic equipment. It targets materials that are not only hazardous during disposal, but also pose risks during production, usage, and recycling.
Currently, RoHS restricts 10 substances, including:
- Lead (Pb)
- Mercury (Hg)
- Cadmium (Cd)
- Hexavalent chromium (Cr⁶⁺)
- Polybrominated biphenyls (PBB)
- Polybrominated diphenyl ethers (PBDE)
- Four types of phthalates (DEHP, BBP, DBP, DIBP)
Manufacturers must ensure that these substances do not exceed specific concentration limits—typically 0.1% by weight (or 0.01% for cadmium) in any homogeneous material within their product.
Where REACH demands deep chemical reporting and risk assessment, RoHS is more prescriptive—providing a concrete list of banned substances and enforceable thresholds. This makes RoHS compliance slightly more black-and-white, although no less critical for companies in the electronics space.
Key Differences Between REACH and RoHS
At a glance, REACH and RoHS might appear to serve similar goals—they both aim to reduce hazardous substances in products sold within the European Union. However, a deeper look reveals that these two regulations differ significantly in terms of scope, intent, geographical reach, and substance coverage. Understanding these differences is essential for businesses navigating compliance in global markets.
1. Scope and Coverage
The most fundamental distinction in the REACH vs RoHS debate lies in the range of industries and products covered.
- REACH is comprehensive in its scope. It applies to nearly every industry that manufactures, imports, or uses chemical substances—whether in raw materials, intermediate processes, or finished goods. From cosmetics and automotive components to textiles and construction materials, REACH’s reach (no pun intended) is vast and all-encompassing.
- RoHS, by contrast, is narrower in scope, targeting only electrical and electronic equipment (EEE). Its rules apply to manufacturers and importers of everything from smartphones and servers to medical devices and household appliances.
If you’re building an electric car, for example, RoHS may apply to the dashboard electronics, while REACH governs the chemicals in the seat cushions, adhesives, and paint.
2. Focus and Intent
While both regulations aim to safeguard health and the environment, their regulatory philosophies differ.
- REACH is designed around the life cycle management of chemicals. It’s concerned with the inherent risks of thousands of substances and how they’re produced, used, and disposed of. The regulation requires businesses to identify, assess, and control risks—placing the responsibility squarely on industry stakeholders.
- RoHS, on the other hand, is more about prevention through restriction. Its intent is to ban or severely limit specific hazardous substances in electrical goods that can cause harm during manufacturing, usage, recycling, or disposal.
In other words, REACH is risk-based, requiring companies to prove that a substance is safe. RoHS is threshold-based, banning substances above a certain concentration regardless of context.
3. Geographical Scope
Both regulations originated in the EU, but their influence extends far beyond European borders—albeit in different ways.
- REACH has a direct impact on any company that manufactures or imports goods into the EU, regardless of where the company is based. Because of its expansive scope and mandatory registration processes, REACH has effectively become a global standard for chemical management. Companies exporting to Europe often align their entire product lines with REACH to avoid regulatory hurdles.
- RoHS, while also EU-centric in its enforcement, has inspired numerous national versions across the globe. Countries including China (China RoHS), India, South Korea, Japan, and the U.S. (California RoHS) have adopted similar restrictions—each with its own twist. As a result, electronics manufacturers often build to the strictest common denominator to ensure international compliance.
So while REACH sets the tone for chemical safety worldwide, RoHS is often seen as a foundational requirement for global electronics trade.
4. Substance List
The final—and perhaps most dramatic—difference lies in the volume and nature of substances regulated.
- REACH maintains a massive and evolving list of substances—over 20,000 and growing. These include carcinogens, mutagens, reproductive toxins, endocrine disruptors, and many others. The list is updated regularly, and companies must constantly monitor for Substances of Very High Concern (SVHCs) that may trigger new restrictions or authorization requirements.
- RoHS is far more concise. It currently restricts 10 specific substances (such as lead, mercury, cadmium, and flame retardants) and sets strict maximum concentration limits for each. While the list can expand—as it did in RoHS 3 with the addition of phthalates—it remains relatively targeted and stable compared to the ever-changing landscape of REACH.
This distinction is critical. REACH compliance often requires detailed chemical analysis, exposure assessments, and registration dossiers. RoHS compliance, by contrast, can be verified through material testing, supplier declarations, and product certifications.
Take proactive steps today to ensure full compliance with REACH and RoHS. Whether you’re manufacturing components, assembling finished goods, or importing into the EU, mastering these regulations is more than a legal necessity—it’s your passport to global trade and long-term market success.
