RoHS vs IEC 62443
RoHS
EU Directive restricting hazardous substances in EEE
IEC 62443
International standard for IACS cybersecurity frameworks
Quick Verdict
RoHS restricts hazardous substances in EEE for EU market access and recyclability, while IEC 62443 provides cybersecurity frameworks for industrial control systems. Companies adopt RoHS for legal compliance and global sales; IEC 62443 for OT risk management and supplier assurance.

RoHS Details
What It Is
Directive 2011/65/EU (RoHS 2) is an EU regulation restricting hazardous substances in electrical and electronic equipment (EEE). It aims to protect health and environment by limiting risks in EEE waste management, using a homogeneous material approach with maximum concentration values (MCVs): 0.1% for most of 10 substances, 0.01% for cadmium.
Key Components
- Restricts 10 substances: Pb, Hg, Cd, Cr(VI), PBB, PBDE, DEHP, BBP, DBP, DIBP.
- Annex I categories cover broad EEE scope.
- Annexes III/IV provide time-limited exemptions.
- Compliance via technical documentation, EU Declaration of Conformity (DoC), and CE marking; follows EN IEC 63000 and IEC 62321 testing.
Why Organizations Use It
Mandated for EU market access; reduces e-waste hazards, aids recyclability with WEEE. Manages supply chain risks, ensures level playing field, builds stakeholder trust amid enforcement.
Implementation Overview
Risk-based: scope analysis, BoM review, supplier declarations, tiered testing (XRF screening, ICP-MS/GC-MS confirmation), exemption tracking. Applies to manufacturers/importers of EEE; 6-18 months typical, with 10-year documentation retention.
IEC 62443 Details
What It Is
IEC 62443 is the ISA/IEC series of international standards for cybersecurity of Industrial Automation and Control Systems (IACS). It is a comprehensive, consensus-based framework providing requirements and processes for secure IACS across the lifecycle. Its primary scope covers OT environments, using a risk-based approach with zones/conduits and security levels (SL 0–4).
Key Components
- Four groupings: General (-1), Policies/Procedures (-2), System (-3), Components (-4).
- Seven Foundational Requirements (FR1–7) like IAC, RDF, RA; ~140 component requirements.
- Built on shared responsibility, zone/conduit model, SL-T/C/A triad.
- ISASecure modular certifications (SDLA, CSA, SSA).
Why Organizations Use It
- Addresses OT-specific risks (safety, availability, legacy systems).
- Meets regulatory references (e.g., NIS-2, NERC CIP alignments).
- Enables procurement assurance, supply chain risk reduction.
- Builds stakeholder trust via certified conformance.
Implementation Overview
Phased: governance (CSMS per -2-1), risk assessment (-3-2), segmentation, controls (-3-3/-4-2). Applies to critical infrastructure globally; requires audits, training. Suited for asset owners, integrators, suppliers.
