IEC 82474-1:2025

Overview

IEC/ISO 82474-1:2025 - Material declaration - Part 1: General requirements is the new horizontal standard that defines requirements and guidance for material declarations across supply chains. Published as a dual-logo IEC/ISO standard (Edition 1.0, 2025), it specifies what information suppliers and manufacturers should provide about materials, substances and process chemicals, how that information can be formatted and exchanged, and how it supports material efficiency and circularity objectives.

Key topics and technical requirements

• Scope and intent: Enables data flow up and down the supply chain to assess products against substance restrictions, support environmentally conscious design, and inform circularity and material-efficiency decisions.
• Mandatory and optional declarations: Defines both required declaration elements and optional data to increase transparency (e.g., composition, compliance and process chemical declarations).
• Composition and substance declarations: Provides models and requirements for composition declarations, including Full Material Declaration (FMD) and Full Substance Declaration (FSD) possibilities.
• Process chemical declaration (new): Clause 4.6 introduces requirements for declaring process chemical substances, their applicable manufacturing processes and life-cycle phases.
• Data exchange format (DXF): Specifies a data exchange format to transfer material declaration data (file formats, one-way/two-way exchanges) while allowing organizations to choose their own capture methods.
• Web services for machine-to-machine exchange: Clause 8 describes requirements for web services (authentication, data representation, machine-to-machine communication).
• Reference lists and maintenance: Requirements and guidance for reference lists such as Declarable Substance Lists (DSL), Query Lists (QL), Material Class Lists (MCL), Application/Exemption Lists (AL/EL) and their change‑management.
• Horizontal status & updates: Adopted as a horizontal publication (IEC Guide 123 / ISO/IEC Directives) and includes updates from IEC 62474:2018 (sharpened definitions, new webservice and circularity topics).

Practical applications and who uses it

This standard is practical for:

• Manufacturers and suppliers providing product material information to customers.
• Compliance, EHS and regulatory teams assessing conformity to substance restrictions and reporting obligations.
• Product designers and sustainability teams integrating material-efficiency and circularity data into design decisions.
• Supply‑chain software vendors and data integrators implementing DXF and web services for automated exchange.
• Standardization bodies and reference-list maintainers setting DSL, MCL, QL and AL/EL governance.
