Overview

IEC 62474:2012 is an international standard published by the International Electrotechnical Commission (IEC) that defines the material declaration requirements for products in the electrotechnical industry. It establishes a harmonized process, specifying the content and format for declaring materials and substances used in electrical and electronic products. This standard primarily supports companies operating within or supplying the electrotechnical industry by providing clear rules on how to report materials to ensure compliance with substance restrictions and facilitate environmentally conscious product design.

By adhering to IEC 62474, organizations can promote transparent supply chains, improve environmental responsibility, and streamline communication of material data throughout all phases of a product’s lifecycle. The standard does not cover process chemicals or emissions during product use.

A key resource accompanying IEC 62474 is a dedicated online database (http://std.iec.ch/iec62474) which contains:

• Declarable substance groups and individual substances
• Reference substances for identification
• Material classes applicable to electrotechnical products
• An XML schema to support standardized data format and exchange

Key Topics

Material Declaration Requirements

IEC 62474 provides comprehensive guidelines on the mandatory and optional data that must be declared. This includes:

• Identification of products and product parts
• Substance groups and substances with reporting obligations
• Material classes and their criteria
• Threshold levels for declarable substances to be reported

Data Format and Exchange

The standard defines a common XML format for data exchanges between supply chain partners, enabling seamless integration and automated reporting processes. It supports both one-way and two-way data exchanges and includes a developer table to assist implementation.

Compliance and Environmental Impact

Material declarations documented under IEC 62474 support organizations in:

• Assessing compliance with substance restriction regulations (e.g., RoHS, REACH)
• Integrating material data into eco-design processes
• Managing product lifecycle environmental impacts effectively

Database Management

The IEC 62474 database is regularly maintained and updated through a structured process, including:

• Adding or reclassifying substances
• Removing obsolete substances
• Maintaining data format standards for interoperability

Applications

IEC 62474 is essential for companies involved in the design, manufacturing, distribution, and supply of electrotechnical products, including:

• Electrical equipment manufacturers
• Electronic component suppliers
• Environmental compliance and regulatory bodies
• Supply chain managers seeking transparency on the use of restricted substances
• Product designers implementing eco-friendly materials management and sustainable design methodologies

Applying IEC 62474 ensures:

• Streamlined material transparency in global supply chains
• Facilitation of regulatory compliance audits and support for certification procedures
• Enhancement of product sustainability, contributing to corporate social responsibility goals
• Reduction of risks associated with hazardous materials and associated environmental liabilities

Related Standards

IEC 62474 interfaces with other standards and regulations such as:

• RoHS (Restriction of Hazardous Substances Directive) which restricts certain hazardous materials in electrical and electronic equipment
• REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals), an EU regulation controlling chemical usage and disclosure
• ISO 14000 series for environmental management, supporting eco-design and lifecycle assessment
• Other IEC standards that pertain to environmental aspects of electrical and electronic products

Adopting IEC 62474 serves as a foundation for fulfilling increasingly stringent international material and environmental regulations.

MATERIAL DECLARATION FOR PRODUCTS OF AND FOR

THE ELECTROTECHNICAL INDUSTRY
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

INTRODUCTION
The electrotechnical industry tracks and declares specific information about the material

composition of its products for compliance and environmentally conscious design

requirements. The electrotechnical industry needs to gather information about the composition

of products and product parts that are purchased from suppliers for incorporation into their

products. Currently material declarations are driven by individual product manufacturer’s

specifications and there is no internationally accepted standardization. This results in

economic inefficiencies. To simplify requirements across the supply chain and to improve

economic efficiencies, it is necessary to standardize the exchange of material composition

data and provide requirements for material declarations.

This International Standard benefits the electrotechnical industry by establishing requirements
for reporting of substances and materials, standardizing protocols, and facilitating transfer
and processing of data.
62474  IEC:2012 – 7 –
MATERIAL DECLARATION FOR PRODUCTS OF AND FOR

THE ELECTROTECHNICAL INDUSTRY
1 Scope
This International Standard specifies the procedure, content, and form relating to material
declarations for products of companies operating in and supplying the electrotechnical

industry. Process chemicals and emissions during product use are not in the scope of this

International Standard.
The main intended use of this International Standard is to provide data to downstream
manufacturers that:
• allows them to assess products against substance restriction compliance requirements
• they can use in their environmentally conscious design process and across all product
life cycle phases
Clause 4 specifies requirements for a material declaration.
Clause 5 specifies the criteria for declarable substances and material classes in the
IEC 62474 database associated with this standard.
Clause 6 specifies the data format and exchange requirements to be included in the
IEC 62474 database.
Clause 7 specifies the process to regularly update and maintain the IEC 62474 database.
Although this International Standard specifies base requirements, it offers flexibility to product
manufacturers and suppliers in the selection of additional requirements or information.
This International Standard does not provide any specific method to capture material
composition data. Organizations have the flexibility to determine the most appropriate method
to capture material composition data without compromising data utility and quality. This
International Standard is intended to allow reporting based on engineering judgment, supplier
material declarations, or on sampling and testing.

4.2 Base data requirements
4.2.1 Products
The following requirements shall apply to products:

a) A material declaration shall be provided for a product or product family.

NOTE 1 Only the supplier is likely to know the appropriate product family groupings for material declaration
purposes based on their technical knowledge of product material content.

b) The product shall have an identification and a mass assigned. In the case of a product

family, the identification and mass of each product within the product family shall be

specified.
NOTE 2 When each product in the product family has the same mass, it is sufficient to provide this mass just
once.
4.2.2 Product parts
Product parts shall be declared if a substance group or substance in the IEC 62474 database
refers to this part in the reporting threshold level and its reporting threshold level is exceeded.
NOTE Examples for such product parts are when batteries are incorporated into a printed circuit board assembly.
If such product parts need to be declared, the following shall apply:
a) Product parts shall be assigned to the product;
b) Product parts shall have an identification assigned;
c) Product parts shall have a mass or percentage of the product mass assigned.
4.2.3 Substances or substance groups listed in the IEC 62474 database with a
mandatory reporting requirement
Substances or substance groups listed in the IEC 62474 database with a mandatory reporting
requirement shall be declared if they are present in the product at or above the reporting
threshold level given in the IEC 62474 database and if the reportable application as listed in

the IEC 62474 database is applicable for that substance or substance group.
NOTE 1 When such substances or substance groups are not declared in a material declaration, they are not
present over the specified threshold, but could be present below this threshold or the reportable application as
listed in the IEC 62474 database is not applicable.
If such substances or substance groups are present above the reporting threshold level given
in the IEC 62474 database and if the reportable application as provided in the IEC 62474
database is applicable, the following requirements shall apply:

a) Such substance groups shall be assigned to the product part (if 4.2.2 applies) or
otherwise to the product. Such substances shall be assigned to the substance group (if
the substance group has a mandatory reporting requirement) or otherwise to the product
part (if 4.2.2 applies) or otherwise to the product.
b) Such substances or substance groups shall be named as given in the IEC 62474 database.
c) In general, such substance groups or substances shall have a mass or percentage of the
product part mass (if 4.2.2 applies) or otherwise a percentage of the product mass
assigned. If such substance groups or substances have reporting threshold levels
specified in the IEC 62474 database, referring to the material, they shall have a material
mass percent assigned.
NOTE 2 The IEC 62474 database lists some substance groups that require reporting as percentage of the
material mass.
NOTE 3 The reporting requirement as percentage of the material mass can differ e.g. the numerator for this
percentage can be the sum of the masses of all substances belonging to this substance group present or just the
mass of a specific element. Details are given in the IEC 62474 database.

requirement shall be declared if they are present in the product at or above the threshold level

given in the IEC 62474 database and if the reportable application as listed in the IEC 62474

database is applicable for that substance or substance group. Substances and substance

groups with a mandatory reporting requirement in the IEC 62474 database may be declared if

they are present in the product below the threshold level given in the IEC 62474 database or
if the reportable application as listed in the IEC 62474 database is not applicable for that
substance or substance group.
NOTE 1 When such substances or substance groups are not declared in a material declaration, they are not
present over the specified threshold, but could be present below this threshold or the reportable application as
listed in the IEC 62474 database is not applicable.
The following requirements apply to such substances or substance groups when declared:
a) Such substance groups shall be assigned to the material (if material is declared), to the
product part (if product part is declared) or otherwise to the product. Such substances
shall be assigned to the substance group (if substance group is declared) or to the
material (if material is declared) or to the product part (if product part is declared) or
otherwise to the product.
b) Such substances or substance groups shall be named as given in the IEC 62474 database.
c) In general, such substance groups or substances shall have a mass or percentage of the
material mass (if material is declared) or a percentage of the product part mass (if product
part is declared) or otherwise a percentage of the product mass assigned. If such
substance groups or substances have reporting threshold levels specified in the
IEC 62474 database, referring to the material they shall have a material mass percent
assigned.
NOTE 2 The IEC 62474 database lists some substance groups that require reporting as percentage of the
material mass.
NOTE 3 The reporting requirement as a percentage of the material mass can differ e.g. the numerator for
this percentage can be the sum of the masses of all substances belonging to this substance group present or
