Part 1: General requirements
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
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 82474-1 has been prepared by IEC technical committee 111, Environmental
standardization for electrical and electronic products and systems, and Subcommittee 1:
Environmental management systems, of ISO Technical Committee 207: Environmental
management. It is an International Standard.
This first edition leverages previous work done in IEC 62474 (Material declaration for products
of and for the electrotechnical industry), extending the application of the material declaration
standard across all products of any industry sector that falls under the ISO and IEC scopes.
This edition includes the following technical changes with respect to IEC 62474:2018 (edition 2):
a) Definitions were sharpened to fulfil needs from sectors other than electrical and electronic
products and systems and new terms have been added that support new topics introduced
such as webservice methods, material efficiency and circularity, and new reference list
types.
– 6 – IEC 82474-1:2025 © IEC 2025
b) A new subclause (4.6) covering process chemical declaration was included. This subclause
covers requirements related to the information required about process chemical substances,
the applicable processes where they are used, and the respective product life cycle
phase(s).
c) A new clause (8) covering web services on material declaration was included. This clause
covers requirements related to topics such as machine-machine communication,
authentication service, and data representation.
d) Requirements and guidance for the development of reference lists such as query list (QL),
and application/exemption lists (AL/EL) were included.
This document has been given the status of a horizontal document in accordance with ISO/IEC
Directives, Part 1.

INTRODUCTION
This document benefits all industries by establishing requirements for reporting of
– substances and materials in products,
– material efficiency and circularity data,
– substances used in manufacturing and other stages of the product life cycle,
and by standardizing protocols, and facilitating the transfer, and processing of such data.
Material declarations are used by many industries to track and declare specific product
information used for compliance, the preparation of product (digital) passports and/or
environmentally conscious design (ECD) considerations. To simplify requirements across the
supply chain and to improve economic efficiencies, it is important to standardize the exchange
of product, product part, material, substance and process chemical data (including material
efficiency and circularity) and provide requirements within material declarations.
IEC 82474-1 consists of two parts: this document, which defines requirements for material
declarations, and a standard as database (SDB) which is a managed collection of information
containing the schema for data exchange format, the accompanying developer's table and other
useful information.
This document provides requirements and recommendations for the following material
declaration types:
1) Declaration for compliance – a summary declaration with reference to the declarable
substances and declarable substance groups within the declarable substance list (DSL).
The declaration for compliance provides aggregated data at the product level.
2) Composition declaration – a detailed declaration of individual materials and substances
contained in the product and product parts.
3) Process chemical declaration – a declaration of substances within a declarable substance
list used during manufacture or other product life cycle stages.
4) Material class declaration – a declaration of the types of materials (material classes) that
are present in a product.
5) Query list declaration – a declaration providing predetermined statements (queries) with
responses that are selected from a pre-defined set of choices (e.g. "True" and "False").
NOTE For the purpose of this document, product is the object of the declaration and can be a substance, material,
mixture, article or combination thereof.
IEC 82474-1 also contains requirements and guidance for the format of reference lists, such as
declarable substances lists.
IEC 82474-1 allows lists from different authorities to be used with the IEC/ISO 82474 data
exchange format.
EXAMPLE IEC 62474 DSL, automotive GADSL, aerospace AD-DSL.
The IEC/ISO 82474 SDB is maintained by a database maintenance team or SDB team (called
SDBT 82474 here) which updates information in the IEC/ISO 82474 SDB based on
requirements specified in the IEC 82474-1 standard. Other list authorities may have their own
maintenance teams, based on the rules of the specific list authority.
By fulfilling the requirements of IEC 82474-1 and based on the information from the
IEC/ISO 82474 SDB, five types of declarations can be created as mentioned above and as
shown in Figure 1.

The transmission of information in the supply chain can be done in two modes (see Figure 1):
– Requester/responder mode: The requester's specific product information is included before
the material declaration request is sent to the responder. Requester determines the type of
material declaration(s) the responder will provide.
– Distribution mode: The responder provides material declaration data about their product(s)
to a recipient.
Figure 1 – IEC 82474-1 material declaration structure and process
The IEC 82474-1 declaration requirements and guidance are described in the following clauses:
– Clause 4 specifies requirements for material declarations.
– Clause 5 together with the IEC/ISO 82474 SDB specify the material declaration data
exchange format and requirements.
– Clause 6 specifies requirements and provides guidance for developing reference lists.
Additional specifications are given in Annex A.
– Clause 7 specifies requirements and provides guidance for developing cross-sector material
class list (MCL).
– Clause 8 specifies the web services on material declarations with additional specifications
in the IEC/ISO 82474 SDB.
– Clause 9 specifies the IEC/ISO 82474 SDB maintenance process.

MATERIAL DECLARATION –
Part 1: General requirements
1 Scope
This part of IEC 82474 specifies the requirements and guidance for the content, format and
exchange relating to material declarations for products.
The main intended use of this document is to provide data up and down the supply chain that:
– allows organizations to assess products against material and substance requirements,
– allows organizations to assess process chemical substances used in manufacturing and
other stages of the product life,
– allows organizations to use this information in their activities related to environmentally
conscious design process and across all product life cycle stages,
– allows organizations to obtain information about material efficiency and circularity of their
products.
This document specifies mandatory declaration requirements and also provides optional
declaration requirements.
This document does not suggest any specific software solution to capture material declaration
data in the supply chain. However, it provides a data format used to transfer information within
the supply chain. Organizations can determine the most appropriate method to capture material
declaration data without compromising data utility and quality. This document is intended to
allow declaration based on engineering judgement, responder (supplier) material declarations,
and/or sampling and testing.
This document has the status of a horizontal publication in accordance with IEC Guide 123:2025.
