Assessment of circular content in products -
Part 3: Proportion of recycled materials (Proposed Horizontal Publication)
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 corres ponding 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,

INTRODUCTION
Recycled material content is a characteristic of a product or its parts, which contributes to
material efficiency and circularity.
Focusing on the efficient and effective use of natural resources, substituting primary materials
with recycled materials reduces primary materials demand and can positively affect
environmental, societal and economic aspects. These could include reduced mining and
consumption of natural resources, reduced landfill, reduced emissions to water, air, and land,
and energy savings. The net environmental impact associated with replacing primary materials
depends on the difference in the impacts of producing raw materials from primary sources (oil,
ore, etc.) vs. reprocessing end-of-life (EoL) products or waste into recycled materials.
This document facilitates the provision of substantiated claims of the recycled content of
products. Key for substantiated claims for new products is the recognition of the chain of
custody (CoC), which refers to all players in the supply chain that take possession (custody) of
the recycled material, including manufacturers, transporters, exporters, processors and
recyclers as well as traceability, which allows to follow the movement of the recyc led materials
through the specified stages of production, processing and distribution.
Primary materials and recycled materials are often physically or chemically indistinguishable
and emerging methods for measuring the recycled content in a product or part in a reliable,
accurate and reproducible manner are currently not available. For the purpose of this document,
the verification of recycled content in a product, part of material therefore relies on documented
proof for traceability (see Clause 6) provided by the relevant actors in the chain of custody
(CoC). Recycled content is expressed as the mass ratio of recycled materials used to the total
production output of products over a specific period of time.
This document elaborates on the following aspects in assessing recycled content:
a) Description of the scope of the assessment (see 4.1);
b) Description of the system boundary for each production process in the supply chain (see
4.2 );
c) Description of the source of the recycled material inputs to each production process
(including breakdown of pre-consumer or post-consumer recycled material), and the
material composition of output products, parts or materials (see 5.4);
d) A process to trace the type of material inputs (primary and recycled materials) separately
and the link with chain-of-custody models (see Clause 6 and Annex A);
e) Balancing the input and output masses calculation, linking recycled content of products,
parts and materials in relation to total mass of materials in the products, parts and materials
produced (see 7.2).
f) Finally, 7.3 elaborates on how to calculate the recycled content of a product or its parts, as
well how to determine the recycled content of materials.
NOTE 1 Manufacturers can be product manufacturers, part manufacturers or material manufacturers.
The IEC 63333 series on ‘Assessment of circular content in products’ consists currently of the
following planned or published parts:
– IEC 63333: General method for assessing the proportion of reused components in products
– IEC 63333-3: Assessment of circular content in products - Part 3: Proportion of recycled
materials
NOTE 2 During its first review, IEC 63333 will have its number and title modified to IEC 63333 -2: Assessment of
circular content in products - Part 2: Proportion of reused content.

4 Setting the scope and system boundary of the assessment
4.1 Scope of the assessment
The users of this document performing the recycled content assessment shall define the scope
of the assessment and select its appropriate elements as detailed below. The assessment shall
be applied either to
– a product, or
– one or more parts of the product, or
– one or more materials in the product.
It is possible to perform the assessment of the product or parts at different levels, namely
– for all materials of the product or parts, or
– a type of material (e.g. plastic, metal, glass) of the product or parts (see also 5.2 for material
groups specification), or
– an individual material (e.g. polypropylene, aluminium, float glass) of the product or parts
(see 5.2 for material groups specification).
The users of this document shall determine and document the applicable elements of the scope
of the assessment, including whether the recycled content assessment is done only for the pre -
consumer recycled material or only for the post-consumer recycled material or for both.
4.2 Production process system boundaries
The users of this document performing the recycled content assessment shall identify the
system boundary for each (recycled content-related) production process which is present in the
supply chain in line with the scope of the assessment. Examples of system boundary are given
below.
a) Batch: Means a quantity of material of the same quality which is produced using uniform
production parameters at a certain manufacturing stage, stored and contained to exclude
mixing or contamination with other materials and designated as such by a single produc tion
number.
b) Production line: Means a set of interrelated or interacting activities that use inputs to
deliver an intended output. The production line can be operated as a continuous process a
semi-batch process or batch process.
c) Site: Means a location with geographical boundaries at which defined production lines under
the control of an organization are operated. For example, a site may have multiple buildings
connected by pipelines which interchange feedstock between the buildings. Sites may be in
one geographical area but need not be contiguous. For example, a road can separate two
geographical areas that are operated as a single site.
d) Sites with physical link: Means a group of sites under the control of an organisation which
are geographically distant but physically linked through the exchange feedstock, for
example through pipelines, railway, or road transportation.
e) Sites with company link: Means a group of sites under the control of an organisation which
are geographically distant and are not physically linked through the exchange of feedstock.
All sites are required to create the same material, produce the same branded product or
IEC CDV 63333-3 ED1 © IEC 2026
result in a product sold under the same trade name. The ‘sites with company link’ system
boundary separates the flow of claims from the actual material flows. In this model the
administrative record flow is not connected to the physical flow of products, p arts or
materials throughout the supply chain. As such, the actual recycled material in a product is
typically not representative of the claimed recycled content, and therefore this system
boundary is not supported by this document.
For the purpose of this document, materials that are designated as recycled material based on
‘sites with company link’ system boundary shall not be counted towards the recycled content.
4.3 Supply chain mapping
The users of this document performing the recycled content assessment shall ensure that a
mapping of the supply chain which identifies all relevant production processes which are
present in the supply chain for the scope of the assessment has been prepared .
rd
Where parts of the supply chain are covered by 3 party certificate(s) conforming with the
requirements in this document, the mapping of these parts of the supply chain production
processes is not necessary.
The supply chain mapping shall report the system boundary, CoC model (see Annex A for
details) and recycled content for each production process which is present in the supply chain
for the scope of the assessment. See Figure 1 for a graphical representation of a supply chain
mapping for a product.
IEC CDV 63333-3 ED1 © IEC 2026
Figure 1 – Graphical representation of a supply chain mapping for a product containing
plastic and steel parts (example A) and plastics parts (example B)
5 Recycled content communication and specification
5.1 Obtaining information about recycled content in the supply chain
Material declaration is a way to record and communicate the material composition, including
the recycled content contained in a product, part or material. To establish a material declaration,
each part of the product shall be assessed for the mass of its c onstituent materials, according
to the scope of assessment (see 4.1). The masses of the respective material fractions shall be
summed up to obtain the material composition of the parts or the whole product.
For communicating recycled content information related to a product, part, or material in the
value chain, material declarations should be used if available. They can be based on existing
standards such as the ISO and IEC dual logo IEC 82474-1:2025 [4] or the electrotechnical
specific IEC 62474:2018 [5].
For instance, recycled content is addressed in the ISO and IEC dual logo standard IEC 82474-
1:2025 [4] clauses 4.3 (product information), 4.5.3 (product parts in a composition declaration)
and 4.5.4 (materials in a composition declaration).

5.2 Specifying material groups
When a given material type can represent different grades of the same material, it may be
reported as a material group.
EXAMPLE Steel is produced in different grades for specific applications. The Society of Automotive Engineers lists
among others different grades of nickel-chromium steels with varying proportion of nickel and chromium, e.g. 31xx,
32xx, 33xx, 34xx.
Various grades of a material with similar physical and chemical properties may be treated as
one material group to determine the proportion of recycled content of a product.
Alloys may require the assignment to a certain material group. The users of this document shall
define the applicable material group for their product . The recycled content of the material
group shall be calculated by summing the mass of recycled material of each material grade and
dividing by the total mass of the material group.
5.3 Materials not in scope
It may be necessary to exclude parts or materials from being assigned to specific material group
due to their small size, complexity of their material composition or for other reasons, e.g.
administrative or legal. To keep the balance of mass even, these excluded parts or materials
shall be classified as "other materials" and be accounted for in the total mass of the product.
These other materials shall be treated as primary material. The users of this document may
determine limits for materials classified as other materials if applicable. They shall be justified
and documented.
5.4 Pre- and post-consumer recycled material
5.4.1 General
Recycled content is typically brought into a production process to substitute primary material.
The recycled material can be pre-consumer or post-consumer recycled material.
Only pre-consumer recycled materials and post-consumer recycled materials shall count
towards recycled content, in accordance with the definitions provided in Clause 3 of this
document and in line with specific guidance provided in Annex B for different material types.
5.4.2 Pre-consumer recycled material
Material which is or can be reclaimed and reutilized within the same process that generated it,
with only minor or no preparation (e.g. basic cleaning, cutting to size), shall not count towards
pre-consumer recycled material. This general concept can be visualized in Figure 2.
Figure 2 also shows that material processing is essentially a recycling process that includes
collection, treatment, and reprocessing of the material into raw material that can be used in
manufacturing processes.

Figure 2 – Concept of pre-consumer recycled material
Material which is or can be reclaimed and reutilized within the same process that generated it,
with only minor or no preparation (e.g. basic cleaning, cutting to size), shall not count towards
pre-consumer recycled material.
A material which is reclaimed and reutilized within the same process that generated it, as shown
in Figure 2, flowing through the “material preparation to be directly reused in process A” step,
shall retain the same pre- or post-consumer recycled content as the original material from which
it was derived. Scrap material that is not reclaimed may exit the system boundary of process A
(represented by the ‘No’ arrow to the right of the decision step (diamond)). If it undergoes a
material processing step such as recycling, it is considered pre-consumer recycled material and
can be considered as such for use in process A or other production processes. If the scrap
material does not undergo material processing, it can still be used as recovered material in
other production processes. For detailed information on specific types of materials see Annex
B.
EXAMPLE For most materials the recycled content is fixed in a process where the material is transformed from a
liquid to a solid state. In the case of steel making, the recycled content is fixed after melting and casting into a solid
slab, bloom, billet or ingot. Scrap originating from the melt shop, such as solidified steel from steelmaking vessels
(skulls) or rejected castings, would be excluded from the calculation of pre-consumer recycled material, because
they can be reclaimed within the same melting process that generated them. This is regardless of the fact that the
scrap may need to be further prepared in order to make it suitable for use in a production process, such as cutting
to certain size. In the case of plastic injection moulding, rejects from this pr ocess which are reclaimed and reutilized
within the same process would not be considered pre-consumer recycled material.
It is also important to describe where process A ends. There may be times process A includes
subsequent process steps, and the product, part or material cannot be diverted to different
processing steps until the end of that process step. At the end of proc ess A, the output can no
longer change its inherent recycled content (i.e. it is frozen or fixed). Material recovered from
further processing after process A could be included as pre-consumer recycled material,
because it has to go back to process A or it can go to another manufacturing process.
Additional guidance on material processing and whether the materials can be qualified as pre -
consumer recycled material can be found in Annex B.
5.4.3 Post-consumer recycled material
Materials obtained from end-of-life products or waste are considered post-consumer materials
(see Figure 3). Materials obtained from products that have reached the end of their life shortly
after being traded commercially or having left the final manufacturing facility are also considered
post-consumer materials. This might happen when products are damaged or cannot be sold
and remain in their distribution chain (e.g. a new version of a product replaces the previous one
which cannot be sold anymore). Materials can only be considered post-consumer material after
they were part of a finished product (for the end-user) and are subsequently discarded.
IEC CDV 63333-3 ED1 © IEC 2026
NOTE In this document, the term "finished product" is used to describe a fully assembled product. The notion of a
finished product is used to distinguish product manufacturers from material or part manufacturers. See also the
definition of finished product finished product (3.1.1.8).
Figure 3 – Concept of post-consumer recycled material
EXAMPLE Float glass used in the manufacture of a window is considered as post-consumer recycled material if it
has been assembled in an insulation glass unit that had been scrapped. Prior to this moment, it will be considered
as pre-consumer recycled material.
6 Traceability
A traceability process able to track recycled materials from when they are identified as recycled
materials by the recycler to their final application (e.g. used to manufacture a new product) shall
be implemented. Traceability information of the recycled materials is needed to calculate
recycled content.
Given that there are currently no reliable, accurate and reproducible methods available for
directly measuring the recycled content in a product, the verification of recycled content is
based solely on documentation.
For the purpose of the assessment, information allowing traceability of the recycled content in
products, parts or materials shall be gathered based on a CoC model of choice described in
Annex A. The documentation associated with the recycled content assessment, for instance the
type (pre- or post-consumer), the mass of the recycled material and the CoC model applied
shall be documented according to Clause 8.
The users of this document shall verify which CoC model is used at each production process in
the supply chain based upon the types introduced in Annex A taking into account the feasibility
of tracing recycled material inputs with each of the different methods.
The users of this document shall use the same CoC model as their supplier or, when different
types of CoC models are used for different parts or materials supplied, the u
