IEC 62474 Updates to Declarable Substances List (DSL) – 2022 January

The IEC 62474 declarable substance list (DSL) was updated on January 17, 2022, coinciding with ECHA’s update to the EU REACH Candidate List.  IEC 62474, the International Standard for material declaration for the electrical and electronics industry includes the EEE industry DSL, material declaration data exchange requirements and format, material classifications and exemption lists.  The parts of the standard that require periodic updates (such as the lists) are published online on the IEC 62474 database and are updated using an expedited process.

Update to IEC 62474 DSL on January 17, 2022

The IEC 62474 Declarable Substance List (DSL) is a consolidated list of substances that are: (1) relevant to the EEE industry; and (2) either subject to regulations from around the world or of global industry interest for reporting. Manufacturers and suppliers use the DSL in their design and supply chain management to specify and control substances of interest.

The DSL was updated (Version D24.00) to:

  • Add one of the four SVHCs added to the EU REACH Candidate List on January 17 (see Table 1, ID=00181) – the other three SVHCs were screened out during the review.
  • Based on new information, add one SVHC entry that was previously screened out from the DSL (Table 1, ID=00180).
  • Modify entry 00160 (Perfluorooctanoic acid and its salts) to reference Japanese and Korean regulations and add “intentionality added” to the reporting threshold
  • Modify entry 00161 (PFOA-related compounds) to reference the Korean POPs regulation and add “intentionality added” to the reporting threshold
  • Delete entries 00103 and 00104 (PFOA and individual salts and esters of PFOA) that were unique to Norway regulations – the Norwegian PFOA restrictions are now covered by entries 00160 and 00161.

Note: Substances on the DSL are declarable, but not always hazardous or restricted. For example, entries on the DSL include substances and materials that are valuable for recovery such as critical raw materials (CRMs) which are starting to appear in regulations that require reporting to assist in recycling.

Updates to Reference Substance List (RSL)

The newly added Declarable Substance Group “4-Nonylphenol, branched and linear” (ID=00180) has 13 added reference substances as shown in Table 2.

The reference substances for the deleted DSL entries 00103 and 00104 (Perfluorooctanoic acid (PFOA) and individual salts and esters of PFOA) (R00373-R00380) were removed.

Upcoming Material Classification List (MCL) mapping table to SCIP material categories

The IEC 62474 Validation Team will be posting a table that maps the EEE industry Material Classification List (MCL) to the EU SCIP material category list. The SCIP material categories are not always well aligned with material naming conventions used in supply chains and some of the categories overlap making it difficult to select the appropriate category.  The mapping table helps EEE manufacturers identify the material categories for their SCIP declarations based on materials that are commonly used in electrical/electronic products.

The mapping table will be published to coincide with an update to the MCL adding 20 new material classes in the areas of precious metals, thermoplastic resins, duromers and elastomers.

Upcoming update to IEC 62474 Exemption Lists

The IEC 62474 exemption lists corresponding to EU ROHS Annex III and Annex IV are also in the final stages of verification and will soon be published.

Safe Use Instructions for EU SCIP

The IEC 62474 data exchange format has the opportunity to declare safe use instructions (if applicable) for substances in the product. IEC 62474 allows the safe use information to be declared as either a free-text field or as an entry from a reference list published by an authority.

In the Composition Declaration, safe use information may be reported with the Substance or the Material.

In the Declaration for Compliance module, the safe use information may be assigned to either the declaration substance/declarable substance group (DsDsg) or to ArticleInformation if the DSL entry is a REACH Candidate List entry.  However, if the DsDsg entry is a REACH Candidate List entry and the declaration is intended to be used for SCIP submission, then the SafeUse element in ArticleInformation is used for the safe use instructions needed for SCIP.  The reason for using ArticleInformation SafeUse is that the safe use instructions may vary based on the article (for example, whether the SVHC is accessible to the user or not).

Note: ECHA has suggested a possible default statement for safe use instructions in the event that no special instructions are applicable. This has been proposed as “No need to provide safe use information beyond the identification of the Candidate List substance”  If this phrase is updated by ECHA, please use the latest recommendation provided by ECHA.

IEC 62474 DSL updated with PIP (3:1) – April 28, 2021

On April 28, 2021, the IEC 62474 declarable substances list (DSL) was updated to include recent U.S. TSCA restrictions of PIP (3:1) and decaBDE. The restriction of PIP (3:1) is a particular challenge for manufacturers and suppliers given the incredibly short timeframe and that many manufacturers have not been tracking this substance in their supply chain.

Early indication is that PIP (3:1) may be contained in a variety of EEE products and components – wire sheathing and foam gaskets are emerging as examples. However, most manufacturers do not yet know the full extent of the potential applications. These compliance challenges made PIP (3:1) a priority for addition to the IEC 62474 DSL before the next planned update in July.

The updated DSL (version D22.00) includes a new entry for PIP (3:1) (ID=00174) and modifications to the entry for decaBDE (ID=00064) for reporting threshold and regulatory basis.

The latest IEC 62474 DSL may be referenced with the UniqueID authority=IEC62474, identity= IEC62474-DSL, and version=D22.00.

The DSL is available online from the IEC 62474 database at http://std.iec.ch/iec62474 ; the standard itself which specifies the material declaration rules may be purchased in the same manner as any other IEC standard — from the IEC webstore or a reseller.

IEC 62474 Updates to Declarable Substances List (DSL) and Exemption Lists – 2021 January

The IEC 62474 declarable substance list (DSL) and exemption lists were updated on January 19, 2021, coinciding with the update to the EU REACH Candidate List.  IEC 62474, the International Standard for material declaration for the electrical and electronics industry includes the DSL, exemption lists, material classifications, and material declaration data exchange requirements and format.

Update to IEC 62474 DSL on January 19, 2021

The IEC 62474 Declarable Substance List (DSL) is an internationally recognized and consolidated list of substances that are subject to regulations from around the world. Only substances that the Validation Team for IEC 62474 considers as potentially present in electrical and electronic products and systems are included on the DSL. Manufacturers and suppliers use the DSL in their design and supply chain management to specify and control substances of interest.

Note: Substances on the DSL are declarable, but not always hazardous or restricted. For example, entries may be included on the DSL because the substances and materials are valuable for recovery. This includes critical raw materials (CRMs) which are starting to appear in regulations that require reporting to assist in recycling.

The DSL (version D21.00) was updated (see Table 1) to include the two substances added to the REACH Candidate List on January 19 and a new substance group “Halogenated Flame Retardants” that is focused on enclosures of display products such as computer monitors and televisions.

The substance group for halogenated flame retardants was added to address the restriction specified in EU Regulation (EU) 2019/2021 (laying down ecodesign requirements for electronic displays) coming into effect on 1 March 2021. Unfortunately, the restriction in the regulation is poorly specified with no threshold level and no defined list of substances subject to the restriction. The Commission has an amendment underway to provide a threshold level for verification purposes, but there has been no clarification on exactly which substances meet their definition of a flame retardant. The lack of a definitive list could result in differences of opinion between suppliers and downstream manufacturers.

Used for the manufacture of the follow article categories: plastic products, fabrics, textiles, apparel, and leather. Professional application of coatings and inks.

In addition to the newly added DSL entries, two of the existing PFOA related entries (ID=00160 and 00161) had their regulatory basis updated to reflect that they are now restricted under the EU POPs regulation (replacing the REACH Annex XVII restrictions).

Updates to Reference Substance List (RSL)

The newly added SVHC substance group for Dioctyltin dilaurate…  (ID=00173) has three accompanying reference substances as shown in Table 2. Note that entry R00716 uses the CAS name “Stannane, dioctylbis[(1-oxododecyl)oxy]-“ instead of the EC name “Dioctyltin dilaurate” shown on the REACH Candidate List.  They are never-the-less the same substance with the same CAS number.

R00718dioctyltin dilaurate; stannane, dioctyl-, bis(coco acyloxy) derivs.-

For the substance group “Halogenated Flame Retardants”, taking into consideration that there is no substance list in the EU regulation, the references substances were compiled from existing RSL entries that were already identified as halogenated substances with possible flame-retardant properties. Nearly 200 references substances were identified; however, given the lack of clarity on exactly which substances are restricted, the list should be considered indicative and cannot be considered a complete list.

Update to IEC 62474 Exemption Lists

The IEC 62474 database includes exemption lists for EU RoHS Annex III, EU RoHS Annex IV, and China RoHS. The lists are updated with the intention to remain aligned with their respective regulations, but to also include additional information (such as unique identifiers) and strict version control to improve supply chain communication. Adding exemption lists to the IEC 62474 standard has two main purposes:

  1. to provide a globally standardized way of referencing exemptions in material declarations through the supply chain; and
  2. to provide the ability for regulators (who are implementing cloned regulations) to reference an IEC standardized list of exemptions instead of creating and maintaining their own list.

To help clarify and provide guidance on exemptions with conditions or expiry dates that vary by product category, the IEC 62474 exemption lists partition these exemptions into sub-exemptions. Each sub-exemption specifies unique conditions and an expiry date for the product category.

All three exemption lists were updated on January 19, 2021.  The EU RoHS Annex III and Annex IV lists had significant updates to reflect exemptions that expired, transitioned or were newly added by delegated Directives.  The China RoHS exemption list included a minor update to correct the exemption description for exemption 31. All updates may be identified by filtering on a last revised date of 2021-01-19.

SCIP Information in Declaration for Compliance

This article was updated  based on changes made by VT62474 at its January 29-31, 2020 meeting.


This is the fourth in a series of articles on how to use IEC 62474 for collecting supply chain information to meet the upcoming EU SCIP data information requirements.

The Declaration for Compliance is a true/false declaration against each entry in a Declarable Substance List (DSL), indicating whether the declarable substance (DS) or declarable substance group (DSG) is present in the product. This is similar to a Class C declaration in IPC-1752A. The Declaration for Compliance does not include information on product build hierarchy, but it includes sufficient information for the downstream manufacturer to be able to assess compliance against the regulations covered by the DSL.

Given that the Declaration for Compliance is intended to be a simple, product-level declaration, it’s not a natural mechanism to declare information about the articles containing SVHCs.  Never-the-less, Compliance Declarations are preferred by some organizations, so the data exchange format for the Compliance module is being expanded to support information needed for SCIP submissions.

SCIP Information in IEC 62474 Composition Declaration

This is the third in a series of articles on how to use IEC 62474 for collecting supply chain information to meet the emerging EU SCIP data information requirements.

This article was updated  based on adjustments made by VT62474 at its January 29-31, 2020 meeting.

SCIP Reporting in the Composition Declaration

The Composition Declaration is one of two substance declaration modules provided by IEC 62474:2018. It is used by a response (e.g. supplier) to provide a hierarchical declaration of substances within materials and/or product parts that make up the product.  IEC 62474 requires that at least DSL substances that are present in the product be reported in a composition declaration, but it may include other substances, up to and including a full material declaration (FMD).

The declaration of materials and product parts is usually optional, but this becomes mandatory if the material or product part contains a declarable substance based on that material or product part.  For example, if the declarable substance has a threshold based on battery then the battery must be declared as a product part.  This also applies to a (REACH) article that contains an SVHC on the REACH Candidate List.  The first article containing the SVHC must be declared as a product part so that downstream manufacturers can calculate the mass percent of the SVHC in the Article.

Note: Although the standard specifies that material and product parts are usually optional, a requester (e.g. manufacturer or a solution provider) may require that material and/or product part information be provided, even though the standard does not make it mandatory. That is, requester requirements may supplement and enhance the minimum requirements specified in the standard, but this information is subject to mutual agreement between requester and responder.

SCIP Information about Product in IEC 62474

This article was updated  based on changes made by VT62474 at its January 29-31, 2020 meeting.


This post is the second in a series of posts about how to use IEC 62474 to declare information through the supply chain so that an EU SCIP duty holder (manufacturer, importer, or distributor) can meet its submission obligations in the EU SCIP database.

The first article is available at: IEC 62474 Support for EU SCIP Database

A submission into the SCIP database requires that certain minimum information about the product being manufactured or imported into the EU is provided.  This includes the Article name, primary article identifier, article category (i.e. CN customs code), safe use instructions, production in the EU, and number of units.  The “production in the EU” indicator has the possibility of a default response “Unwilling to disclose” and for the top-level product being submitted, the number of units will normally be one.  For the other data fields, the material declaration will need to report this information.

The above data is provided in the ProductID element of the XML Schema as shown in the table below. Continue reading

IEC 62474 Declarable Substance List Updated – January 16, 2020

The IEC 62474 DSL and RSL were updated on January 16, 2020 to version D19.00. The update included edits to a few existing DSL entries and the addition of two new entries corresponding to two of the four substances (relevant to EEE) that ECHA added to the REACH Candidate List substances on same day.

Changes to Existing DSL Entries

  • The previous declarable substance group “Disodium tetraborates” was modified to “Disodium tetraborate, anhydrous” to align with the REACH Candidate List designation by separating out “Tetraboron disodium heptaoxide, hydrate” as a new declarable substance entry (ID=00163)
  • Notes were added to DSL entries 00138, 00144, 00145, and 00148 to indicate that these substances are polycyclic aromatic hydrocarbon (PAH)
  • A note was added to entry 00046 (Polychlorinated Biphenyls (PCBs) and specific substitutes” to clarify that an EU REACH Regulation Annex XVII entry applies to one or more reference substances in this Declarable Substance Group.
  • Updates that had been made by ECHA to CAS numbers were also made to DSL entries: 00144, 00145, 00157, 00159.

New Entries

  • Two of the four SVHCs that were added to the REACH Candidate List by ECHA on January 16, 2020 were added to the DSL: “Perfluorobutane sulfonic acid (PFBS) and its salts” and “Diisohexyl phthalate”. The other two Candidate List entries were screened and are not added. Four reference substances were added to the RSL for PFBS.

Additional Information

The updated DSL version is D19.00. The new and modified entries have a last revised date of 2020-01-16.

If anyone is aware of errors or omissions in the database (e.g. a regulated substance that is not included in the DSL but has potential EEE applications) or a regulatory reference that is out of date, please send an email to ECD Compliance and we will raise the issue with the IEC 62474 validation team.

Revised IEC 62474:2018 Flexibility for Material Declarations

The IEC 62474:2018 standard introduces several new and revised capabilities to the International Material Declaration Standard. The new capabilities based on emerging regulatory requirements, user feedback, and the needs of a broad range of industries. It provides significant flexibility for suppliers to provide material declaration information while ensuring that critical information for downstream manufacturers to assess product compliance is always available. The Data Exchange Format now includes a new Declaration for Compliance module and additional support for EU REACH compliance and the upcoming EU Substance of Concern in Products (SCIP) database.  The changes were also intended to make the standard useful to a broad range of industries and different stages in the supply chain given the intertwined nature of global supply chains. .

The material and substance information in the material declaration are organized into declaration modules referred to as “sectionals”.   A hierarchical data representation of the “Product” type in the XML schema was shown in Figure 2. The declaration modules (types of declarations) that may be included in the IEC 62474 material declaration are:

  • Declaration for Compliance;
  • Composition Declaration;
  • Material Class Declaration;
  • Query Statement Declarations (represented by QueryList)

A material declaration that conforms to IEC 62474:2018 needs to include at least a Declaration for Compliance or a Composition Declaration (it may also contain both).

The Composition Declaration is used by a responder (supplier) to provide a hierarchical declaration of substances within materials and/or product parts that make up the product.  IEC 62474 requires that at least DSL substances that are present in the product be reported in a composition declaration, but it may include other substances, up to and including a full material declaration (FMD).  Some of the declaration features in the Composition Declaration (most of which are optional) include:

  • The capability for the supplier to provide information about product parts in the build hierarchy and materials (optional). An indefinite hierarchy of product parts is allowed by the Composition Declaration (i.e. product parts may be further partitioned into product parts);
  • Declaration of a DSL that indicates the minimum set of declarable substances that have been declared if they are present in the product;
  • True/False flags enabling the responder to indicate if the Composition Declarations is a full material declaration (FMD) and/or if it includes required information for SCIP submission;
  • Information about the materials in the product including: material class (or material category), material properties and use descriptions
  • The ability to identify substances based on a variety of different conventions, including DSL entry, CAS registry number, EC number, REACH Candidate List entry, etc. If the substance is part of a declarable substance group, it’s also possibly to ‘tag’ the substance with a substance group ID – this assist the downstream manufacturers with compliance assessment;
  • Applicable exemptions to substance restrictions that are needed by downstream manufacturers in assessing compliance

The Declaration for Compliance is a simplified true/false declaration against each entry in a Declarable Substance List (DSL), indicating whether the declarable substance (DS) or declarable substance group (DSG) is present in the product. The Declaration for Compliance typically does not include information on product build hierarchy (see exception below), but it includes sufficient information for the downstream manufacturer to be able to assess compliance against the regulations covered by the DSL.

An exception to including build hierarchy information in the Declaration for Compliance is when the declaration provides information needed for an EU SCIP database submission.  In the SCIP use case, information about the lowest-level (first) Articles containing the REACH Candidate List SVHCs are needed. This use case will be described in future blog posts once the functionality has been finalized and published by the IEC 62474 Validation Team.

If the material declaration is intended to cover multiple DSLs, then multiple instances of ‘Compliance’ may be declared – one for each DSL. The Compliance declaration module also includes a flag to indicate if the sufficient information has been provided for a

A material declaration that conforms to IEC 62474:2018 needs to include at least a Declaration for Compliance or a Composition Declaration but it may also include both.

Material Names

If one or more materials are declared in the material declaration, a name for the material is mandatory and a Identifier (MaterialID) of the material is optional. This material name is the name or other text identifier of the material within the product. Material name may describe the material and/or describe the use or location of the materials in the part. The MaterialID field in material can be used to identify a declared material based on specifications defined in a standard (e.g., ISO 1043, parts 1 through 4 for plastics).

When declaring a material in the declaration, the material class to which the material belongs should be reported in the “materialClassID” field. This is recommended by subclause 4.5.3(e) in the standard.
