IEC 62474 Declarable Substance List (DSL) – July 2018 Update

The IEC 62474 Declarable Substance List (DSL) was updated to Version D16.00 on July 8, 2018. The update includes relevant SVHCs from the recent update to the EU REACH Candidate List and a few other changes to declarable substance and reference substance entries as described below.

Declarable Substance List (DSL)
Eight of the ten SVHCs added to the REACH Candidate List on June 27th were included in the DSL based on their potential presence in EEE products. The substance review for possible EEE uses was conducted by the IEC 62474 Validation Team (VT62474) with experts from Asia, Americas, and Europe. Note: if anyone is aware of information that may be relevant to whether or not one of the substances may be present in EEE products, please forward the information to the VT (by sending an email to iec62474(at)rohs.ca).

One of the additions, the phthalate DCHP, had been proposed for the Candidate List in 2016, but the Member State Committee (MSC) representing the EU countries couldn’t agree as to whether or not it met the requirements for listing. The substance was referred to the European Commission who made the final decision and issued Commission Implementing Decision (EU) 2018/636 in April to add the substance.

The additions to the DSL are listed in Table below.

One entry was deleted from the DSL. The restriction of BNST (Benzenamine, N-phenyl-, reaction products with styrene and 2,4,4-trimethylpentene) was repealed by Canada and the DSL entry (ID=00127) was accordingly deleted from the DSL.

ID	Specific Substance	CAS number	Common Synonyms	Typical Applications	Reportable Applications	Reporting Threshold
00148	Benzo[ghi]perylene	191-24-2		Impurities in carbon black, which is used as coloring agent in plastics and softener in rubbers	All	0.1 mass% of article
00149	Octamethylcyclotetrasiloxane	556-67-2	D4	Siloxanes are monomers used to manufacture silicones. They may remain as unreacted in silicone polymers and copolymers, used in many electrotechnical equipment product categories.	All	0.1 mass% of article
00150	Decamethylcyclopentasiloxane	541-02-6	D5	Siloxanes are monomers used to manufacture silicones. Residuals may remain in silicone polymers and copolymers.	All	0.1 mass% of article
00151	Dodecamethylcyclohexasiloxane	540-97-6	D6	Siloxanes are monomers used to manufacture silicones. They may remain as unreacted in silicone polymers and copolymers, used in many electrotechnical equipment product categories.	All	0.1 mass% of article
00152	Disodium octaborate	12008-41-2		Wooden veneer sheets and pressed wooden panels (as a constituent within the starch adhesive), as a flame retardant, as stabilizer in aminoplastic resins, and as a biocide in professional and industrial wood preservation.	All	0.1 mass% of article

00139	Dicyclohexyl phthalate	84-61-7	DCHP	Plasticizer, dye, pigment, paint, ink, manufacture of adhesive, lubricant	All	0.1 mass% of article

Reference Substance List (RSL)
Nine reference substances were deleted from the Reference Substance List (RSL). The substances are SVHCs that are on the REACH Candidate List; however, they have been previously screened out because no applications were found whereby the substances would remain in EEE products at or above the reporting threshold level. To avoid confusion that can arise when a regulated substance is on the RSL but not on the DSL, the VT 62474 agreed to remove the substances from the RSL for consistency.

One other RSL entry was modified. The RSL entry R00147 (substance name “Hexabromocyclododecane (HBCDD)”) was modified to remove the CAS registry number “3194-55-6”. In January 2018, a new entry (R00492) was added to the RSL with the specific substance represented by this CAS number (1,2,5,6,9,10-hexabromocyclodecane), so listing the CAS number against the generic substance entry was no longer needed. To avoid confusion from having the same CAS number listed in two different RSL entries for the same substance group, the CAS number was removed from the generic entry.

Additions and modifications to the Reference Substance List (RSL) are shown in the Table below.

Type of Change	ID	Substance Group	Specific Substance	CAS number
Deleted	R00099	Cadmium/Cadmium compounds	Cadmium chloride	10108-64-2
Deleted	R00100	Cadmium/Cadmium compounds	Cadmium sulfate	10124-36-4, 31119-53-6

Modification	R00147	Hexabromocyclododecane (HBCDD)	Hexabromocyclododecane (HBCDD)	25637-99-4

Material Class List (MCL)
No changes were made to the MCL during this update to the IEC 62474 database. However, a major revision to the Material Class List is currently underway — the changes will better support Life Cycle Assessment (LCA) of EEE products.

Upcoming Major Changes to the IEC 62474 Standard and Database
The IEC 62474 standard was due for its periodic review and revision a couple years ago (like any other IEC standard) and the IEC/TC111 Maintenance Team has been working hard to improve the standard based on feedback we’ve received from many users and other stakeholders.

The FDIS version (Final Draft International Standard) of the revised standard was completed in March and is currently in translation; it should be available for voting at the end of July (voting is by country). In the interim, the VT62474 is busy drafting the changes to the XML schema to meet the new requirements and compiling other information that will be added to the database such as new data fields for the DSL and exemption lists. We will be posting additional information on this site over the next few months.

For immediate guidance, ECD Compliance supports manufacturers, solution providers, and suppliers on the implementation of IEC 62474. We can work with you on the transition to the new requirements and provide implementation guidance. For additional information, contact ECD Compliance.

The IEC 62474 Database
The IEC 62474 DSL is available on the IEC 62474 database at: http://std.iec.ch/iec62474. The new and modified entries have a last revised date of 2018-07-08.

IEC 62474 Declarable Substance List – Jan 2017 Update

The IEC 62474 Declarable Substance List (DSL) was updated on January 12, 2017 following the European Chemical Agency (ECHA) addition of substances to the EU REACH Candidate List on the same day. The update includes those of newly added REACH SVHCs that may be constituents of EEE products. A few additional maintenance updates were also made.

The DSL is used globally by EEE manufacturers, suppliers, and IT solution providers as a common list of substances that should be declared throughout the supply chain, allowing downstream manufacturers to access product compliance to substance regulations around the world. The DSL includes declarable substances and substance groups together with reporting thresholds and reportable applications.

The update includes:

two of the four SVHCs added to the EU REACH Candidate List on January 12, 2017
reference substances for one of the SVHCs that is a group of substances
an update to the reportable application field of one of the Lead/Lead compound substance groups
deletion of two reference substances

The IEC 62474 data exchange format (XML schema and developer’s table) was not updated during this maintenance cycle. There were no changes made to the Material Classes.

Declarable Substance List (DSL)

Additions and modifications to the DSL are listed in the table below

ID	Substance Group	Specific Substance	CAS number	Reportable Applications	Reporting Threshold
00141		4,4’-isopropylidenediphenol (BPA, Bisphenol A)	80-05-7	All	Intentionally added or 0.1 mass% of article
00142	Nonadecafluorodecanoic acid (PFDA) and its sodium and ammonium salts	See Reference Substances	See Reference Substances	All	0.1 mass% of article
00021	Lead/Lead Compounds	See Reference Substances	See Reference Substances	All, except for: 1. batteries, 2. surface coating material of cables/cords with thermoset or thermoplastic coatings, and 3. paint and similar surface coatings of toys and other articles intended for use by children	0.1 mass% of total Pb in homogenous material

Bisphenol A (BPA) was added to the REACH Candidate List and, given that the substance has several applications in EEE manufacturing, was included in the IEC 62474 DSL.

For the Lead/Lead Compounds entry with ID=00021 a clarification was made to the reportable application field. There are a total of five different Lead/Lead Compound entries with different reporting thresholds for different reportable applications. The clarification helps ensure that the correct threshold is being applied for each application.

Background

The IEC 62474 DSL is an internationally recognized and harmonized list of substances and substance groups that are regulated and may be constituents of electrical and electronic products and systems. Electrical and electronic manufacturers and suppliers use the DSL in their design and supply chain management operations to specify and control substances of concern. The list is typically updated as needed based on regulatory changes. For additional information about IEC 62474, see the article About IEC 62474. The IEC 62474 database is available online; the standard itself which specifies the material declaration requirements and rules may be purchased in the same manner as any other IEC standard — from the IEC webstore or a reseller.

Additional Information

The updated DSL version is D13.00. The new and modified entries have a last revised date of 2017-01-12.

If anyone is aware of errors or omissions in the database (e.g. a regulated substances 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.

Update to IEC 62474 Declarable Substance List is Released – April 8, 2015

The latest update to the IEC 62474 Declarable Substance List (DSL) and data exchange format was released on April 8, 2015. The DSL is revised to version D8.00 and the updated data exchange format (XML schema and developer’s table) are now version X6.00.

The DSL is an internationally recognized and harmonized list of substances and substance groups that are regulated and may be constituents of electrical and electronic products and systems. Major electrical and electronic manufacturers and suppliers use the DSL in their design and supply chain management operations to specify and control substances of concern. The list is typically updated twice a year.

Additions to the Declarable Substance List (DSL)

Regulatory changes drove five additions and modifications to the DSL, namely for the substance entries:

Benzenamine, N-phenyl-, reaction products with styrene and 2,4,4-trimethylpentene (BNST)
2-ethylhexyl 10-ethyl-4,4-dioctyl-7-oxo-8-oxa-3,5-dithia-4-stannatetradecanoate (DOTE)
reaction mass of 2-ethylhexyl 10-ethyl-4,4-dioctyl-7-oxo-8-oxa-3,5-dithia-4-stannatetradecanoate and 2-ethylhexyl 10-ethyl-4-[[2-[(2-ethylhexyl)oxy]-2-oxoethyl]thio]-4-octyl-7-oxo-8-oxa-3,5-dithia-4-stannatetradecanoate (reaction mass of DOTE and MOTE)
2-(2H-benzotriazol-2-yl)-4,6-ditertpentylphenol (UV-328)
2-benzotriazol-2-yl-4,6-di-tert-butylphenol (UV-320)

Four of the six SVHCs added to the REACH Candidate List in December 2014, have the potential to be final constituents of EEE above the reporting threshold and, therefore, passed the IEC 62474 screening process and were included. The UV-320 substance was already on the DSL based on another regulation, but its reporting threshold has now been updated to include the REACH SVHC threshold. For the other two SVHCs, no evidence was found that they occur in EEE and were therefore not added. If anyone is aware of these substances being used in EEE, please contact the IEC 62474 validation team by sending an email to iec62474(at)rohs.ca.

BNST is restricted in Canada under the Prohibition of Certain Toxic Substances Regulations, 2012 and has been used as an additive to lubricants to improve performance and reliability in several types of electric motors. The regulations provided an exemption for BNST in lubricants until March 2015 and thereafter only by permit. As the global supply chain gains awareness of the restriction, applications of BNST lubricants have been turning up in a variety of applications from IT equipment, to HVAC equipment and starter motors and alternators.

The new and modified entries in the DSL due to new substance regulations are listed in Table 1 below.

Table 1: DSL Changes Due to New Regulations (MC-2014-02)

Specific Substance	CAS number	Typical Applications	Reportable Applications	Reporting Threshold	Basis
Benzenamine, N-phenyl-, reaction products with styrene and 2,4,4-trimethylpentene	68921-45-9	Lubricant additive in motors and sliding mechanisms	All	Intentionally added	Canadian Regulation
2-ethylhexyl 10-ethyl-4,4-dioctyl-7-oxo-8-oxa-3,5-dithia-4-stannatetradecanoate (DOTE)	15571-58-1	PVC stabilizer	All	0.1 mass%	REACH Candidate List
reaction mass of 2-ethylhexyl 10-ethyl-4,4-dioctyl-7-oxo-8-oxa-3,5-dithia-4-stannatetradecanoate and 2-ethylhexyl 10-ethyl-4-[[2-[(2-ethylhexyl)oxy]-2-oxoethyl]thio]-4-octyl-7-oxo-8-oxa-3,5-dithia-4-stannatetradecanoate (reaction mass of DOTE and MOTE)		PVC stabilizer	All	0.1 mass%	REACH Candidate List
2-(2H-benzotriazol-2-yl)-4,6-ditertpentylphenol (UV-328)	25973-55-1	UV stabilizer	All	0.1 mass%	REACH Candidate List
2-benzotriazol-2-yl-4,6-di-tert-butylphenol (UV-320)	3846-71-7	UV-stabilizer in adhesives, paints, printing inks, plastics, inked ribbons, putty, caulking or sealing fillers	All	Intentionally added or 0.1 mass%	REACH Candidate List

Cleanup of Declarable Substance List

In 2014, the IEC 62474 Validation Team (VT) launched a major review and cleanup of the substance names and substance group names in the current DSL and reference substance list (RSL). For example, in some cases, regulators have revised the spelling of a substance name, and in other cases alternate spellings may have been introduced by regulations in different countries. Nearly 30 current substance and substance group entries were identified and approved for revision.

As part of the DSL review, the VT also considered how to deal with substance names that are listed by regulators but are not chemically accurate or that include a description or synonym in the substance name. For example, the European Chemical Agency (ECHA) is notorious for including a description of the substance in the substance name rather than providing a separate description field. It’s important for the industry to have substance naming information that is meaningful to the upstream global supply base who may be several levels removed from importing products into the final destination country.

The Declarable Substance Group and Declarable Substance entries that were modified are listed in Table 2 at the end of this article.

For two of the substance entries (Dibutyltin dichloride (DBTC) and Cadmium sulphide), the substance group that was previously listed in the substance group was deleted. Declarable Substance groups have not be consistently listed for declarable substances in the IEC 62474 DSL and given that regulations sometimes create overlapping substance groups, the VT has agreed to not prescribe a substance group for declarable substance entries. This provides users with more flexiblity in constructing the material declaration file and will reduce confusion when there there is more than one applicable substance group.

Changes to the Reference Substance List (RSL)

The DSL cleanup also impacted a few of the entries in the Reference Substance List (RSL).

The substance group name for “Hexabromocyclododecane (HBCDD) and all major diastereoisomers” was expanded to “Hexabromocyclododecane (HBCDD) and all major diastereoisomers identified: Alpha-hexabromocyclododecane Beta-hexabromocyclododecane Gamma-hexabromocyclododecane” to align with the REACH Candidate List;
The declarable substance group name “Shortchain Chlorinated Paraffins (C10 – C13)” was renamed to “Alkanes, C10-13, chloro (Short Chain Chlorinated Paraffins)” to better align with he current naming convention that is used internationally;
The declarable substance group “Refractory Ceramic Fibres (RCF), Aluminosilicate” has been deleted (it is no longer referenced by the DSL);
The declarable substance group “Boric Acid” has been deleted (it is no longer referenced by the DSL);
Reference substances have been added for “Hexahydromethylphthalic anhydride”. The four reference substances provide a complete list of substances that are applicable to the substance group as specified in the regulation.

Material Classes

There were no changes to the Material Classes.

Data Exchange Format (Developer’s Table and XML Schema)

The IEC 62474 Developer’s Table has been updated with three minor changes

The reporting obligation for Mass and MassPercent elements in the MaterialClass Class were updated to allow only one of Mass or MassPercent to be provided for MaterialClass , but not both. Similar changes were made to the Part, Material, SubstanceGroup, and Substance classes during the last update cycle. This change makes MaterialClass consistent with the other data elements;
The note associated with the reportableApplication (ACB123) was corrected. The note had previously suggested that reportable applications should be concatenated when multiple reportable applications are simultaneously triggered. For example, this can happen for declarable substance groups such as “lead/lead compounds” which have multiple entries in the DSL with different reportable applications and reporting thresholds. However, since the “Threshold” Class (ACA021) was created, multiple thresholds can now be reported by using multiple Threshold elements; concatenating reportable applications is no longer relevant (nor allowed) .
The definition of the MassPercent and Mass elements in “Material” (ACB048, ACB049) was modified to clarify that they refer to the mass of the material.

The XML Schema and developer’s table are now version X6.00. Changes in the X6.00 developer’s table compared to X5.00 version are shown in red font. There were no changes to the XML Schema in this update. The X6.00 schema is identifical to the X5.00 schema.

Further Information

The declarable substance list (DSL) is available for download at http://std.iec.ch/iec62474. Entries that are new or revised may be identified by a LastRevised date of 2015-04-08 for the DSL and the developer’s table.
