IEC 62474 Declarable Substance List is Updated (June 2016)

The IEC 62474 Declarable Substance List (DSL) and the Reference Substance List (RSL) were updated on June 22, 2016. The substance lists are used globally by EEE manufacturers, suppliers, and IT solution providers as a common list of substances and substance groups that are declared throughout the supply chain. Downstream manufacturers of EEE products need suppliers to declare these substances when they are present in order to determine compliance to substance regulations around the world and as evidence of due diligence in their conformity assessment.

The update includes:

  • the one substance added to the EU REACH Candidate List on June 20, 2016
  • The entry for “Perfluorononan-1-oic-acid and its sodium and ammonium salts” was changed from a substance entry to a substance group and the three substances in this group were added as reference substanc.

The IEC 62474 data exchange format (XML schema and developer’s table) was not updated during this maintenance cycle.


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 (free of charge); 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.

Additions to the Declarable Substance List (DSL)

Additions and technical modifications to the DSL were driven by EU REACH. The new/modified entries are listed in the table below

EU REACH Candidate List

Only one substance was added to the REACH Candidate List by the European Chemical Agency (ECHA) on June 20, 2016. The subtance has potential applications in EEE and is therefore included in the DSL.

The substance “Perfluorononan-1-oic-acid and its sodium and ammonium salts” had been added to the DSL in December 2015 as a substance.  However, it’s actually a set of three substances; therefore it’s listing has been changed to a substance group and the three individual substances have been added to the reference substance list.

The new reference substance entries just added are shown in the table below.
