IEC 62474 - Materials declaration update September 25, 2013An update to the international IEC 62474 declarable substances list was released on September 25, 2013.

IEC 62474 provides the electrical and electronics industry with a Internationally accepted list of substances that should be declared by each member of the global supply chain to downstream manufacturers. The declarable substance list (DSL) is available for free download at http://std.iec.ch/iec62474.

There were several additions and modifications to the Declarable substance groups and declarable substances and the reference substances. Additions included the substance group Hexahydromethylphthalic anhydride and six Substances of Very High Concern (SVHCs) that were added to the REACH SVHC Candidate List in June 2013 - Cadmium, Cadmium oxide, Dipentyl phthalate (DPP), Pentadecafluorooctanoic Acid (PFOA), Ammonium pentadecafluorooctanoate (APFO), and the substance group 4-Nonylphenol, branched and linear, ethoxylated.

There were also modifications made to the substance groups Dibutyltin (DBT) compounds,
Dioctyltin (DOT) compounds, and Tri-substituted organostannic compounds to clarify that the Reporting Threshold is based on mass percent of tin in the part as required by the regulation.

Minor modifications to remove unnecessary spaces and formatting characters were deleted from two entries:

  • substance name Dibutyltin dichloride (DBTC)
  • substance name Silicic acid (H2Si2O5), barium salt (1:1), lead-doped


  • The revised substance/material lists are version D5.00
  • There were no declarable substances or substance groups deleted from the DSL in the revision from D4.00 to D5.00.
  • No changes were made to the material classes in revision D5.00

Reference substances were added for:

  • 4-Nonylphenol, branched and linear, ethoxylated
