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

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.

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.
