ST is committed to complying with legislation and aligning with customer requirements relating to conflict minerals. We take careful measures to avoid procuring 3TG metals that are directly or indirectly associated with human rights violations or environmental damage in the Democratic Republic of Congo and its neighboring countries.    

ST began to address the conflict minerals issue in 2007 by requiring our tantalum suppliers to confirm they were not sourcing metals from conflict areas.  We now participate in the Electronic Industry Citizenship Coalition (EICC) and Global e-Sustainability Initiative (GeSI) programs and require all our suppliers and subcontractors to provide evidence that they are not sourcing 3TG metals (Tantalum, Tungsten, Tin and Gold) through any channels that fund armed groups in the eastern provinces of Democratic Republic of the Congo (DRC) and surrounding regions. Detailed information about our supply chain sources and validation are disclosed to our customers on request via their sales representative.

"Conflict minerals is a complex issue in itself. It is even more intricate in the electronics industry, which has a complicated supply chain involving several hundred suppliers. For the last five years, we have been collaborating with industry leading companies through the EICC and we are also working closely with several of our main customers to reach an even higher level of supply chain transparency."

Assurance of conflict-free minerals

ST manages conflict minerals in accordance with the following legislation and best practices:


We have developed a comprehensive process to provide our customers with evidence to demonstrate that our products only contain conflict-free minerals: 

  • ST requires suppliers to:
    • Sign a written commitment annually stating that no metals used in ST products originate from the identified conflict zones;
    • Have a DRC Conflict-free Minerals Policy;
    • Conduct a thorough supply chain analysis to identify and provide ST with the names of smelters and refiners involved in mineral processing; 
    • Disclose the country of origin and the mining location of procured minerals;
    • Implement due diligence to verify suppliers’ compliance with its Conflict-free Mineral Policy;
    • Source 3TG metals from smelters who themselves have been validated as using DRC conflict-free minerals by a third party certified organization.
  • A supplier’s ability to meet these requirements is then reviewed, and if any of them are not met we ask the supplier to provide us with evidence that corrective action plans have been implemented.
  • Collected information is aggregated and shared with customers when requested.
  • Any identified smelters are contacted by both ST and the supplier to invite them to join the Conflict Free Smelter (CFS) program. In fact smelters’ engagement rate with the CFS engagement is one of our internal key performance indicators. If suppliers provide other evidence of being conflict-free, we conduct a risk assessment to evaluate whether the information received is sufficient to meet our requirements.
