Material Declaration

STMicroelectronics’ banned, exempted and declarable substances list is regularly reviewed to include applicable regulations and customer's requirements and to insure that our suppliers are in line with our rules regarding the use of chemicals and hazardous substances. It defines STMicroelectronics declarable substances that our suppliers and subcontractors have to report in addition to regulated substances declarations.

STMicroelectronics has adopted the IPC1752 as the standard for the reporting of declarable substances and material groups. Our overall objective is to provide our customers with full product material chemical composition based on IPC-1752-2 Class 6 or IPC1752A, including:

  • Product information (including product Raw Line code for specific product materials declarations).

  • Manufacturing Process reporting application ( Terminal base alloy, Moisture sensitivity, Reflow cycles...)


  • Detailed materials chemical content of our products
    - List of substances by homogeneous material international reference
    - Homogeneous material weight (gram and ppm)
    - JIG declaration


  • RoHS declaration and exemptions

  • REACH SVHC declaration
