Supplier Code of Conduct Reporting

MKS suppliers may report any violations or suspected violations of the MKS Supplier Code of Conduct through a MKS Supply Chain Manager or the MKS Compliance Hotline:

• Online: mksinst.ethicspoint.com  
• Mobile: mksinstmobile.ethicspoint.com  
• Phone: 855-874-1532
  Dialing instructions (including local access codes) when calling from outside of the U.S. are available at mksinst.ethicspoint.com  . Select your country to view dialing instructions.
  

While we strongly encourage you to identify yourself when reporting violations so that we may follow up with you, as necessary, for additional information and may adequately investigate and address the matter, you may report violations anonymously if you wish (unless anonymous reports are contrary to local law). We may be prevented from investigating and/or addressing matters raised in reports made anonymously, if contrary to the local laws of a particular country.
