MKS has adopted the industry standard Responsible Business Alliance ("RBA") Code of Conduct as its Supplier Code of Conduct. The Supplier Code of Conduct provides standards and guidelines of conduct for all suppliers doing business with any MKS company worldwide. Our reputation is built on honesty, integrity, quality and trust. We therefore expect our supply chain partners to conduct themselves in the same manner, regardless of local business practices or social customs. The Supplier Code of Conduct sets out the minimum standard of business behavior expected so that suppliers act in ways that are ethical, corporately responsible and ensure compliance with applicable laws and regulations.

• MKS Statement on RBA Code of Conduct
• RBA Supplier Code of Conduct

MKS Inc. relies on a broad, multi-tier supplier network to deliver material, components and sub-systems to our wide range of finished products. We work for full transparency with our direct suppliers to provide required declarations and disclosures relative to sourced materials. We also expect our suppliers to pass this requirement on to their suppliers as well. This is specifically emphasized for Conflict Materials as defined under Section 1502 of the 2010 Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Conflict Minerals Rule”). These materials are a subset of the larger group of Critical Materials defined by the National Research Council.

Several of the elements identified in the Critical Materials list are used in foundational electronic components, as well as in specialty metal formulations. Additionally, trace amounts of the rare earth elements are used in components that serve our Light & Motion product families. However, we do not currently see significant risk to our overall operations due to the use of these materials. For those materials that carry some risk, or risk that changes as a result of our ongoing monitoring or new product introductions, we apply necessary risk mitigation steps, including but not limited to – securing safety stock at multiple levels in the supply chain, securing second sources of impacted parts or materials, hedging for price protection, etc. We conduct annual sourcing reviews to regularly assess the overall health and resiliency of our global supply base.
