About Moses Lake Industries

Moses Lake Industries was established in 1984 as a wholly- owned subsidiary of Tama Chemicals. With an unparalleled commitment to customers and focus on innovation, we have grown to be a leading global supplier of high-performance chemical solutions to the semiconductor and flat panel industries.

Mission, Vision, and Values


We develop and manufacture high-quality, leading-edge chemistries, while providing superior customer service and strengthening our team and communities for future generations. 


MLI’s commitment to Innovative, Operational, and Financial Excellence are critical to meeting our mission.

Innovative Excellence – MLI was started 35 years ago based on a single product. Through our commitment to innovation, understanding of the market, and listening to our customers, we have grown our portfolio to over 1,000 products. We believe our focus on innovation is why our customers choose to partner with MLI. 

Operational Excellence – MLI has grown our operational capabilities to keep pace with our innovative growth. We have developed a quality operating system that has led to a continuously improving production process. We believe that our in-house operational capabilities are the reason we are able to meet the evolving expectations of our customers.

Financial Excellence – MLI has become a very complex business with plants around the world. We work very hard to understand the cost to source raw materials, produce world-class products, and deliver. We believe that our focus on understanding and reducing our costs is the reason we can offer world-class products at cost-competitive prices. 

MLI Core Values

These values have led to our success over the past 35 years and will be a critical part of our success going forward.

  • Safety
  • Integrity
  • Collaboration
  • Ownership
  • Service
  • Sustainability 


At MLI, we are committed to creating sustainable opportunities for our employees and a sustainable world for this and future generations. It’s not only the right thing to do; it’s critical to the long- term health and financial strength of our business and the communities we operate in. Every year we evaluate the social, environmental and economic impact of our business and set new goals.

MLI supports the efforts and Code of Conduct of the Responsible Business Alliance (RBA) which promotes social, envionmental and ethical industry standards. 

This includes responsible sourcing of minerals so as not to directly or indirectly finance or benefit armed groups that are perpetrators of serious human rights abuses in the Democratic Republic of the Congo or an adjoining country. MLI exercises due diligence with the selection and monitoring of our direct supply chain to avoid procurement of these Conflict Metals.

Please note that due diligence only provides reasonable – not absolute – guarantees about the origin of the conflict minerals in our products. MLI depends on supply chain information provided by our direct suppliers in assessing the source of such minerals, the veracity of which can be difficult to ascertain.

We are committed to providing a safe, secure and healthy workplace for our employees, contractors, visitors and the communities in which we operate.


MLI is also committed to respecting human rights in our operations, our supply chain, our business partnerships and our products. We believe child labor, forced labor, or human trafficking in any form—including slave labor, prison labor, indentured servitude, or bonded labor are unacceptable.

A Comprehensive, Integrated Approach

Every individual at MLI is responsible for quality and continuous improvement; everyone is empowered to identify risks, concerns and issues effecting quality and safety. Systematic training and recertification of our staff ensure consistent awareness of MLI’s Quality Operating System, and compliance with procedures and requirements. 

Our Quality Management System provides a consistent and coordinated approach to ensure and improve quality through every step of development, manufacturing, delivery and customer support. 

Communication and close interaction with our customers is key to identifying needs and developing solutions that will meet and exceed expectations.  We build strong relationships with our customers by listening, working collaboratively and acting as partners in innovation. 

Issue prevention via Failure Mode and Effects Analysis (FMEA) is an integral part of our product and process design and has informed and continues to shape our Quality Management System:

  • Raw Material Sourcing – To ensure the highest quality and consistency, we manufacture as much of our  our own raw material as possible.  Raw material not produced in-house undergoes rigorous acceptance testing prior to use.
  • Manufacturing Systems Control– Our in-house experts design, build and manage our infrastructure and manufacturing systems.  This level of control allows us to ensure the highest quality and consistency through multiple facilities.  It also facilitates quick response to the evolving needs of our customers.
  • Analysis and Monitoring – Advanced analytical devices provide continuous real time monitoring and analysis of production, allowing for immediate in-line corrective response.  Solicitation of customer feedback as well regular internal audits and self-assessment of processes support continuous improvement. 
  • Packaging – We maintain strict packaging specifications, cleaning methodologies and filling preparation procedures to eliminate sources of contamination.  A Certificate of Analysis, with complete analytical results, is provided with each product shipment.
  • Delivery – Warehouse and shipping conditions and procedures are rigorously controlled to ensure products are consistently received on time, damage-free and within temperature specification. 
  • Customer Support –  Quality and consistency is critical in our products, and crucial in our personal interactions, as well.  Our management team, scientists, sales staff and accounting and billing department aim to provide unsurpassed responsiveness and customer service.
