KOST USA has served as a trusted business partner to its customers, providing premium quality products and unparalleled customer service.

Established in 1985, KOST was founded on the premise that everyone within the company makes a difference – every employee understands the company’s Mission, Vision, and how their roles individually affect the total organization’s objectives and our customers’ satisfaction.

Our team works collaboratively and is accountable for fulfilling this brand promise.

At KOST USA, we recognize and seek out opportunities, take appropriate risks, and make decisions that mutually benefit our employees, our customers, and our suppliers. This is accomplished as we make certain that our work is aligned with our company’s capabilities and our Mission. We continue to consistently deliver on our promise every single day.

We are trusted, entrepreneurial partners with our customers, creating joint growth by providing preferred liquid technologies and passionate service.

We are an agile company with the ability to find and exploit profitable extensions to our core businesses and technical heritage. We focus on mature markets where major corporations are not meeting customers’ needs.

We are successful because we provide unique products and services that our competition is unable to match.
