Hocking International Laboratories



About Us

Privately owned and based in San Marcos, CA, Hocking International has a long history of helping customers grow with unique private label products.

It all started in a California garage. Operating then as “California Chemical”, Ed and Sherry Hocking produced chemicals used in the commercial fishing industry. Ten years later they expanded into a new manufacturing facility, as well as into new markets. Their son, Doug, who served at the company helm into 2020, continued the company's expansion across industries and led physical expansion of the company into three modern, high-capacity manufacturing plants.

Today Hocking is one of the leading custom chemical manufacturers in the world. We proudly serve customers in the Agriculture, Turf & Ornamental, and Industrial industries. We have built a team of exceptionally talented professionals, and aim to continue our growth by providing outstanding service and quality.
