Wilmington, California Operations

Supporting supply chain reliability

Our Wilmington facility at the Port of Los Angeles has been in continuous operation since 1924. Today it manufactures products used for agriculture, wood preservation, and flame and smoke retardant applications.

The refinery and shipping operation produces and ships more than 36,000 tons of packaged goods and more than 300,000 tons of bulk material to customers in Europe, Malaysia, and China. Borates are shipped by rail to the Wilmington facility. The cargo is then loaded onto bulk vessels for shipment. At their destinations, the borates are unloaded, inspected, packed, and distributed via rail, barge, vessel, or truck.

Education and basic needs

A favorite organization for employees represented by International Longshore and Warehouse Union Local 20 is The Boys & Girls Clubs near our Wilmington site. Each year, employee volunteers stuff 300 backpacks with age-appropriate school supplies during the annual back pack drive. We have also supported them in their efforts to provide meals, foodstuffs, and distance learning support to families during COVID-19.
