UNSPSC 31162818: Anti corrosion anode

An electrically charged device used in corrosion control systems to prevent corrosion of underground or underwater steel structures.

UNSPSC 31162818 Anti corrosion anode is a Commodity code that covers cathodic protection system components—primarily anodes, rectifiers, test equipment, and related hardware—used by state and local water utilities, transportation authorities, and facility management departments to protect infrastructure from corrosion. Recent solicitations show state and local bodies purchasing anode installation and replacement services, cathodic protection testing and monitoring systems, and component materials such as magnesium anodes for water storage tanks and deep-well installations. The California Department of Water Resources issued an IFB in May 2026 for comprehensive cathodic protection services across five State Water Project facility locations, requiring installation, repair, replacement, remote monitoring, and database management of anode systems on a three-year initial term with one-year renewal options. San Bernardino County and the Orange County Transportation Authority have posted related facility maintenance and fastener procurement notices that tangentially involve corrosion-protection materials as part of broader supply-chain contracts, though the anode-specific work is concentrated in water-infrastructure maintenance rather than transportation or general facility operations.

Activity under this code appears concentrated in California, where the California Department of Water Resources' IFB #10215192 (due June 16, 2026) represents the most directly relevant recent opportunity. That solicitation requires California Class A, C-10, and C-57contractor licenses, a minimum five-year cathodic protection installation track record, and in-state service shop location, with a mandatory 3.0% Disabled Veteran Business Enterprise participation commitment and Small Business preferences available. Compensation is structured on hourly labor rates, equipment hourly rates, and materials at cost plus 15%, with annual escalation based on the U.S. Department of Labor Employment Cost Index beginning June 1, 2027. The contract includes a 10% bidder's bond requirement and mandatory pre-bid conference on June 2, 2026 at the Delta Field Division in Byron. No other recent opportunities in the block show direct anode procurement; the San Bernardino and Orange County notices are tangential parts-and-supplies or fastener contracts with no anode-specific language.
