UNSPSC 11191801: Manganese slag

A byproduct produced during processing of manganese ore

UNSPSC 11191801 Manganese slag is a Commodity code that encompasses scrap metal, aluminum, and appliance recycling services purchased by state and local governments. However, the recent solicitations tagged to this code show minimal direct procurement of manganese slag itself; instead, they reflect a much broader market for general metals recycling—ferrous and non-ferrous metals, mixed scrap, electronic waste, and appliances. State and local buying offices are using this code to solicit collection, transport, processing, and revenue-sharing arrangements with recycling vendors. Work centers on pickup and removal of scrap metals and e-waste from municipal facilities, landfills, and transfer stations; processing at certified facilities; weighing on state-certified scales; and settlement based on published commodity market indices (primarily the American Metal Market monthly averages). Counties, cities, state departments of transportation, and special-purpose districts are the primary issuing bodies.

Recent activity spans California, Georgia, Kentucky, Oregon, Michigan, and Arizona. Sacramento County Department of Waste Management and Recycling (RFQ 2026GEN0053, due June 9, 2026) sought bids for collection and recycling of mixed metals and unprocessed appliances with 10,800–11,775 projected tons annually. DeKalb County, Georgia (ITB 2026-082, due July 23, 2026) solicited a three-year contract for supply of hot-rolled steel plates for roadway projects. Ventura County issued two separate RFBs on May 28, 2026 (RFB 6527 for metal recycling and RFB 6528 for e-waste recycling, both due June 24, 2026) structured as revenue-return agreements with settlement tied to American Metal Market pricing. Clayton County, Georgia (ITB 26-65, due June 25, 2026) requested e-waste disposal services with fees deducted from commodity revenue. The Kentucky Transportation Cabinet (RFBs 2600000451 and 605 2600000483, posted March 2026) has issued multiple solicitations for scrap metal and aluminum recycling from highway maintenance districts, with multiple awards to responsive bidders. Marion County, Oregon (RFQ PW1772-26, due February 24, 2026) and the City of Detroit (RFQ 543297, due February 10, 2026) likewise pursued scrap removal and sales arrangements. The market shows consistent use of percentage-of-spot-price and per-pound pricing models, mandatory local small business and first-source hiring requirements in some jurisdictions, prevailing wage compliance in California procurements, and revenue-sharing structures where the contractor pays the municipality rather than the reverse.
