UNSPSC 47131903: Plugging compound

UNSPSC 47131903 Plugging compound, a Commodity code, describes materials and services for sealing, patching, and detecting leaks in building systems and infrastructure. State and local governments procure leak detection services, polymer compounds for water treatment operations, specialty chemicals for forensic applications, and related maintenance compounds under this code. The issuing bodies span school districts, county water and wastewater utilities, and county forensic agencies. Recent solicitations show a mix of facilities-maintenance contracting (leak detection on an as-needed basis across district-owned buildings), municipal water-treatment operations (polymer procurement for sludge dewatering and thickening), and specialized institutional procurement (forensic laboratory chemicals).

Activity appears concentrated in Florida, Georgia, California, and Texas. Pinellas County School Board posted an ITB for comprehensive leak detection services across district facilities on September 1, 2026, with bids due September 29, 2026, and a contract value of approximately $75,000 annually. Gwinnett County Board of Commissioners solicited sealed bids on solids dewatering and thickening polymer for water reclamation facilities on July 1, 2026, with bids due July 30, 2026, under a four-year annual contract beginning October 19, 2026. West Basin Municipal Water District in California posted an RFB on August 10, 2026 for sodium hypochlorite tank replacement and associated bypass system installation at a recycled-water treatment plant. Harris County Institute of Forensic Science issued an ITB for specialty chemicals and industrial gases with a July 20, 2026 response date. The code shows active but modest procurement volume concentrated in water utilities and school district maintenance.
