UNSPSC 40182100: Seamless brass tubes

Tubes made of seamless brass

UNSPSC 40182100 Seamless brass tubes is a Class code under which state and local governments procure copper and brass tubing products for water infrastructure, facility maintenance, and industrial applications. Recent solicitations show actual procurement focused on copper tubing rather than seamless brass tubes specifically — the state and local opportunities posted under this code reflect demand for Type K soft copper tubing in various gauges, copper sulfate chemicals, and copper-based materials for distribution and treatment systems. Issuing bodies include state departments (Texas Department of Criminal Justice), county water districts (Alameda County Water District, Pasco County), and county transportation authorities (Santa Clara County). The code sees activity across multiple issuing-body types, though water and utility agencies represent the primary recent buyers.

Recent activity clusters in California and Texas. The Alameda County Water District issued an IFB on April 22, 2026, for 8,000 feet of Cambridge-Lee Industries Type K soft copper tubing in three sizes (3/4" and 1" diameters) for delivery to its Fremont headquarters, with bids due April 27, 2026. The Texas Department of Criminal Justice posted an IFB (solicitation IW245930) for copper tubing with an April 7, 2026, bid deadline and firm pricing required for 30 days post-opening. Pasco County, Florida, issued an RFQ (RFQFP261004) on June 3, 2026, for large copper sulfate crystals and liquid copper sulfate on an as-needed indefinite-quantity basis, with proposals due June 26, 2026. A Santa Clara County IFB (ITBRDAFY260694) posted April 29, 2026, for the Central Expressway Pavement Rehabilitation Project includes removal and replacement of inductive traffic loops and related infrastructure but is tangentially related to the seamless brass tubes code. The code shows steady but limited recent activity concentrated in the West and South.
