UNSPSC 40181604: Welded brass multiport tube

Welded tube made of brass that has been multiported

UNSPSC 40181604 Welded brass multiport tube is a Commodity code that captures copper and copper-alloy tubing products procured by state and local water utilities, departments of corrections, and county environmental agencies for distribution system maintenance, facility infrastructure, and chemical treatment applications. Recent solicitations show state and local buyers purchasing copper tubing in bulk quantities for plumbing and water system work, copper sulfate for water treatment, and related piping materials. The issuing bodies include specialized state procurement offices managing correctional facility operations, county water districts, and county environmental services departments. Work under this code centers on supply contracts for standardized piping materials—typically Cambridge-Lee Industries brand Type K soft copper tubing in specified diameters and lengths, or commodity chemicals such as copper sulfate crystals and liquid formulations for algae and aquatic plant control.

Recent activity spans Texas, California, and Florida. 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 3/4" and 1" diameters to be delivered to its Fremont headquarters by April 27, 2026. The Texas Department of Criminal Justice Contracts and Procurement office posted an IFB (IW245930) on March 23, 2026, for copper tubing with a bid deadline of April 7, 2026, requiring bidders to meet Texas identification and E-Verify compliance, state ownership preferences under 34 TAC Rule 20.306, and standard TDCJ payment and indemnification terms. Pasco County, Florida solicited vendors via RFQ (RFQFP261004) for an as-needed supply of large copper sulfate crystals and liquid copper sulfate, with proposals due June 26, 2026. A third Santa Clara County procurement (ITBRDAFY260694) issued in April 2026 involved pavement rehabilitation rather than tubing supply and appears misclassified under this commodity code.
