UNSPSC 41104929: Laboratory filter papers

Used for separating different substances of different physical states.

UNSPSC 41104929 Laboratory filter papers is a Commodity code, but the recent state and local solicitations tagged under it do not reflect laboratory filter paper procurement. Instead, the posted opportunities show water treatment plant membrane and filtration system replacements and upgrades — reverse osmosis elements, submerged microfiltration membranes, and ERU filters for municipal water recycling and school facility operations. The work spans equipment rehabilitation, membrane supply and qualification, and filter replacement at operational treatment facilities rather than laboratory consumables. Issuing bodies include regional water districts, county utilities, and school districts. Collier County in Florida is procuring comprehensive reverse osmosis system rehabilitation involving 1,512 RO elements, pressure vessels, and SCADA controls; West Basin Municipal Water District in California is pre-qualifying suppliers of replacement submerged microfiltration membranes for an existing water recycling facility; and Forsyth County Schools is requesting proposals for ERU filters with minimal additional scope detail in the posted notice.

Activity under this code appears concentrated in California and Florida. Collier County's RO Skid Rehab project (Bid No. 26-8646), an IFB due April 24, 2026, carries an anticipated budget of $4,000,000 and requires OEM status for membrane systems, three municipal rehabilitation projects within ten years, and compliance with Florida Building Code and ASME standards. West Basin's microfiltration membrane pre-qualification (RFQTH0131), an RFQ due May 26, 2026, seeks suppliers able to provide direct replacements for Scinor and Memcor modules, with NSF-60 and NSF-419 certifications and three years of municipal supply experience. Forsyth County Schools' ERU filter proposal (P2609) closed July 7, 2026, with limited scope documentation available. The code mismatch — laboratory filter paper taxonomy applied to operational water treatment procurement — signals potential classification drift in state and local systems; business development professionals should verify UNSPSC tagging accuracy with issuing bodies before pursuing opportunities under this code.
