UNSPSC 60104721: Inertia moment apparatus

A device used to experiment the inertia moment which refers to the measure of an object's resistance to changes in its rotation.

UNSPSC 60104721 Inertia moment apparatus is a Commodity code that in recent state and local procurement activity represents a misclassification or tagging error; the code shows no substantive match to the solicitations posted under it. The opportunities tagged with this code instead reflect broad educational materials and supplies procurement by school districts, spanning classroom instruction supplies, science lab equipment, STEM kits, technology services, and related instructional products. Katy Independent School District (Katy ISD) in Texas, Cobb County School District in Georgia, and Cartwright Elementary School District in Arizona—all large K-12 systems—are among the recent issuers, along with independent school districts in Texas (Donna ISD, Los Fresnos CISD), the Savannah-Chatham County Public School System in Georgia, Valencia College in Florida, and Seminole County Schools in Florida. These buyers solicit both through RFP and IFB processes, typically requiring percentage discounts off catalog pricing, F.O.B. Destination delivery including inside delivery to school sites, and often awarding multiple vendors to establish approved vendor lists for as-needed purchasing. The scope is almost exclusively K-12 and higher education institutional supplies and equipment rather than industrial instrumentation or laboratory apparatus for measuring moment of inertia.

Recent activity concentrates in Texas, Georgia, and Florida, with scattered opportunities in Arizona. Representative solicitations include Katy ISD's RFP #2428KD-A for teaching and instructional materials across multiple curriculum areas, due May 29, 2026; Cobb County School District's IFB B26128 for science specimens, chemicals, and equipment across 112 school sites, due June 16, 2026; Cartwright Elementary School District's RFP (through the SAVE cooperative) for STEM and college & career readiness kits and programs spanning multiple Arizona jurisdictions, due June 8, 2026; and DeKalb County School District's RFQ 26-724 for comprehensive K-12 science instructional resources, due March 12, 2026. Estimated annual volumes in these procurements range from $32,000 to $1.3 million depending on district size and scope. The code's mismatch to actual buying activity suggests vendors tracking this UNSPSC code should verify tagging accuracy at the class or family level before pursuing; the underlying educational materials and supplies opportunity is active and ongoing, but this specific commodity designation does not reliably flag relevant solicitations.
