UNSPSC 31162909: Isophonic clamp

A type of clamp designed to be used on hoses and pipes to reduce sound vibrations.

UNSPSC 31162909 Isophonic clamp (Commodity) does not align with the recent state and local contract opportunities posted under this code. The opportunities instead reflect procurement of traffic sign hardware, anchoring and buoy components, silo accessories, door parts and locks, telecom parts and tools, janitorial supplies, HVAC equipment, woodshop consumables, maintenance hardware, law enforcement equipment, and station alerting audio parts — none of which are isophonic clamps or related fastening systems. State and local agencies tagging these diverse solicitations under a single commodity code suggests either a taxonomy data error or widespread misclassification in the issuing bodies' procurement systems. The scope reflects fragmented, low-dollar micro purchases and blanket orders across multiple issuing bodies with no coherent product family.

Recent opportunities span Texas Health and Human Services Commission (HHS) blanket orders for facility maintenance at state supported living centers, the City of Philadelphia micro purchases, the City of Indianapolis Department of Public Works, Hillsborough County Fire Rescue janitorial supplies, the City of Austin audio systems procurement, and cooperative purchasing vehicles such as Sourcewell serving multi-state law enforcement procurement. Geographic activity clusters in Texas (HHS issues nine of the recent solicitations) and scattered city-level activity in Pennsylvania, Indiana, Florida, and Washington. Representative recent procurements include the City of Indianapolis RFB-14DPW-1817 for traffic sign hardware (response due October 15, 2026), the Texas HHS IFB HHS0017595 V2 for telecom parts and tools (response due October 2, 2026), and the City of Philadelphia B2728124 micro purchase for anchoring and buoy components (response due October 8, 2026). The code shows no coherent market signal for isophonic clamp procurement and warrants reclassification review before pursuing work under this taxonomy entry.
