UNSPSC 30131512: Autoclaved lightweight aerated concrete block

An aerated concrete block made lighter by the use of foam in the concrete.

UNSPSC 30131512 Autoclaved lightweight aerated concrete block is a Commodity code that in recent state and local procurement activity shows minimal relevance to its nominal scope. The single recent opportunity tagged under this code—Santa Clara County's Central Expressway Pavement Rehabilitation Project (ITB ITBRDAFY260694, due May 21, 2026)—is a general pavement and roadway infrastructure project encompassing partial depth recycling, hot mix asphalt overlay, Portland cement concrete curb and gutter installation, sidewalk replacement, ADA access improvements, traffic signal modifications, and guardrail work. The solicitation does not specify autoclaved lightweight aerated concrete block as a material requirement or line item; rather, it calls for comprehensive labor, materials, and equipment to support broad pavement rehabilitation and related improvements along a highway corridor. The mismatch between the code's product-specific name and the actual scope of work solicited suggests either misclassification in the state or local procurement system or a tangential material specification buried in the full project plans not evident in the posted summary.

Santa Clara County appears as the sole recent issuing body in the available record for this code. Geographic activity is limited to California (Santa Clara County, San Jose area). Given the single recent opportunity and its apparent misalignment with the code's nominal scope, this code shows little current activity relevant to firms specializing in lightweight aerated concrete products. Firms pursuing work under this code should verify whether the classification reflects occasional, incidental use of the material in larger infrastructure projects or represents a data-quality issue in the underlying procurement taxonomy.
