UNSPSC 31371212: Special service castable

A castable refractory that is used for special purposes. This is used to provide outstanding erosion resistance, abrasion resistance, spalling resistance and high strength on special parts of boiler interior, kiln, steel manufacturing, induction furnace and others.

UNSPSC 31371212 Special service castable, a Commodity code, encompasses refractory and specialized castable materials that state and local governments procure for industrial, infrastructure, and equipment applications. The recent opportunity record for this code shows minimal relevant procurement activity; state and local issuing bodies are not currently soliciting castable materials under this code at scale based on the available recent notices.

The most recent opportunity associated with this code is a Sourcewell cooperative purchasing RFP (#061626, due June 16, 2026) for law enforcement equipment on behalf of participating entities including Franklin County, Grant County, Grays Harbor County, Chelan County, and Yakima County in Washington state, along with other jurisdictions across the United States and Canada. This solicitation does not align with the castable materials scope and appears to be misclassified under the code. A second recent notice from Williamson County, Texas (Solicitation 26OTHER73, posted July 14, 2026) is an administrative relocation announcement with no procurement content and does not represent a buying opportunity. The absence of substantive recent castable-material solicitations suggests limited current state and local demand for procurement under this code, warranting close monitoring of upstream family and class codes for related opportunities in refractory materials and specialized industrial supplies.
