UNSPSC 31371101: Mullite bricks

UNSPSC 31371101 Mullite bricks is a Commodity code that nominally covers refractory brick products, but the recent state and local contract opportunities indexed under this code show minimal relevant procurement activity. Of the four most recent opportunities posted, only one—the City of Statesboro, Georgia's sealed bid for exterior restoration and window replacement at the Averitt Center for the Arts (PE61650NONST2026000000051)—contains work that could involve mullite or similar refractory materials. That solicitation encompasses brick repointing, window replacement, and elastomeric wall coating; the brick repointing scope may entail specialty brick products, though the posting does not specify material grades or refractory properties. The remaining three opportunities are misaligned with the code: one is an administrative relocation notice for Williamson County Purchasing (Texas), another is a mechanical vegetation treatment RFP from Seminole County (Florida), and a third is a cooperative purchasing RFP for law enforcement equipment through Sourcewell on behalf of multiple jurisdictions (Washington state and beyond).

The geographic spread is limited and fragmented across the sparse activity. The one potentially relevant opportunity—the Statesboro brick repointing work—originated in Georgia and closed March 5, 2026. The code shows no concentrated procurement signal within a particular state or region, and no repeat buyer pattern appears in the recent records. Firms pursuing mullite brick opportunities in state and local procurement should treat this code as a low-signal indicator and cross-reference related codes for masonry, refractories, or building materials restoration to identify active demand.
