NIGP 13547: Refractories, Castable

NIGP 13547 Refractories, Castable is an Item code covering heat-resistant materials and components used in high-temperature industrial applications within state and local government facilities. The recent opportunities block contains no active solicitations for castable refractories. The single substantive posting in the available records is a Sourcewell cooperative purchasing RFP (061626) issued on behalf of multiple Washington state counties and participating entities nationwide for law enforcement equipment — a scope entirely outside the refractories category. The Williamson County Purchasing Department notice is an administrative relocation announcement with no procurement content.

Without active state and local solicitations under this Item code in the recent-opportunities dataset, no geographic concentration, issuing-body mix, or representative contract detail can be established from the source. The code does not appear in current state and local procurement activity tracked in the available records as of October 2026.
