UNSPSC 30251504: Expansion shell

Expansion shells used in conjunction with roof bolts to support roof in underground mine.

UNSPSC 30251504 Expansion shell is a Commodity code that does not see meaningful recent state and local procurement activity aligned with its nominal product definition. The recent opportunities block contains thirty-two state and local solicitations posted between January and July 2026, yet only one — a roofing supplies catalog procurement issued by the City of Tucson on July 8, 2026 — bears any plausible connection to roofing-related goods and services. The remaining thirty-one opportunities are exclusively roof replacement, roof repair, roofing contractor services, and facade renovation projects that solicit labor-intensive construction work, not material goods or component supplies. The code's name and scope do not align with what state and local agencies are actually buying under this classification in the recent record.

The City of Tucson ITB for roofing supplies (due July 29, 2026) is the sole representative opportunity: an indefinite-quantity, as-needed procurement for an extensive catalog of roofing parts and materials — both stocked and special-order items — subject to ARPA federal compliance, domestic-preference provisions for U.S.-manufactured goods, and EPA recovered-materials maximization. Beyond this single solicitation, no geographic concentration, repeat issuing bodies, or pattern of activity supports pursuit of this code. The mismatch between the code's nominal scope and the construction-labor-dominated opportunities in the recent record suggests either systematic miscoding by state and local procurement offices or that this commodity code designation does not reflect current acquisition patterns in the state and local market.
