UNSPSC 30103610: Crib block

Treated wood blocks used in underground mining for supporting roof and equipment.

UNSPSC 30103610 Crib block is a Commodity code that does not reflect the recent state and local solicitation activity. The code's nominal scope—structural support blocks for crib construction—aligns with heavy timber framing and foundation work, yet the six opportunities posted between February and June 2026 across state and local procurement systems show no purchases of crib blocks. Instead, the opportunities tagged to this code involve residential roof replacement, door hardware installation, pergola structural repairs, grandstand handrail replacement, and park pavilion construction—work that may incidentally use blocking or structural support materials but does not center on crib block procurement. The issuing bodies include city community development and public works departments (Jackson, Michigan; Bridgeport, Connecticut), county parks and recreation authorities (Marion County, Florida; Henry County, Georgia; Gwinnett County, Georgia), and county construction services (Rockdale County, Georgia). Sourcewell, a Minnesota cooperative purchasing vehicle, also posted a broad law enforcement equipment RFP that was mistakenly tagged to this code and is entirely unrelated to building materials.

The geographic spread spans Michigan, Connecticut, Florida, and Georgia, with the most recent and highest-dollar activity concentrated in Georgia (Henry County's two N. Mt. Carmel Park RFPs in March and April 2026, and Rockdale County's on-call interior construction contract in March). Representative recent opportunities include the City of Jackson's sealed bid for roof and porch work at 225 W High Street (due June 24, 2026, rebidded from an earlier March 9 deadline), Gwinnett County's informal quote for pergola replacement at Hudlow Tennis Center (due June 25, 2026), Marion County's ITB for grandstand handrail repair (due April 23, 2026), and Henry County's RFP #26-35 for N. Mt. Carmel Park site and restroom construction (due April 21, 2026). The code shows no material procurement activity aligned with its nominal classification and should be monitored only if a vendor's estimating systems have incorrectly tagged relevant work to this code across state and local procurement channels.
