NIGP 55975: Special Parts (Not Otherwise Identified)

NIGP 55975 Special Parts (Not Otherwise Identified), an Item code, encompasses transit-system components and hardware supplies that do not fit neatly into other NIGP commodity classifications. State and local governments—particularly transit authorities—procure connectors (multi-pin and high-position-count variants), electrical cable, fasteners (bolts and lock washers), rubber articulation panels, and abrasive-sleeve assemblies under this code. The Dallas Area Rapid Transit Authority (DART) dominates recent solicitation activity, issuing multiple purchase orders across a four-month window for diverse mechanical and electrical inventory. Common contracting terms across DART's purchases include FOB Destination with freight included, Net 30 payment from the later of invoice or order receipt, triplicate invoicing, and material emphasis on timely delivery—DART reserves the right to reject and terminate for default based on failure to meet specified delivery schedules.
