About NIGP 55975
NIGP 55975 Special Parts (Not Otherwise Identified), an Item code, captures transit authority and county purchasing of fasteners, connectors, cables, and other discrete mechanical components that do not fit into commodity-specific NIGP classes. State and local governments under this code procure stainless steel washers, lock washers, electrical connectors in multiple pin configurations, power cables, and specialty replacement parts for fleet maintenance and facility operations. The issuing bodies are predominantly transit authorities (notably Dallas Area Rapid Transit Authority, operating in Dallas County, Texas, and Charlotte Area Transit System in North Carolina) and county governments, which solicit these items through purchase orders and RFQs with Net 30 payment terms, FOB Destination freight pricing, and strict delivery-schedule enforcement.
Recent activity concentrates in Texas and North Carolina.

Dallas County posted an IFB for Formula "409" multi-surface and glass cleaner due August 5, 2026.
