UNSPSC 13111079: Polyamide 4-6

Nylon in the form of an aliphatic polyamide resulting from the polycondensation of 1,4 diaminobutane and adipic acid.

UNSPSC 13111079 Polyamide 4-6 is a Commodity code representing raw thermoplastic materials for pavement striping and road markings that state and local governments procure in bulk quantities for ongoing infrastructure maintenance. State and local buyers under this code are sourcing thermoplastic binder-based compounds formulated with glass microspheres, pigments, and mineral fillers—materials specified to precise compositional ranges (binder 18–26% by weight, reflective spheres 30–40%, titanium dioxide 10–15%, fillers 20–40%)—packaged in 50-pound meltable bags for delivery to street maintenance departments. Issuing bodies span mid-sized cities (Phoenix, Dallas, Savannah, Fort Worth), county transportation agencies (Harris County, Santa Clara County, Fort Bend County, Marion County, Bryan County), and special-purpose municipal districts (South Fulton). These jurisdictions post thermoplastic procurement notices across multiple solicitation types—IFBs for raw material supply, ITBs for applicator equipment and installation services, and on-call service contracts for striping and marking installation—indicating sustained, routine demand for thermoplastic feedstock to support pavement maintenance programs.

Geographic activity clusters in the Southwest (Arizona, Texas) and Southeast (Georgia, Florida), with secondary activity in California and Texas. Representative recent solicitations include the City of Phoenix's IFB 260348, due July 17, 2026, for thermoplastic pavement marking raw material in granular or pelletized form with a five-year contract term commencing February 15, 2027, requiring daily inventory support and delivery within 30 days of order; Fort Bend County's IFB 26-038, closed February 24, 2026, for thermoplastic traffic coating services across multiple widths and marker types under a primary-secondary-tertiary vendor structure running through March 31, 2031; and the City of Fort Worth's 2026 On-Call Pavement Markings Contract (CPN 106517), due February 19, 2026, covering 198 line items of thermoplastic, polyurea, and preformed marking applications with a one-year initial term and up to four renewal options. The Phoenix opportunity is the most concrete current signal—a formal five-year supply contract with firm pricing for year one and escalation provisions thereafter, indicating sustained municipal investment in thermoplastic infrastructure.
