UNSPSC 31201711: Parylene conformal coating

A chemical vapor deposited polymer used to coat electronic component circuitry for protection against environmental or physical damage

UNSPSC 31201711 Parylene conformal coating is a Commodity code that, based on recent state and local solicitations, shows minimal activity directly aligned with its nominal scope. The three most recent opportunities tagged to this code involve concrete sealant services, fusion tape procurement, and law enforcement equipment — none of which represent parylene conformal coating applications. State and local governments do procure protective coatings and materials for infrastructure maintenance and equipment preservation, but the recent activity under this code does not reflect parylene-specific demand. When activity does appear under this code, it tends to come from transportation authorities, counties, and cooperative purchasing vehicles serving multi-jurisdictional public entities, though the frequency and consistency of actual parylene coating solicitations remain unclear from the available record.

The Orange County Transportation Authority (OCTA) in California issued IFB 250318 for concrete sealant services on October 7, 2026, with bids due October 14, 2026 — a $250,000 prevailing wage contract for surface preparation and application of various sealants at transportation facilities and OC Streetcar platforms. Dallas County, Texas posted a brief IFB 2100758 on August 28, 2026, for fusion tape, 1 inch by 0.020 inch by 30 feet, due October 1, 2026. Sourcewell, a State of Minnesota cooperative purchasing vehicle, issued RFP 061626 on behalf of participating entities in Washington state and beyond, seeking law enforcement equipment solutions for a multi-jurisdictional network. The code shows activity across California, Texas, and the upper Midwest cooperative purchasing network, but the mismatch between the code's nominal parylene-coating scope and the actual solicitations suggests this code may be misapplied in state and local procurement systems or that genuine parylene conformal coating demand under this code is not currently visible in public notice records.
