UNSPSC 15111709: Marker and dye

Markers and dyes are used for the purpose of differentiation between different commercial grades of gasoline and are also used to distinguish products attracting different duty levels, or to identify specialist products, e.g. aviation gasoline. Markers show no visible effect in fuel but on extraction with a solvent, will impart distinctive colors. Other markers can require UV or IR spectroscopy to reveal their presence and may comprise bio or nano-Materials. These techniques can be useful in providing inventory control or in deterring theft.

UNSPSC 15111709 Marker and dye (Commodity) does not align with the recent state and local procurement activity posted under this code. The nine opportunities in the source are solicitations for aviation fuel, gasoline, diesel fuel, and related fuel delivery services—none involve markers or dyes in the sense the code describes. The mismatch suggests either a classification error in how state and local procurement offices have tagged these opportunities or a data integrity issue in the source provided.

The actual activity under this code tag consists of fuel supply and delivery contracts across multiple jurisdictions. State and local buyers include school districts (Cobb County School District, Hillsborough County Public Schools), counties (Ventura County, Jefferson County, Collier County), cities (City of Little Rock, City of Tucson), college systems (Texas State Technical College), airport authorities (Collier County Airport Authority, Peachtree City Airport Authority), and cooperative purchasing vehicles (Sourcewell). Opportunities span aviation fuel (Jet-A, 100LL Avgas) for municipal airports and law enforcement operations, and gasoline and diesel fuel for fleet and campus operations. Recent solicitations include Texas State Technical College RFP #62 for aviation fuel services with an April 1, 2027 start date and estimated annual volumes of 675,000 gallons of Jet-A and 97,000 gallons of 100LL Avgas; Hillsborough County Public Schools ITB 26205 for approximately 1.75 million gallons annually of ultralow sulfur diesel fuel, estimated at $5.5 million annually; and Ventura County RFP 6252 for approximately 2.02 million gallons across four product categories with $4.6 million historical annual spend. Activity is concentrated in Texas, Florida, Arizona, Georgia, California, and Minnesota. The City of Tucson Police Department is procuring roughly 50,000 gallons of Jet-A annually for law enforcement aviation, while Sourcewell is aggregating demand across multiple member entities through a cooperative purchasing vehicle with a September 17, 2026 proposal deadline. Given the mismatch between the code's nominal scope and actual opportunities, this code does not represent a viable pursuit category for vendors supplying markers or dyes to state and local government.
