UNSPSC 10171615: Potassium sulphate

A soluble substance used in making fertilizers

UNSPSC 10171615 Potassium sulphate (Commodity) covers granular road maintenance salt and de-icing materials that state and local governments purchase for snow and ice control on municipal roadways. The scope of work centers on bulk rock salt meeting ASTM D632 specifications—minimum 95 percent sodium chloride content, specified gradation, maximum 3 percent moisture, and free-flowing condition—delivered to street maintenance operations on as-needed, seasonal schedules. Issuing bodies soliciting under this code include cities and municipalities with winter weather obligations; the recent activity shows city-level procurement offices managing direct supply arrangements with performance specifications and multi-year renewal options. Contracts typically run one year with optional extensions, firm pricing guarantees of 60 days minimum with post-six-month adjustments tied to Consumer Price Index or Product Price Index changes, and F.O.B. delivered terms that include all packaging and freight.

The City of Lubbock, Texas represents the primary recent buyer under this code, posting an ITB (ITB 26-19689-YB) due June 10, 2026, for approximately 1,000 tons of granular road maintenance salt with delivery to the Street Maintenance Department at 502 North Interstate 27. The City applies a Texas local-vendor preference under Government Code 271.9051, allowing local bidders within 5 percent of the lowest non-resident bid to win on contracts under $500,000, and considers HUB (Historically Underutilized Business) goals in award decisions. Contractors must carry $1 million commercial general liability per occurrence with $2 million aggregate, $1 million automobile liability, and statutory workers' compensation coverage with $1 million employer's liability; delivery must occur within 48 hours of purchase order placement and be completed within five business days. No pre-bid meeting is scheduled, and bids are submitted electronically through the Bonfire portal or in hard copy to the Director of Purchasing and Contract Management.
