UNSPSC 31151618: Longwall chain

Chain used in conjunction with flights to move coal from where it is being mined to conveyors. High impact resistant chain for use on heavy duty longwall haulage and conveyors.

UNSPSC 31151618 Longwall chain is a Commodity code that covers industrial and utility chains for operational and maintenance applications, though recent state and local solicitations show minimal direct activity under this code. The City of Tampa Purchasing Department issued RFQ 26P00328 in May 2026 seeking general-purpose chain inventory — including transport grade 70, alloy steel grade 100, and proof coil chains in multiple sizes and gauges — to support departmental operational needs across municipal divisions. The solicitation called for delivery within five business days of order, FOB Destination, with bidders to submit electronic quotes by June 15, 2026; the resulting contract would run for one year with payment at approximately 30 days following receipt and acceptance. The Tampa opportunity reflects a straightforward commodity supply procurement with competitive pricing as the primary evaluation factor, though no explicit set-aside designations were noted in the available documentation.

Recent activity under this code appears limited to Tampa-area municipal procurement. A second opportunity posted simultaneously — Sourcewell RFP 061626 for Law Enforcement Equipment, due June 16, 2026 — was tagged under the chain code but does not align with longwall or industrial chain procurement and likely represents a tagging error. The Tampa RFQ remains the sole documented state or local solicitation directly relevant to the code's scope in the current opportunities block. State and local procurement activity under this Commodity code appears sparse; the Tampa chain-inventory procurement is the primary signal of current buying activity in the market.
