UNSPSC 31241902: Diamond turned domes

UNSPSC 31241902 Diamond turned domes is a Commodity code that in recent state and local solicitations indexes microscopes, optical equipment, and accessory components used in laboratory and educational settings. State and local buyers—including state education departments and cooperative purchasing networks—solicit this equipment through indefinite-quantity requirements agreements that consolidate volume purchases and establish firm fixed pricing across multiple jurisdictions. Vendors responding to these opportunities must meet mandatory insurance, certification, and compliance requirements, including debarment certification, equal employment opportunity attestation, and Texas Government Code and federal regulatory compliance where applicable. Warranty terms and repair accountability during the warranty period are standard contractual elements.

The Texas Comptroller of Public Accounts posted the most recent activity for this code, soliciting microscopes and accessories through the Texas Cooperative Purchasing Network (TCPN) with a response deadline of September 1, 2026 (Solicitation 304T27490M2). Michigan's State government also posted a Notice of Intent for RFP 250000002612 regarding optical lenses and frames (July 31, 2026 response deadline), though the full RFP scope and evaluation criteria were not disclosed in the posting summaries. Recent activity concentrates in Texas and Michigan. Respondents to Texas TCPN solicitations must complete Attachments B through F, including a mandatory price sheet establishing line-item unit costs and warranty provisions. The TCPN agreement structure permits individual state and local agencies to exercise independent purchasing authority against pre-negotiated rates, extending the response period 120 days following the stated due date.
