UNSPSC 42183044: Tangent screens

In this classification, this commodity indicates a product used as an instrument to map a patient's peripheral vision by recording his/her response to test objects placed on the screen while the patient's stare is fixed on center target in a medical setting. US FDA regulates Tangent screens under 21 CFR 886.1810 and under FDA product code HOJ. Most nations, for tariff and trade purposes, schedule these products under HS 901811.

UNSPSC 42183044 Tangent screens (Commodity) covers optical equipment accessories, though recent state and local solicitations under this code show activity primarily in microscopes and related laboratory equipment rather than tangent screens specifically. State and local governments buy microscopes, microscope accessories, and optical components to support educational and laboratory functions across school districts, state agencies, and other public bodies. The Texas Comptroller of Public Accounts and the State of Michigan have posted recent solicitations in this space, indicating ongoing demand from state-level procurement offices managing cooperative purchasing vehicles and standalone RFPs. Vendors responding to these opportunities must complete mandatory certifications, provide insurance documentation, and establish firm fixed-price unit costs for equipment and accessories, with warranty terms covering defects and vendor accountability during the warranty period.

Recent activity centers on Texas and Michigan. The Texas Comptroller of Public Accounts issued RFP 304T27490M2 for microscopes and accessories through the Texas Cooperative Purchasing Network (TCPN) on August 5, 2026, with responses due September 1, 2026—an indefinite-quantity, requirements-type agreement enabling multiple state and local agencies to access pre-negotiated pricing. The State of Michigan posted Notice of Intent NIA14722600000006731 for RFP 250000002612 regarding optical lenses and frames on July 27, 2026, though the full RFP scope and contract value remain undisclosed in available materials. The Texas cooperative purchasing vehicle structure consolidates volume purchases across the state education and laboratory procurement base, with individual agencies maintaining independent purchasing authority under the negotiated agreement.
