UNSPSC 42183059: Photosimulators

In this classification, this commodity indicates a product used as a device that simulates the mathematic establishment of reflectance models based on a patient's eyesight in a medical setting. Most nations, for tariff and trade purposes, schedule these products under HS 901811.

UNSPSC 42183059 Photosimulators is a Commodity code that in recent state and local activity covers laboratory analytical equipment and related instruments used by government facilities for quality control and environmental monitoring. The City of Tampa's Solid Waste & Environmental Program Management issued an RFQ in June 2026 for a Heck DR4900 Spectrophotometer to replace an existing unit at its McKay Bay Waste to Energy facility, exemplifying the direct-replacement purchasing pattern that dominates the code. State and local issuing bodies under this code include solid waste and environmental departments, with no pattern of repeat solicitations in the recent opportunities block suggesting concentrated demand from a narrow buyer base.

Recent activity is sparse and geographically dispersed. The Tampa spectrophotometer RFQ (26P00372, due June 12, 2026) represents the primary recent opportunity directly aligned with the code's nominal scope. Two other opportunities posted in the recent block—Sourcewell's Law Enforcement Equipment RFP (#061626, due June 16, 2026) and Klein Independent School District's Career Technical Education RFP (#26-101, due June 5, 2026)—do not reflect photosimulator or spectrophotometer procurement and show mismatch with the code's intended application. The spectrophotometer solicitation shows firm fixed pricing, a 60-day price-hold requirement, and compliance with City of Tampa procurement conditions including E-Verify verification and proof of insurance prior to award. Geographic spread based on relevant recent activity is limited to Florida; the source does not support evidence of comparable recent photosimulator procurement in other states.
