UNSPSC 27111829: Optical parallel

A plate with optical glass on the both side with highly precise level of parallelism. Used in measuring the level of flatness and parallelism of the micrometer measurement surface by using light wave interference.

UNSPSC 27111829 Optical parallel (Commodity) shows minimal recent activity aligned with its nominal scope; the recent opportunities posted under this code do not reflect optical or parallel equipment procurement. The Texas Office of the Attorney General issued IFB 302-27-254756 (due October 15, 2026) soliciting knives, handcuffs, leg irons, foam transport cases, crushproof protector cases with wheeled transport, travel air cases, and tourniquet pouches for statewide law enforcement use — a law-enforcement equipment buy unrelated to optical parallels. The City of Philadelphia posted a micro purchase designated "Machete" (due September 4, 2026) and the City of Dallas solicited an ID/IQ master agreement for flags (due September 11, 2026), neither of which align with the code's stated category. The coding appears to be a classification mismatch rather than genuine procurement activity under the optical parallel taxonomy.

Geographic activity appears concentrated in Texas and Pennsylvania based on recent postings, but issuing bodies include both state-level (Texas Office of the Attorney General) and municipal entities (Philadelphia, Dallas). Because the recent opportunities do not reflect actual optical parallel procurement, this code signals minimal current market relevance for vendors in that commodity space. Buyers evaluating state and local activity under UNSPSC 27111829 should treat this as a quiet code and verify category alignment before pursuing opportunities posted against it.
