UNSPSC 51201829 Tetramisole hydrochloride is a Commodity code that captures pharmaceutical products procured by state and local health agencies. Recent activity under this code reflects state health department procurement of vaccines and related pharmaceutical supplies. State and local governments use this code to classify purchases of specific active pharmaceutical ingredients and finished pharmaceutical products for public health programs, disease prevention initiatives, and immunization campaigns. The mix of issuing bodies soliciting under the code centers on state health departments and subordinate public health agencies responsible for vaccine acquisition and disease control.

Activity under this code appears concentrated in state-level health procurement. The most recent opportunity on record is the Mississippi State Department of Health's sole source notice for Yellow Fever Vaccine from Sanofi Pasteur, Inc., posted July 13, 2026, with an objection deadline of August 3, 2026. The notice invites challenges to the sole source designation and establishes a process for alternative vendors to demonstrate competitive capability; the department has not disclosed quantity, contract term, or estimated value. Geographic data is sparse — the available recent-opportunities block contains only the Mississippi solicitation, limiting visibility into broader state or regional spread of procurement activity under this code.
