Public tenders, sector by sector.
A supplier does not ask where tenders are published in general, but where their sector is bought. Each page below joins two things the rest of this site keeps apart: the slice of the official CPV vocabulary that carries the sector, out of 9,440 codes, and the buyers who publish it outside the national portals across 153+ countries.
Why the sector view is different from a code list
Codes describe what a buyer says it is buying; sectors describe how a market actually behaves. The same hospital publishes under medical, IT, construction and catering codes in one month, and the supplier who follows only one of them sees a fraction of the buyer. These pages exist to hold both views at once, which is also how TRINTA's radar reads: not by code, but by what a company sells, against the full text of every notice.
