All records — every source, converted

Every record for this item, from all sources together, converted to US dollars. The minimum, median and maximum below are calculated across all sources and are descriptive of these records. They are not the benchmark — the benchmark is computed per currency and shown below. Why both exist.

How order size relates to unit price

Count unit. One “unit” can be a tablet or a bottle, a box of 10 or a box of 100, so part of any price difference here is pack size, not price.

122 records from 66 tenders, priced per unit. Records in other units are on their own tabs: a quantity only compares within one unit.

The line is the median unit price in each quantity band. It describes these records. It does not show that ordering more caused a different price: large and small orders differ in buyer, product form and competition. These are chart figures, not a benchmark. Order size across all items →

Source records

142 records — every price links back to its source contracting process.

An OCID (Open Contracting ID) is the permanent identifier the publisher gives to one contracting process — a single tender, from notice through to award. It is how a figure on this site is traced back to the public record behind it. Rows sharing an OCID come from the same tender, not from separate purchases. More on what an OCID identifies →

Published — the publisher gave a unit price. Derived — we divided the line total by the quantity; how prices are derived. Not averaged — the record is shown but kept out of the benchmark, because the amount is a line total rather than a unit price, or the unit names a category rather than a measure; what is counted. Units are the publisher’s own and are not normalised.
