International Magical Trading Standards Body

"A report for the Department of International Magical Cooperation. We're trying to standardise cauldron thickness. Some of these foreign imports are just a shade too thin — leakages have been increasing at a rate of almost three percent a year —"

- Department of International Magical Cooperation's standard work

The International Magical Trading Standards Body was an office in charge of overseeing and assessing trading practices within the wizarding world, as well as passing international legislation regarding trading standards.

History
Judging from Percy Weasley's report on the standardisation of the minimum thickness for imported cauldrons, this was where he was employed when he first joined the Ministry of Magic in 1994.
