"Once again, we remind the wizarding community that only wands bearing the Department's stamp are guaranteed safe"
-- unnamed spokesperson from the Department of Magical Equipment Control (DP1)
A department or office in the Ministry of Magic (DP1)
This section regulates problems with equipment such as faulty wands and loose-b0ttomed cauldrons (DP1)
The department for "Magical Equipment Control" is uncertain, especially since this group is called the "Department" of Magical Equipment Control, a misnomer no doubt resulting from the fact that it was written about in 1998 (DP1) three years before FB (which for the first time listed the various departments of the Ministry of Magic). It may be an office on its own or part of the the Misuse of Muggle Artifacts Office.
While the date printed on DP1 is 31 July 1998, the timeframe for these events is 1992-1993.
