Authorisation
The substance specified in the Annex, belonging to the additive category ‘nutritional additives’ and to the functional group ‘compounds of trace elements’, is authorised as an additive in animal nutrition subject to the conditions laid down in that Annex.
Entry into force
This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union.

The additive shall be incorporated into feed in the form of a premixture. 2. For users of the additive and premixtures, feed business operators shall establish operational procedures and organisational measures to address the potential risks resulting from their use. Where those risks cannot be eliminated by such procedures and measures, the additive and premixtures shall be used with personal breathing eye and skin protective equipment. 7 February 2034 — Piglets — Sows — Rabbits — Fish farmed in land-based aquaculture systems, other than salmonids - - 150 — Calves (milk replacer) — Salmonids farmed in land-based aquaculture systems - - 180 Other species and categories except aquatic animals farmed in marine aquaculture systems - - 120 ( 1 ) Details of the analytical methods are available at the following address of the Reference Laboratory: https://ec.europa.eu/jrc/en/eurl/feed-additives/evaluation-reports ( 2 ) Stoe Stadi P diffractometer in Guinier geometry using Cu-Κα1 radiation (Johann Gemonochromator) and a Stoe imageplate detector IP-PSD.
