The preparation 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.
This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union .
ANNEX Identification number of the additive Name of the holder of authorisation Additive Composition, chemical formula, description, analytical method Species or category of animal Maximum age Minimum content Maximum content Other provisions End of period of authorisation Content of element (Cu) in mg/kg of complete feedingstuff with a moisture content of 12 % Category of nutritional additives. Functional group: compounds of trace elements 3b409 — Dicopper chloride trihydroxide Characterisation of the additive : Chemical formula: Cu 2 (OH) 3 Cl CAS Number: 1332-65-6 crystal form atacamite/paratacamite in a 1:1 to 1:1,5 ratio Purity: min. 90 % alpha-crystal: min. 95 % in the crystalline product Cu content: min. 53 % Particles < 50 μm: below 1 % Analytical method ( 1 ) : For the identification of dicopper chloride trihydroxide atacamite/paratacamite crystal forms in the additive: X-ray diffraction (XRD). For the determination of total copper in the additive and premixtures: — EN 15510: Inductively Coupled Plasma — Atomic Emission Spectrometry (ICP-AES), or — CEN/TS 15621: Inductively Coupled Plasma – Atomic Emission Spectrometry (ICP-AES) after pressure digestion. For the determination of total copper in feed materials and compound feed: — Atomic Absorption Spectrometry (AAS), or — EN 15510, or — CEN/TS 15621. All animal species — — Bovine — Bovine before the start of rumination: 15 (total) — Other bovine: 35 (total) Ovine: 15 (total) Piglets up to 12 weeks: 170 (total) Crustaceans: 50 (total) Other animals: 25 (total) 1. The additive shall be incorporated into feed in the form of a premixture. 2. For user safety: breathing protection, safety glasses and gloves should be worn during handling. 3. The following words shall be included in the labelling: — For feed for sheep if the level of copper in the feed exceeds 10 mg/kg: ‘The level of copper in this feed may cause poisoning in certain breeds of sheep.’ — For feed for bovines after the start of rumination if the level of copper in the feed is less than 20 mg/kg: ‘The level of copper in this feed may cause copper deficiencies in cattle grazing pastures with high contents of molybdenum or sulphur.’ 16 April 2022 ( 1 ) Details of the analytical methods are available at the following address of the Reference Laboratory: http://irmm.jrc.ec.europa.eu/EURLs/EURL_feed_additives/Pages/index.aspx
