What we do


Authorised Suppliers of Biocidal Silver and Copper

Tarn-Pure is a founding member of the EU Biocidal Copper Task Force and the EU BPR Silver Task Force.

We are included in ECHA’s “Article 95” list as authorised suppliers of metallic copper for product types 2, 5, and 11; and as authorised suppliers of metallic silver for PTs 2, 4, 5, 9 and 11.

Through membership of the Silver Task Force Tarn-Pure is a “Review Programme Participant” for the Silver Review being conducted by KemI (the Swedish Chemical Agency) and is automatically authorised to place elemental silver, which is defined as an “existing active substance”, on the market under the terms of Regulation EU/528/2012 – The Biocidal Products Regulations or the “BPR”.

Through membership of the Biocidal Copper Task Force Tarn-Pure is supporting the review of elemental copper as a biocidal active substance, and is authorised to place this “new active substance” on the market in the Member States of the territory of the BPR that have been granted derogations from the March 2012 decision of the European Parliament to “non-include” copper as a biocidal active substance. The derogations are valid until the Review of copper by ANSES, the French rapporteur, is completed and copper is listed in Annex I of the BPR. Approval for the use of copper as a biocidal active substance for PTs 2, 5 and 11 is expected to be confirmed before the end of 2018.
