Since 1979 ZIELER & Co. has offered organic products, and we now stock a range of nearly 100 products from controlled organic sources.

These products regularly undergo quality checks by independent bodies, and the producers of certified organic products are subject to unannounced inspections several times a year.

As a supplier of organic products, ZIELER & Co. is monitored by the independent society 'Gesellschaft fuer Ressourcenschutz' (GfR). We apply annually to renew our certificate from the GfR (available to view by clicking on the picture above, Acrobat-Reader-Document). You can therefore be assured that our organic products are of the highest quality, from carefully selected sources.
