The Timber Trade Federation (TTF), is a British federation of timber traders, founded in 1892 and based in London. It groups together more than 370 voluntary member companies operating as agents, importers, manufacturers, merchants and sawmillers. It is a member of the (CTI) and the Confederation of British Industry (CBI). TTF members are bound to satisfy specific criteria concerning sustainable sourcing and harvesting before joining the federation. In 2008 the Timber Trade Federation introduced its “Responsible Purchasing Policy” (RPP) and in 2013 adopted the European Union Timber Regulation.
