The HS DDS app enables registered HS Timber suppliers and operators to register timber transports. This functionality is currently limited to Romania. The app also integrates the Timflow module, previously available in the Timflow Transporter app. Further features, such as the submission of due diligence statements in accordance with the EU Deforestation Regulation (EUDR), are planned and will be rolled out gradually, including support for additional countries.
