SELLING TIMBER IN THE EU?
Timberlog also keeps EUDR harvest records and prepares the simplified due diligence statement, with plot geolocation (GeoJSON) and a 5-year reference number vault. It helps you collect data; it is not legal advice, and you submit the statement yourself in the official EU system.
