What CE and ETA mean in practice
CE marking and ETA-21/0014 show that the ZTC timber construction system has been assessed against European requirements. This supports compliance in the project but does not guarantee all local approvals. FSC and PEFC are available on request. ISO certification is not claimed. See Hundegger CNC production and CLT panels.
