Unfortunately, the problem of the incorrect customs declaration documents (CN23) could not be solved by DHL yet. We are currently working intensively on an alternative solution, which is expected to be available on Monday, June 8th, 2020.
Despite our information, the electronic data transfer to customs is not sufficient and most of the shipments are currently rejected by customs.
As an interim solution, we recommend using the customs documents from DHL and filling them in manually (https://www.dhl.de/content/dam/images/pdf/dhl-zollinhaltserklaerung-cn23-032020.pdf
), or withhold your dutiable shipments until Monday.
Please excuse the inconvenience this may cause.
