An invoice, commercial or pro forma invoice is always required!
Goods always have a value, even if they are only samples.
A commercial invoice is issued if the goods have a commercial value. Up to an invoice value of: € 999.99 an invoice is sufficient. From an invoice value of € 1,000.00 an export declaration is required. The export declaration must be pre-documented, i.e. it must be confirmed in advance by the customs office responsible for the shipper.
Exceptions: an export declaration is always required for shipments to certain countries, such as Norway. The € 999.99 euro limit does not apply!
The declaration can be replaced by the approval as \"authorised shipper\". A proforma invoice is issued if the goods have no commercial value. Example: samples.
