Most exporters of technology products have learned in the past, either through good corporate governance or a knock on the door by their local export control enforcement authority, that encryption is a sensitive subject (pun intended).
Within the European Union, most items incorporating encryption are classified as dual-use goods (when not Military items) and are subject to Export Control.
Within the EU, French authorities extend control of encrypted items beyond the export process to import as well. Cryptographic items can move freely within French territory. However, supplying, importing, or exporting encrypted items are regulated activities.
