Foreign traders currently have to apply for a license to export logs and peeled masts from Belarus to countries outside of the Eurasian Economic Union. The E.E.U is essentially post-soviet Asian republics along with the Russian federation. So at present if you are a French company based in Belarus who export to the European Union you will need a license.
However the key points in the clause which triggered this policy only applies from the 1st February 2018 until 1st July.
It is unclear if the licenses will continue after this period.
