As of July 1, the EU introduced new customs regulations for exporters from non-EU countries. Customs duties are increasing for countries exporting goods to the EU. Consequently, postal costs from Ukraine to EU countries are increasing.

Specifically for senders from Ukraine

When registering a parcel at the post office, the sender additionally pays a customs fee of up to $10, depending on the destination country of the EU.

This does not apply to UK buyers.
