When a postal item is detained, what actions are taken by Lithuania Post?

When a postal item is detained, Lithuania Post sends a notice (its example is available here) to the addressee (to the address indicated on the postal item) requesting him/her to present information on articles/goods contained in the postal item. The items are held at the Mail Sorting Department until submission of additional data and documents. International express mail items are stored 15 days, and the retention period for the rest of items (registered, non-registered) is 30 days. If Lithuania Post’s declarants do not receive additional information, payable taxes will be calculated on the basis of comparative values.
