A batch of mackerel imported into Lithuania and reloaded for delivery to the customs territory of the Eurasian Economic Union has been found to violate import regulations. The veterinary certificate provided with the cargo indicated a earlier arrival date in Lithuania than the issue date on an Icelandic certificate for fish products exported to the Eurasian Economic Union. This violation has led to the issuance of an order for the cargo's return, banning the import of this batch of mackerel.
