Import List Items with Managed Metadata Field from CSV File

Question

Hello,
I try to import list items from a CSV File. Most of the fields are populating correctly except the Managed Metadata Field. I found multiple examples on how to set Managed Metadata Fields with Powersehll, but unfortunately I couldnt get it running.
The CSV File holds values for the Metadata Column, this value should be checked against the Metadata in the Termstore. If this Term is existent, then it should set the fields value, if it is not existant then it should add the term from the CSV File to the
Term Set in the Term Store. Can anybody give me a tip on how to do this? This is what I have, where Line 4 holds the Metadata:
$Siteurl = "http://siteUrl"
$Rootweb = New-Object Microsoft.Sharepoint.Spsite($Siteurl);
$Webapp = $Rootweb.Webapplication
$listName = "Catalogue"
$listWeb = Get-SPWeb $Siteurl
$list = $listWeb.Lists[$listName]
$pfad1 = "c:\temp\Servers.csv"
$content = import-csv -Delimiter ";" -Path $pfad1 
foreach ($line in $content) {
$newItem = $list.Items.Add()
$newItem["Field 1"] = $line.1
$newItem["Field 2"] = $line.2
$newItem["Field 3"] = $line.3
$newItem["Field 4"] = $line.4
$newItem.Update()
write-host $line.Title imported
Thanks!!

Hi Jimmie,
From your description, when importing list from csv to SharePoint site, you would like to compare if Managed Metadata column exists in term store, and return yes value, if not, add it to term store.
That might need script to achieve. You need to import list at first, then get value from term store, and compare with the list. Change the list field per comparison result, then add new value to term store.
However, there might some workaround to meet your requirement. Not surly understand, so I find some references for you:
If you would like to export Term Set to CSV from SharePoint 2013, then you could compare it:
