Export Import SharePoint Content Type using PowerShell
Once all fields of the particular content type is exported and imported, we can Export-Import Content types:

PowerShell Script to Export Content Type:

    #Get the Source Web
    $SourceWeb = Get-SPWeb "http://dev.crescent.com"
 
    #Create Export XML File
    $XMLFile = "C:\SiteContentTypes.xml"
    New-Item $XMLFile -type file -force
  
    #Wrap Content Type Schema XML inside <ContentTypes> Element 
    Add-Content $XMLFile "`n<ContentTypes>"

    #Export All Content types of specific Group to XML file
    $sourceWeb.ContentTypes | ForEach-Object {
        if ($_.Group -eq "Crescent Content Types") 
  {
     #Export Content Types to XML file
            Add-Content $XMLFile $_.SchemaXml
        }
    }
    #Closing Wrapper 
    Add-Content $XMLFile "</ContentTypes>"

    #Dispose the web object
    $SourceWeb.Dispose()

PowerShell Script to Import Content Type:
 [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint") > $null
      #Get the Target Web
      $TargetWeb = Get-SPWeb "http://test.crescent.com"
 
    #Get the Content Type Schema from XML
    $XMLFile = "C:\SiteContentTypes.xml"  
    [xml] $CTypeXML = Get-Content($XMLFile)
  
    #Create Site Content Types
    $CTypeXML.ContentTypes.ContentType | ForEach-Object {

        #Create New Content Type object inheriting from parent
        $SPContentType = New-Object Microsoft.SharePoint.SPContentType ($_.ID,$TargetWeb.ContentTypes,$_.Name)
       
        #Set Content Type description and group
        $SPContentType.Description = $_.Description
        $SPContentType.Group = $_.Group
       
     #Get all field References from the XML
        $_.Fields.Field  | ForEach-Object {
  
   write-host $_.DisplayName
   #Add Fields Reference to the New content type
            if( !$SPContentType.FieldLinks[$_.DisplayName])
            {
                #Create a field link for the Content Type by getting an existing column
                $SPFieldLink = New-Object Microsoft.SharePoint.SPFieldLink ($TargetWeb.Fields[$_.DisplayName])
           
                #Check to see if column is Optional, Required or Hidden
                if ($_.Required -eq "TRUE") {$SPFieldLink.Required = $true}
                if ($_.Hidden -eq "TRUE") {$SPFieldLink.Hidden = $true}
           
                #Add column to Content Type
                $SPContentType.FieldLinks.Add($SPFieldLink)
            }
        }
       
        #Create Content Type on the site and update Content Type object
        $ct = $TargetWeb.ContentTypes.Add($SPContentType)
        $SPContentType.Update()
        write-host "Content type'" $ct.Name "'has been created"
    }

    $TargetWeb.Dispose()
