Hi you need to change the default namespace when you make Xquery, here here is two solutions

SQL

DECLARE @ExportData  XML

SELECT @ExportData =
'<Data xmlns="urn:semi-org:xsd.E142-1.V1005.SubstrateMap">
  <BulkData>
    <EachData Parts="Test1" />
    <EachData Parts="Test2" />
    <EachData Parts="Test3" />
  </BulkData>
</Data>';

 
SELECT @ExportData.exist('
declare namespace ns="urn:semi-org:xsd.E142-1.V1005.SubstrateMap";
 ns:*/ns:BulkData')

 ;WITH XMLNAMESPACES (DEFAULT N'urn:semi-org:xsd.E142-1.V1005.SubstrateMap')  
SELECT @ExportData.exist('*/BulkData')
