DUP FAQ
Questions users ask after seeing this error
What does DUP mean?
The same document or transaction appears to have been submitted more than once.
Can I refile after fixing this error?
Refiling depends on the transaction. First confirm whether the original submission failed, is pending, or already created an acknowledgement.
Who should resolve this issue?
Filing User / CHA / Importer / Exporter should review the relevant source record or system step.
Is this always an ICEGATE system problem?
No. The cause may be source data, a carrier filing, GST or bank validation, DSC setup, user access, Customs processing, or the ICEGATE service.
Should I contact Customs?
Contact Customs when the record is waiting for officer action, assessment, approval, or a customs query. Technical and source-data issues should go to the responsible team first.
How long does resolution usually take?
There is no fixed time. A local data or DSC issue may be corrected quickly, while carrier, bank, GST, or Customs processing depends on the responsible organisation.
