Charges for Supervision of Installation and Field Efficiency Test paid to Overseas Suppliers are Not Post-importation

The Customs, Excise, and Service Tax Appellate Tribunal (CESTAT) ruled that charges for supervision of installation and field efficiency tests paid to overseas suppliers are not post-importation charges and therefore cannot be included in the assessable value for customs duty purposes. This ruling clarifies that such charges are distinct from the import transaction and should be excluded from the customs valuation, offering relief to importers in terms of reduced duty liabilities.
