  • Copy of GST Registration containing GSTIN
  • PAN Card of entity for Identification.

Pre-Export Compliance with LUT (Process)

Step 1: Ensure Valid LUT is in Place

  • Action: Verify that your LUT (Form GST RFD-11) is filed and valid for the current financial year. The LUT must be filed before the date of the export invoice.
  • Proof: You should have the Application Reference Number (ARN) generated by the GST portal.

Step 2: Procure Goods at Concessional Rate (0.1% GST)

  • Action: Place the purchase order (P.O.) with your registered domestic supplier.
  • Condition: Provide a declaration to the supplier stating that the goods are being purchased for export and will be exported within 90 days from the date of the supplier’s invoice.
  • Invoice: The supplier issues a Tax Invoice charging GST at the concessional rate of 1% IGST (or 0.05% CGST + 0.05% SGST if Intra-state).
  • Compliance: You must be registered with an Export Promotion Council (EPC) or Commodity Board.

Step 3: Inform Supplier’s Tax Officer

  • Action: Send a copy of the Purchase Order (P.O.) placed at the concessional rate to the Jurisdictional Tax Officer of the Manufacturer/Supplier.

2.  Export Documentation & Shipment

Step 4: Raise the Export Invoice

  • Action: Issue the Export Invoice addressed to your foreign buyer.
  • Mandatory Endorsement: The invoice must clearly state: “Supply meant for Export without payment of IGST under Letter of Undertaking (LUT)” and reference your LUT ARN and date.
  • Note: This invoice is raised at zero-rate (0% IGST).

Step 5: File the Shipping Bill

  • Action: File the Shipping Bill (SB) with Customs through your Custom House Agent (CHA). The SB is the crucial document that proves export.
  • Crucial Linkage: The Shipping Bill must clearly mention:
    • That the export is being made “Without Payment of IGST” (by ticking the LUT/Bond option).
    • The GSTIN and Tax Invoice Number of your domestic Supplier (the one who charged you 0.1% GST) to link the concessional purchase to the final export.

Step 6: Clearance and Shipment

  • Action: Customs clearance, sealing, and shipment of goods.
  • Proof of Shipment: The goods leave India, and the carrier (shipping line/airline) files the Export General Manifest (EGM) or Export Report with Customs.

3.Post-Export Compliance & Refund

Step 7: Proof of Export to Manufacturer/Supplier

  • Action: As discussed, you must immediately provide the following documents to the Manufacturer/Supplier and their Jurisdictional GST Officer:
    • A copy of the Shipping Bill/Bill of Export (You may redact the consignee/importer name for commercial confidentiality, but must show the supplier’s invoice details).
    • Proof of filing the EGM/Export Report.
  • Deadline: You must complete the export (shipment) and provide this proof within 90 days of the supplier’s invoice date.

Step 8: GST Return Filing

  • GSTR-1: File GSTR-1 for the relevant tax period and report the export details (invoice number, value, destination, etc.) in Table 6A (Exports), selecting the “Without Payment of Tax”
  • GSTR-3B: File GSTR-3B, declaring the zero-rated supply in Table 3.1(b) and showing the 1% IGST paid on procurement as eligible Input Tax Credit (ITC) in Table 4(A)(1).

Step 9: Claim ITC Refund

  • Action: After filing GSTR-1 and GSTR-3B, file an online application for refund in Form GST RFD-01 on the GST Portal.
  • Select Category: Choose the category: “Refund of unutilized Input Tax Credit (ITC) on account of zero-rated supplies made without payment of tax.”
  • Processing: The GST officer will process the claim and refund the accumulated ITC (the 0.1% IGST you paid to your supplier, plus any other ITC on services/inputs) to your bank account.

The LUT route, when combined with the 0.1% concessional purchase, is highly beneficial as it ensures minimal cash is blocked in tax payments.
