Is GST Registration Mandatory for Import Export Businesses?
Yes, in almost every case. Import and export activity is treated as inter-state supply under GST law, and businesses making inter-state taxable supply are generally required to register regardless of turnover, unlike purely domestic businesses that only need to register after crossing ₹20 lakh or ₹40 lakh. This applies whether you're exporting goods or services, or importing goods for resale or business use.
On the import side, GST registration also matters because Integrated GST (IGST) is charged on goods at the time of import, alongside customs duty, and only a GST-registered importer can claim input tax credit on that IGST. Without a GSTIN, that tax simply becomes a sunk cost rather than a recoverable credit.
How GST Registration Connects to Your Import Export Code (IEC)
The Import Export Code (IEC), issued by the DGFT, is the separate 10-digit code that legally permits a business to import or export goods in and out of India. GST registration and IEC are two different registrations, but they're closely linked in practice: the IEC application process now commonly requires a valid GSTIN and PAN, and customs systems cross-check your IEC against your GST details during shipment clearance.
If you don't already hold an IEC, our team can guide you through both registrations together. Read our complete guide on how to apply for an Import Export Code (IEC) for the full document list and process.
How GST Treats Imports Differently from Exports
| Transaction | GST Treatment |
|---|---|
| Import of goods | IGST charged at customs, based on assessable value plus customs duty; ITC available to a registered importer |
| Import of services | IGST payable by the recipient under reverse charge, where applicable |
| Export of goods | Zero-rated (0%) under LUT, or IGST paid and refunded on export |
| Export of services | Zero-rated (0%) under LUT, subject to meeting the conditions for export of service |
Since exports qualify for zero-rating, most exporters file a Letter of Undertaking rather than paying IGST upfront. See our detailed guide to filing LUT in GST for the exact process.
AD Code Registration and HSN Code Requirements
AD Code Registration
An Authorised Dealer (AD) Code, issued by your bank, must be registered with customs at each port you ship from before shipping bills can be processed. This is separate from GST but is a required next step for any exporter.
Mandatory 8-Digit HSN Codes
Unlike domestic invoices, where 4 or 6-digit HSN codes may suffice depending on turnover, import and export transactions require the full 8-digit HSN code on every shipping bill and invoice.
Use our HSN and SAC code finder to confirm the correct 8-digit code for your traded goods.
