Introduction: Why Understanding GST on Imports Matters

Imports are a lifeline for Indian businesses sourcing raw materials, machinery, or goods for resale. Under GST, imports are treated as inter-state supplies, making Integrated GST (IGST) applicable in addition to customs duties and cesses. Proper understanding of GST treatment on imports is critical to avoid delays at customs, manage working capital effectively through Input Tax Credit (ITC), and remain compliant under India’s GST regime in 2025.

This guide covers the legal treatment, calculation methods, step-by-step compliance procedures, required documentation, ITC utilization, customs interface, and practical compliance strategies for imports under GST.

GST Treatment and Legal Basis for Imports

Under the IGST Act, 2017 (Section 5), imports into India are considered inter-state supplies, attracting IGST, which is collected at the time of import along with Basic Customs Duty (BCD) and applicable cesses under the Customs Act.

Key Points:

✅ IGST is levied in addition to customs duties.
✅ Paid IGST can be claimed as Input Tax Credit (ITC) in the importer’s GST returns.
✅ This aligns with GST’s “seamless credit” objective, reducing cascading tax impacts.

IGST Tax Valuation on Imports

IGST on imports is calculated on:

Assessable Value under Customs + Basic Customs Duty (BCD) + Any applicable cess/duty.

Formula:

IGST = (Assessable Value + BCD + Cess) × Applicable IGST Rate

For example:

• Assessable Value: ₹1,00,000
• BCD @10%: ₹10,000
• No cess
• IGST @18%: 18% on ₹1,10,000 = ₹19,800

Total customs duty + IGST = ₹10,000 (BCD) + ₹19,800 (IGST) = ₹29,800

Step-by-Step Compliance Procedure for Imports

1️⃣ Pre-Arrival: Preparatory Steps

✅ Obtain a valid Import Export Code (IEC).
✅ Check product-specific permissions and licenses (e.g., DGFT, BIS).
✅ Perform HS code classification accurately to determine applicable rates.

2️⃣ Arrival: Filing Bill of Entry

✅ File the Bill of Entry (BoE) electronically via the ICEGATE portal upon arrival of goods.
✅ Attach invoices, packing lists, shipment details, and HS codes.
✅ Work with a licensed Customs House Agent (CHA) for error-free compliance and EDI handling.

3️⃣ Payment of Duties and IGST

✅ Pay BCD, applicable cesses, and IGST via the customs portal.
✅ Maintain proof of payment and customs documentation for GST and audit purposes.

4️⃣ Release of Goods

✅ Obtain Customs Release Order (Out of Charge) post clearance.
✅ Track post-clearance audits and risk-based assessments by customs authorities.

Documents Required for Import under GST

To ensure smooth import clearance and GST compliance, maintain:

✅ Import Export Code (IEC) certificate
✅ Commercial invoices and packing lists
✅ Bill of Entry filed on ICEGATE
✅ Shipping bill/airway bill/bill of lading
✅ Payment proofs for customs duties and IGST
✅ Product-specific clearance documents (if applicable)
✅ HS code-based product classification evidence

Input Tax Credit (ITC) and Cash Flow Impact

✅ IGST paid at the time of import can be claimed as ITC in your GST returns, reducing your GST output tax liability.

✅ This mechanism supports working capital management by allowing businesses to recover the IGST paid at customs.

Key Points:

• BCD is not creditable and becomes part of the cost of goods.
• Only IGST and applicable GST cess paid on imports are claimable as ITC.
• Maintain accurate documentation to match ICEGATE records with GST filings (GSTR-2B, GSTR-3B) for seamless ITC utilization.

Role of Customs House Agents (CHA) and EDI

Engaging a competent CHA can simplify compliance by:

✅ Managing HSN classification, Bill of Entry filing, and document preparation.
✅ Handling ICEGATE EDI compliance and customs clearance efficiently.
✅ Ensuring accurate IGST calculations and helping prevent classification disputes.
✅ Assisting with post-clearance audits and customs notices, if any.

Common Mistakes to Avoid While Importing Under GST

❌ Incorrect HS code classification leading to wrong duty/IGST payment.
❌ Incomplete or inaccurate Bill of Entry filings.
❌ Missing or invalid IEC, delaying customs clearance.
❌ Failure to reconcile ICEGATE records with GSTR-2B, resulting in ITC mismatches.
❌ Delay in payment of customs duty and IGST, attracting penalties and demurrage.

Actionable Tips & Checklist for Importers

✅ Pre-check HS codes and applicable IGST rates before import planning.
✅ Maintain clear, organized records of all import documents for 72 months.
✅ Reconcile IGST paid at customs with GSTR-2B monthly to utilize ITC promptly.
✅ Use GST-compliant accounting software to tag imported goods correctly with IGST ITC tracking.
✅ Regularly review import compliance to avoid delays and penalties during post-clearance audits.
✅ Engage with a CHA having expertise in GST-linked customs processes.
