ICEGATE (Indian Customs Electronic Gateway) is the official e-commerce portal of the Central Board of Indirect Taxes and Customs (CBIC), Government of India, accessible at icegate.gov.in. It is the front-end interface that connects every commercial trade participant in India to the customs network — handling the digital filing of every Bill of Entry for imports under Section 46 of the Customs Act, 1962, every Shipping Bill for exports under Section 50, customs duty payments, document uploads through e-Sanchit, refund and drawback applications, queries to and from customs officers under the Faceless Assessment framework, and integrations with DGFT, GSTN, RBI, and partner government agencies (FSSAI, BIS, Plant Quarantine, Animal Quarantine, Wildlife, Drug Controller, Textile Committee, etc.). Who needs to register: (1) Importers and Exporters — every entity holding an Import Export Code (IEC) from DGFT that intends to file Bills of Entry or Shipping Bills directly (without going through a customs broker). Direct filing reduces costs, gives real-time visibility, and is the norm for organised mid-to-large trade. (2) Customs Brokers (CHAs) — every Customs Broker licensed under the Customs Brokers Licensing Regulations, 2018 who files declarations on behalf of importer / exporter clients. Multi-client filing requires an active ICEGATE registration with proper Power of Attorney linkage. (3) Shipping Lines, NVOCCs, Freight Forwarders, Air Carriers — entities that file Import General Manifest (IGM) under Section 30 and Export General Manifest (EGM) under Section 41; ICEGATE registration as Authorised Carrier required. (4) Container Freight Stations (CFS) / Inland Container Depots (ICD) / Air Freight Stations (AFS) — custodians notified under Section 8 of the Customs Act; ICEGATE registration to file transhipment, de-stuffing, and warehouse declarations. (5) SEZ Units, EOUs, EHTPs, STPs, BTPs — for SEZ Online linkage, ARE-1 filing, zero-rated supply documentation, and integrated trade reporting. (6) Authorised Economic Operators (AEO Tier I, II, III) — for enhanced facilitation, deferred duty payment, direct port delivery, and reduced bank guarantee. (7) Surveyors, Insurers, Banks (AD) — for specific declarations and sample / claim handling. What happens without ICEGATE registration: No Bill of Entry can be filed → no goods can be cleared → consignments stack up at port incurring demurrage and detention charges, eventually facing auction under Section 48 / 49 if not cleared within statutory timelines (typically 30 days). For exports, no Shipping Bill → no Let Export Order (LEO) → no shipment → contract default → reputational damage with overseas buyers. For organised trade, ICEGATE registration is not optional — it is foundational. Cost of registration: ICEGATE registration itself is free (CBIC charges no fee). The supporting cost components are: (a) Class 3 DSC procurement (~₹2,000-4,000 for 2-3 year validity); (b) IEC application from DGFT (~₹500 government fee + professional fees if outsourced); (c) AD Code procurement from AD Bank (typically nominal); (d) professional fees for registration assistance (varies). Registration is typically completed in 7-15 working days for a clean application; complex cases (multi-port, AEO, SEZ) take 3-6 weeks.

These four registrations form the regulatory backbone of every Indian import-export operation, but each serves a distinct purpose, is issued by a different authority, and connects to others in specific ways. (1) IEC (Import Export Code): A 10-digit code issued by the Directorate General of Foreign Trade (DGFT) under the Foreign Trade (Development & Regulation) Act, 1992 and the Foreign Trade Policy. It is the entity-level licence to engage in import / export activity. From 2017 onwards, IEC is identical to the entity's PAN (PAN-IEC system) — meaning your PAN itself becomes your IEC after a one-time DGFT registration. IEC is mandatory for any commercial cross-border trade and is issued for life (no renewal required, but annual updation). (2) ICEGATE Registration: A login on the customs portal (icegate.gov.in) issued by CBIC. ICEGATE is not a separate "code" — it is a system access. To register, you need a valid IEC (which the system validates against DGFT records), PAN, GSTIN, and Class 3 DSC. ICEGATE is the operational interface — every customs declaration flows through it. (3) AD Code (Authorised Dealer Code): A 14-digit code issued by your Authorised Dealer Bank (a bank authorised by RBI under FEMA to deal in foreign exchange). The AD Bank issues an AD Code letter containing the bank's IFSC, the AD Code, and your bank account particulars. The AD Code is then registered separately at each customs port where you intend to import or export — it tells customs which bank to send / receive forex through, and is linked to FEMA compliance. AD Code registration at every port is a one-time event per port. (4) GSTIN (Goods and Services Tax Identification Number): A 15-digit code issued by GSTN (state-wise) under the CGST/SGST/IGST Acts, 2017. GSTIN is your tax identification for indirect taxes — every import attracts IGST, and every export is zero-rated requiring refund or LUT. GSTIN linkage on ICEGATE enables automated IGST refund on exports without separate refund applications. How they connect: Sequence for a new exporter / importer: Step 1 — Obtain PAN (one-time, lifelong). Step 2 — Register for GSTIN (state-wise; mandatory if turnover crosses threshold or for inter-state / export trade). Step 3 — Apply for IEC at DGFT (online; PAN + bank details + KYC; issued in 2-7 days). Step 4 — Open / confirm bank account with an AD Bank; obtain AD Code letter. Step 5 — Register on ICEGATE — the system pulls IEC details from DGFT, GSTIN from GSTN, validates PAN, and binds your DSC. Step 6 — At each customs port of operation, upload AD Code letter through ICEGATE (or directly at the port custom house) — port-wise activation. Step 7 — File first Bill of Entry / Shipping Bill — system performs IEC, GSTIN, AD Code, DSC validations and accepts the filing. Linkage architecture: ICEGATE is the front-end through which all four interact. The backend ICES (Indian Customs EDI System) integrates with: DGFT for IEC validity, licence verification (DGFT-MEIS, RoDTEP, EPCG, Advance Authorisation); GSTN for GSTIN validity, IGST refund routing; RBI / AD Banks for AD Code FEMA reporting; partner agencies for clearance certificates (FSSAI for food, BIS for standards, Plant / Animal Quarantine, Drug Controller). A break in any one — IEC suspended, GSTIN cancelled, AD Code expired, DSC expired, ICEGATE locked — disrupts the entire chain and halts trade. Our practice handles all four registrations as an integrated package for new entrants, and resolves break-points for established operators.

Section 46 of the Customs Act, 1962 requires that the importer of any goods, other than goods intended for transit or transhipment, file a Bill of Entry electronically for home consumption or warehousing before the arrival of the goods at the customs station — the "Pre-Arrival Bill of Entry" (introduced via amendments in 2018-2019 to enable Faceless Assessment and pre-arrival processing). The filing process on ICEGATE: Step 1 — Pre-filing readiness: Active ICEGATE login, valid Class 3 DSC, IEC and AD Code registered for the port, GSTIN validated. Documents ready (or soon to be ready) for e-Sanchit upload — commercial invoice, packing list, Bill of Lading or Air Waybill, certificate of origin (where applicable), licences / authorisations (Advance Authorisation, EPCG, FTA preference), PSI report (where required), import licences for restricted items. Step 2 — Bill of Entry creation: Login → Customs > ICES > Bill of Entry > Create New. The form requires: (a) port code, (b) IEC and importer name, (c) supplier / overseas consignor, (d) shipping line / agent details, (e) Bill of Lading / AWB number, (f) container details (for sea), (g) item-wise description with HSN classification (8-digit Customs Tariff Heading), (h) declared value (CIF) per item, (i) quantity / unit, (j) currency & exchange rate, (k) duty exemption / preference notification claimed, (l) GST registration for IGST application, (m) AEO claim (if applicable). Step 3 — Duty calculation: System auto-computes assessable value (CIF + 1% landing charge + freight if not in invoice), Basic Customs Duty (BCD) per the First Schedule of Customs Tariff Act, Social Welfare Surcharge (10% of BCD), IGST under IGST Act on (assessable value + BCD + SWS), Compensation Cess (where applicable for tobacco / motor vehicles / coal). For preference / exemption claims (e.g., FTA preferential rate, EOU exemption), system applies the reduced rate per notification. Step 4 — e-Sanchit upload: Each supporting document uploaded as a PDF; system generates a Document Reference Number (DRN); DRN tagged to Bill of Entry. Common documents: Commercial Invoice, Packing List, BL / AWB, Certificate of Origin (if FTA preference), Insurance Certificate, Manufacturer's Test Certificate, Catalog / Brochure, Authorisation / Licence. Step 5 — Pre-arrival submission: Bill of Entry submitted with DSC; system assigns Bill of Entry number; status: "Submitted, Awaiting Arrival". Step 6 — Arrival and IGM matching: Once goods physically arrive at the port and the shipping line files Import General Manifest, the system matches BL number / container number — Bill of Entry status moves to "Arrived". Step 7 — RMS routing: Risk Management System decides: Green — direct release without examination or assessment query; Yellow — assessment by NAC under Faceless Assessment; Red — physical examination at the port. Step 8 — Faceless assessment (if Yellow): National Assessment Centre officer raises queries through ICEGATE; importer / CHA responds with documents / clarifications; assessment completed; Out of Charge generated. Step 9 — Duty payment: ICEGATE generates challan; payment through net banking, NEFT, RTGS, or e-payment integrated with authorised banks; payment confirmation triggers next step. Step 10 — Out of Charge (OOC): After successful assessment and payment, the system generates Out of Charge under Section 47, authorising removal of goods from customs custody. Step 11 — Removal & Gate Pass: Goods removed from the port / CFS against Out of Charge; Gate Pass generated; container delivered to importer's premises. Time-bound performance: For imports — Bill of Entry must be filed before end of next day after arrival of vessel / aircraft (Section 46(3)); late filing attracts penalty. Pre-arrival filing is now the norm and avoids any late filing risk. Common errors: HSN misclassification (most disputed area), undervaluation / overvaluation, incorrect FOB / CIF basis, wrong notification number for preference, missing licences (BIS / FSSAI / others). Our practice handles end-to-end Bill of Entry filing, classification advice, valuation defence, faceless assessment query response, and post-clearance audit support.

e-Sanchit (e-Storage and Computerised Handling of Indirect Tax documents) is CBIC's flagship paperless trade facilitation platform integrated with ICEGATE. Pre-2018, importers / exporters had to physically submit hundreds of supporting documents at the customs port — invoices, packing lists, certificates of origin, licences, test reports, PSI reports — leading to massive paper handling, delays, and pilferage / loss risks. e-Sanchit replaced physical submission with electronic upload, enabling fully digital trade flows. How it works: (1) Document scanning / preparation: All supporting documents converted to PDF (resolution typically 200 DPI or higher; size limit per CBIC norms — typically 75 KB to 5 MB per document; multiple PDFs supported per Bill of Entry / Shipping Bill). (2) Login to e-Sanchit: Within ICEGATE, navigate to e-Sanchit module; or upload directly when filing Bill of Entry / Shipping Bill. (3) Document type selection: System provides a master list of document types (Commercial Invoice, Packing List, Bill of Lading, Air Waybill, Certificate of Origin, Insurance Certificate, Catalogue, Test Report, Authorisation, Licence, etc.); user selects the type. (4) Upload: PDF uploaded; system generates a unique Document Reference Number (DRN) for each document; DRN format includes timestamp and identifier. (5) DRN tagging: When filing Bill of Entry / Shipping Bill, the user enters DRNs of relevant documents in the supporting documents section; system links them to the declaration. (6) Customs officer view: Customs officer / NAC officer accesses linked documents through ICEGATE backend during assessment; no physical visit required. (7) Storage: Documents stored on secure CBIC servers; available for retrieval up to retention period (typically 7+ years for compliance); accessible by importer / exporter for own reference. Document categories on e-Sanchit: (a) Commercial documents — invoice, packing list, weight list. (b) Transport documents — Bill of Lading (sea), Air Waybill (air), Lorry Receipt (land). (c) Insurance documents — insurance certificate / policy. (d) Origin documents — Certificate of Origin (Generalised System of Preferences GSP, FTAs like SAFTA / SAARC, ASEAN-India FTA, India-Korea CEPA, India-Japan CEPA, India-UK FTA, etc.). (e) Quality / inspection — pre-shipment inspection certificate, manufacturer's certificate, lab test report. (f) Regulatory licences — DGFT authorisations (Advance Authorisation, EPCG, MEIS, RoDTEP), BIS certificate, FSSAI registration, Drug import licence, Plant Quarantine certificate, Animal Quarantine certificate, Wildlife clearance, CITES, Textile Committee certificate. (g) Banking — Letter of Credit, FIRC (for export receipts). (h) Other — catalogue / brochure, technical specifications, supporting literature. Signing requirements: Documents need to be authenticated as per the originator's standard — Commercial Invoice signed by exporter, Certificate of Origin signed by issuing authority, etc. ICEGATE doesn't require additional signing of e-Sanchit uploads (the Bill of Entry itself is digitally signed with DSC). Errors and amendments: If wrong document uploaded — upload corrected one with new DRN; replace tag in declaration. If document update post-filing needed — submit amendment request through Bill of Entry amendment module; new DRN replaces old. Benefits: Paperless — environmentally clean, no logistics. Speed — instant availability to customs officer; reduces physical visits and waiting. Audit trail — every document timestamped and version-tracked. Cost — eliminates courier costs, paper costs, manpower for physical submission. Storage — long-term digital archive; easy retrieval for past consignments. Common e-Sanchit issues: (a) Wrong document type selection; (b) PDF too large / too small; (c) Image-based PDF (OCR-incompatible) when text-based required; (d) Missing pages; (e) Unreadable scans; (f) DRN expiry (typically valid for limited period after generation if not tagged). Our practice handles e-Sanchit document management as part of every Bill of Entry / Shipping Bill engagement, ensuring document quality, proper tagging, and quick retrieval if queried.

Faceless Assessment is CBIC's flagship reform implemented from 2020 onwards under the broader "Turant Customs" initiative — a paradigm shift where customs assessments are conducted electronically by anonymised officers at National Assessment Centres (NACs) rather than by officers at the port of import. The objective: uniform assessment across India, reduced corruption potential, faster clearance, and accountability through electronic trail. How Faceless Assessment works: Step 1 — Bill of Entry filed at any port through ICEGATE with e-Sanchit documents. Step 2 — RMS routing: Risk Management System decides green (auto-clear), yellow (assessment), or red (examination + assessment). For red / yellow cases, the file is sent for assessment. Step 3 — Anonymised allocation: System randomly allocates the Bill of Entry to one of the National Assessment Centres (located across India in cities like Bengaluru, Chennai, Delhi, Mumbai, Kolkata, Tuticorin, Cochin, etc., each specialising in specific commodity groups / tariff chapters). The importer doesn't know the identity of the assessing officer; the officer doesn't know the importer's port-level history. Step 4 — Officer assessment: The NAC officer reviews the Bill of Entry, e-Sanchit documents, valuation, classification, and exemption claims. Common assessment areas: (a) Tariff classification — is the HSN correctly chosen? (b) Valuation — is the declared value at arm's length? Are related-party adjustments needed? (c) Exemption / preference claims — are notification conditions satisfied? Is Certificate of Origin valid? (d) Restricted goods — is the import licence valid and applicable? (e) Quantity — is the declared quantity matching the documents? Step 5 — Query (if any): If the officer finds issues, a query is raised through ICEGATE — visible to the importer / CHA in their inbox. The query specifies the issue, requested information, and response timeline (typically 7 days, can be extended). Step 6 — Importer / CHA response: The importer / CHA responds through ICEGATE — text response, additional documents (uploaded to e-Sanchit, DRN tagged to query), clarifications. Multiple rounds of queries are possible if the issue is complex. Step 7 — Assessment completion: Officer completes the assessment — accepts declared values / classification, or revises. Revisions generate additional duty demand or refund. Assessment Order is generated. Step 8 — Out of Charge: After payment / acceptance, OOC issued under Section 47. Tips for responding to NAC queries: (1) Read carefully — understand exactly what is being asked; vague responses extend the cycle. (2) Documentary evidence — every claim should be backed by documents; if classifying as a specific HSN, attach catalogue, technical specs, manufacturer literature; if claiming preference, attach valid Certificate of Origin and supporting trade documents. (3) Cite the right notification / regulation — quote the specific notification number and date for any exemption / preference claim; quote the relevant CTH (Customs Tariff Heading) explanatory notes for classification arguments; cite Tribunal / Supreme Court rulings if relevant precedent exists. (4) Respect timelines — respond within the stipulated 7-15 days; long delays risk demurrage and detention costs accumulating, and may invite system escalation. (5) Professional tone — even in pushback, maintain professional tone; the officer is faceless and changes by allocation, but the response remains in the file for any subsequent appeal / scrutiny. (6) Pre-emptive completeness — anticipate likely queries at the time of filing — for example, related party imports invariably attract valuation queries, so pre-attach SVB (Special Valuation Branch) order or Transfer Pricing Report; FTA preference imports invariably attract origin queries, so pre-attach valid CoO with all conditions met. (7) Escalation — if assessment is unjustly adverse, options include: (a) personal hearing request (rarely granted in faceless framework but possible for complex cases); (b) appeal to Commissioner (Appeals) under Section 128; (c) remand request through grievance mechanism. (8) Provisional clearance — under Section 18, goods can be cleared provisionally pending assessment; bond + bank guarantee against differential duty; final assessment within prescribed period. Useful for time-sensitive cargo. Our practice provides faceless assessment query response as a routine service for every Bill of Entry; for complex cases (related party imports, FTA disputes, classification disputes), specialist litigation support is integrated.

Authorised Economic Operator (AEO) is a globally-recognised trade facilitation programme implemented by Indian Customs in line with the World Customs Organisation (WCO) SAFE Framework of Standards. AEO certification recognises an importer / exporter / customs broker / logistics operator as a trusted partner with strong internal controls, compliance history, and security standards — entitled to enhanced facilitation. Three tiers: AEO-T1 (Tier I) — entry-level certification; basic facilitation; eligible after 3+ years of clean import / export history. AEO-T2 (Tier II) — intermediate certification; requires demonstrated internal controls, financial solvency, compliance history; site verification by customs. AEO-T3 (Tier III) — top tier; requires AEO-T2 status for 2+ years, robust security and audit framework, multi-functional integration; highest facilitation. There is also AEO-LO for Logistics Operators (custodians, freight forwarders, port operators) and AEO-CB for Customs Brokers. Eligibility criteria: (a) Established business with 3+ years of operations in international trade. (b) Clean record — no major customs offence in past 3 years; no pending serious investigations. (c) Compliance history — timely filing of returns, payment of duties; no recurring penalty proceedings. (d) Financial solvency — net worth positive; no insolvency proceedings; healthy cash flow. (e) Internal controls — documented procedures for trade documentation, record-keeping, security, and management review. (f) Security standards — physical, IT, personnel, supply chain security per AEO programme requirements. (g) Trade volume — minimum import / export turnover thresholds (varies by tier). Application process: Step 1 — Self-assessment against AEO checklist (provided by CBIC). Step 2 — Internal audit and remediation of gaps. Step 3 — Application filed with AEO Programme Manager (AEOPM) at the appropriate AEO Cell — Mumbai / Delhi / Chennai / Bengaluru / Kolkata. Step 4 — Document review by AEO Cell. Step 5 — Site verification by customs officers (for T2 / T3) — physical inspection of premises, documentation, security systems, IT controls. Step 6 — Recommendation by AEO Cell to AEOPM. Step 7 — Certification issued; valid for 3-5 years; renewable. AEO benefits configurable on ICEGATE: (1) Reduced bank guarantee / security deposit — AEO-T2/T3 entities get materially reduced BG / SD requirements for warehousing, EPCG, Advance Authorisation, transit bonds. (2) Expedited RMS clearance — higher proportion of green / yellow routing; reduced red routing (physical examination); faster overall throughput. (3) Direct Port Delivery (DPD) for imports / Direct Port Entry (DPE) for exports — bypassing CFS de-stuffing; container moved directly from / to importer / exporter premises; saves 3-7 days and ₹15,000-50,000 per container in CFS charges. (4) Deferred duty payment — duty payment deferred to monthly cycle (15-30 days post-clearance) for AEO-T2/T3; cash flow benefit. (5) Self-sealing of containers — exporters can self-seal containers at their premises rather than at port; reduces handling and time. (6) Preferential treatment in faceless assessment — AEO declarations get priority queue, faster query closure. (7) On-site post-clearance audit instead of port-side examination — operational continuity preserved. (8) Mutual Recognition Arrangements (MRAs) — Indian AEOs get reciprocal facilitation in countries with MRAs (e.g., Singapore, USA, EU member states, Japan, China — verify current MRA list); benefits include faster clearance at foreign ports too. (9) Designated Account Manager / Client Relationship Manager at AEO Cell for issue resolution. (10) Protection from suspended / withdrawn licence — AEO status is a strong defence in licence proceedings. Renewal & surveillance: AEO certification is subject to ongoing surveillance — periodic compliance reports, annual review meetings, audit trail maintenance. Renewal applications typically 3-6 months before expiry; renewal subject to continued compliance. Cost-benefit: For mid-to-large traders (₹100+ crore annual import / export turnover), AEO benefits can deliver ₹50 lakh - ₹5 crore annual savings (BG reduction + DPD + deferred duty + faster clearance + reduced CFS costs); the application + maintenance cost (~₹10-25 lakh upfront, ~₹5-10 lakh annually) pays back in months. Our practice handles AEO application support — self-assessment, gap remediation, internal audit, application drafting, site visit support, and ongoing surveillance.

Exports are zero-rated supplies under Section 16 of the IGST Act, 2017 — meaning the export itself does not attract IGST, but the input taxes paid (CGST + SGST + IGST on inputs / input services / capital goods) are refundable to the exporter. There are two routes for IGST refund on exports, and ICEGATE plays a central role in the first (and most common): Route 1 — Exports under payment of IGST: Exporter pays IGST on the export consignment value (effectively re-routing the IGST collected on inputs through the export); claims refund of this paid IGST through the integrated ICEGATE-GSTN system. How it works on ICEGATE: Step 1 — At the time of filing Shipping Bill on ICEGATE, exporter selects "Export under Payment of IGST"; declares the IGST amount (from GSTR-1 export invoice). Step 2 — Shipping Bill processed; "Let Export Order" (LEO) issued under Section 51; goods physically exported; EGM filed by carrier. Step 3 — Exporter files GSTR-1 reporting the export invoice with IGST amount; files GSTR-3B paying the IGST. Step 4 — ICEGATE system matches the Shipping Bill with the GSTR-1 export invoice (matching key: invoice number, IGST amount, GSTIN, port code). On match, ICEGATE auto-processes the refund. Step 5 — Refund credited directly to the exporter's bank account (linked to the AD Code) within 7-30 days of matching, typically without any separate refund application. This is the GSTR-1 + Shipping Bill auto-refund (often called "automated IGST refund" or "Rule 96 refund" under CGST Rules). Common reasons for refund delay / mismatch: (a) Invoice number mismatch between GSTR-1 and Shipping Bill — same invoice number must be used in both; common error: leading zeros, prefix / suffix differences. (b) Port code mismatch — port code declared in GSTR-1 must match the port of export. (c) Exporter GSTIN-IEC mismatch — IEC and GSTIN must be linked correctly on ICEGATE. (d) Refund hold — system flags suspicious patterns (large refunds, new exporter, mismatched invoice values); manual verification triggered. (e) GSTR-3B not filed — IGST must be paid through GSTR-3B before refund processing. Resolution: ICEGATE provides "Refund Status" view; mismatches shown with reason; corrections via GSTR-1 amendment or Shipping Bill amendment. Route 2 — Exports under LUT / Bond (without payment of IGST): Exporter executes Letter of Undertaking (LUT) on GSTN; exports without paying IGST; claims refund of accumulated input tax credit (ITC) on inputs / input services through GSTN refund application (Form GST RFD-01). How it works: Step 1 — Exporter files LUT in Form GST RFD-11 on GSTN; LUT is annual, valid for the financial year. Step 2 — Files Shipping Bill on ICEGATE; selects "Export under LUT without payment of IGST"; LUT reference quoted. Step 3 — Goods exported; LEO; EGM. Step 4 — Exporter files refund application Form GST RFD-01 on GSTN — claims refund of accumulated ITC for the relevant period; supporting documents: Shipping Bill list, GSTR-2A (matched ITC), Statement-3 (formula-based calculation). Step 5 — GST officer scrutinises; approves; refund credited within 60 days. Comparison: Route 1 is simpler, faster (auto-refund), no separate filing; preferred for exporters with regular export volumes and matching GSTR-1 / Shipping Bill discipline. Route 2 useful when input tax credit accumulates faster than output IGST liability (e.g., exporter with all sales as exports; exporter in inverted duty structure). Common errors that block refunds: (i) GSTR-1 not filed for the export period; (ii) GSTR-3B not filed (Route 1); (iii) LUT not filed before export (Route 2 default); (iv) Invoice / port mismatch; (v) AD Code expired; (vi) GSTIN / IEC linkage broken; (vii) Refund bank account not validated on GSTN. Our practice handles end-to-end IGST refund management — return filing, matching, mismatch resolution, refund tracking, and shortage / delay escalation; for entities with large export volumes, we set up a dashboard tracking every Shipping Bill against its IGST refund status.
