Indian HSN Code Lookup

# HSN Code Finder India: CBIC Rules, GST Invoice Mandates & ICEGATE Filing

In India, the Harmonized System of Nomenclature (HSN) code system is administered by the Central Board of Indirect Taxes and Customs (CBIC) for statutory customs tariff assessment and domestic Goods and Services Tax (GST) compliance. Operating under the 8-digit Indian Trade Classification (Harmonized System) — ITC-HS code system — HSN codes govern customs duty assessment on ICEGATE import entries, export documentation, and compulsory tax invoicing under Indian GST law.

Structural Breakdown of India's 8-Digit ITC-HS Code

India appends 2 national tariff item digits to the standard 6-digit WCO Harmonized System structure to form an 8-digit ITC-HS code:

1. Digits 1–2 (Chapter): Chapter 84 (Nuclear Reactors, Boilers, Machinery).
2. Digits 3–4 (Heading): Heading 84.71 (Automatic Data Processing Machines).
3. Digits 5–6 (Subheading): Subheading 8471.30 (Portable Digital Automatic Data Processing Machines).
4. Digits 7–8 (National Tariff Item): Tariff Item 8471.30.10 (Personal Computers / Laptops under Indian Customs Tariff Act 1975).

Compulsory CBIC HSN Reporting Rules on GST Invoices

Under Notification No. 78/2020 – Central Tax issued by the CBIC, taxpayers in India MUST declare HSN codes on all tax invoices based on their Annual Aggregate Turnover (AATO):

| Taxpayer Category / Turnover Threshold | Required HSN Code Length on Domestic Invoices | B2B / B2C Reporting Requirement |

|---|---|---|

| Turnover up to ₹5 Crore INR | 4-Digit HSN Code | Mandatory for B2B tax invoices; optional for B2C invoices |

| Turnover exceeding ₹5 Crore INR | 6-Digit HSN Code | Mandatory for ALL B2B and B2C tax invoices |

| Import & Export Declarations (All Businesses) | 8-Digit ITC-HS Code | Mandatory on all ICEGATE Bills of Entry & Shipping Bills |

Worked Landed Cost & GST Calculation Example for India

Let us model the complete customs duty and IGST calculation for an commercial consignment of electronic components (8-digit HSN 8542.31.00, $10,000 USD CIF value) cleared at Nhava Sheva Port, Mumbai.

Shipment Parameters:

• CIF Invoice Value: $10,000.00 USD
• CBIC Exchange Rate: ₹83.50 INR per 1 USD
• Customs Value (INR): $10,000 × 83.50 = ₹835,000.00 INR
• Basic Customs Duty (BCD): 7.5%
• Social Welfare Surcharge (SWS): 10.0% of BCD (0.75%)
• Integrated GST (IGST Rate): 18.0%

Step-by-Step ICEGATE Customs Calculation:

1. Customs Value (CIF INR): ₹835,000.00 INR
2. Basic Customs Duty (7.5% BCD): ₹835,000 × 7.5% = ₹62,625.00 INR
3. Social Welfare Surcharge (10% SWS): ₹62,625 × 10.0% = ₹6,262.50 INR
4. Taxable Base for Border IGST:

₹835,000 (CIF) + ₹62,625 (BCD) + ₹6,262.50 (SWS) = ₹903,887.50 INR

1. Border IGST (18%): ₹903,887.50 × 18.0% = ₹162,700.00 INR
2. Total ICEGATE Customs Duty Payable:

₹62,625 (BCD) + ₹6,262.50 (SWS) + ₹162,700 (IGST) = ₹231,587.50 INR

1. Input Tax Credit (ITC) Recovery: The ₹162,700.00 IGST is fully reclaimable as ITC by GSTIN-registered businesses.

Frequently Asked Questions

Where can I check the official DGFT import policy for an HSN code?

The Directorate General of Foreign Trade (DGFT) publishes the official ITC-HS Schedule I (Import Policy), detailing whether an 8-digit HSN code is Free, Restricted, or Prohibited.

What is the Service Accounting Code (SAC) in India?

While HSN codes classify physical merchandise, SAC codes (Service Accounting Codes) are 6-digit codes used in India to classify commercial services under GST.

What happens if an incorrect HSN code is declared on a GSTR-1 return?

Mismatched HSN codes cause GSTR-2B reconciliation errors for business clients, delaying Input Tax Credit (ITC) claims and triggering GST demand notices under Section 73/74.

Advanced CBIC Compliance Framework for Indian Importers & Exporters

Essential legal requirements under Indian Customs and GST acts:

• ICEGATE Bill of Entry Validation: Ensure the 8-digit ITC-HS code entered on ICEGATE matches the official Customs Tariff Act Schedule I description to prevent customs query notes (CQ).
• DGFT Import Licensing Flags: Check whether your 8-digit HSN code requires a Restricted Items Import License, BIS Quality Control Order (QCO) compliance, or Compulsory Registration Scheme (CRS) certification.
• Inverted Duty Structure Refunds: Exporters importing raw materials under high HSN duty rates and selling finished goods under lower GST rates can claim refunds of unutilized Input Tax Credit (ITC) under Section 54(3) of the CGST Act.

Complete CBIC Regulatory Framework & ICEGATE Customs Compliance

Key legal guidelines for Indian businesses under Customs and GST Acts:

• Customs Tariff Act 1975 Schedule I: The statutory 8-digit tariff schedule defining Basic Customs Duty (BCD), Preferential Duty rates, and Agriculture Infrastructure and Development Cess (AIDC) for every ITC-HS code.
• CBIC Circulars & Customs Public Notices: Periodically issued by port commissionerates (Nhava Sheva, Delhi ICD, Chennai Port) to clarify classification rulings for ambiguous import commodities.
• GSTR-1 HSN Table 12 Compliance: Taxpayers filing monthly GSTR-1 returns must report total taxable value, total tax amounts (CGST, SGST, IGST), and exact quantity units (UQC) for each declared 4-digit, 6-digit, or 8-digit HSN code.
• Directory General of Foreign Trade (DGFT) Import Licensing: Cross-reference 8-digit HSN codes against DGFT ITC-HS import policy schedules to identify mandatory BIS quality standards, import registration requirements, or import quotas.

Strategic Compliance: Managing Customs Classification Audit Risks

To ensure long-term regulatory compliance across global trade lanes:

• Periodic Classification Reviews: Re-evaluate internal SKU classification master tables annually to incorporate national tariff schedule updates and new WCO classification opinions.
• Customs Audit Preparedness: Maintain complete technical documentation files—including commercial invoices, bill of lading contracts, laboratory material breakdown certificates, and binding rulings—for 5 years post-entry.
• Pre-Import Binding Ruling Petitions: When importing novel, high-value, or multi-component products, file formal binding ruling applications with national customs authorities (CBP in the US, CBIC in India, HMRC in the UK) to legally secure tariff rates prior to shipment dispatch.

Key Compliance Guidelines for Global HS Code Declarations

To ensure seamless customs clearance across international borders:

1. Verify WCO 6-Digit Base: Always ensure your foreign supplier provides the correct WCO 6-digit subheading before converting to local 8-digit or 10-digit national tariff lines.
2. Reconcile Commercial Invoices: Match declared HS codes against commercial invoices, packing lists, and origin certificates prior to electronic customs submission.
3. Audit PGA Regulatory Triggers: Check destination country partner government agency databases (FDA, EPA, USDA, BIS) to submit compulsory permits alongside entry declarations.
