Customs Duty on imported goods

Customs Duty on Imported Goods

Customs duty on imports into India is levied under Section 12 of the Customs Act, 1962. The taxable event is crossing India's customs territory; the rate is determined by HS classification under the Customs Tariff Act, 1975. In FY 2026-27, every import bill carries at minimum four layers — BCD, SWS, IGST, and in many cases AIDC — before any exemption notification or FTA concession is factored in. Getting classification wrong, mis-stating transaction value, or failing to satisfy an exemption condition even on a procedural technicality triggers demands under Section 28 that can surface years later with 15% per annum interest and penalties up to 100% of duty.

What Section 12 Charges — and Why the Taxable Event Matters

Section 12(1) is the charging provision. It states that duties of customs shall be levied at such rates as may be specified under the Customs Tariff Act, 1975 (CTA) on goods imported into, or exported from, India. The word levied is critical — duty crystallises at the moment of import, meaning it is determined by the law in force on the date the goods enter India's customs territory, not the date of purchase, contract, or shipment.

This has a practical consequence: if BCD on a tariff heading is revised upward in a mid-year notification between the date your goods sail and the date the vessel enters the port, you pay the higher rate. Importers running long lead-time supply chains — capital goods ordered 90 days out — must monitor notification changes on the CBIC website and build a provisional-to-final-duty buffer into working capital.

Finance Act 2026 did not restructure the charging framework but amended several tariff items in the First Schedule to the CTA. Specific rate revisions apply from 1 February 2026; check the updated First Schedule before accepting a supplier's duty estimate prepared in 2025.

The Complete Duty Stack in FY 2026-27

Most importers focus on BCD and IGST. The full picture is wider:

Basic Customs Duty (BCD)

The primary ad valorem or specific rate under the First Schedule to the CTA. Rates range from zero (e.g., most life-saving drugs under relevant exemption notifications) to 20% or beyond (e.g., certain electronics, automotive components). BCD is not an input tax credit (ITC)-eligible cost for GST purposes — it is a hard cost.

Agriculture Infrastructure and Development Cess (AIDC)

Introduced by the Finance Act 2021, AIDC applies to a defined list of goods (alcoholic beverages, edible oils, gold and silver, petrol, diesel, cotton, and specified others) at rates notified per tariff heading. For goods not in the notified list, AIDC is nil. Capital goods and most industrial inputs fall outside the AIDC net.

Social Welfare Surcharge (SWS)

Levied at 10% of BCD on almost all imports. Note: SWS is calculated on BCD alone, not on the entire duty stack. Where BCD is nil (e.g., goods fully exempt under Notification 50/2017-Cus), SWS is also nil. SWS is not IGST-creditable.

Integrated GST (IGST) — Section 3(7) of the CTA

IGST is charged under Section 3(7) of the Customs Tariff Act at the rate applicable to a like domestic supply of the same goods under the IGST Act, 2017. The IGST base is: Assessable Value + BCD + AIDC + SWS + any other cess. For a registered importer, IGST paid on imports is fully available as ITC in GSTR-3B, making it cash-flow neutral over the credit cycle. For unregistered importers (e.g., individuals, charitable entities not under composition), IGST is a real out-of-pocket cost.

GST Compensation Cess — Section 3(9) of the CTA

Applicable on demerit goods — tobacco, pan masala, coal, luxury cars, aerated drinks — at rates notified under the GST (Compensation to States) Act. Not applicable to ordinary goods.

Anti-Dumping, Countervailing and Safeguard Duties

Imposed by separate notifications on specific goods from specific countries following DGTR investigations. These can add 5–30%+ to the cost and are not IGST-creditable. They must be verified on the CBIC Customs Notification tracker before concluding a sourcing agreement.

Customs Valuation Under Section 14: Getting the Number Right

Customs value — the assessable value (AV) — is the transaction value: the price actually paid or payable for the goods when sold for export to India, adjusted to a CIF (Cost + Insurance + Freight) basis as prescribed under the Customs Valuation (Determination of Value of Imported Goods) Rules, 2007.

The AV computation in practice:

1. Start with the FOB invoice price in foreign currency.
2. Add actual ocean/air freight. If the freight is not separately stated, use actual figures or a notional 20% of FOB (as per Customs Rule 10(2)) for certain cases.
3. Add insurance — actual premium or 1.125% of FOB if not separately stated.
4. Convert to INR at the rate of exchange notified by CBEC for the Bill of Entry date (not the bank rate used in your accounts).
5. Add 1% landing charges (notional addition mandated by Customs Valuation Rules).

The resulting figure is the AV on which BCD and SWS are applied.

When Transaction Value Is Rejected

Customs officers may reject the transaction value — and substitute one via the sequential methods (identical goods → similar goods → deductive → computed → fallback) — in situations including:

• Related-party pricing where the relationship influenced the price
• Circular payments or conditionality on the buyer's resale
• Persistent undervaluation alerts triggered by the Risk Management System (RMS)
• Contemporaneous import data showing significantly higher values for similar goods

If your import is from a related party, proactively document the arm's-length nature of pricing — transfer pricing studies, comparable uncontrolled price data, or cost-plus justifications — before the goods arrive. Post-facto justification during a Customs audit is difficult and expensive.

HS Classification: The Decision That Drives Every Duty Rate

Every duty rate, every exemption notification, every FTA concession flows from the 8-digit HS code assigned to the goods under the First Schedule to the CTA. The General Rules for Interpretation (GRI) — Rules 1 to 6 — are the statutory tool for resolving ambiguous classifications. Rule 1 is paramount: classification is first determined by the Section Notes and Chapter Notes, which are binding law.

Classification Process in Practice

1. Read the goods' technical description — composition, function, end-use.
2. Identify the candidate headings (4-digit level).
3. Apply Section Notes and Chapter Notes to eliminate incorrect headings.
4. Apply GRI 2–6 for composite goods, incomplete items, or sets.
5. Select the 8-digit subheading and verify the BCD rate.

Advance Ruling for certainty: Under Sections 28E to 28H of the Customs Act, an importer can apply to the Customs Authority for Advance Rulings (CAAR) — currently in New Delhi and Mumbai — for a binding ruling on classification, valuation, or origin before the goods are imported. Rulings are typically issued within 90 days. An advance ruling protects you against a short-levy demand for the duration it remains in force.

Mis-classification consequences: A short-levy under Section 28 carries interest at the rate notified under Section 28AA (currently 15% per annum) from the date of short-payment. Penalty under Section 114A is equal to the duty amount (100%) in cases not involving fraud; reducible to 25% if paid within 30 days of the demand order. Where suppression, fraud, or wilful misstatement is alleged, penalty under Section 114AA is up to five times the duty.

Filing the Bill of Entry: Step-by-Step on ICEGATE

The Bill of Entry (BE) is the primary import document filed on ICEGATE (the Indian Customs EDI Gateway at icegate.gov.in). There are three types:

• BE for Home Consumption — goods cleared directly for domestic use
• BE for Warehousing (Into Bond) — goods stored duty-deferred in a customs warehouse
• Ex-Bond BE — clears warehoused goods for home consumption when duty is finally paid

Filing Sequence

1. Obtain IEC (Import Export Code from DGFT) — mandatory before the first shipment.
2. File Prior Bill of Entry on ICEGATE up to 30 days before the expected arrival of vessel/aircraft (for sea/air imports). This enables pre-arrival processing.
3. Enter the 8-digit HS code, country of origin, supplier details, and all charges in the BE.
4. Attach supporting documents digitally: commercial invoice, packing list, bill of lading or airway bill, Certificate of Origin (if claiming FTA rate), insurance certificate.
5. Submit to RMS. Green-channel goods are facilitated automatically; orange-channel requires document verification; red-channel requires physical examination.
6. Pay assessed duty through the Electronic Cash Ledger on ICEGATE. IGST can be paid from the IGST ITC balance or from the electronic cash ledger.
7. Receive the Out of Charge order from the customs officer. Goods can be physically removed only after this.

AEO Advantage: Importers accredited under the Authorised Economic Operator (AEO) programme (AEO-T1, T2, or T3 tier) receive priority processing, dedicated examination queues, and reduced bank guarantee requirements. AEO-T2 and above also qualify for direct port delivery (DPD), eliminating CFS dwell time. AEO accreditation requires a clean compliance history, robust internal controls, and financial solvency — the CBIC application is filed online and involves a site verification. The processing time is typically 60–90 days.

Exemptions Under Section 25(1): Claiming and Protecting Benefits

Section 25(1) of the Customs Act empowers the Central Government to exempt goods from customs duty either absolutely or subject to conditions, by notification in the Official Gazette. The operative mega-exemption notification today is Notification No. 50/2017-Customs (post-GST), which lists hundreds of tariff headings with nil or concessional BCD rates tied to conditions.

How to Correctly Claim an Exemption

1. Identify the notification and condition number. Each exemption entry in Notification 50/2017-Cus is linked to a condition number in the Annexure. Read the condition carefully — most require an end-use declaration, a bond, or a Chartered Accountant certificate.
2. File Form A-1 or the prescribed declaration at the time of filing the BE — not later.
3. Execute the bond with surety (or bank guarantee) where required — typically for end-use-specific exemptions.
4. Monitor post-import obligations — end-use certificates, consumption statements, and periodic reports are due to the jurisdictional Customs Commissionerate.
5. Don't lose documentary evidence. Post-clearance audits under the Customs Audit Regulations can re-examine BE files up to five years after clearance. Gaps in records — missing invoices, unlinked payments — often lead to retrospective demands.

EOU and SEZ imports: Units in Export Oriented Units (EOUs) or Special Economic Zones (SEZs) receive duty-free clearance subject to a bond-cum-legal undertaking (B-17 bond for EOUs) and net foreign exchange (NFE) monitoring. The effective cost benefit is material, but the compliance load — monthly and annual NFE statements, quarterly reports to the Development Commissioner — is substantial.

Project Imports — Heading 9801: Power plants, fertiliser plants, refineries, and certain infrastructure projects can import equipment at a concessional BCD rate under Heading 9801 (currently 5% BCD, as notified). The project must be registered with Customs before imports begin — a post-facto registration is not accepted.

FTAs and CAROTAR 2020: Rules of Origin in Practice

India has operative FTAs with ASEAN, Japan, Korea, UAE, Australia, and EFTA, each offering preferential BCD rates that can be 0–5% against the standard MFN rate of 7.5–20%. However, three conditions must all be satisfied simultaneously:

1. Valid Certificate of Origin (CoO) in the prescribed format (e.g., Form AI for ASEAN, Certificate of Origin for India-UAE CEPA) issued by an authorised body in the exporting country.
2. Rules of Origin (RoO) compliance — the goods must satisfy the product-specific rule: typically a tariff shift, value addition threshold (e.g., 35% regional value content), or a specific process requirement.
3. CAROTAR 2020 compliance — the importer must possess origin information at the time of filing the BE, not just a CoO. Under the Customs (Administration of Rules of Origin under Trade Agreements) Rules, 2020, the importer is required to have details of the supplier's production process, materials used, and the basis of origin determination in their records. CBIC can call for this information during clearance or post-clearance.

Common FTA pitfall: The CoO is valid but the goods were transshipped through a third country without meeting the direct-shipment (non-manipulation) condition. In such cases, the preferential rate is denied and standard BCD applies, often creating a short-levy demand years after clearance.

Worked Example: Full Duty Calculation on Imported Machinery

Scenario: A Pune-based manufacturer imports a CNC milling machine (HS 8457.10.00) from Germany. CIF value: EUR 55,000 at an exchange rate of Rs. 92 per EUR (CBEC notified rate on BE date).

Hard cost (non-recoverable): BCD + SWS = Rs. 3,83,295 + Rs. 38,330 = Rs. 4,21,625 (cannot be claimed as ITC).

IGST (Rs. 9,95,801) is fully available as ITC in GSTR-3B in the month of import, offsetting output GST liability.

If the machine qualified for Project Import (Heading 9801) at 5% BCD:

• BCD = 5% × Rs. 51,10,600 = Rs. 2,55,530
• SWS = Rs. 25,553
• Hard cost = Rs. 2,81,083
• Saving vs. standard rate: Rs. 1,40,542 — purely from correct tariff classification and prior project registration. The registration paperwork costs a fraction of this.

Common Mistakes That Trigger Section 28 Demands

1. Adopting the Supplier's HS Code Without Verification

Overseas suppliers classify under their home country's tariff schedule. India's HS codes at the 8-digit level differ in scope and rate. Accepting the supplier's classification without independent verification is the single most common cause of customs demands in manufacturing importers.

2. Ignoring RoO Documentation Under CAROTAR

Filing an FTA-rate BE with a valid CoO but without maintaining the underlying origin evidence is a time-bomb. CBIC post-clearance audit teams routinely ask for CAROTAR records 12–24 months after clearance. If records are incomplete, the preferential duty is recovered with interest.

3. Treating Related-Party Invoices as Automatically Acceptable

Imports from group companies at transfer-price values face heightened scrutiny. Customs valuation and transfer pricing operate under different rules — an arm's-length price under Income Tax Rule 10 may still be challenged under Customs Valuation Rule 3(3). Maintain a separate customs valuation study for significant related-party import streams.

4. Missing the Prior Bill of Entry Window

ICEGATE allows Prior BE filing up to 30 days before vessel arrival. Missing this window delays processing and can push clearance into overtime or demurrage territory. On high-volume vessels, red-channel examination queues can mean 5–7 additional days — at Rs. 5,000–15,000 per day in port demurrage for a 20-foot container.

5. Not Reconciling GSTR-2B with Customs BOE Data

IGST paid on imports flows into GSTR-2B via ICEGATE data integration. Importers sometimes claim IGST ITC on the basis of the Bill of Entry without verifying whether it has appeared in GSTR-2B. Mismatch triggers GST scrutiny notices under Section 61 of the CGST Act. Reconcile your BOE register against GSTR-2B monthly.

6. Letting Exemption Conditions Lapse

An end-use bond executed at import time requires submission of consumption/utilisation certificates within stipulated periods — typically one to two years. Failure to submit converts the bonded duty liability into an outright demand, recovered with interest from the date of import.

Dispute Resolution: Section 28 to CESTAT

When Customs raises a demand:

1. Section 28 notice (Show Cause Notice): The department must issue a SCN within two years of the relevant date for normal cases, or five years where fraud, suppression, or wilful misstatement is alleged. Respond within the time prescribed in the SCN — typically 30 days.

1. Personal Hearing: Request one; it is a right. File a detailed written reply addressing each allegation with supporting documents.

1. Order-in-Original: The Adjudicating Authority passes the order. If adverse, appeal lies before the Commissioner (Appeals) under Section 128 within 60 days of the order.

1. CESTAT: Further appeal to the Customs, Excise and Service Tax Appellate Tribunal within three months of the Commissioner (Appeals) order. CESTAT decisions on pure questions of law or mixed questions are further appealable to the respective High Court under Section 130, and to the Supreme Court under Section 130E.

1. CAAR Advance Ruling: For forward-looking certainty, file for an advance ruling on classification, valuation, or origin before a new product line's first import. CAAR rulings are binding on both the importer and the department for the applicant's imports, and effectively shield a confirmed interpretation from challenge.

Key Takeaways

• The taxable event is the date of import, not the date of contract or invoice. Monitor mid-year tariff notification changes — especially during the February budget cycle — if your goods are in transit.
• Your effective hard cost is BCD + SWS, since IGST is ITC-recoverable for registered importers. Optimising BCD through correct classification and legitimate exemption claims directly improves landed cost.
• Customs valuation disputes are the largest source of customs litigation in India. Document the arm's-length basis of all related-party import pricing before goods move.
• FTA benefits are conditional, not automatic. A valid CoO is necessary but not sufficient — you must also maintain CAROTAR origin evidence and satisfy direct-shipment conditions.
• File Prior Bill of Entry on ICEGATE to enable pre-arrival processing. AEO accreditation compresses this further, eliminating CFS dwell time for AEO-T2 and above.
• Section 28 demands can surface up to five years post-import in fraud cases. Maintain BOE files, CoOs, end-use certificates, and CAROTAR records for at least six years.
• When doubt exists on classification or origin, obtain a CAAR Advance Ruling before the first shipment — it binds the department and eliminates the re-assessment risk for the entire product lifecycle.
