An import duty calculator India resolves the question every importer eventually faces: what will this shipment actually cost to bring into the country? The answer is not simply the product price plus shipping. It is a layered calculation involving Basic Customs Duty, Social Welfare Surcharge, and Integrated Goods and Services Tax, each applied on a different base. Get one component wrong and your landed cost estimate can be off by thousands of rupees. This guide walks through the exact formula, the 2026 Budget changes, and the practical details that determine what you pay at the port.
Import duty is the tax Indian Customs charges on goods entering India from foreign countries. It is governed by the Customs Act, 1962 and administered by the Central Board of Indirect Taxes and Customs under the Ministry of Finance. The duty applies to the CIF value of the goods — Cost, Insurance, and Freight — converted to Indian rupees at the customs exchange rate[reference:0].
For a business importing raw materials or finished goods, import duty is a direct cost that affects pricing, margin, and competitiveness. For an individual bringing in personal effects or receiving an international shipment, it determines whether the purchase still makes financial sense. Unlike income tax or GST on domestic transactions, customs duty is assessed at the border and must be paid before the goods are released. There is no deferral unless you qualify as an Authorised Economic Operator with an approved duty deferral facility[reference:1].
The structure of import duty has three primary layers. Each layer applies on a different base, which is why the effective burden is always higher than the headline BCD rate. Understanding the stacking order is the first step to calculating accurately.
Every commercial import into India is assessed on the same fundamental structure. The components stack in a fixed sequence, and changing one changes the base for the next.
| Component | Full Name | Calculation Base | Refundable / Creditable |
|---|---|---|---|
| BCD | Basic Customs Duty | Assessable Value (CIF × 1.01) | No |
| SWS | Social Welfare Surcharge | 10% of BCD (normally) | No |
| IGST | Integrated Goods and Services Tax | Assessable Value + BCD + SWS | Yes, for GST-registered importers |
| AIDC | Agriculture Infrastructure and Development Cess | On selected goods | No |
| ADD / CVD | Anti-Dumping Duty / Countervailing Duty | CIF value, product or origin specific | No |
BCD is the primary duty. Its rate depends entirely on the product's classification under the Customs Tariff Act, 1975. Rates range from zero on lifesaving drugs and certain raw materials to over 100% on some agricultural products and luxury items. The 8-digit HSN code determines which rate applies. A single-digit error in classification can change the duty by thousands of rupees[reference:2].
SWS is a surcharge introduced in 2018 to fund social welfare programmes. It is normally 10% of the BCD amount. When BCD is zero, SWS is zero. When BCD is high, SWS adds a meaningful layer. The government has exempted SWS on certain goods, including some fertilisers, lifesaving drugs, and specific raw materials. For gold and silver, the SWS and AIDC rates were revised separately in May 2026, taking the overall duty on gold to 15%[reference:3].
IGST is the goods and services tax applied to imports. It ensures imported goods are taxed at the same rate as similar domestic products. The IGST rate mirrors the GST slab for that product — 0%, 5%, 12%, 18%, or 28%. For most industrial goods and consumer electronics, 18% is standard. For GST-registered importers, IGST is recoverable as input tax credit. For individuals importing for personal use, it is a permanent cost[reference:4].
The calculation follows a fixed sequence. Each step feeds into the next.
The 1.01 multiplier on CIF is the landing charge — it accounts for the cost of unloading and handling at the port. It is a standard addition to the CIF value for customs valuation purposes. If your product attracts AIDC, that is added before SWS is calculated. If anti-dumping or countervailing duty applies, it stacks on top and is never refundable.
Here is what each step looks like in practice with a simple example. Suppose you import goods with a CIF value of ₹1,00,000. The BCD rate is 10% and the IGST rate is 18%. No AIDC or ADD applies.
The effective duty burden on this shipment is 31.29% of the CIF value. For a GST-registered business, the IGST component of ₹20,179.80 is recoverable as input tax credit, reducing the sunk cost to ₹11,110. For an individual importer, the entire amount is a cost[reference:5].

The Union Budget 2026 reduced the tariff rate on all dutiable goods imported for personal use from 20% to 10%, effective 1 April 2026[reference:6]. This is a significant change for individuals bringing in electronics, appliances, and other personal effects from abroad. The following example shows the difference.
Suppose you import an air conditioner with a CIF value of ₹40,000. The applicable HSN code is 84151020, with a BCD rate that was previously 20% for personal imports and is now 10%. The IGST rate on air conditioners is 28%.
Under the old 20% rate:
Under the new 10% rate:
The saving is ₹5,520 on this single shipment. For frequent travellers or individuals importing high-value electronics, the revised rate materially changes the landed cost calculation[reference:7]. Note that the example above uses the simplified SWS calculation — SWS is always 10% of BCD, not of the IGST-inclusive value. Some older references incorrectly show SWS being calculated after IGST is added. The correct sequence is BCD first, then SWS on BCD, then IGST on the sum of AV, BCD, and SWS.
The Union Budget 2026-27 introduced several changes that affect importers across categories. The most significant for individuals was the reduction of personal import duty from 20% to 10%. For businesses, the budget focused on tariff rationalisation and trade facilitation.
A major reform was the absorption of numerous notification-based exemptions and concessional rates directly into the Customs Tariff from 1 May 2026[reference:8]. This means the duty rate you see in the tariff schedule is now closer to the actual rate you pay, reducing the need to cross-reference multiple notifications. For importers who previously relied on specific exemption notifications, the change may alter the effective duty calculation.
The budget also enhanced the duty deferral period for Tier 2 and Tier 3 Authorised Economic Operators from 15 days to 30 days, and extended the same facility to eligible manufacturer-importers. The validity of advance rulings was extended from three years to five years[reference:9]. These measures reduce working capital pressure and compliance uncertainty for regular importers.
On the specific rate side, BCD on more than 40 chemicals and plastic raw materials was reduced to zero until 30 June 2026, a measure aimed at lowering input costs for manufacturing[reference:10]. Basic Customs Duty was exempted on 17 drugs and medicines, particularly for cancer patients, and seven more rare diseases were added to the list of conditions eligible for duty-free personal imports of drugs and food for special medical purposes[reference:11].
For gold and silver, the government revised SWS and AIDC rates in May 2026, effectively raising the overall import duty on the precious metals to 15%. The basic customs duty itself was not changed; the increase came from higher surcharge and cess components[reference:12]. This matters for jewellers, bullion traders, and individuals importing precious metals.
The calculation formula is the same, but the rates and treatment differ. Personal imports are goods brought in by an individual for personal use, not for resale or commercial purposes. Commercial imports are goods imported by a business for trade, manufacturing, or resale.
Personal imports attract the reduced 10% tariff rate under Budget 2026, subject to the duty-free baggage allowance. Commercial imports attract the standard BCD rate for the product's HSN code, which varies from zero to over 100%. A commercial importer must also have an Import Export Code, file a bill of entry through ICEGATE, and comply with any product-specific regulations such as BIS certification or FSSAI clearance.
The distinction between personal and commercial is not simply a matter of quantity. Customs officers assess the nature of the goods, the frequency of imports, and the declared purpose. Importing five identical smartphones is unlikely to be accepted as personal use. Importing a single laptop for personal use is straightforward. If you are unsure how your shipment will be classified, the safest approach is to declare it accurately and be prepared to justify the personal-use claim.
India has free trade agreements with several countries and regions, including ASEAN, Japan, South Korea, the UAE, and Australia. These agreements can reduce the BCD rate to zero or a concessional rate for eligible products, provided the goods meet the rules of origin criteria and you present a valid Certificate of Origin[reference:13].
The rules of origin determine whether a product qualifies for preferential treatment based on where it was substantially transformed, not simply where it was shipped from. A product manufactured in a non-FTA country and routed through an FTA partner does not qualify. Customs checks origin declarations strictly, and incorrect claims can result in penalties and denial of the preferential rate.
Even when BCD is reduced to zero under an FTA, SWS is zero (since it is calculated on BCD), but IGST still applies at the standard rate for the product. The saving is real but it applies only to the BCD component. For a product with a 10% BCD rate and 18% IGST, an FTA that reduces BCD to zero eliminates the BCD and SWS, but the IGST remains payable on the assessable value.
If you import regularly from an FTA partner, model the landed cost both with and without the preferential rate. The Certificate of Origin requirement adds documentation effort, and the supplier must be able to provide it. For low-value shipments, the administrative cost may outweigh the duty saving.
Most import duty errors fall into a few predictable categories. Knowing them in advance saves time, money, and customs disputes.
Using the wrong HSN code. This is the single most expensive mistake. The HSN code determines the BCD rate, the IGST rate, and any applicable AIDC or trade remedy duty. A product classified under the wrong code can attract a duty rate several times higher than the correct one. Always confirm the 8-digit code using the CBIC tariff schedule or a reliable HSN finder tool. For high-value shipments, a customs house agent can verify the classification before filing.
Forgetting the 1.01 multiplier. The assessable value is not simply the CIF value. It is CIF × 1.01. The 1% landing charge is a standard addition. If you calculate duty on the raw CIF value, you will understate the duty by 1% of the CIF, which on a ₹10 lakh shipment is ₹1,000 before the compounding effect.
Calculating SWS on the wrong base. SWS is 10% of BCD, not 10% of the assessable value or the IGST-inclusive total. Some online guides and older references show SWS being calculated after IGST. That is incorrect. The correct sequence is BCD first, SWS on BCD, then IGST on the sum of AV, BCD, and SWS.
Assuming IGST is always refundable. IGST is refundable as input tax credit only for GST-registered importers using the goods for business purposes. Individuals importing for personal use cannot claim it. Businesses that are not registered under GST also cannot claim it. For them, IGST is a permanent cost.
Ignoring anti-dumping and countervailing duty. These trade remedy duties stack on top of BCD, SWS, and IGST. They are product-specific and origin-specific. A product from one country may attract anti-dumping duty while the same product from another country does not. Always check the latest CBIC notifications for your product and origin before finalising your cost estimate.
Under-declaring value. Customs has the power to reject the declared value under Section 14 of the Customs Act, 1962 and determine the value based on contemporaneous import data. Penalties include confiscation, fines up to the value of the goods, and prosecution in serious cases. The short-term saving from under-declaration is never worth the risk.
For importers who need to verify the percentage components of their duty calculation — such as the effective burden as a percentage of CIF, or the saving from a preferential rate — the percentage calculator on Calculator200.com provides a quick cross-check. The full range of finance and general calculators is available on the general calculator index and the finance calculator index.
The formula is: Assessable Value = CIF × 1.01. BCD = Assessable Value × BCD rate. SWS = BCD × 10%. IGST = (Assessable Value + BCD + SWS) × IGST rate. Total duty = BCD + SWS + IGST. You need the product's 8-digit HSN code and its CIF value in rupees to start.
SWS is normally 10% of the Basic Customs Duty amount. However, the government has exempted SWS on certain goods such as lifesaving drugs, some fertilisers, and specific raw materials. For gold and silver, the SWS and AIDC rates were revised separately in May 2026. Always check the latest CBIC notification for your specific product.
Yes, if you are a GST-registered importer and the goods are used for business purposes, the IGST paid on imports is available as input tax credit. BCD and SWS are not creditable and become a permanent cost. For non-GST-registered individuals importing for personal use, the entire duty including IGST is a sunk cost.
The Union Budget 2026 reduced the tariff rate on all dutiable goods imported for personal use from 20% to 10%, effective 1 April 2026. The duty-free baggage allowance for international travellers was also raised to ₹75,000. This applies to goods brought in for personal consumption, not commercial shipments.
BCD is a customs duty levied under the Customs Tariff Act, 1975. IGST is a goods and services tax levied under the GST framework. BCD is calculated on the assessable value. IGST is calculated on the assessable value plus BCD plus SWS. BCD is never refundable as credit. IGST is refundable as input tax credit for registered businesses.
Use the CBIC tariff schedule at cbic.gov.in or a reliable HSN finder tool. Enter your product description and the tool suggests the 8-digit Indian tariff classification. A single-digit error can change your duty liability by thousands of rupees. For high-value shipments, always confirm the HSN code with a licensed customs house agent before filing the bill of entry.
Often yes, but only if the goods meet the rules of origin criteria and you have a valid Certificate of Origin. India has FTAs with ASEAN, Japan, South Korea, UAE, Australia, and others. These agreements can reduce the BCD rate to zero or a concessional rate for eligible products. However, IGST and SWS still apply in most cases.
Indian Customs has the power to reject the declared value under Section 14 of the Customs Act, 1962 and determine the value based on contemporaneous import data or other evidence. Penalties can include confiscation of goods, a fine up to the value of the goods, and prosecution in serious cases. Always declare the correct CIF value and maintain supporting invoices.
In sum, an import duty calculator India is only as reliable as the inputs you feed into it. The HSN code must be correct, the CIF value must reflect the true cost of goods, insurance, and freight, and the duty components must be stacked in the right order. Budget 2026 changed the landscape for personal imports with the reduction to 10%, and the broader tariff rationalisation has simplified the rate structure for many products. Whether you are a business modelling landed cost for a commercial shipment, an individual checking what you will pay on an international purchase, or a customs broker verifying an assessment, the formula remains the same: assessable value first, BCD second, SWS on BCD, and IGST on the combined total. Use the percentage calculator to verify each component, and treat the output as what it is: a precise estimate that eliminates the guesswork from cross-border purchasing.
