Import Duty India Explained: BCD + SWS + IGST + Cess (Worked Example)

Import duty isn't one number — it's a four-component stack with each piece calculated against a different base. Below: how CIF turns into landed cost, where the IGST credit comes back, and why the “effective tax” on imports is lower than it looks.

First-time importers see the BCD rate (say 10%) on their HSN code, multiply it by their invoice value, and assume that's the duty. Then they get the Bill of Entry from their CHA and discover the actual duty was 30% — three times their estimate. The reason: BCD is just one of four taxes, each layered on top of the previous. Get the order right and the math is straightforward.

The four-component duty stack

BCD (Basic Customs Duty) — set per HSN code in the First Schedule to the Customs Tariff Act, 1975. Computed as a percentage of CIF value.
SWS (Social Welfare Surcharge) — fixed at 10% of BCD by the Finance Act 2018. Replaced the earlier 3% Education Cess.
IGST (Integrated GST) — matches the GST rate of the same goods sold domestically. Applied to (CIF + BCD + SWS), not on CIF alone.
Compensation Cess — top-up on specific HSNs (luxury cars, tobacco, aerated drinks, coal). Calculated on the same base as IGST.

Plus, on specific consignments: Anti-Dumping Duty (product + country specific, like solar cells from China) and Safeguard Duty (rarely active). Always check the latest CBIC notification.

CIF: the assessable value

Customs uses CIF (Cost + Insurance + Freight) as the base for BCD. CIF is invoice value + freight to Indian port + insurance. Customs adds a deemed 1% landing charge to declared CIF as a notional handling cost.

If your invoice is FOB (Free On Board — excluding freight), multiply by ~1.10–1.15 to approximate CIF for budgeting. For exact CIF, add actual freight quote + insurance (typically 0.5–2% of cargo value).

Worked example: ₹1,00,000 CIF, BCD 10%, IGST 18%, no Cess

Component	Formula	Amount (₹)
CIF	user input	1,00,000
BCD	100,000 × 10%	10,000
SWS	10,000 × 10%	1,000
Assessable for IGST	CIF + BCD + SWS	1,11,000
IGST	111,000 × 18%	19,980
Total Duty	BCD + SWS + IGST	30,980
Landed Cost	CIF + Total Duty	1,30,980

The IGST “refund”: why effective tax is lower

Here's the thing nobody mentions: IGST on imports is creditable as input tax credit for GST-registered importers. Of the ₹30,980 total duty above, ₹19,980 (the IGST) flows back as ITC against your output GST liability. Net sunk cost: BCD + SWS = ₹11,000.

For unregistered importers (individuals importing for personal use, small traders below the GST threshold), IGST is a real cost. Do your own math accordingly.

Preferential rates (FTA imports)

India has Free Trade Agreements with ASEAN, SAARC, Japan, Korea, UAE, Australia and others. Imports from FTA-partner countries can claim a preferential BCD rate — often 0% or near-zero — if accompanied by a Certificate of Origin (CoO) issued by an authorised body in the exporting country.

Without a valid CoO, customs applies the standard rate. Don't budget on the preferential rate until you've confirmed your supplier can provide one.

Anti-Dumping Duty (ADD)

ADD is a punitive duty on specific HSN + country combinations where Indian regulators determined dumping below fair price. Examples that have been active recently: solar cells from China, certain steel pipes from Korea, melamine from Saudi Arabia, ophthalmic lenses from various countries.

ADD can be 5-100%+ of the assessable value. Check DGTR (Directorate General of Trade Remedies) notifications for your HSN + country before signing a purchase order. A profitable trade can become a money-loser if ADD activates after you've booked the cargo.

Practical workflow for first-time importers

Find the HSN code for your product (use HSN Lookup or the WTO HS database).
Check standard BCD rate via Import Duty Calculator.
Check if FTA preferential rate applies for the country of origin → verify CoO availability.
Find the IGST rate matching the product's GST classification (most goods are 18%).
Check Compensation Cess for HSNs in luxury/sin categories.
Check ADD / Safeguard for your HSN + country at DGTR.
Plug CIF into the calculator → get total duty.
Add 1-2% buffer for clearing house agent fees, port handling, demurrage.

Frequently asked

Why is total duty 30% on a 10% BCD? Because of cascading: BCD is on CIF (10%), SWS adds another ~1% on top of BCD, IGST is 18% but applied to a now-larger base (CIF+BCD+SWS). Sum hits ~30% effective tax on CIF.

Is the duty on FOB or CIF? CIF — always. Customs adds a 1% landing charge to declared CIF and uses that as assessable.

Does GST registration help? Yes — for IGST recovery as input credit. If you import frequently, GST registration pays for itself within a few shipments.
