India Customs Duty Primer | How BCD, SWS & IGST Work on Imports to India

The short version

When goods arrive in India, customs charges stack in a cascade: Basic Customs Duty (BCD), often a small Agriculture Infrastructure & Development Cess (AIDC), a Social Welfare Surcharge (SWS) of 10% on the duty, and then IGST (usually 18%) on the duty-inclusive value. The combined rate ranges from near 0% (phones, laptops) to over 100% (toys). iWishBag pre-calculates the whole cascade into your quote, so there are no surprise charges at delivery.

This primer explains the math and shows real rates.

Who collects what

India's Central Board of Indirect Taxes and Customs (CBIC) assesses customs duty at the border, by the product's HS code. The charge is not a single number — it is a stack:

• BCD — Basic Customs Duty, the headline rate for the product.
• AIDC — Agriculture Infrastructure & Development Cess, applied to certain goods.
• SWS — Social Welfare Surcharge, 10% of the duty (BCD + AIDC).
• IGST — Integrated GST (5%, 18%, or 28%), charged on the duty-inclusive value.

iWishBag handles the classification and pays the whole stack on your behalf.

The duty formula

The cascade runs in order on the assessable (CIF) value:

1. Assessable value = product cost + insurance + freight to India.
2. BCD = assessable value × the product's basic duty rate.
3. AIDC = assessable value × the cess rate (where it applies).
4. SWS = 10% × (BCD + AIDC).
5. IGST = (assessable value + BCD + AIDC + SWS) × the IGST rate (usually 18%).

Each layer builds on the last, which is why the effective rate is higher than the headline BCD alone.

A worked example. A camera costs $400 with $40 freight and $5 insurance:

• Assessable value = $445
• BCD (10%) = $44.50
• AIDC (1%) = $4.45
• SWS (10% of BCD + AIDC) = $4.90
• IGST (18% of $498.85) = $89.79
• Total customs charge = $143.64 (~32% of the assessable value)

Real category rates

The rates below come from iWishBag's own duty dataset, harvested from the CBIC tariff and applied to every India quote (combined duty = BCD + AIDC + SWS; IGST shown separately). The exact figure for any item depends on its precise HS code — these are the representative rates for each category.

Two figures surprise most shoppers: phones and laptops carry 0% basic customs duty (just 18% IGST), while toys carry a 70% BCD — among the highest consumer rates in India — so a toy's landed cost can be more than double its sticker price.

Exemptions and thresholds

• Gifts up to ₹5,000 sent to an individual are generally exempt — but the exemption is strict, frequently scrutinised, and does not apply to commercial-looking shipments.
• Printed books are generally exempt from customs duty and GST.
• No broad low-value de-minimis for ordinary purchases — most imported goods are dutiable from the start.
• Restricted/prohibited goods (certain electronics, drones, some foods) follow separate rules and may need licences.

When a shipment qualifies for the gift exemption, iWishBag flags it; otherwise the full cascade is quoted upfront.

Common questions

How much is customs duty on US purchases shipped to India? It depends on the product's HS code. The charge stacks BCD + AIDC + SWS, then IGST (usually 18%) on the duty-inclusive value. Phones and laptops are effectively 18% (0% BCD); cosmetics and watches land near 49%; toys can exceed 170%. iWishBag quotes the exact figure before you pay.

Why is there duty even though I already paid GST-style tax abroad? Import IGST is India's own tax on the imported value and is separate from any sales tax charged in the origin country. iWishBag includes it in the landed-cost quote.

Are phones really 0% customs duty? The basic customs duty on telephone sets and laptops is 0%; only 18% IGST applies on the duty-inclusive value. That makes electronics among the cheaper categories to import to India.

Why are toys so expensive to import? India levies a 70% basic customs duty on toys to protect domestic manufacturing. With SWS and 18% IGST on top, the effective rate is roughly 170% of the value.

Will I owe extra at delivery? No. iWishBag pre-pays the full duty cascade and bakes it into your quote. The price you approve is the price you pay.

Where do I see the duty in my quote? Itemised in the quote breakdown — product cost, freight, our service fee, and the duty + IGST cascade. Nothing hidden.
