Import Duty Calculator India

What the formula says

India assesses duty on the assessable value, which is CIF plus a notional landing charge of 1%. Basic customs duty applies to that. A social welfare surcharge of 10% is then charged on the duty itself, and IGST is charged on the total of assessable value plus duty plus surcharge.

Three layers of compounding rather than two, which is why India's effective border rate runs so far above its headline duty rate.

The same thing with real figures

Goods ₹1,500,000, freight ₹200,000, insurance ₹7,900: CIF ₹1,707,900. Adding the 1% landing charge gives an assessable value of ₹1,724,979.

Basic customs duty at 10%: ₹172,498. Social welfare surcharge at 10% of the duty: ₹17,250. IGST at 18% on ₹1,914,727: ₹344,651.

Total ₹534,399 on goods invoiced at ₹1,500,000, 35.6%. The headline duty rate was 10%.

The catch

IGST is recoverable as input tax credit for a GST-registered business, so the unrecoverable cost is the ₹172,498 of duty plus the ₹17,250 surcharge, ₹189,748, or 12.6%. Treating the full 35.6% as cost overstates it by a factor of nearly three.

Some goods also attract compensation cess or specific additional duties on top, and rates for particular commodities have been adjusted frequently. The general structure is stable; the specific rates are not.

Applying it

Separate the recoverable IGST from the unrecoverable duty and surcharge in every landed cost calculation. The two behave completely differently and the combined figure is useful for cash planning and useless for pricing.

Then check whether an FTA rate applies. India has agreements with ASEAN, Japan, Korea, the UAE, Australia and others, and preferential rates under them are frequently a fraction of the general rate.

Schemes worth knowing for Indian importers and exporters

Advance authorisation allows duty-free import of inputs used in goods that will be exported, which removes the duty entirely rather than refunding it later. For a manufacturer exporting a meaningful share of output it is considerably better than paying and claiming back.

The EPCG scheme does the same for capital goods against an export obligation, and duty drawback covers the refund route where the inputs were imported on payment of duty.

The common thread is that India's system offers substantial relief to exporters and comparatively little to pure importers, which is deliberate policy. Any business importing inputs and exporting finished goods should treat these schemes as a first-order part of the cost calculation rather than an afterthought, the difference between using them and not is frequently larger than any sourcing negotiation would deliver.

The other India-specific point worth planning for is clearance time. Indian ports have historically been slower than most, and free storage periods are short relative to the time clearance can take, so demurrage and detention are a routine rather than exceptional cost.

The mitigations are documentary: complete and consistent paperwork submitted before arrival, a customs broker with experience at the specific port, and the Authorised Economic Operator status where volume supports it. AEO accreditation brings faster clearance, reduced examination rates and deferred duty payment, and it is available to smaller importers as well as large ones.

For a business importing regularly into India, the combination of AEO status and an experienced broker frequently saves more in avoided demurrage than the duty planning saves in duty, which is not the order most importers work in.
