Landed Cost, Customs Duty & GST: The Real Math

A factory quote of $2.10 a unit tells you almost nothing about what that product actually costs you in India. This is the full sum, worked through with real numbers.

Why "factory price" is the wrong number

Ask a first-time importer what a product costs, and you'll usually get the FOB (factory-gate) unit price from the supplier's quote. That number is real, but it's also the smallest piece of what you'll actually pay. By the time a shipment clears Indian customs, freight, duty, IGST, and clearance costs can easily add 25–60% on top of factory price, depending on category and shipping mode — and the ratio is different for every product, which is exactly why importers who don't model it properly get margin surprises after the order is already placed, not before.

The five components of landed cost

ComponentBasisNotes
Product cost (FOB)Unit price × quantityThe number on the supplier's quote.
Freight & insurancePer shipment, allocated per unitVaries by sea/air, LCL/FCL, and route — see our freight comparison.
Basic Customs Duty (BCD)% of (product cost + freight + insurance) = CIF valueRate is entirely HS-code dependent.
IGST% of (CIF value + BCD)Charged on value including duty — see the trap below.
Clearance & handlingFlat/per-shipment feesCHA fees, port handling, any inspection costs.

HS code: the decision that sets your duty

The Harmonized System (HS) code you declare determines your Basic Customs Duty rate, whether any anti-dumping or safeguard duty applies, and which certifications (BIS, WPC, and so on) get triggered. For many products the correct code is unambiguous; for a meaningful minority, a product could reasonably sit under two or three different headings depending on material, function, or intended use — and the duty difference between them can be substantial. Misclassification, even done in good faith, creates real exposure: goods held for reassessment, penalty risk, or a shipment cleared under a code that doesn't survive a physical inspection. Get classification reviewed against your actual product spec before you finalise pricing with a supplier, not after.

A worked example

Take a hypothetical consumer electronics accessory, FOB price $3.00/unit, order of 2,000 units, shipped by sea LCL:

Line itemCalculationAmount (illustrative)
Product cost$3.00 × 2,000$6,000
Freight + insuranceFlat estimate for LCL$650
CIF valueProduct + freight + insurance$6,650
Basic Customs DutyIllustrative rate applied to CIFCategory-dependent
IGSTApplied to (CIF + BCD)Category-dependent
Clearance & handlingCHA + port feesFlat, per shipment

We've left the duty and IGST amounts as "category-dependent" deliberately — publishing a specific percentage here would be more likely to mislead than help, since it changes by HS code and is revised periodically by Indian customs authorities. This is exactly the calculation we run for clients against their actual product and current rates as part of the Logistics & Customs service, rather than something we'd want you relying on a blog post for.

The IGST-on-duty trap

Get this wrong and your whole model is off

IGST is charged on the CIF value plus Basic Customs Duty — not on product cost alone, and not on CIF value alone. Importers who calculate IGST only against their product cost consistently under-budget, sometimes significantly, because they've skipped the compounding step. Always calculate BCD first, add it to CIF value, then apply IGST to that combined figure.

Legitimate ways to reduce landed cost

  • Verify HS classification carefully — the single largest lever, since it's entirely legal and directly sets your duty rate.
  • Consolidate shipments to spread fixed clearance and handling costs across more units.
  • Negotiate FOB terms so you control and can shop freight, rather than accepting a marked-up CIF price you can't audit.
  • Claim IGST input tax credit correctly and promptly if you're a registered, GST-charging business — it's not a cost reduction, but a cash-flow one.

Frequently asked questions

Is customs duty the same for every product? +

No — Basic Customs Duty varies significantly by HS code and can range from single digits to well over 20% depending on category, with some categories carrying additional anti-dumping or safeguard duties on top. There is no single "import duty rate"; it's product-specific.

Do I pay IGST even though I already have GST registration? +

Yes — IGST is charged at the point of import regardless of your GST registration, but registered businesses can typically claim it back as input tax credit, which is why registration matters even if you're not immediately reselling with GST charged.

Can two importers get different duty rates for the exact same product? +

They shouldn't, if classified correctly — but in practice, yes, because HS classification has genuine grey areas and different importers (or their CHAs) sometimes classify similar goods differently. This is exactly why classification review matters before you commit to pricing.

Does the Incoterm I choose affect my landed cost calculation? +

It changes which line items are already included in the quoted price versus billed separately — under FOB you add freight and insurance yourself; under CIF the supplier has already included them (often at a markup you can't audit). Either way, the total landed cost should come out comparable if you're doing the math correctly.
