Customs duty calculator — India import chain

Duty is not a flat “20% on product price.” Indian air imports typically stack BCD on CIF, SWS on BCD, then IGST on the duty-paid value. Here is the exact chain our engine uses.

The duty chain we model

1

CIF

Goods value + international freight (our door freight line feeding the tax base).

2

BCD

Basic Customs Duty = CIF × duty%.

3

SWS

Social welfare surcharge = BCD × 10%.

4

IGST

IGST 18% on (CIF + BCD + SWS). Plus 18% GST on service/handling lines separately.

Formulas (rate-engine.js)

CIF=goodsValue+freight
BCD=CIF×dutyPct / 100
SWS=BCD×0.10
IGST=(CIF + BCD + SWS)×0.18
Service GST=handling×0.18

Category dropdowns seed dutyPct (e.g. general ~10%, accessories ~20%, footwear ~35%, toys ~70%). Override with the duty field when you know a better HS-linked rate.

Clearance fee tiers

Independent of BCD: ₹1,000 clearance when goods value is under ₹1 lakh; ₹3,000 at or above. Ops and zone adds stack on top for the handling total.

What the estimate cannot promise

  • Anti-dumping / countervailing duties
  • BIS / FSSAI / CDSCO conditions
  • CBIC exchange rate on filing day
  • Value re-determination by assessing officer

That is why the site labels duty as illustrative while freight from the card is firm. Confirm HS code with us before you lock a large PO.

FAQ

Is BCD always 10%?
No. Category defaults in the calculator are indicative averages. Real BCD is set by the 8-digit HS code — two products in one “category” can differ.
What is SWS?
Social Welfare Surcharge — 10% of the BCD amount in our engine (matching the standard import stack we implement).
