Customs Duty Calculation Explained explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Customs duty is levied on goods imported into (and some exported from) India. Here is how it is calculated.
Components of import duty
- Basic Customs Duty (BCD) on the assessable value
- Social Welfare Surcharge on the BCD
- IGST on the value plus BCD (creditable as ITC)
- Anti-dumping/safeguard duty where applicable
How it is computed
Duty is calculated on the CIF (Cost + Insurance + Freight) assessable value; BCD is added first, then IGST is charged on the value plus BCD.
Note
Correct HSN classification and valuation are essential to compute the right duty.
