Calculate BCD + Social Welfare Surcharge + IGST — complete landed cost for imports
Why India's Import Duty Calculation Surprises Most Importers
Most people assume customs duty is a single percentage applied to the invoice value. In India, it is actually a chain of three taxes applied sequentially — and each one compounds on top of the previous. IGST is calculated not on the CIF value alone, but on CIF + BCD + SWS combined. This compounding effect means the effective duty rate is always higher than the sum of individual rates suggests. A product with BCD 10% and IGST 18% doesn't cost 28% extra — it costs approximately 32.95% extra because IGST is applied to the already-duty-inflated value. This is not a loophole or error — it's how the Indian customs duty calculation is designed. Understanding this formula prevents budget overruns on every import.
The Exact Calculation Formula (Step by Step)
| Step | Formula | Example (CIF ₹1L, BCD 10%, IGST 18%) |
|---|---|---|
| 1. Assessable Value | CIF value in INR | ₹1,00,000 |
| 2. BCD | AV × BCD% | ₹1,00,000 × 10% = ₹10,000 |
| 3. SWS | BCD × 10% | ₹10,000 × 10% = ₹1,000 |
| 4. IGST Base | AV + BCD + SWS | ₹1,00,000 + ₹10,000 + ₹1,000 = ₹1,11,000 |
| 5. IGST | IGST Base × IGST% | ₹1,11,000 × 18% = ₹19,980 |
| 6. Total Duty | BCD + SWS + IGST | ₹10,000 + ₹1,000 + ₹19,980 = ₹30,980 |
| 7. Landed Cost | CIF + Total Duty | ₹1,00,000 + ₹30,980 = ₹1,30,980 |

IGST ITC — The Business Importer's Advantage
For GST-registered businesses, the IGST paid at customs is not a final cost — it is a cash flow item. You pay it upfront at the port, but you can claim it back as Input Tax Credit (ITC) in your next GST return, typically within 30–60 days. This means the effective customs cost for a business is just BCD + SWS — the IGST is recovered. For a ₹1 lakh import with BCD 10% and IGST 18%, a business pays ₹30,980 total duty but recovers ₹19,980 as ITC, netting only ₹11,000 as permanent cost. Individual importers (personal purchases) cannot claim ITC — they bear the full ₹30,980.
