💰 Main Components of Import Charges

Import taxes generally consist of:

1. Assessable Value

2. Basic Customs Duty (BCD)

3. Social Welfare Surcharge (SWS)

4. Integrated GST (IGST)

5. Additional Duties (if applicable)

Let’s understand each component.

---

Step 1: Calculate Assessable Value

The assessable value forms the basis for customs calculations.

Typically calculated as:

CIF Value

CIF stands for:

• Cost
• Insurance
• Freight

Formula:

Assessable Value = Product Cost + Insurance + Freight Charges

Example:

Product Cost = ₹1,00,000

Freight = ₹15,000

Insurance = ₹2,000

Assessable Value = ₹1,17,000

This value becomes the foundation for duty calculations.

---

Step 2: Calculate Basic Customs Duty (BCD)

BCD is applied to the assessable value.

Formula:

BCD = Assessable Value × Duty Rate

Example:

Assessable Value = ₹1,17,000

BCD Rate = 10%

BCD = ₹11,700

---

Step 3: Calculate Social Welfare Surcharge (SWS)

SWS is usually calculated as a percentage of BCD.

Formula:

SWS = BCD × Applicable Rate

Example:

BCD = ₹11,700

SWS Rate = 10%

SWS = ₹1,170

---

Step 4: Calculate Taxable Value for GST

GST is calculated on:

Assessable Value + BCD + SWS

Example:

₹1,17,000 + ₹11,700 + ₹1,170

Taxable Value = ₹1,29,870

---

Step 5: Calculate IGST

IGST is applied to the taxable value.

Formula:

IGST = Taxable Value × GST Rate

Example:

Taxable Value = ₹1,29,870

GST Rate = 18%

IGST = ₹23,376.60
