HS Code 84079090
Spark-Ignition Reciprocating/Rotary Intl. Combustion Engines, Nes
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 84079090 would be approximately BDT 59,250.00, because the Total Tax Incidence is 59.25% of the assessable value.
What these figures mean
Spark-Ignition Reciprocating/Rotary Intl. Combustion Engines, Nes is classified under HS code 84079090, which sits in heading 8407 (Reciprocating or rotary internal combustion piston engines) of chapter 84 (Nuclear reactors, boilers, machinery and mechanical appliances; parts thereof).
Under the Bangladesh Operative Tariff 2026-2027 this line attracts Customs Duty of 25%, Supplementary Duty of 0%, VAT of 15%, Advance Income Tax of 0%, Regulatory Duty of 5% and Advance Tax of 7.5%. Combined, these produce a Total Tax Incidence of 59.25%, which is the figure to multiply by the assessable value of your consignment.
The assessable value is normally the CIF value of the goods plus landing charges. Duties and taxes are applied in a defined order rather than simply added together, which is why the TTI is not the plain sum of the individual rates.

In February 2026 it was the 3,497th largest of 4,051 tariff lines by assessable value.

How this line compares
Chapter 84 contains 648 tariff lines, averaging 35.59%. At 59.25%, 84079090 sits above that average by 23.66 percentage points. It is the 68th most heavily taxed line in the chapter.
Across the whole Operative Tariff the mean is 61.08%, so this line is cheaper than the typical import by 1.83 points.
Within heading 8407 alone, rates run from 8.58% to 96.1% across 16 lines. Classification inside a single heading can change the bill substantially, so confirm the eight-digit code rather than working from the four-digit heading.
No supplementary duty applies here, which is the normal case — SD is zero on 78% of the tariff. Where it does apply it usually dominates every other component.
