HS Code 84091000
Parts For Aircraft Engines Of 8407.10
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 84091000 would be approximately BDT 13,580.00, because the Total Tax Incidence is 13.58% of the assessable value.
What these figures mean
Parts For Aircraft Engines Of 8407.10 is classified under HS code 84091000, which sits in heading 8409 (Parts suitable for use solely or principally with the engines of heading no. 8407 or 8408) 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 1%, Supplementary Duty of 0%, VAT of 0%, Advance Income Tax of 5%, Regulatory Duty of 0% and Advance Tax of 7.5%. Combined, these produce a Total Tax Incidence of 13.58%, 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.

Within heading 8409 alone, rates run from 13.58% to 45.88% across 5 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.
