HS Code 84121090
Reaction Engines (Excl. Turbo-Jet/Aircraft)
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 84121090 would be approximately BDT 27,500.00, because the Total Tax Incidence is 27.5% of the assessable value.
What these figures mean
Reaction Engines (Excl. Turbo-Jet/Aircraft) is classified under HS code 84121090, which sits in heading 8412 (Engines and motors; n.e.c. (e.g. reaction engines, hydraulic power engines, pneumatic power 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 0%, Supplementary Duty of 0%, VAT of 15%, Advance Income Tax of 5%, Regulatory Duty of 0% and Advance Tax of 7.5%. Combined, these produce a Total Tax Incidence of 27.5%, 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.
Recorded imports
Between February 2026 and February 2026, NBR recorded commercial imports under 84121090 in 1 of 6 months, totalling 280 kg at an assessable value of BDT 43,807. That is an average of BDT 156 per kilogram — useful as a rough check on whether a declared value looks plausible. In February 2026 it was the 3,611th largest of 4,051 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |
|---|---|---|---|
| February 2026 | 280 kg | BDT 43,807 | BDT 156 |
Bonded imports. A further 470 kg worth BDT 2,798,296 entered under the bonded-warehouse regime in the same period — goods brought in duty-free as inputs on the undertaking that they leave again as exports, which in Bangladesh overwhelmingly means ready-made garments. That is 98.5% of everything imported under this code. In practice this line is an export input rather than a product entering the domestic market, so the duty rates above apply to only a small fraction of the trade.

How this line compares
Chapter 84 contains 648 tariff lines, averaging 35.59%. At 27.5%, 84121090 sits below that average by 8.09 percentage points. It is the 529th 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 33.58 points.
Within heading 8412 alone, rates run from 12.5% to 28.73% across 9 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.
