HS Code 84109000
Parts Of Hydraulic Turbines, Water Wheels Including Regulators
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 84109000 would be approximately BDT 27,500.00, because the Total Tax Incidence is 27.5% of the assessable value.
What these figures mean
Parts Of Hydraulic Turbines, Water Wheels Including Regulators is classified under HS code 84109000, which sits in heading 8410 (Turbines; hydraulic water wheels and regulators therefor) 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 December 2025 and January 2026, NBR recorded commercial imports under 84109000 in 2 of 6 months, totalling 19,372 kg at an assessable value of BDT 30,375,052. That is an average of BDT 1,568 per kilogram — useful as a rough check on whether a declared value looks plausible. In January 2026 it was the 3,953rd largest of 4,179 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |
|---|---|---|---|
| December 2025 | 19,352 kg | BDT 30,367,539 | BDT 1,569 |
| January 2026 | 20 kg | BDT 7,513 | BDT 376 |
Bonded imports. A further 24 kg worth BDT 93,063 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. Bonded entries account for 0.3% of the total value imported under this code, the rest entering commercially.
