HS Code 84211910
Other Centrifuges,Including Contrifugal Dryers Nes, For Laboratory Use
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 84211910 would be approximately BDT 28,730.00, because the Total Tax Incidence is 28.73% of the assessable value.
What these figures mean
Other Centrifuges,Including Contrifugal Dryers Nes, For Laboratory Use is classified under HS code 84211910, which sits in heading 8421 (Centrifuges, including centrifugal dryers; filtering or purifying machinery and apparatus for liquids or gases) 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 15%, Advance Income Tax of 5%, Regulatory Duty of 0% and Advance Tax of 7.5%. Combined, these produce a Total Tax Incidence of 28.73%, 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 May 2026, NBR recorded commercial imports under 84211910 in 6 of 6 months, totalling 145,241 kg at an assessable value of BDT 207,823,752. That is an average of BDT 1,431 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 539th largest of 4,066 tariff lines by assessable value.

Bonded imports. A further 1,055 kg worth BDT 6,249,791 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 2.9% of the total value imported under this code, the rest entering commercially.

How this line compares
Chapter 84 contains 648 tariff lines, averaging 35.59%. At 28.73%, 84211910 sits below that average by 6.86 percentage points. It is the 166th 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 32.35 points.
Within heading 8421 alone, rates run from 7.5% to 96.1% across 29 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.
