HS Code 84012000
Machinery And Apparatus For Isotopic Separation, Parts Thereof
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 84012000 would be approximately BDT 27,500.00, because the Total Tax Incidence is 27.5% of the assessable value.
What these figures mean
Machinery And Apparatus For Isotopic Separation, Parts Thereof is classified under HS code 84012000, which sits in heading 8401 (Nuclear reactors; fuel elements (cartridges), non-irradiated, for nuclear reactors, machinery and apparatus for isotopic separation) 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
NBR recorded no commercial imports under 84012000 between December 2025 and May 2026. That is not unusual — roughly a third of the 7,469 lines in the schedule saw no commercial import in that window. Goods may still have entered under a bonded-warehouse regime, or been declared under a neighbouring code.

How this line compares
Chapter 84 contains 648 tariff lines, averaging 35.59%. At 27.5%, 84012000 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.
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.
