HS Code 84021900
Other Vapour Generating Boilers, Nes (Incl. Hybrid Boilers)
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 84021900 would be approximately BDT 28,730.00, because the Total Tax Incidence is 28.73% of the assessable value.
What these figures mean
Other Vapour Generating Boilers, Nes (Incl. Hybrid Boilers) is classified under HS code 84021900, which sits in heading 8402 (Boilers; steam or other vapour generating (other than central heating hot water boilers, capable also of producing low pressure steam), super heated water boilers) 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 84021900 in 6 of 6 months, totalling 2,084,789 kg at an assessable value of BDT 1,547,985,429. That is an average of BDT 743 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 330th largest of 4,066 tariff lines by assessable value.

Bonded imports. A further 108,997 kg worth BDT 65,130,843 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 4.0% 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%, 84021900 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.
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.
