HS Code 84041000
Auxiliary Plant For Use With Boilers Of 84.02 Or 84.03
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 84041000 would be approximately BDT 28,730.00, because the Total Tax Incidence is 28.73% of the assessable value.
What these figures mean
Auxiliary Plant For Use With Boilers Of 84.02 Or 84.03 is classified under HS code 84041000, which sits in heading 8404 (Auxiliary plant for use with boilers of heading no. 8402 or 8403; e.g. economisers, super-heaters, soot removers, gas recoverers), condensers for steam or other vapour power units) 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 84041000 in 5 of 6 months, totalling 18,274 kg at an assessable value of BDT 22,125,015. That is an average of BDT 1,211 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 1,439th largest of 4,066 tariff lines by assessable value.
