HS Code 84021100
Watertube Boilers With A Steam Production >45t/Hour
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 84021100 would be approximately BDT 28,730.00, because the Total Tax Incidence is 28.73% of the assessable value.
What these figures mean
Watertube Boilers With A Steam Production >45t/Hour is classified under HS code 84021100, 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.
