HS Code 84303900
Coal Or Rock Cutters And Tunnelling Machinery (Not Self-Propelled)
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 84303900 would be approximately BDT 28,730.00, because the Total Tax Incidence is 28.73% of the assessable value.
What these figures mean
Coal Or Rock Cutters And Tunnelling Machinery (Not Self-Propelled) is classified under HS code 84303900, which sits in heading 8430 (Moving, grading, levelling, scraping, excavating, tamping, compacting, extracting or boring machinery, for earth, minerals, or ores; pile drivers and extractors; snow ploughs and snow blowers) 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 December 2025, NBR recorded commercial imports under 84303900 in 1 of 6 months, totalling 18,000 kg at an assessable value of BDT 4,918,969. That is an average of BDT 273 per kilogram — useful as a rough check on whether a declared value looks plausible. In December 2025 it was the 2,237th largest of 4,219 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |

How this line compares
Chapter 84 contains 648 tariff lines, averaging 35.59%. At 28.73%, 84303900 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 8430 alone, rates run from 12.5% to 28.73% across 12 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.
