HS Code 25210090
Other than Boulder Limestone
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 25210090 would be approximately BDT 72,210.00, because the Total Tax Incidence is 72.21% of the assessable value.
What these figures mean
Other than Boulder Limestone is classified under HS code 25210090, which sits in heading 2521 (Limestone flux; limestone and other calcareous stone, of a kind used for the manufacture of lime or cement) of chapter 25 (Salt; sulphur; earths and stone; plastering materials, lime and cement).
Under the Bangladesh Operative Tariff 2026-2027 this line attracts Customs Duty of 5%, Supplementary Duty of 30%, 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 72.21%, 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 25210090 in 6 of 6 months, totalling 608,222,039 kg at an assessable value of BDT 967,772,177. That is an average of BDT 2 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 3,282nd largest of 4,066 tariff lines by assessable value.

How this line compares
Chapter 25 contains 79 tariff lines, averaging 52.49%. At 72.21%, 25210090 sits above that average by 19.72 percentage points. It is the 14th most heavily taxed line in the chapter.
Across the whole Operative Tariff the mean is 61.08%, so this line is dearer than the typical import by 11.13 points.
Within heading 2521 alone, rates run from 46.49% to 72.21% across 2 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.
This line carries supplementary duty of 30%. Only 1,633 of 7,469 lines carry any SD at all, and because it is charged after customs and regulatory duty, and VAT is then charged on top of it, it affects the total far more than the rate alone suggests.
