HS Code 90251100
Thermometers/Pyrometrs,Not Comb.With Other Instrs,Liquid,For Direct Readng
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 90251100 would be approximately BDT 33,630.00, because the Total Tax Incidence is 33.63% of the assessable value.
What these figures mean
Thermometers/Pyrometrs,Not Comb.With Other Instrs,Liquid,For Direct Readng is classified under HS code 90251100, which sits in heading 9025 (Hydrometers and similar floating instruments, thermometers, pyrometers, barometers, hygrometers and psychrometers, recording or not) of chapter 90 (Optical, photographic, measuring, checking, precision, medical or surgical instruments).
Under the Bangladesh Operative Tariff 2026-2027 this line attracts Customs Duty of 5%, 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 33.63%, 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.

That is an average of BDT 468 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 2,992nd largest of 4,066 tariff lines by assessable value.

How this line compares
Chapter 90 contains 184 tariff lines, averaging 32.72%. At 33.63%, 90251100 sits above that average by 0.91 percentage points. It is the 58th 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 27.45 points.
Within heading 9025 alone, rates run from 28.73% to 33.63% across 4 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.
