What these figures mean
Ozone Therapy,Oxygen Therapy,Aerosol Therapy,Respiration Apparatus Nes. is classified under HS code 90192090, which sits in heading 9019 (Mechano-therapy, massage appliances; psychological aptitude testing apparatus; ozone, oxygen, aerosol therapy, artificial respiration or other therapeutic respiration apparatus) 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 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.

How this line compares
Chapter 90 contains 184 tariff lines, averaging 32.72%. At 28.73%, 90192090 sits below that average by 3.99 percentage points. It is the 82nd 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 9019 alone, rates run from 12.5% to 33.63% across 5 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.
