HS Code 90181990
Other Electro-Diagnostic Apparatus Nes
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 90181990 would be approximately BDT 28,730.00, because the Total Tax Incidence is 28.73% of the assessable value.
What these figures mean
Other Electro-Diagnostic Apparatus Nes is classified under HS code 90181990, which sits in heading 9018 (Instruments and appliances used in medical, surgical, dental or veterinary sciences, including scintigraphic apparatus, other electro-medical apparatus and sight testing instruments) 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.
Recorded imports
Between December 2025 and May 2026, NBR recorded commercial imports under 90181990 in 6 of 6 months, totalling 13,362 kg at an assessable value of BDT 541,847,805. That is an average of BDT 40,551 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 648th largest of 4,066 tariff lines by assessable value.

How this line compares
Chapter 90 contains 184 tariff lines, averaging 32.72%. At 28.73%, 90181990 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 9018 alone, rates run from 1% to 64.25% across 34 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.
