HS Code 90183918
Fistula Needle
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 90183918 would be approximately BDT 31,500.00, because the Total Tax Incidence is 31.5% of the assessable value.
What these figures mean
Fistula Needle is classified under HS code 90183918, 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 10%, Supplementary Duty of 0%, VAT of 15%, Advance Income Tax of 5%, Regulatory Duty of 0% and Advance Tax of 0%. Combined, these produce a Total Tax Incidence of 31.5%, 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 90183918 in 5 of 6 months, totalling 66,603 kg at an assessable value of BDT 24,146,321. That is an average of BDT 363 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 1,716th largest of 4,066 tariff lines by assessable value.

How this line compares
Chapter 90 contains 184 tariff lines, averaging 32.72%. At 31.5%, 90183918 sits below that average by 1.22 percentage points. It is the 81st 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 29.58 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.
