HS Code 73081000
Bridges And Bridge-Sections Of Iron Or Steel
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 73081000 would be approximately BDT 64,250.00, because the Total Tax Incidence is 64.25% of the assessable value.
What these figures mean
Bridges And Bridge-Sections Of Iron Or Steel is classified under HS code 73081000, which sits in heading 7308 (Structures of iron or steel and parts thereof; plates, rods, angles, shapes, sections, tubes and the like, prepared for use in structures) of chapter 73 (Articles of iron or steel).
Under the Bangladesh Operative Tariff 2026-2027 this line attracts Customs Duty of 25%, Supplementary Duty of 0%, VAT of 15%, Advance Income Tax of 5%, Regulatory Duty of 5% and Advance Tax of 7.5%. Combined, these produce a Total Tax Incidence of 64.25%, 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 73081000 in 6 of 6 months, totalling 633,900 kg at an assessable value of BDT 172,167,840. That is an average of BDT 272 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 2,194th largest of 4,066 tariff lines by assessable value.

Bonded imports. A further 14,160 kg worth BDT 3,272,216 entered under the bonded-warehouse regime in the same period — goods brought in duty-free as inputs on the undertaking that they leave again as exports, which in Bangladesh overwhelmingly means ready-made garments. Bonded entries account for 1.9% of the total value imported under this code, the rest entering commercially.

How this line compares
Chapter 73 contains 157 tariff lines, averaging 64.73%. At 64.25%, 73081000 sits below that average by 0.48 percentage points. It is the 37th 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 3.17 points.
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.
