HS Code 73182400
Cotters And Cotter-Pins Of Iron/Steel
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 73182400 would be approximately BDT 64,250.00, because the Total Tax Incidence is 64.25% of the assessable value.
What these figures mean
Cotters And Cotter-Pins Of Iron/Steel is classified under HS code 73182400, which sits in heading 7318 (Screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, cotter-pins, washers (including spring washers) and similar articles, of iron or steel) 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.

Bonded imports. A further 1,589 kg worth BDT 2,162,619 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 7.2% 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%, 73182400 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.
Within heading 7318 alone, rates run from 39.75% to 96.1% across 15 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.
