HS Code 73182100
Non-Threaded Spring Washers And Other Lock Washers Of Iron/Steel
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 73182100 would be approximately BDT 45,880.00, because the Total Tax Incidence is 45.88% of the assessable value.
What these figures mean
Non-Threaded Spring Washers And Other Lock Washers Of Iron/Steel is classified under HS code 73182100, 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 10%, 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 45.88%, 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 73 contains 157 tariff lines, averaging 64.73%. At 45.88%, 73182100 sits below that average by 18.85 percentage points. It is the 115th 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 15.2 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.
