HS Code 73090010
Silo
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 73090010 would be approximately BDT 33,630.00, because the Total Tax Incidence is 33.63% of the assessable value.
What these figures mean
Silo is classified under HS code 73090010, which sits in heading 7309 (Reservoirs, tanks, vats and similar containers; for any material (excluding compressed or liquefied gas), of iron or steel, capacity exceeding 300l, whether or not lined or heat insulated) of chapter 73 (Articles of iron or steel).
Under the Bangladesh Operative Tariff 2026-2027 this line attracts Customs Duty of 5%, 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 33.63%, 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 73090010 in 6 of 6 months, totalling 605,803 kg at an assessable value of BDT 196,909,512. That is an average of BDT 325 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 1,148th largest of 4,066 tariff lines by assessable value.

How this line compares
Chapter 73 contains 157 tariff lines, averaging 64.73%. At 33.63%, 73090010 sits below that average by 31.1 percentage points. It is the 146th 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 27.45 points.
Within heading 7309 alone, rates run from 33.63% to 39.75% across 2 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.
