HS Code 11081300
Potato Starch
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 11081300 would be approximately BDT 58,130.00, because the Total Tax Incidence is 58.13% of the assessable value.
What these figures mean
Potato Starch is classified under HS code 11081300, which sits in heading 1108 (Starches; inulin) of chapter 11 (Products of the milling industry; malt; starches; inulin; wheat gluten).
Under the Bangladesh Operative Tariff 2026-2027 this line attracts Customs Duty of 15%, Supplementary Duty of 0%, VAT of 15%, Advance Income Tax of 5%, Regulatory Duty of 10% and Advance Tax of 7.5%. Combined, these produce a Total Tax Incidence of 58.13%, 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 11081300 in 6 of 6 months, totalling 557,546 kg at an assessable value of BDT 79,075,206. That is an average of BDT 142 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 1,783rd largest of 4,066 tariff lines by assessable value.

How this line compares
Chapter 11 contains 34 tariff lines, averaging 51.75%. At 58.13%, 11081300 sits above that average by 6.38 percentage points. It is the 16th 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 2.95 points.
Within heading 1108 alone, rates run from 45.88% to 82.63% across 6 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.
