HS Code 38111100
Anti-Knock Preparations Based On Lead Compounds
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 38111100 would be approximately BDT 33,630.00, because the Total Tax Incidence is 33.63% of the assessable value.
What these figures mean
Anti-Knock Preparations Based On Lead Compounds is classified under HS code 38111100, which sits in heading 3811 (Anti-knock preparations, oxidation and gum inhibitors, viscosity improvers, anti-corrosive preparations and the like, for mineral oils (including gasoline) or other liquids used for the same purposes) of chapter 38 (Miscellaneous chemical products).
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 March 2026 and March 2026, NBR recorded commercial imports under 38111100 in 1 of 6 months, totalling 1 kg at an assessable value of BDT 627. That is an average of BDT 627 per kilogram — useful as a rough check on whether a declared value looks plausible. In March 2026 it was the 4,030th largest of 4,054 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |

How this line compares
Chapter 38 contains 139 tariff lines, averaging 43.88%. At 33.63%, 38111100 sits below that average by 10.25 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 27.45 points.
Within heading 3811 alone, rates run from 33.63% to 39.75% across 5 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.
