HS Code 29181990
Carboxylic Acids With Alcohol Function,Without Oxygen Function..Nes
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 29181990 would be approximately BDT 39,750.00, because the Total Tax Incidence is 39.75% of the assessable value.
What these figures mean
Carboxylic Acids With Alcohol Function,Without Oxygen Function..Nes is classified under HS code 29181990, which sits in heading 2918 (Acids; carboxylic acid with additional oxygen function and their anhydrides, halides, peroxides, peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives) of chapter 29 (Organic chemicals).
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 0% and Advance Tax of 7.5%. Combined, these produce a Total Tax Incidence of 39.75%, 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 29181990 in 6 of 6 months, totalling 87,829 kg at an assessable value of BDT 379,284,282. That is an average of BDT 4,318 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 1,460th largest of 4,066 tariff lines by assessable value.

How this line compares
Chapter 29 contains 491 tariff lines, averaging 36.78%. At 39.75%, 29181990 sits above that average by 2.97 percentage points. It is the 26th 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 21.33 points.
Within heading 2918 alone, rates run from 33.63% to 39.75% across 17 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.
