HS Code 29171900
Acyclic polycarboxylic acids, etc, their... derivatives, nes
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 29171900 would be approximately BDT 39,750.00, because the Total Tax Incidence is 39.75% of the assessable value.
What these figures mean
Acyclic polycarboxylic acids, etc, their... derivatives, nes is classified under HS code 29171900, which sits in heading 2917 (Acids; polycarboxylic acids, their anhydrides, halides, peroxides and peroxy-acids; 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 29171900 in 6 of 6 months, totalling 181,677 kg at an assessable value of BDT 149,059,267. That is an average of BDT 820 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 1,810th largest of 4,066 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |
|---|---|---|---|
| December 2025 | 21,644 kg | BDT 32,751,580 | BDT 1,513 |
| January 2026 | 58,130 kg | BDT 58,333,892 | BDT 1,004 |
| February 2026 | 33,570 kg | BDT 17,557,151 | BDT 523 |
| March 2026 | 17,647 kg | BDT 12,888,342 | BDT 730 |
| April 2026 | 39,856 kg | BDT 21,191,185 | BDT 532 |

Bonded imports. A further 38,400 kg worth BDT 9,753,012 entered under the bonded-warehouse regime in the same period — goods brought in duty-free as inputs on the undertaking that they leave again as exports, which in Bangladesh overwhelmingly means ready-made garments. Bonded entries account for 6.1% of the total value imported under this code, the rest entering commercially.

How this line compares
Chapter 29 contains 491 tariff lines, averaging 36.78%. At 39.75%, 29171900 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 2917 alone, rates run from 33.63% to 80.18% across 14 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.
