HS Code 29171200
Adipic Acid, Its Salts And Esters
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 29171200 would be approximately BDT 39,750.00, because the Total Tax Incidence is 39.75% of the assessable value.
What these figures mean
Adipic Acid, Its Salts And Esters is classified under HS code 29171200, 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 29171200 in 6 of 6 months, totalling 657,516 kg at an assessable value of BDT 120,725,438. That is an average of BDT 184 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 2,101st largest of 4,066 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |
|---|---|---|---|
| December 2025 | 160,635 kg | BDT 38,702,075 | BDT 241 |
| January 2026 | 72,821 kg | BDT 23,097,224 | BDT 317 |
| February 2026 | 153,900 kg | BDT 17,884,705 | BDT 116 |
| March 2026 | 69,410 kg | BDT 8,330,917 | BDT 120 |
| April 2026 | 177,035 kg | BDT 29,089,548 | BDT 164 |
| May 2026 | 23,715 kg | BDT 3,620,969 | BDT 153 |
Bonded imports. A further 2,280 kg worth BDT 661,373 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 0.5% 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%, 29171200 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.
