HS Code 29025000
Styrene
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 29025000 would be approximately BDT 23,250.00, because the Total Tax Incidence is 23.25% of the assessable value.
What these figures mean
Styrene is classified under HS code 29025000, which sits in heading 2902 (Cyclic hydrocarbons) 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 0%, Advance Income Tax of 5%, Regulatory Duty of 0% and Advance Tax of 7.5%. Combined, these produce a Total Tax Incidence of 23.25%, 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 29025000 in 6 of 6 months, totalling 1,822,250 kg at an assessable value of BDT 360,581,636. That is an average of BDT 198 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 578th largest of 4,066 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |
|---|---|---|---|
| December 2025 | 408,855 kg | BDT 76,938,737 | BDT 188 |
| January 2026 | 308,575 kg | BDT 69,835,365 | BDT 226 |
| February 2026 | 199,300 kg | BDT 45,333,244 | BDT 227 |
| March 2026 | 347,370 kg | BDT 74,685,105 | BDT 215 |
| April 2026 | 189,530 kg | BDT 26,063,037 | BDT 138 |
| May 2026 | 368,620 kg | BDT 67,726,148 | BDT 184 |
Bonded imports. A further 320,376 kg worth BDT 63,797,006 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 15.0% 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 23.25%, 29025000 sits below that average by 13.53 percentage points. It is the 480th 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 37.83 points.
Within heading 2902 alone, rates run from 23.25% to 45.88% 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.
