HS Code 39093100
Poly(methylene phenyl isocyanate) (crude MDI, polymeric MDI)
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 39093100 would be approximately BDT 39,750.00, because the Total Tax Incidence is 39.75% of the assessable value.
What these figures mean
Poly(methylene phenyl isocyanate) (crude MDI, polymeric MDI) is classified under HS code 39093100, which sits in heading 3909 (Amino-resins, phenolic resins and polyurethanes, in primary forms) of chapter 39 (Plastics and articles thereof).
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 39093100 in 6 of 6 months, totalling 9,441,897 kg at an assessable value of BDT 2,690,305,239. That is an average of BDT 285 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 149th largest of 4,066 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |
|---|---|---|---|
| December 2025 | 1,661,313 kg | BDT 564,429,861 | BDT 340 |
| January 2026 | 2,008,274 kg | BDT 630,657,350 | BDT 314 |
| February 2026 | 1,163,430 kg | BDT 356,502,164 | BDT 306 |
| March 2026 | 1,058,170 kg | BDT 318,140,520 | BDT 301 |
| April 2026 | 1,867,995 kg | BDT 407,484,097 | BDT 218 |

Bonded imports. A further 128,590 kg worth BDT 39,934,179 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 1.5% of the total value imported under this code, the rest entering commercially.

How this line compares
Chapter 39 contains 185 tariff lines, averaging 57.55%. At 39.75%, 39093100 sits below that average by 17.8 percentage points. It is the 92nd 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 3909 alone, rates run from 33.63% to 52% across 6 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.
