HS Code 25070090
Kaolin And Other Kaolinic Clays, Whether Or Not Calcined
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 25070090 would be approximately BDT 45,880.00, because the Total Tax Incidence is 45.88% of the assessable value.
What these figures mean
Kaolin And Other Kaolinic Clays, Whether Or Not Calcined is classified under HS code 25070090, which sits in heading 2507 (Kaolin and other kaolinic clays; whether or not calcined) of chapter 25 (Salt; sulphur; earths and stone; plastering materials, lime and cement).
Under the Bangladesh Operative Tariff 2026-2027 this line attracts Customs Duty of 15%, 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 45.88%, 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 25070090 in 6 of 6 months, totalling 8,639,942 kg at an assessable value of BDT 247,672,166. That is an average of BDT 29 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 936th largest of 4,066 tariff lines by assessable value.

Bonded imports. A further 1,434 kg worth BDT 647,465 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 0.3% of the total value imported under this code, the rest entering commercially.

How this line compares
Chapter 25 contains 79 tariff lines, averaging 52.49%. At 45.88%, 25070090 sits below that average by 6.61 percentage points. It is the 30th 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 15.2 points.
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.
