HS Code 28366000
Barium Carbonate
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 28366000 would be approximately BDT 33,630.00, because the Total Tax Incidence is 33.63% of the assessable value.
What these figures mean
Barium Carbonate is classified under HS code 28366000, which sits in heading 2836 (Carbonates; peroxocarbonates (percarbonates); commercial ammonium carbonate containing ammonium carbamate) of chapter 28 (Inorganic chemicals; compounds of precious metals, rare-earth metals, radioactive elements or isotopes).
Under the Bangladesh Operative Tariff 2026-2027 this line attracts Customs Duty of 5%, 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 33.63%, 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 28366000 in 6 of 6 months, totalling 1,238,600 kg at an assessable value of BDT 117,670,841. That is an average of BDT 95 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 1,595th largest of 4,066 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |
|---|---|---|---|

| January 2026 | 237,000 kg | BDT 21,773,867 | BDT 92 |
| February 2026 | 113,000 kg | BDT 9,554,558 | BDT 85 |
| March 2026 | 616,500 kg | BDT 58,628,666 | BDT 95 |
| April 2026 | 54,100 kg | BDT 3,653,454 | BDT 68 |
| May 2026 | 133,000 kg | BDT 9,457,359 | BDT 71 |
Bonded imports. A further 25 kg worth BDT 13,158 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 0.0% of the total value imported under this code, the rest entering commercially.

How this line compares
Chapter 28 contains 200 tariff lines, averaging 38.13%. At 33.63%, 28366000 sits below that average by 4.5 percentage points. It is the 126th 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 27.45 points.
Within heading 2836 alone, rates run from 33.63% to 39.75% across 9 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.
