HS Code 28258000
Antimony Oxides
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 28258000 would be approximately BDT 39,750.00, because the Total Tax Incidence is 39.75% of the assessable value.
What these figures mean
Antimony Oxides is classified under HS code 28258000, which sits in heading 2825 (Hydrazine and hydroxylamine and their inorganic salts; other inorganic bases; other metal oxides, hydroxides and peroxides) 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 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 February 2026 and April 2026, NBR recorded commercial imports under 28258000 in 2 of 6 months, totalling 11,000 kg at an assessable value of BDT 29,763,910. That is an average of BDT 2,706 per kilogram — useful as a rough check on whether a declared value looks plausible. In April 2026 it was the 1,292nd largest of 4,161 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |

How this line compares
Chapter 28 contains 200 tariff lines, averaging 38.13%. At 39.75%, 28258000 sits above that average by 1.62 percentage points. It is the 12th 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 2825 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.
