HS Code 28332920
CHROMIUM SULPHATE
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 28332920 would be approximately BDT 33,630.00, because the Total Tax Incidence is 33.63% of the assessable value.
What these figures mean
CHROMIUM SULPHATE is classified under HS code 28332920, which sits in heading 2833 (Sulphates; alums; peroxosulphates (persulphates)) 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 April 2026 and May 2026, NBR recorded commercial imports under 28332920 in 2 of 6 months, totalling 201,770 kg at an assessable value of BDT 23,811,211. That is an average of BDT 118 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 1,433rd largest of 4,066 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |
|---|---|---|---|
| April 2026 | 101,750 kg | BDT 11,737,328 | BDT 115 |
| May 2026 | 100,020 kg | BDT 12,073,883 | BDT 121 |
Bonded imports. A further 3,068,000 kg worth BDT 366,086,117 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. That is 93.9% of everything imported under this code. In practice this line is an export input rather than a product entering the domestic market, so the duty rates above apply to only a small fraction of the trade.

How this line compares
Chapter 28 contains 200 tariff lines, averaging 38.13%. At 33.63%, 28332920 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 2833 alone, rates run from 9.5% to 96.1% across 12 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.
