HS Code 31042000
Potassium Chloride
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 31042000 would be approximately BDT 7,500.00, because the Total Tax Incidence is 7.5% of the assessable value.
What these figures mean
Potassium Chloride is classified under HS code 31042000, which sits in heading 3104 (Fertilizers; mineral or chemical, potassic) of chapter 31 (Fertilisers).
Under the Bangladesh Operative Tariff 2026-2027 this line attracts Customs Duty of 0%, Supplementary Duty of 0%, VAT of 0%, Advance Income Tax of 0%, Regulatory Duty of 0% and Advance Tax of 7.5%. Combined, these produce a Total Tax Incidence of 7.5%, 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 31042000 in 6 of 6 months, totalling 694,432,179 kg at an assessable value of BDT 32,915,895,263. That is an average of BDT 47 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 12th largest of 4,066 tariff lines by assessable value.

How this line compares
Chapter 31 contains 26 tariff lines, averaging 14.63%. At 7.5%, 31042000 sits below that average by 7.13 percentage points. It is the 10th 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 53.58 points.
Within heading 3104 alone, rates run from 7.5% to 12.5% across 3 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.
