HS Code 28342910
Sodium nitrate
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 28342910 would be approximately BDT 33,630.00, because the Total Tax Incidence is 33.63% of the assessable value.
What these figures mean
Sodium nitrate is classified under HS code 28342910, which sits in heading 2834 (Nitrites; nitrates) 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 April 2026, NBR recorded commercial imports under 28342910 in 5 of 6 months, totalling 871,003 kg at an assessable value of BDT 119,768,177. That is an average of BDT 138 per kilogram — useful as a rough check on whether a declared value looks plausible. In April 2026 it was the 2,406th largest of 4,161 tariff lines by assessable value.

How this line compares
Chapter 28 contains 200 tariff lines, averaging 38.13%. At 33.63%, 28342910 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.
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.
