HS Code 28042100
0Argon
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 28042100 would be approximately BDT 52,000.00, because the Total Tax Incidence is 52% of the assessable value.
What these figures mean
0Argon is classified under HS code 28042100, which sits in heading 2804 (Hydrogen, rare gases and other non-metals) 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 15% and Advance Tax of 7.5%. Combined, these produce a Total Tax Incidence of 52%, 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 28042100 in 6 of 6 months, totalling 3,193,606 kg at an assessable value of BDT 160,732,504. That is an average of BDT 50 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 913th largest of 4,066 tariff lines by assessable value.

How this line compares
Chapter 28 contains 200 tariff lines, averaging 38.13%. At 52%, 28042100 sits above that average by 13.87 percentage points. It is the 11th 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 9.08 points.
Within heading 2804 alone, rates run from 33.63% to 58.13% across 11 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.
