HS Code 29224100
Lysine And Its Esters; Salts Thereof
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 29224100 would be approximately BDT 17,880.00, because the Total Tax Incidence is 17.88% of the assessable value.
What these figures mean
Lysine And Its Esters; Salts Thereof is classified under HS code 29224100, which sits in heading 2922 (Oxygen-function amino-compounds) of chapter 29 (Organic chemicals).
Under the Bangladesh Operative Tariff 2026-2027 this line attracts Customs Duty of 5%, Supplementary Duty of 0%, VAT of 0%, Advance Income Tax of 5%, Regulatory Duty of 0% and Advance Tax of 7.5%. Combined, these produce a Total Tax Incidence of 17.88%, 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 29224100 in 6 of 6 months, totalling 7,072,263 kg at an assessable value of BDT 1,473,741,314. That is an average of BDT 208 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 308th largest of 4,066 tariff lines by assessable value.

How this line compares
Chapter 29 contains 491 tariff lines, averaging 36.78%. At 17.88%, 29224100 sits below that average by 18.9 percentage points. It is the 481st 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 43.2 points.
Within heading 2922 alone, rates run from 17.88% to 64.25% across 23 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.
