HS Code 23099013
Probiotics or Prebiotics or their combinatioin (feed grade)
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 23099013 would be approximately BDT 14,880.00, because the Total Tax Incidence is 14.88% of the assessable value.
What these figures mean
Probiotics or Prebiotics or their combinatioin (feed grade) is classified under HS code 23099013, which sits in heading 2309 (Preparations of a kind used in animal feeding) of chapter 23 (Residues and waste from the food industries; prepared animal fodder).
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 2%, Regulatory Duty of 0% and Advance Tax of 7.5%. Combined, these produce a Total Tax Incidence of 14.88%, 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 23099013 in 6 of 6 months, totalling 3,406,399 kg at an assessable value of BDT 1,632,106,210. That is an average of BDT 479 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 286th largest of 4,066 tariff lines by assessable value.

How this line compares
Chapter 23 contains 36 tariff lines, averaging 19.96%. At 14.88%, 23099013 sits below that average by 5.08 percentage points. It is the 14th 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 46.2 points.
Within heading 2309 alone, rates run from 14.88% to 80.18% 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.
