HS Code 51013000
Carbonised Wool, Not Carded Or Combed
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 51013000 would be approximately BDT 10,000.00, because the Total Tax Incidence is 10% of the assessable value.
What these figures mean
Carbonised Wool, Not Carded Or Combed is classified under HS code 51013000, which sits in heading 5101 (Wool, not carded or combed) of chapter 51 (Wool, fine or coarse animal hair; horsehair yarn and woven fabric).
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 0%. Combined, these produce a Total Tax Incidence of 10%, 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 51013000 in 4 of 6 months, totalling 13,074 kg at an assessable value of BDT 24,879,276. That is an average of BDT 1,903 per kilogram — useful as a rough check on whether a declared value looks plausible. In April 2026 it was the 1,286th largest of 4,161 tariff lines by assessable value.

How this line compares
Chapter 51 contains 38 tariff lines, averaging 36.9%. At 10%, 51013000 sits below that average by 26.9 percentage points. It is the 30th 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 51.08 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.
