HS Code 55101210
Water Blocking Yarn
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 55101210 would be approximately BDT 39,750.00, because the Total Tax Incidence is 39.75% of the assessable value.
What these figures mean
Water Blocking Yarn is classified under HS code 55101210, which sits in heading 5510 (Yarn (other than sewing thread) of artificial staple fibres, not put up for retail sale) of chapter 55 (Man-made staple fibres).
Under the Bangladesh Operative Tariff 2026-2027 this line attracts Customs Duty of 10%, 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 39.75%, 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 55101210 in 2 of 6 months, totalling 8 kg at an assessable value of BDT 15,769. That is an average of BDT 1,971 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 3,703rd largest of 4,066 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |
|---|---|---|---|
| December 2025 | 2 kg | BDT 1,487 | BDT 744 |
| May 2026 | 6 kg | BDT 14,282 | BDT 2,380 |
Bonded imports. A further 38,957 kg worth BDT 21,193,755 entered under the bonded-warehouse regime in the same period — goods brought in duty-free as inputs on the undertaking that they leave again as exports, which in Bangladesh overwhelmingly means ready-made garments. That is over 99.9% of everything imported under this code. In practice this line is an export input rather than a product entering the domestic market, so the duty rates above apply to only a small fraction of the trade.

How this line compares
Chapter 55 contains 113 tariff lines, averaging 62%. At 39.75%, 55101210 sits below that average by 22.25 percentage points. It is the 62nd 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 21.33 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.
