HS Code 55081000
Sewing Thread Of Synthetic Staple Fibres
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 55081000 would be approximately BDT 39,750.00, because the Total Tax Incidence is 39.75% of the assessable value.
What these figures mean
Sewing Thread Of Synthetic Staple Fibres is classified under HS code 55081000, which sits in heading 5508 (Sewing thread of man-made staple fibres, whether or 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 55081000 in 6 of 6 months, totalling 4,202 kg at an assessable value of BDT 1,382,843. That is an average of BDT 329 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 3,567th largest of 4,066 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |
|---|---|---|---|
| December 2025 | 1,040 kg | BDT 351,041 | BDT 338 |
| January 2026 | 1,504 kg | BDT 490,887 | BDT 326 |
| February 2026 | 1,146 kg | BDT 362,949 | BDT 317 |
| March 2026 | 125 kg | BDT 72,270 | BDT 578 |
| April 2026 | 269 kg | BDT 74,264 | BDT 276 |

Bonded imports. A further 931,332 kg worth BDT 1,165,006,846 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 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.

Chapter 55 contains 113 tariff lines, averaging 62%. At 39.75%, 55081000 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.
