HS Code 54021100
Synthetic filament yarn?High tenacity of nylon or other polyamides Of aramids
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 54021100 would be approximately BDT 39,750.00, because the Total Tax Incidence is 39.75% of the assessable value.
What these figures mean
Synthetic filament yarn?High tenacity of nylon or other polyamides Of aramids is classified under HS code 54021100, which sits in heading 5402 (Synthetic filament yarn (other than sewing thread), not put up for retail sale, including synthetic monofilament of less than 67 decitex) of chapter 54 (Man-made filaments; strip and the like of man-made textile materials).
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 December 2025, NBR recorded commercial imports under 54021100 in 1 of 6 months, totalling 3 kg at an assessable value of BDT 2,257. That is an average of BDT 752 per kilogram — useful as a rough check on whether a declared value looks plausible. In December 2025 it was the 4,101st largest of 4,219 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |
|---|---|---|---|
| December 2025 | 3 kg | BDT 2,257 | BDT 752 |
Bonded imports. A further 291,196 kg worth BDT 98,942,013 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 54 contains 73 tariff lines, averaging 53.5%. At 39.75%, 54021100 sits below that average by 13.75 percentage points. It is the 38th 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.
Within heading 5402 alone, rates run from 27.5% to 64.25% across 22 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.
