HS Code 83071000
Flexible Tubing Of Iron Or Steel
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 83071000 would be approximately BDT 39,750.00, because the Total Tax Incidence is 39.75% of the assessable value.
What these figures mean
Flexible Tubing Of Iron Or Steel is classified under HS code 83071000, which sits in heading 8307 (Tubing; flexible, with or without fittings, of base metal) of chapter 83 (Miscellaneous articles of base metal).
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 83071000 in 6 of 6 months, totalling 162,936 kg at an assessable value of BDT 72,066,764. That is an average of BDT 442 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 1,686th largest of 4,066 tariff lines by assessable value.

Bonded imports. A further 1,207 kg worth BDT 3,312,109 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. Bonded entries account for 4.4% of the total value imported under this code, the rest entering commercially.

Chapter 83 contains 45 tariff lines, averaging 68.65%. At 39.75%, 83071000 sits below that average by 28.9 percentage points. It is the 42nd 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.
