HS Code 74032100
Copper-Zinc Base (Brass) Alloys, Unwrought
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 74032100 would be approximately BDT 33,630.00, because the Total Tax Incidence is 33.63% of the assessable value.
What these figures mean
Copper-Zinc Base (Brass) Alloys, Unwrought is classified under HS code 74032100, which sits in heading 7403 (Copper; refined and copper alloys, unwrought) of chapter 74 (Copper and articles thereof).
Under the Bangladesh Operative Tariff 2026-2027 this line attracts Customs Duty of 5%, 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 33.63%, 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 January 2026 and April 2026, NBR recorded commercial imports under 74032100 in 2 of 6 months, totalling 9,942 kg at an assessable value of BDT 11,154,308. That is an average of BDT 1,122 per kilogram — useful as a rough check on whether a declared value looks plausible. In April 2026 it was the 2,174th largest of 4,161 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |
|---|---|---|---|
| January 2026 | 6,342 kg | BDT 6,757,643 | BDT 1,066 |
| April 2026 | 3,600 kg | BDT 4,396,665 | BDT 1,221 |
Bonded imports. A further 12,310 kg worth BDT 20,404,239 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 64.7% of the total value imported under this code, the rest entering commercially.

How this line compares
Chapter 74 contains 53 tariff lines, averaging 42.76%. At 33.63%, 74032100 sits below that average by 9.13 percentage points. It is the 31st 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 27.45 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.
