HS Code 83091000
Crown Corks Of Base Metal
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 83091000 would be approximately BDT 64,250.00, because the Total Tax Incidence is 64.25% of the assessable value.
What these figures mean
Crown Corks Of Base Metal is classified under HS code 83091000, which sits in heading 8309 (Stoppers, caps, lids (including crown corks, screw caps, pouring stoppers); capsules for bottles, threaded bungs, bung covers, seals and other packaging accessories, of base metal) of chapter 83 (Miscellaneous articles of base metal).
Under the Bangladesh Operative Tariff 2026-2027 this line attracts Customs Duty of 25%, Supplementary Duty of 0%, VAT of 15%, Advance Income Tax of 5%, Regulatory Duty of 5% and Advance Tax of 7.5%. Combined, these produce a Total Tax Incidence of 64.25%, 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 April 2026, NBR recorded commercial imports under 83091000 in 5 of 6 months, totalling 2,531 kg at an assessable value of BDT 613,145. That is an average of BDT 242 per kilogram — useful as a rough check on whether a declared value looks plausible. In April 2026 it was the 4,061st largest of 4,161 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |
|---|---|---|---|
| December 2025 | 28 kg | BDT 45,465 | BDT 1,624 |

Bonded imports. A further 95 kg worth BDT 272,062 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 30.7% of the total value imported under this code, the rest entering commercially.

How this line compares
Chapter 83 contains 45 tariff lines, averaging 68.65%. At 64.25%, 83091000 sits below that average by 4.4 percentage points. It is the 11th most heavily taxed line in the chapter.
Across the whole Operative Tariff the mean is 61.08%, so this line is dearer than the typical import by 3.17 points.
Within heading 8309 alone, rates run from 33.63% to 135.91% across 6 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.
