HS Code 84842000
Mechanical Seals
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 84842000 would be approximately BDT 28,730.00, because the Total Tax Incidence is 28.73% of the assessable value.
What these figures mean
Mechanical Seals is classified under HS code 84842000, which sits in heading 8484 (Gaskets and similar joints of metal sheeting combined with other material or of two or more layers of metal; sets or assortments of gaskets and similar joints, dissimilar in composition, put up in pouches, envelopes or similar packings; mechanical seals) of chapter 84 (Nuclear reactors, boilers, machinery and mechanical appliances; parts thereof).
Under the Bangladesh Operative Tariff 2026-2027 this line attracts Customs Duty of 1%, 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 28.73%, 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 84842000 in 6 of 6 months, totalling 60,000 kg at an assessable value of BDT 370,031,931. That is an average of BDT 6,167 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 646th largest of 4,066 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |

| February 2026 | 23,616 kg | BDT 16,852,884 | BDT 714 |
| March 2026 | 8,366 kg | BDT 25,479,776 | BDT 3,046 |

Bonded imports. A further 49 kg worth BDT 4,928,420 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 1.3% of the total value imported under this code, the rest entering commercially.

How this line compares
Chapter 84 contains 648 tariff lines, averaging 35.59%. At 28.73%, 84842000 sits below that average by 6.86 percentage points. It is the 166th 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 32.35 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.
