HS Code 90121000
Microscopes (Excl. Optical Microscopes) And Diffraction Apparatus
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 90121000 would be approximately BDT 28,730.00, because the Total Tax Incidence is 28.73% of the assessable value.
What these figures mean
Microscopes (Excl. Optical Microscopes) And Diffraction Apparatus is classified under HS code 90121000, which sits in heading 9012 (Microscopes (excluding optical microscopes); diffraction apparatus) of chapter 90 (Optical, photographic, measuring, checking, precision, medical or surgical instruments).
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 90121000 in 5 of 6 months, totalling 6,884 kg at an assessable value of BDT 261,849,168. That is an average of BDT 38,037 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 522nd largest of 4,066 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |
|---|---|---|---|

Bonded imports. A further 0 kg worth BDT 22,855 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 0.0% of the total value imported under this code, the rest entering commercially.

How this line compares
Chapter 90 contains 184 tariff lines, averaging 32.72%. At 28.73%, 90121000 sits below that average by 3.99 percentage points. It is the 82nd 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.
