HS Code 34039920
Semi-synthetic lubricating oil
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 34039920 would be approximately BDT 52,000.00, because the Total Tax Incidence is 52% of the assessable value.
What these figures mean
Semi-synthetic lubricating oil is classified under HS code 34039920, which sits in heading 3403 (Lubricating preparations and those used in oil or grease treatment of textile and similar materials; excluding preparations containing 70% or more (by weight) of petroleum or bituminous mineral oils) of chapter 34 (Soap, organic surface-active agents, washing and lubricating preparations, waxes, candles, modelling pastes).
Under the Bangladesh Operative Tariff 2026-2027 this line attracts Customs Duty of 15%, 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 52%, 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 34039920 in 6 of 6 months, totalling 771,697 kg at an assessable value of BDT 306,750,272. That is an average of BDT 398 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 639th largest of 4,066 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |
|---|---|---|---|
| December 2025 | 81,634 kg | BDT 34,712,439 | BDT 425 |
| January 2026 | 190,917 kg | BDT 77,257,124 | BDT 405 |
| February 2026 | 128,387 kg | BDT 52,006,684 | BDT 405 |
| March 2026 | 111,583 kg | BDT 45,205,040 | BDT 405 |
| April 2026 | 121,008 kg | BDT 40,766,037 | BDT 337 |

Bonded imports. A further 3 kg worth BDT 6,048 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 34 contains 34 tariff lines, averaging 72.25%. At 52%, 34039920 sits below that average by 20.25 percentage points. It is the 17th 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 9.08 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.
