HS Code 35079010
Streptokinase
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 35079010 would be approximately BDT 5,000.00, because the Total Tax Incidence is 5% of the assessable value.
What these figures mean
Streptokinase is classified under HS code 35079010, which sits in heading 3507 (Enzymes; prepared enzymes not elsewhere specified or included) of chapter 35 (Albuminoidal substances; modified starches; glues; enzymes).
Under the Bangladesh Operative Tariff 2026-2027 this line attracts Customs Duty of 0%, Supplementary Duty of 0%, VAT of 0%, Advance Income Tax of 5%, Regulatory Duty of 0% and Advance Tax of 0%. Combined, these produce a Total Tax Incidence of 5%, 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 35079010 in 6 of 6 months, totalling 91 kg at an assessable value of BDT 49,023,576. That is an average of BDT 538,721 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 1,403rd largest of 4,066 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |
|---|---|---|---|
| December 2025 | 24 kg | BDT 85,495 | BDT 3,562 |
| January 2026 | 6 kg | BDT 80,364 | BDT 13,394 |
| February 2026 | 16 kg | BDT 10,486,505 | BDT 655,407 |
| March 2026 | 2 kg | BDT 20,900 | BDT 10,450 |
| April 2026 | 21 kg | BDT 25,569,295 | BDT 1,217,585 |
| May 2026 | 22 kg | BDT 12,781,017 | BDT 580,955 |
Bonded imports. A further 36,800 kg worth BDT 11,133,317 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 18.5% of the total value imported under this code, the rest entering commercially.

How this line compares
Chapter 35 contains 18 tariff lines, averaging 46.79%. At 5%, 35079010 sits below that average by 41.79 percentage points. It is the 18th 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 56.08 points.
Within heading 3507 alone, rates run from 5% to 39.75% across 3 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.
