HS Code 35071000
Rennet And Concentrates Thereof
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 35071000 would be approximately BDT 39,750.00, because the Total Tax Incidence is 39.75% of the assessable value.
What these figures mean
Rennet And Concentrates Thereof is classified under HS code 35071000, 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 10%, 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 39.75%, 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 35071000 in 2 of 6 months, totalling 8 kg at an assessable value of BDT 140,498. That is an average of BDT 17,562 per kilogram — useful as a rough check on whether a declared value looks plausible. In April 2026 it was the 4,105th largest of 4,161 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |
|---|---|---|---|
| December 2025 | 7 kg | BDT 139,762 | BDT 19,966 |
| April 2026 | 1 kg | BDT 736 | BDT 736 |
Bonded imports. A further 28,405 kg worth BDT 12,412,895 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. That is 98.9% of everything imported under this code. In practice this line is an export input rather than a product entering the domestic market, so the duty rates above apply to only a small fraction of the trade.

How this line compares
Chapter 35 contains 18 tariff lines, averaging 46.79%. At 39.75%, 35071000 sits below that average by 7.04 percentage points. It is the 7th 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 21.33 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.
