HS Code 38121000
Prepared Rubber Accelerators
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 38121000 would be approximately BDT 39,750.00, because the Total Tax Incidence is 39.75% of the assessable value.
What these figures mean
Prepared Rubber Accelerators is classified under HS code 38121000, which sits in heading 3812 (Prepared rubber accelerators; compound plasticisers for rubber or plastics, n.e.c. or included; anti-oxidising preparations and other compound stabilisers for rubber or plastics) of chapter 38 (Miscellaneous chemical products).
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 May 2026, NBR recorded commercial imports under 38121000 in 6 of 6 months, totalling 314,403 kg at an assessable value of BDT 106,675,115. That is an average of BDT 339 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 1,544th largest of 4,066 tariff lines by assessable value.

Bonded imports. A further 131,632 kg worth BDT 56,789,514 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 34.7% of the total value imported under this code, the rest entering commercially.

How this line compares
Chapter 38 contains 139 tariff lines, averaging 43.88%. At 39.75%, 38121000 sits below that average by 4.13 percentage points. It is the 41st 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 3812 alone, rates run from 35.75% to 45.88% across 5 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.
