HS Code 40021100
Latex Of Styrene-Butadiene Or Carboxylated Styrene-Butadiene Rubber
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 40021100 would be approximately BDT 33,630.00, because the Total Tax Incidence is 33.63% of the assessable value.
What these figures mean
Latex Of Styrene-Butadiene Or Carboxylated Styrene-Butadiene Rubber is classified under HS code 40021100, which sits in heading 4002 (Synthetic rubber and factice derived from oils, in primary forms or in plates, sheets or strip; mixtures of heading no. 4001 and 4002, in primary forms or in plates, sheets or strip) of chapter 40 (Rubber and articles thereof).
Under the Bangladesh Operative Tariff 2026-2027 this line attracts Customs Duty of 5%, 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 33.63%, 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 40021100 in 6 of 6 months, totalling 929,663 kg at an assessable value of BDT 162,019,113. That is an average of BDT 174 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 1,500th largest of 4,066 tariff lines by assessable value.

Bonded imports. A further 593,896 kg worth BDT 105,079,810 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 39.3% of the total value imported under this code, the rest entering commercially.

How this line compares
Chapter 40 contains 88 tariff lines, averaging 46.41%. At 33.63%, 40021100 sits below that average by 12.78 percentage points. It is the 58th 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 27.45 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.
