HS Code 85371010
BUSBAR TRUNKING SYSTEM
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 85371010 would be approximately BDT 28,730.00, because the Total Tax Incidence is 28.73% of the assessable value.
What these figures mean
BUSBAR TRUNKING SYSTEM is classified under HS code 85371010, which sits in heading 8537 (Boards, panels, consoles, desks, cabinets, bases with apparatus of heading no. 8535, 8536 for electricity control and distribution, (other than switching apparatus of heading no. 8517)) of chapter 85 (Electrical machinery and equipment and parts thereof; sound and television recorders and reproducers).
Under the Bangladesh Operative Tariff 2026-2027 this line attracts Customs Duty of 1%, 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 28.73%, 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 85371010 in 6 of 6 months, totalling 1,070,867 kg at an assessable value of BDT 1,752,878,587. That is an average of BDT 1,637 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 325th largest of 4,066 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |
|---|---|---|---|
| December 2025 | 165,709 kg | BDT 281,856,439 | BDT 1,701 |
| January 2026 | 159,640 kg | BDT 298,793,937 | BDT 1,872 |
| February 2026 | 164,754 kg | BDT 304,080,381 | BDT 1,846 |
| March 2026 | 129,822 kg | BDT 199,353,858 | BDT 1,536 |
| April 2026 | 330,101 kg | BDT 518,472,597 | BDT 1,571 |

Bonded imports. A further 80,780 kg worth BDT 145,462,532 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 7.7% of the total value imported under this code, the rest entering commercially.

How this line compares
Chapter 85 contains 412 tariff lines, averaging 52.09%. At 28.73%, 85371010 sits below that average by 23.36 percentage points. It is the 338th 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 32.35 points.
Within heading 8537 alone, rates run from 28.73% to 39.75% across 4 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.
