HS Code 38109010
Pickling preparations for metal surface....Submerge welding flux for LPG
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 38109010 would be approximately BDT 33,630.00, because the Total Tax Incidence is 33.63% of the assessable value.
What these figures mean
Pickling preparations for metal surface....Submerge welding flux for LPG is classified under HS code 38109010, which sits in heading 3810 (Metal-pickling preparations; fluxes etc for soldering, brazing; welding powders, pastes of metal and other materials; preparations used as cores or coatings for welding electrodes or rods) of chapter 38 (Miscellaneous chemical products).
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 38109010 in 6 of 6 months, totalling 118,729 kg at an assessable value of BDT 13,809,905. That is an average of BDT 116 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 2,497th largest of 4,066 tariff lines by assessable value.

Bonded imports. A further 400 kg worth BDT 1,506,756 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 9.8% 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 33.63%, 38109010 sits below that average by 10.25 percentage points. It is the 115th 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.
Within heading 3810 alone, rates run from 33.63% 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.
