HS Code 29181100
Lactic Acid, Its Salts And Esters
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 29181100 would be approximately BDT 33,630.00, because the Total Tax Incidence is 33.63% of the assessable value.
What these figures mean
Lactic Acid, Its Salts And Esters is classified under HS code 29181100, which sits in heading 2918 (Acids; carboxylic acid with additional oxygen function and their anhydrides, halides, peroxides, peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives) of chapter 29 (Organic chemicals).
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 29181100 in 6 of 6 months, totalling 443,612 kg at an assessable value of BDT 105,810,259. That is an average of BDT 239 per kilogram — useful as a rough check on whether a declared value looks plausible. In May 2026 it was the 1,574th largest of 4,066 tariff lines by assessable value.
| Month | Net weight | Assessable value | Per kg |
|---|---|---|---|
| December 2025 | 46,300 kg | BDT 15,443,941 | BDT 334 |
| January 2026 | 104,851 kg | BDT 27,901,678 | BDT 266 |
| February 2026 | 32,502 kg | BDT 8,127,890 | BDT 250 |
| March 2026 | 119,351 kg | BDT 31,405,188 | BDT 263 |
| April 2026 | 76,308 kg | BDT 13,211,323 | BDT 173 |
| May 2026 | 64,300 kg | BDT 9,720,239 | BDT 151 |
Bonded imports. A further 290 kg worth BDT 53,708 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 0.1% of the total value imported under this code, the rest entering commercially.

How this line compares
Chapter 29 contains 491 tariff lines, averaging 36.78%. At 33.63%, 29181100 sits below that average by 3.15 percentage points. It is the 229th 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 2918 alone, rates run from 33.63% to 39.75% across 17 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.
