HS Code 73052000
Iron/Steel Casing For Drilling For Oil Or Gas, >406.4mm External Diameter
Worked example
On an assessable value of BDT 100,000, the total duty and taxes payable on 73052000 would be approximately BDT 64,250.00, because the Total Tax Incidence is 64.25% of the assessable value.
What these figures mean
Iron/Steel Casing For Drilling For Oil Or Gas, >406.4mm External Diameter is classified under HS code 73052000, which sits in heading 7305 (Iron or steel (excluding cast iron); tubes and pipes (e.g. welded, riveted or similarly closed), having circular cross-sections, external diameter of which exceeds 406.4mm, not seamless) of chapter 73 (Articles of iron or steel).
Under the Bangladesh Operative Tariff 2026-2027 this line attracts Customs Duty of 25%, Supplementary Duty of 0%, VAT of 15%, Advance Income Tax of 5%, Regulatory Duty of 5% and Advance Tax of 7.5%. Combined, these produce a Total Tax Incidence of 64.25%, 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.

Between February 2026 and February 2026, NBR recorded commercial imports under 73052000 in 1 of 6 months, totalling 21,920 kg at an assessable value of BDT 9,996,472. That is an average of BDT 456 per kilogram — useful as a rough check on whether a declared value looks plausible. In February 2026 it was the 1,714th largest of 4,051 tariff lines by assessable value.
