Recorded imports

Between December 2025 and May 2026, NBR recorded commercial imports worth BDT 129,168,999,650 (29,095,566,891 kg) under this chapter, across 67 of its 79 tariff lines. The remaining 12 recorded no commercial import in that window.

NBR's import statements also record 2 codes under this chapter that the published Operative Tariff 2026-2027 does not list (25210091, 25231020). Those figures are included in the totals above but have no tariff page here, because there is no published rate to show.
