Recorded imports
Between December 2025 and May 2026, NBR recorded commercial imports worth BDT 7,708,704,172 (6,428,070 kg) under this heading, across 27 of its 29 tariff lines. The remaining 2 recorded no commercial import in that window.
NBR's import statements also record 3 codes under this heading that the published Operative Tariff 2026-2027 does not list (84213930, 84213999, 84219900). Those figures are included in the totals above but have no tariff page here, because there is no published rate to show.

Bonded imports. A further BDT 273,314,014 (256,516 kg) entered under the bonded-warehouse regime over the same months — duty-free inputs imported against an undertaking to re-export them. That is 3.4% of the total value imported under this heading.
Import figures: NBR Import Statements (IM-4 commercial, IM-7 bonded), December 2025 – May 2026. Assessable value is the customs value on which duty is charged, not the retail or invoice price.
