Bonded imports. A further BDT 187,396,788 (735,996 kg) entered under the bonded-warehouse regime over the same months — duty-free inputs imported against an undertaking to re-export them. That is 63.8% of everything imported under this heading: most of this trade never pays the duty rates shown above.
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.
