Recorded imports

Between December 2025 and May 2026, NBR recorded commercial imports worth BDT 34,955,010,052 (637,394,413 kg) under this chapter, across 163 of its 200 tariff lines. The remaining 37 recorded no commercial import in that window.

NBR's import statements also record one code under this chapter that the published Operative Tariff 2026-2027 does not list (28281000). Those figures are included in the totals above but have no tariff page here, because there is no published rate to show.

Month	Lines with imports	Net weight	Assessable value
December 2025	129	98,324,650 kg	BDT 5,691,185,730
January 2026	122	114,927,114 kg	BDT 7,839,441,576
February 2026	122	108,819,197 kg	BDT 7,184,508,711

April 2026	124	123,534,806 kg	BDT 5,204,458,956
May 2026	123	122,500,059 kg	BDT 4,688,061,716

The largest lines by assessable value in May 2026:

28362000 — Disodium Carbonate — BDT 1,469,884,965
28365000 — Calcium Carbonate — BDT 409,316,957
28363000 — Sodium Hydrogencarbonate (Sodium Bicarbonate) — BDT 265,391,878
28332910 — Zinc sulphate — BDT 264,133,778
28352600 — Other Phosphates Of Calcium, Nes — BDT 231,789,310

Bonded imports. A further BDT 9,037,606,582 (326,480,814 kg) entered under the bonded-warehouse regime over the same months — duty-free inputs imported against an undertaking to re-export them. That is 20.5% of the total value imported under this chapter.

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.
