Green-chilli imports from India began entering Bangladesh through the Bhomra and Benapole land ports on 3 August.
Bhomra Customs Commissioner Md Mostafizur Rahman said 10 trucks carrying about 100 metric tonnes had entered through the Satkhira port by the evening.
He said importers would distribute the chillies to markets around the country after completion of customs and duty procedures.
At Benapole, a truck delivered 9,200kg of green chillies, and the consignment was dispatched toward Dhaka after clearance formalities.
Benapole port director Shamim Hossain said clearance for the truck was completed quickly and additional chilli-laden trucks were waiting across the border.
Traders and agricultural authorities described the imports as a measure to increase supply and curb high consumer prices.
Rajab Ali, general secretary of Satkhira's fresh-produce traders' association, said persistent rain had submerged chilli fields in and around the district, damaging crops and reducing vegetable production.
He said green chillies that had sold for about Tk50 per kg in Satkhira roughly 15 days earlier were selling above Tk300 per kg.
A Benapole importer, Shahajan, said his import cost was about Tk135 per kg and that he intended to sell with a small margin.
Shahajan alleged that customs and clearance complications were increasing import costs.
Importers and traders said prices could fall if imports continue and market supply rises, but no post-import retail price reduction was established.
