Bangladeshi products exported to India earned $563.96m (TK43.84bn) in fiscal 2012-13, increasing by 13.15% from last year's earnings.
According to estimates by Bangladesh Export Promotion Bureau (EPB), the increase in export revenue meant an additional $65.54m (Tk5.09bn) earned by the country.
Last year, in the same time period, earnings from the sector had come to $498.42m (Tk38.75bn).
Bangladesh is currently India's largest trading partner among the SAARC nations. A press release on the High Commission of India's website says the rise in exports can be attributed to increased access for Bangladeshi products to the Indian market.
This was owing to duty-free and quota-free access for 46 textile tariff lines of "greatest sensitivity" to Bangladesh, announced by India in September, 2011.
Subsequently all products from Bangladesh, except for 25 tariff lines consisting of tobacco, spirits and alcohol, were granted duty-free and quota-free access by India from November of the same year.
The press release said: "Readymade garment exports from Bangladesh to India have seen a significant jump. Item-wise break-up of Bangladeshi exports to India reveal that textile fibres, paper yarn, and woven fabric constitute 23.74% of the exports followed by other man-made textile articles which constitute 13.8%."
"Other items which contribute significantly to the export volumes include edible fruit, nuts, peel of citrus fruit, melons (11.9%), articles of apparel, accessories (10.79%), cotton (4.58%) and copper and copper articles (4.37%)." It stated.
The website said initiatives to improve facilities along the borders, which included establishment of seven Integrated Check Posts, infrastructure development at land ports and custom's stations, and "border haats" (market), all contributed to the increase in trade.
It is expected that these facilities will continue to facilitate trade in both directions, said the press release.
