I have never seen any brain less people like you who has no knowledge what is happening at the border and come here for posting what propaganda news of India feed you lot.
It does not require trucks as it happens openly by people of both side of the border and by giving bribe to BSF. So no customs is involved here.
Even the following propaganda Indian news admitted there are 2.7 billion usd worth of smuggling happen at the border.

The following news which is from a reputable news media gives more detail picture.

`Imitaz Ahmed explains: "Statistics show to India’s favor.
There is 3.2 billion dollars of informal trade or Indian smuggled goods coming to Bangladesh. Bangladesh’s smuggled goods going to India amount to around 300 to 400 million dollars, that’s almost similar to the formal trade." He adds, "Bangladesh did not agree on the zero line, so fences are built inside Indian borders.
So these 3.5 billion dollars worth of Indian goods have to pass the Indian fences first, so critics do point out that that is some kind of a state sponsored smuggling."
Hope this will help you to enlighten your ignorance.
