He said this at a press conference at the VIP lounge of Dhanmondi Club in the capital on Wednesday.
Tanners and leaders of the organisation also present at the press conference.
Shahin told the press conference that some 350,000 pieces of rawhide have been collected by the tanners in the last three days.
He hoped to collect 9.5 million pieces of rawhide of cows, buffaloes, goats and sheep.
The BTA president also said that chemicals are required for processing rawhides. Tanners will collect the chemicals under supervised bond facility.
“For the interest of the tannery industry, it is necessary to maintain supervised bonds and increase the scope of its benefits. BTA has already applied to the National Board of Revenue to increase this facility,” he said.
