A truck from Chennai to Jamshedpur carrying tyres made by Apollo Tyres reached in three and a half days as state border barriers began to be dismantled after the goods and services tax (GST) came into force on July 1. The same truck would have taken five days earlier. Many producers and transport operators are reporting logistics efficiency gains after states abolished border checkposts in the wake of GST, which promises one nation, one tax, one market. As many as 22 have removed barriers and others will do so soon. The time has reduced by nearly 30 per cent as there are no multiple check points and taxes,” said B Krishna Rao, category head at Parle Products. “The initial assessment from our logistics partner is that we are saving at least three days if not more in our supply chain.”
