India’s greatest tax reform — replacing an array of provincial duties with a nationwide goods and services tax — is transforming the logistics industry in a country where moving stuff around is notoriously difficult to do, executives say. The advent of organised retail and e-commerce began modernising warehouses in India a decade ago, but most firms still rely on musty, dilapidated “godowns”, as storehouses are known colloquially.The unified tax system is expected to bring change on a far grander scale, removing distortions created by differential taxes and duty structures imposed across India’s 29 states and 7 union territories.“When we moved from one state to the other, it felt like moving from one country to another,” said Ramesh Agarwal, chairman of New Delhi-based Agarwal Packers and Movers.From July 1, the new Goods and Services Tax, or GST, introduced by Prime Minister Narendra Modi’s government, will change all that, with the biggest tax reform seen since India won independence from British colonial rule 70 years ago.Companies that have previously based storage models on tax efficiency can move to the much more cost efficient, demand-based hub-and-spoke model used globally.

So decisions on manufacturing, warehousing and selling will be purely driven by the real costs of manufacturing and going to market, that is the single biggest advantage of GST,” said R Subramanian, Managing Director at DHL Express in Mumbai.Subramanian still anticipates bureaucratic headaches, notably from GST’s e-way bill system, requiring vehicle details from pickup to delivery, which he reckons would generate 90 million entries daily for the express delivery sector alone.But, the reform, along with the gradual shift in India’s service dominated economy toward more manufacturing, has paved the way for ultra-modern storage sites with automated conveyers, RFID-enabled tracking and IT-enabled warehousing management systems. The potential growth, and investment needed for modernisation has spurred a slew of deals between Indian firms and major global private equity players and pension funds.In the last two years alone, as Modi made GST a priority, these investors have put $1.5 billion in the warehousing business. “GST is not only a tax reform, it is also a business reform as a whole, and a lot of businesses are now restructuring their supply chains,” said Rohit Jain, a partner with Economic Laws Practice in Mumbai.Read: Will GST untangle India’s tax regime? How the new system might impact consumers and businessesReplacing GodownsCanada Pension Plan Investment Board last month committed to spend $500 million in a joint venture with India’s IndoSpace. Other foreign firms putting money in the sector include Carlyle Group, Warbug Pincus and Fairfax India Holdings .JSW Steel, India’s biggest domestic steel producer, is also mulling a plan to bring down the number of its 20 plus warehouses across the country to five, and many more companies are following suit, said a company executive.Reliance Retail, the retail unit of Reliance Industries , which has around 100 distribution centres across the country, also plans to “optimize some,” said a company executive.Mahindra Logistics is exploring an initial public offering, or a sale to a foreign partner, while rival Future Supply Chain Solutions is looking to do likewise, according to media reports.Read — GST ready for June 30 midnight launch: The anatomy of a unified tax regimeWith 45% of India’s gross domestic product concentrated around seven major cities, Arif A Siddiqui at Coign Consulting, specialising in supply chain management, expected investment in warehousing to focus on Ahmedabad, Bengaluru, Chennai, Hyderabad, Kolkata, Mumbai, and New Delhi. Singapore-based logistics company Ascendas-Singbridge has just signed a $600 million deal with Firstspace Realty, based in the south Indian city of Bengaluru, to create 14 million square feet (1.3 million square meters) of industrial warehousing space across six major Indian cities.“Manufacturing, modern retail and the pharma sector were already driving change in Indian warehousing. GST has just fast-tracked the growth rate in logistics,” said Aloke Bhuniya, Chief Executive of Ascendas-Firstspace.He reckoned that GST has boosted the industry’s annual growth rate from 12-15% to 20-22%, and saw plenty of room for a lot more modernisation.Out of the logistics industry’s 980 million square feet (91 million square meters) of captive, agri-based and cold storage warehousing, Bhuniya estimated 85 percent were old godowns and traditional structures.“This represents a huge opportunity for modern warehousing to tap into,” he said.
