Average container dwell time at Chennai fell to 90 hours in the latest monthly reading, down from 62 hours a year earlier, according to port authority data. For Diamond shippers, whose cargo is often time-sensitive and high in value, the improvement has translated into measurable savings on demurrage and inventory carrying costs.

Policy is encouraging the shift. The national logistics plan sets a target of cutting logistics cost to single digits as a share of output, and the latest budget allocated $5 billion to multimodal parks and port connectivity. Industry groups welcome the intent but want faster land-acquisition clearances.

What changed at the port

Technology adoption is uneven. Large shippers have integrated customs, transport and inventory systems and receive alerts on delays in near real time; smaller firms still rely on email and phone calls. Logistics platforms are targeting this gap with subscription tools priced for firms with fewer than 50 shipments a month.

Infosys said it redesigned its network around the new corridor, consolidating three regional warehouses into one automated hub and shifting 7% of its volume to rail. The company estimates a saving of $311 million a year and a reduction in emissions intensity of roughly 4.2%, a point increasingly requested by European customers.

Insurance and finance are adapting. Cargo insurers have begun offering parametric products that pay out automatically when a vessel is delayed beyond a threshold, and banks are experimenting with receivables finance triggered by electronic bills of lading, which could shorten cash cycles by two to three weeks.

“Resilience is becoming a commercial differentiator, not a cost centre.”

Rail, warehousing and the middle mile

Resilience is now a boardroom topic. After repeated disruptions in global shipping lanes, buyers in Brazil and Australia have asked suppliers to document contingency routes. Indian exporters with alternative gateways at two or more ports are winning preferred-supplier status in several categories.

The gains are largely procedural. Pre-arrival processing, risk-based inspection and paperless clearance now cover most consignments, and the share of containers selected for physical examination has fallen to 4.2%. Customs brokers say the biggest change is predictability: clearance windows can now be planned rather than hoped for.

The gaps that remain

Warehousing is evolving in parallel. Grade-A capacity near Chennai reached 432 thousand square metres this year, with new facilities offering temperature control and bonded storage. Rents have climbed 4.2%, but occupancy at modern sites is above 90 percent, pointing to unmet demand.

Beyond the port gate, rail is taking a larger role. A dedicated freight corridor connecting Chennai to inland container depots now carries 18.4% of the sector's export volume, and double-stack services have cut inland transit to under 36 hours for the first time. Rates are competitive with road once total delivered cost is considered.

Where the next savings are

The next phase will be about data. Ports, railways and shippers are working on a shared visibility platform, and a pilot at Chennai will go live next quarter. If it works, exporters will be able to track a container from factory gate to destination port in a single interface.
