Average container dwell time at Chennai fell to 45 hours in the latest monthly reading, down from 62 hours a year earlier, according to port authority data. For Water Resources shippers, whose cargo is often time-sensitive and high in value, the improvement has translated into measurable savings on demurrage and inventory carrying costs.

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.

What changed at the port

Warehousing is evolving in parallel. Grade-A capacity near Chennai reached 1,747 thousand square metres this year, with new facilities offering temperature control and bonded storage. Rents have climbed 11.9%, but occupancy at modern sites is above 90 percent, pointing to unmet demand.

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 11.9%. Customs brokers say the biggest change is predictability: clearance windows can now be planned rather than hoped for.

Beyond the port gate, rail is taking a larger role. A dedicated freight corridor connecting Chennai to inland container depots now carries 26.8% 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.

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

Rail, warehousing and the middle mile

Not every link has kept pace. Last-mile trucking remains fragmented, with small operators accounting for most capacity and little data sharing. Several exporters reported that goods cleared in 24 hours then waited three days for a truck, eroding much of the benefit achieved upstream.

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 $7.2 billion to multimodal parks and port connectivity. Industry groups welcome the intent but want faster land-acquisition clearances.

The gaps that remain

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.

Sun Pharma said it redesigned its network around the new corridor, consolidating three regional warehouses into one automated hub and shifting 18.1% of its volume to rail. The company estimates a saving of $362 million a year and a reduction in emissions intensity of roughly 11.9%, a point increasingly requested by European customers.

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.
