Shanghai’s Throughput Growth Highlights Where Real Supply Chain Risk Sits

Shanghai Port, the world’s largest container port, handled approximately 46 million TEU in the first ten months of 2025, representing 6.5% year-on-year growth. This compares with overall trade growth of just 3.6% across China, underscoring how strongly container flows through Shanghai continue to perform even as production growth moderates.

For shippers and cargo owners, this is a timely reminder that supply chain resilience is not only about where goods are manufactured. It is equally about which ports and gateways containers move through. While many businesses have adopted “China plus one” sourcing strategies, a large share of container traffic still flows through Shanghai and other major Chinese hub ports.

That concentration brings efficiency, scale, and connectivity, but it also creates exposure. Disruptions at a single mega-hub can have wide-ranging ripple effects across multiple trade lanes, even when manufacturing has been diversified.

Looking ahead to 2026, it is worth reassessing how dependent cargo flows are on a small number of critical ports, and whether shipping routes are flexible enough to adapt if a major hub faces congestion, weather events, regulatory change, or geopolitical pressure. Staying closely engaged with shipping lines, and understanding alternative ports, routings, and vessel options, can help manage both risk and compliance in an increasingly complex environment.

In container shipping, leverage, and vulnerability, often lies less in where goods are produced, and more in where containers actually move from and through.
