US container imports ended 2025 in a four-month skid that’s likely to lengthen this year as trade shifts to other economies to avoid President Donald Trump’s tariffs, according to a shipping industry analyst’s tally of the country’s top 10 ports. Inbound volumes in December dropped 6.4% from a year earlier to 1.9 million 20-foot container units, after a 5.7% slide the previous month, according to John McCown, who publishes a monthly report that captures flows through America’s biggest gateways for seaborne cargo.
