March U.S. Container Imports Climb as Global Supply Chain Pressures Mount in Port News 10/04/2026 In March 2026, U.S. containerized imports increased 12.4% from February to a total of 2,353,611 twenty-foot equivalent units (TEU) and decreased 1.1% compared to March 2025. The rebound follows a typical seasonal pattern after February’s decline, with volumes remaining well above pre-pandemic levels, indicating continued resilience in underlying demand despite ongoing policy and economic uncertainty. China-origin imports continued to trend downward in March, declining 2.3% month-over-month and remaining more than 30% below their July 2024 peak. While sourcing diversification toward Southeast Asia and other regions persists, overall imports from the top 10 countries of origin declined just 1.4% year-over-year, suggesting relatively stable global sourcing demand despite ongoing shifts in trade patterns. The broader trade environment has become increasingly complex. Escalating tensions in the Middle East have significantly disrupted global shipping, with the Strait of Hormuz effectively restricted and rising threats to the Bab al-Mandeb Strait, linking the Red Sea to the Gulf of Aden and on to the Indian Ocean, increasing risk across key maritime corridors. Heightened security concerns, vessel rerouting, and rising costs continue to affect shipping, though a ceasefire announced on April 7 may offer tentative signs of stabilization if it holds. At the same time, U.S. tariff policy remains in flux following February’s Supreme Court ruling and implementation of temporary Section 122 tariffs, while trade negotiations and agreements remain uncertain, including stalled U.S.–India talks, pending U.S.–EU agreement implementation, and potential U.S.–China negotiations. Together, these dynamics reinforce a global trade environment defined by volatility and uncertainty. U.S. container imports post strong seasonal rebound in March, following February’s dip. U.S. containerized imports totaled 2,353,611 TEUs in March 2026, up 12.4% month-over-month and down a slight 1.1% compared to March 2025 (see Figure 1). The March rebound suggests typical seasonal patterns at play following February’s decline, with volumes reflecting steady demand despite ongoing policy uncertainty. Volumes remained significantly elevated relative to pre-pandemic levels, standing 32.3% above March 2019. Year-to-date imports trail 2025 levels by 4.8%. While observing the seasonal trend of month-over-month increases, February-to-March 2026 marks the strongest increase in recent years (see Figure 2). March import volume was also the fourth highest on record for the month, trailing March 2022 by 204,410 TEUs, March 2021 by 172,744 TEUs, and March 2025 by 27,063 TEUs, suggesting stable import activity. Volumes at top 10 U.S. ports rebound in March. Container volumes across the top 10 U.S. ports increased by 193,294 TEUs in March 2026, an 11.0% month-over-month gain (see Figure 3). Performance across individual ports was broadly positive, with gains reported at eight of the ten major gateways. New York/Newark recorded the largest increase, rising 37.3% (100,875 TEUs), followed by Norfolk, up 35.4% (38,091 TEUs). Additional strong gains were observed at Oakland (25.5%), Charleston (24.2%), Houston (19.1%), Miami (15.4%), and Savannah (13.0%). Los Angeles was the only port to post a significant decline, falling 11.0% (46,662 TEUs). China-origin imports weaken further in March with broad catego
