US Port System: Scale & Investment

• In 2023, U.S. ports handled 743 million tons of cargo and accounted for 41.5% of the value in U.S. international trade—about $2.1 trillion.
• Over 21.8 million U.S. jobs are supported by maritime commerce.
• Under the 2021 Infrastructure Investment & Jobs Act, federal funding for ports nearly doubled: $450 million annually to better develop waterside and landside infrastructure.
• Ongoing challenges include dredging needs, rising sea levels (+10–12 inches projected in 30 years), and climate-driven disruptions.

‍

Trade Routes & Operational Dynamics

• West Coast congestion surged 20–30% in 2024 due to reshoring trends and alliance shifts—triggering blank sailings and delays
• East and Gulf Coast ports are seeing increasing import share, rising to 44.6% of national TEU volume by May 2024.
• U.S.–China trade remains key: May 2024 saw 890,760 TEUs of Chinese-origin goods—up 17.6% from April.
• Policy volatility persists: recent Trump-era tariff threats have caused volume dips of up to 35% at LA and Long Beach .
