The Northwest Seaport Alliance recorded September 2026 total container volume of 265,692 TEUs, down 8.1% compared to September 2025, with full imports down 4.4% and full exports declining 9.6% year-on-year.

However, on a month-on-month basis September delivered a significant sequential improvement, with full imports up 21.5% and full exports up 24.2% over August, indicating strengthening momentum heading into the final quarter of the year.

Year-on-year declines continue to reflect the elevated 2025 baseline established when cargo was shipped ahead of anticipated tariff changes.

Year-to-date through September, total volumes reached 2,174,231 TEUs, down 10.6 percent, with full imports declining 12.2% and full exports down 2.3%.
