At Gain Consulting, we empower U.S. shippers to navigate volatile freight markets with data-driven strategies that optimize costs and efficiency. On June 24, 2025, the Journal of Commerce reported that U.S. West Coast ports, including Los Angeles, Long Beach, and the Northwest Seaport Alliance (NWSA), are bracing for a short-lived cargo surge driven by importers rushing to beat the expiration of temporary tariff relief on July 9 and August 14, 2025. This blog post analyzes the import surge, its implications for U.S. shippers, and actionable strategies to capitalize on this opportunity while preparing for potential disruptions.


Understanding the Tariff-Driven Import Surge

The Trump administration’s temporary tariff relief has spurred a rush of imports, boosting port activity after a weak May and early June. Key details include:

  • Port Volumes:

    • Los Angeles: Projects 138,519 TEUs this week, 124,713 TEUs next week, and 101,003 TEUs for the week of July 6, compared to a May average of 71,000 TEUs/week (PIERS, June 2025).

    • Long Beach: Forecasts 84,109 TEUs this week, 125,286 TEUs next week, and 116,947 TEUs for July 6, up from a May average of 66,000 TEUs/week.

    • NWSA (Seattle/Tacoma): Expects 55 vessel arrivals in June, 49 in July, and 48 in August, up from 46 in May, with fewer blank sailings and additional cargo anticipated (Journal of Commerce, June 24, 2025).

  • Tariff Deadlines: A 90-day tariff reprieve for most U.S. trading partners ends July 9, and relief on China’s 145% tariff expires August 14, prompting the surge.

  • Port Performance: Kip Louttit, executive director of the Marine Exchange of Southern California, noted that vessel arrivals at Los Angeles and Long Beach are at their highest since January 2025 and mid-2024.

  • Rate Trends: Trans-Pacific spot rates dropped to $2,900/FEU for Asia-West Coast, down 10% week-over-week and 50% from a June 6 high of $6,040/FEU (Platts, June 2025).

  • Peak Season Shift: The surge suggests an early peak season (June-July) rather than the typical August-October, with Global Port Tracker forecasting U.S. import declines of 8.1% in July, 14.7% in August, 21.8% in September, and 19.8% in October compared to 2024.

Key Takeaway: The tariff-driven import surge is boosting West Coast port volumes but will be short-lived, with declining rates and an early peak season creating a dynamic environment for shippers.


Contextual Factors Shaping the Import Surge

Several factors amplify the significance of this surge for U.S. shippers:

  1. Tariff Uncertainty: The looming 55% tariff on Chinese imports (Journal of Commerce, June 20, 2025) and lack of a formal U.S.-China trade deal drive importers to front-load shipments.

  2. Freight Market Softness: A lingering freight recession (FreightWaves, June 2025) and LTL shipment declines (6.8% for ODFL, 5% for XPO, 0.4% for Saia, CCJ, June 18, 2025) contrast with the ocean import spike.

  3. E-Commerce Demand: 15% cross-border e-commerce growth in 2024 (U.S. Census Bureau) pressures shippers to meet 68% of consumers’ low-cost shipping expectations (FedEx 2025 E-Commerce Trends Report).

  4. Port Capacity: Weak May volumes (PIERS) ensure West Coast ports can handle the surge without congestion, but post-July declines may strain capacity planning (DAT One, June 2025).

  5. Economic Indicators: The -4.0 Philadelphia Fed Factory Index (Economy in Brief, June 23, 2025) signals stable but cautious manufacturing, impacting inland freight demand.

Key Takeaway: Tariff deadlines, freight market softness, e-commerce growth, port capacity, and economic caution shape the import surge’s impact on shippers.


Implications for U.S. Shippers

The West Coast import surge presents both opportunities and challenges for U.S. shippers:

  1. Increased Freight Volumes: Weekly TEUs exceeding 100,000 at Los Angeles and Long Beach offer opportunities to move goods but require rapid capacity securing.

  2. Cost Pressures: Falling trans-Pacific rates ($2,900/FEU) provide short-term savings, but post-tariff cost hikes (e.g., 55% on China) could raise expenses.

  3. Supply Chain Disruptions: The early peak season and post-July import declines (8.1-21.8%) risk inventory imbalances, challenging just-in-time (JIT) strategies (Supply Chain Management Review, June 2025).

  4. Customer Expectations: Delays or cost pass-throughs may impact 76% of shoppers expecting real-time delivery updates (FedEx), especially in e-commerce.

  5. Capacity Planning Risks: The surge’s short duration and projected import drops require agile adjustments to avoid overstocking or stockouts.

Key Takeaway: Shippers face opportunities from high port volumes and lower rates but must manage cost risks, disruptions, customer expectations, and capacity planning.


Strategic Recommendations for U.S. Shippers

To leverage the import surge and prepare for post-tariff challenges, Gain Consulting recommends the following strategies for U.S. shippers in 2025:

  1. Secure Ocean Capacity Now:

    • Book vessel space immediately with carriers like Maersk or COSCO to capitalize on high TEU weeks (Journal of Commerce, June 24, 2025).

    • Use Freightos to lock in trans-Pacific rates at $2,900/FEU before potential post-tariff spikes.

  2. Optimize Inland Freight:

    • Align LTL and TL capacity with port volumes, using C.H. Robinson’s AI agent for NMFC-compliant tenders (DC Velocity, June 19, 2025).

    • Partner with regional carriers like Estes to manage inland surges (BTS, May 2025).

  3. Balance Inventory Levels:

    • Use AI-driven forecasting like Invent.ai (24/7 Staff, June 2025) to optimize buffer stocks, avoiding overstocking post-July (Global Port Tracker).

    • Implement pool distribution to regional hubs to streamline inventory flow.

  4. Monitor Tariff Deadlines:

    • Track updates via Journal of Commerce and Trump’s social media to prepare for July 9 and August 14, 2025, tariff expirations.

    • Join ASCM webinars for real-time compliance insights (Supply Chain Management Review, June 2025).

  5. Leverage Technology:

    • Adopt TMS platforms like TransImpact to dynamically reroute freight and manage costs, inspired by Amazon’s optimization (24/7 Staff).

    • Use dimensioning tools to ensure NMFC compliance amid LTL declines (CCJ, June 18, 2025).

  6. Enhance Customer Communication:

    • Provide transparent delivery updates to meet 68% of shoppers’ transparency expectations (FedEx), using Gain Consulting’s branded tracking solutions.

    • Notify customers of potential tariff-driven price adjustments to maintain trust.

  7. Diversify Sourcing Strategies:

    • Explore nearshoring to Mexico or Southeast Asia to mitigate 55% Chinese tariff risks, leveraging USMCA benefits (BTS).

    • Partner with Gain Consulting to identify alternative suppliers.

  8. Prepare for Post-Surge Declines:

    • Plan for 8.1-21.8% import drops in July-October (Global Port Tracker) by securing LTL capacity early for Q4 2025 (DAT One).

    • Negotiate volume discounts with carriers like ODFL or XPO to offset costs.

Key Takeaway: Shippers can maximize the surge by securing capacity, optimizing freight, balancing inventory, monitoring tariffs, leveraging technology, communicating effectively, diversifying sourcing, and preparing for import declines.


The tariff-driven import surge, with 138,519 TEUs at Los Angeles and 125,286 TEUs at Long Beach, offers a fleeting opportunity for U.S. shippers, but post-tariff declines loom. Partner with Gain Consulting to build a resilient, cost-effective supply chain that thrives in 2025’s volatile trade landscape.
