1. Policy Core and Transmission Pathways

1. Tariff Structure and Scope

   • The U.S. imposed a 46% tariff on Vietnamese goods (reaching 61%-62% when combined with existing rates), covering critical categories such as textiles, footwear, electronics, and furniture, directly impacting approximately 35% of Vietnam’s export value16.

   • The policy uses a "minimum baseline tariff" mechanism to require trade partners to match U.S. tariffs, triggering punitive rates otherwise, thereby reshuffling about 20% of global maritime trade volume.

2. Supply Chain Reconfiguration Logic

   • Short-Term Rush and Inventory Backlog: Vietnam’s container exports to the U.S. fell 15% MoM in February 2025, but rebounded temporarily in March due to panic buying, with the Shanghai-U.S. West Coast freight index surging 18.4% weekly1.

   • Long-Term Industrial Relocation: Companies like Nike and Samsung are shifting production to Mexico and Southeast Asia, with Vietnam’s direct exports to the U.S. projected to drop from 75% to 55% by 2025, while transshipment trade rises to 30%623.

2. Multidimensional Impacts on Vietnam’s Maritime Shipping

1. Trade Volume and Route Patterns

• Decline in Trans-Pacific Routes:

  • The Port of Los Angeles forecasts a 12% container throughput drop in H2 2025, with global U.S.-related maritime demand declining 15%-20%, and Vietnam’s container exports to the U.S. potentially falling 20%-25%120.

  • China-Europe rail freight serves as an alternative, with a 22.9% YoY increase in departures in Jan-Feb 2025, and "Belt and Road" hubs like Lianyungang seeing 8.49% container volume growth1.

• Regional Route Divergence:

  • Intra-Asia routes grew 8%-12%, with Vietnam launching new services to Laem Chabang, Thailand, cutting transit time by 40%111.

  • Mexico-to-U.S. East Coast volumes are projected to rise 30%, with some Vietnamese firms using "Mexico transit" to bypass tariffs, driving a 15%-20% throughput increase in Central American ports122.

2. Freight Rates and Cost Volatility

• Short-Term Rate Rebound:

  • U.S.-bound spot rates surged 18.4% MoM in March due to panic buying and Red Sea detours, while Europe-bound rates stabilized with a 13.6% decline1.

  
  

• Long-Term Downward Pressure:

  • If U.S.-bound demand falls 15%-20% annually, global container demand growth may slow to 1%-1.4%, widening supply-demand gaps and pressuring Vietnamese shipping firms’ gross margins120.

  
  

3. Port and Capacity Adjustments

• Hub Port Divergence:

  • Ho Chi Minh City Port handled 18 million TEU in 2024, but U.S.-bound throughput is projected to drop 15%-20% in 2025, with transshipment cargo rising to 45%717.

  • Haiphong Port optimized operations via "container-to-bulk" direct loading, achieving 8.49% container volume growth1.

• Structural Capacity Contraction:

  • Carriers delayed vessel deliveries and increased blank sailings (e.g., 2 weekly blank voyages on Far East-North Europe routes), redirecting capacity to Europe or intra-Asia115.

4. Corporate Strategies and Compliance Challenges

• Supply Chain Adjustments:

  • Vietnamese shipping firms shifted 30% of capacity to Southeast Asia-Middle East routes, with regional revenue exceeding 35%; some adopted blockchain for faster customs clearance126.

  
  

• Rising Compliance Costs:

  • Electronics require INMETRO certification, food/pharmaceuticals need ANVISA approval, and cross-border e-commerce parcels (under $800) lose tax exemptions, complicating logistics by 30%120.

  
  

3. Industry Responses and Future Challenges

1. Policy Countermeasures and Market Diversification

   • Vietnam imposed a 24% tariff on U.S. imports and implemented 12 countermeasures, including rare earth export controls and anti-dumping investigations, directly impacting U.S. agricultural and energy imports113.

   • Trade with ASEAN expanded via RCEP, with Vietnam’s exports to ASEAN growing 6.8% in Jan-Feb 2025, accounting for 16.1% of total trade1.

2. Shipping Enterprise Transformations

   • Cost Control: Vietnamese firms reduced unit costs via digitalization, with 2024 operating costs rising only 12.3% vs. revenue growth of 33.3%1.

   • Green Transition: Carriers accelerated LNG and biofuel adoption, with green fuel demand projected to grow 40% by 2025, though costs remain 3-4x traditional fuels125.

3. Long-Term Structural Risks

   • Geopolitical Uncertainty: U.S. proposed port access fees ($1.5 million per vessel) for Chinese ships, potentially increasing costs by 15%-20% if implemented1.

   • Global Trade Fragmentation: Supply chain "regionalization" reduces long-haul demand, requiring Vietnam to balance U.S. route contraction with emerging market growth125.
