Maersk Provides Supply Chain Insights Amid U.S. Tariff Changes

April 11, 2025 – Global shipping company Maersk released an industry alert about new U.S. tariff policies, advising clients to prepare for major changes in supply chain costs and customs procedures. According to an April 4 announcement by the U.S. Trade Representative (USTR), the Trump administration began implementing "reciprocal tariffs" on April 5. These tariffs range from 10% to 50% for 60 trading partners, with China-facing combined rates reaching up to 129% (including Section 301 tariffs and IEEPA-related fees).

Key Policy Impacts

Staged Tariff Implementation: Base tariffs (10%) started on April 5. Additional China-specific tariffs (34%) and the end of duty-free treatment for low-value goods (effective May 2) will take effect simultaneously.

Supply Chain Restructuring: U.S. authorities now require Chinese exporters to provide proof of "≥20% U.S. content" for tariff exemptions. Strategic goods like semiconductors and pharmaceuticals must comply with Section 232 regulations.

Global Countermeasures: China raised tariffs on U.S. imports to 84% starting April 10. The EU plans 25% retaliatory tariffs on €21 billion of U.S. products from April 15.

Maersk's Solutions

Customs Compliance: Clients should verify HTS codes early, ensure accurate origin certificates and "U.S. content" declarations to prevent port delays.

Cost Management: The new "Trans-Pacific Emergency Service" (TP11) uses Mexican transshipment to reduce tariffs. A "Tariff Calculator" tool helps estimate total costs.

Cargo Priority: Dedicated "Tariff Fast Lanes" at Los Angeles and New York ports guarantee 48-hour customs clearance for high-tariff goods.

Industry Analysis
The Peterson Institute reports U.S. tariffs have caused a 3.2% drop in global trade volume. Chinese exporters to the U.S. now face over 40% profit margin reductions. Maersk Chief Economist Vincent Clerc stated: "Supply chain resilience must shift from 'efficiency-first' to 'risk management.' Companies need to build alternative production bases in Southeast Asia and Mexico."
