美关税重锤砸向加墨：北美产业链的裂变与重构

Group 1: Automotive Manufacturing Chain Risks - The U.S. plans to tighten local content rules, increasing the domestic parts localization rate from 75% to 80%, creating a dilemma for Chinese auto parts manufacturers in Mexico [1] - In Mexico, there is a significant investment surge with $1.45 billion in Q1 2025, a 134% year-on-year increase, but hidden costs are becoming apparent [3] - The cost structure comparison shows that labor costs in the nearshore model in Mexico are 180% of traditional models, while compliance costs are higher due to USMCA origin verification requirements [3] Group 2: Energy Alliance Restructuring - The U.S. imposes a 10% tariff on imported mineral fuels, which constitutes 51.9% of U.S. imports, pressuring Chinese energy companies to accelerate LNG terminal construction and shift focus to Japan and South Korea, despite a 25% increase in transportation costs [2] - Chinese companies are also looking to process shale gas in Mexico, utilizing the tax-free zone at the U.S.-Mexico border to shift production capacity [2] - U.S. supply chain scrutiny is increasing, requiring rare earth companies to prepare comprehensive production evidence [2] Group 3: Export Strategies for U.S. Exporters - Tax base optimization strategies include using offshore companies for multi-layer transactions and splitting vehicle exports into parts to benefit from lower tariffs on intermediate goods [5] - Market access strategies involve leveraging Kazakhstan's auto parts park and utilizing UAE free trade zones for re-labeling to obtain "Arabian-made" certificates [5] - Technology-intensive companies are converting tariff costs into R&D investments and obtaining EU carbon footprint certifications to avoid carbon tariffs while achieving a 15% premium [5] Group 4: Broader Implications - The conflict illustrates the harsh reality that in the "G0 era" of de-globalization, supply chain resilience is no longer based on tight interdependence but rather on redundant backups to withstand turmoil [7] - The North American free trade ideal is being fragmented by zero-sum games, as Mexico finds itself caught between U.S. tariff wars and nearshore outsourcing opportunities [7]
