With the August 2025 reciprocal tariff updates, U.S. importers – especially in the automotive sector – face new cost structures that demand proactive planning
Introduction
As global trade dynamics shift, staying ahead of policy changes is critical for maintaining a competitive supply chain. The latest update to U.S. reciprocal tariffs, effective August 2025, carries significant implications for U.S. importers of all goods, including automotive components and especially brake drums. Our experts have put together a complete breakdown of what’s changed and how TBP Auto’s Vietnam-based manufacturing can help you stay ahead.
Understanding Reciprocal Tariffs
Unlike WTO-bound tariffs, which are based on multilateral agreements and most-favored-nation (MFN) principles, reciprocal tariffs are imposed unilaterally by the United States to address perceived trade imbalances on a country-by-country basis.
Each country now faces unique tariff rates depending on the status of their bilateral trade agreements with the United States. For brake drum manufacturers exporting to the U.S., this means an increase in total import costs, varying considerably by country of origin.
U.S. Tariffs on Vietnamese Exports
On July 31, 2025, the United States issued an executive order modifying the reciprocal tariff rates applied to imports from Vietnam and other trading partners. The new framework, which takes effect August 7, 2025, introduces key changes across two annexes:
Annex I: Modified Country-Based Tariff Rates
Vietnam has been assigned a 20% reciprocal tariff rate under Annex I. This applies to most general goods and reflects Vietnam’s status as a country with a trade surplus relative to the U.S. Countries with a surplus face a minimum 15% rate, while those with a U.S. trade deficit enjoy a lower 10% baseline.
Annex II: Harmonized Tariff Schedule Adjustments
Annex II details product-specific tariffs. While Vietnam faces the 20% rate for most items, certain sectors are excluded from these tariffs, including:
- Pharmaceuticals
- Semiconductors
- Critical minerals
- Energy-related products
- Copper and lumber items
Goods already in transit before 12:01 a.m. ET on August 7 and arriving before October 5, 2025, may qualify for a temporary transit exemption.
Enforcement Measures: Anti-Transshipment Provisions
To prevent tariff circumvention, the U.S. Customs and Border Protection (CBP) will apply a 40% duty on goods found to be transshipped through third countries. Importers in violation may face additional penalties under U.S. customs law, with no option for mitigation.
Country-Specific Reciprocal Tariff Recap
The new tariff structure sets distinct rates for each country. Below is a full list of the country-specific updated reciprocal tariff for general imports:

Strategic Implications for U.S. Importers
These global tariff hikes represent a meaningful shift in trade costs, but its overall impact will depend on how importers adapt. For some, this change may gradually tighten margins; for others, it serves as a timely opportunity to reassess supplier relationships and supply chain resilience. Many U.S. importers and distributors have been carefully reconsidering their approach.
Vietnam, despite now facing a 20% tariff, continues to stand out as one of the most reliable sourcing destinations in Asia, positioned advantageously compared to countries facing higher tariffs. Its strong compliance infrastructure, transparent customs documentation, and stable trade relations offer distinct advantages over higher-risk markets.
For importers prioritizing long-term stability and regulatory alignment, Vietnam remains:
- Predictable – Low risk of future trade penalties or enforcement actions
- Transparent – Clear rules-of-origin documentation and customs compliance
- Compliant – Fully auditable supply chains that mitigate transshipment risk
As tariff enforcement tightens, origin traceability and proactive planning are no longer optional – they’re essential to protecting margins and avoiding costly disruptions.
