The Most Comprehensive Analysis of 2025: Why Trump's Tariff Policies Can't Save U.S. E-Commerce? A must-read report for Taiwan's cross-border sellers

The Most Comprehensive Analysis of 2025: Why Trump's Tariff Policies Can't Save U.S. E-Commerce The aggressive tariffs against China announced by the Trump administration and rapidly escalating will not reverse the fundamental dynamics that have led to Chinese sellers dominating the U.S. e-commerce market. Despite promises that the tariffs would help U.S. companies, historical evidence clearly shows that these measures will only result in higher prices for U.S. consumers, while failing to shift market share to domestic sellers.

It's unbelievable! Regardless of changes in tariff policies, the share of Chinese sellers on major U.S. e-commerce platforms continues to grow steadily. Today, more than 50% of Amazon's top sellers are from China, up from less than 40% five years ago. On Walmart, Chinese sellers now account for 28% of all active sellers, up from less than 1% at the beginning of 2021.

Instead of believing that tariffs will solve the problem, it's better to understand the true impact of tariffs.The 2018 tariffs on $283 billion in imports imposed during Trump's first administration, a study by the Journal of Economic Perspectives, found that they were "almost entirely passed on to U.S. domestic prices," meaning that it was U.S. consumers and importers, not Chinese exporters, that were bearing the cost. By December 2018, these tariffs were costing Americans an additional $3.2 billion per month in tax costs and an additional $1.4 billion in economic losses.

The cost advantage over hiring a head manager is a key competitive advantage for Chinese sellers. Chinese sellers have a structural advantage that tariffs cannot address. Many Chinese sellers are manufacturers themselves, or are closer to manufacturing bases than U.S. companies. They also benefit from Chinese government support through export subsidies and tax rebates. What's more, after years of experience on the platform, they have become increasingly proficient in e-commerce operations.

New analysis from e-commerce software provider Threecolts shows that small brands and private label businesses are facing a serious cash crisis, with many unable to afford the unexpected tariff costs of inventory already in transit. The data points to a familiar outcome: U.S. consumers paying higher prices, disruptions in complex supply chains, bankruptcies of domestic sellers, and minimal impact on the market dynamics that led to the dominance of Chinese sellers. The tariffs won't save U.S. e-commerce's market share, but may instead accelerate its decline.
