Core Viewpoint - The article discusses the impact of the recent tariff reductions between China and the United States on the trade dynamics in Yiwu, a major hub for small commodity exports.

Summary by Sections Tariff Adjustments - On May 14, the U.S. and China implemented reciprocal tariff reductions, with the U.S. canceling 91% of tariffs on Chinese goods and suspending 24% of a 34% tariff for 90 days, while China reciprocated similarly [3][4]. - The U.S. also reduced tariffs on small packages from China, lowering the international mail tax rate from 120% to 54% [3]. Trade Volume Surge - Following the tariff reductions, container shipping bookings from China to the U.S. surged nearly 300%, with a seven-day average booking volume increasing by 277% to 21,530 standard containers [4][3]. Yiwu's Trade Performance - Yiwu's total import and export value reached 668.93 billion yuan in 2024, marking an 18.2% year-on-year increase, with exports at 588.96 billion yuan (up 17.7%) and imports at 79.97 billion yuan (up 22.2%) [7].

Varied Business Experiences - Different businesses reported varied impacts from the tariff changes. Some, like a seller of Christmas decorations, experienced increased production demands, while others faced delays or cancellations from U.S. clients due to previous tariff uncertainties [10][12]. - A portion of businesses expressed confidence that the tariff reductions would eventually lead to increased orders, while others remained unaffected due to their limited exposure to the U.S. market [14][15]. Broader Economic Implications - The easing of trade tensions between the U.S. and China is expected to have significant implications for global supply chains, potentially restoring stability and efficiency that had been disrupted by previous tariff conflicts [16].
