Core Viewpoint - The U.S. International Trade Commission (ITC) has determined that imports of hexamethylenetetramine (hexamine) from China cause substantial harm to the U.S. industry, leading to the implementation of anti-dumping (AD) and countervailing duties (CVD) on these products [1] Group 1: Tariff Impact - The final ruling by the U.S. Department of Commerce on July 15, 2025, established a high anti-dumping rate of 405.19% and a countervailing duty rate of 420.73%, resulting in a combined tariff burden of 825.92% [2][3] - This exceptionally high tariff effectively eliminates the competitiveness of Chinese hexamine in the U.S. market, making direct export economically unfeasible [2][3] Group 2: Global Investigation Context - The current measures are part of a broader investigation initiated in October 2024, which included anti-dumping investigations against hexamine from China, Germany, India, and Saudi Arabia, as well as countervailing duty investigations against China and India [5] - Chinese exporters have been identified as facing the highest tariff rates, indicating a strategic move to protect the U.S. domestic hexamine industry from import competition [5] Group 3: Transshipment Trade - In light of the high tariffs, some exporters are considering transshipment through third countries, such as Turkey, to circumvent the direct application of the "double anti" tariffs [6][8] - The transshipment process involves normal customs clearance and tax refunds in China, followed by re-invoicing and container changes in Turkey before exporting to the U.S. under Turkish origin [7] Group 4: Future Trends and Industry Impact - Hexamine is a fundamental chemical raw material with significant demand in plastics, pharmaceuticals, and rubber, making complete reliance on domestic production unlikely for the U.S. [10] - The "double anti" measures are expected to persist in the coming years, compelling Chinese exporters to rely on transshipment trade to maintain market share [10] - As the U.S. enhances source tracing regulations, compliance and documentation will be critical for companies using transshipment methods to avoid new trade risks [10]
