The United States continues to apply Section 301 tariffs on synthetic rubbers, placing liquid diene imports from China under a 25% duty since August 1, 2024, as part of List 3 measures that target rubbers, plastics, and other polymers imported from the People’s Republic of China. These tariffs reinforce a protectionist environment that has persisted for several years, requiring importers to absorb higher landed costs or negotiate alternative supply routes.

In parallel, a landmark Executive Order issued on April 2, 2025 closed the duty-free de minimis exemption for low-value shipments from China and Hong Kong effective May 2, 2025, subjecting previously exempted parcels under $800 to full duties and an additional 30% or flat $25 tariff for postal items, while commercial carriers incur a mandatory 10% ad valorem levy. These concurrent measures amplify the cumulative tariff burden on liquid diene rubber imports, effectively raising total duties to 35% or more and underscoring the urgent need for supply chain reengineering and tariff mitigation strategies.

Examining the liquid diene rubber market through the lens of end use applications reveals a nuanced portfolio of growth opportunities and performance demands. In adhesive and sealant formulations, the quest for stronger bonding and faster curing kinetics underscores the need for polymers with finely tuned vinyl content and narrow molecular distributions.
