U.S. imports of petroleum resins, coumarone-indene resins & polyterpenes in primary forms (HS 391110) totaled $14.1M in April 2026, traded with 18 countries.
Importers of Petroleum Resins, Coumarone-Indene Resins & Polyterpenes in Primary Forms paid $2.9M in duties in April 2026 — an effective duty rate of 20% on $14.5M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataPetroleum resins, coumarone-indene resins, and polyterpenes are widely used tackifiers in hot-melt adhesives, rubber compounding, and road-marking paints, making them critical inputs for packaging and construction supply chains. South Korea is the dominant US supplier under this heading, followed by China and France; South Korean producers have built large-scale C5 and C9 hydrocarbon resin capacity that underpins their export position. Imports from China carry Section 301 tariff exposure, a factor that has reinforced South Korea's competitive advantage in the US market.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Petroleum resins are derived from cracked petroleum fractions (C5 or C9 streams), while coumarone-indene resins originate from coal-tar distillates. Both are classified under the same 10-digit line (3911100000) in the US schedule, so the distinction matters primarily for technical specifications and end-use qualification rather than for duty purposes.
Hot-melt and pressure-sensitive adhesive manufacturers are the largest consumers, followed by rubber compounders (for tire and footwear applications) and road-marking paint producers. Demand tends to track construction activity and packaging output, giving imports a degree of cyclicality tied to those sectors.
