U.S. exports of Ethylene-Alpha-Olefin Copolymers with Specific Gravity Below 0.94 (HS 390140) totaled $547.1M in August 2026.
Importers of Ethylene-Alpha-Olefin Copolymers with Specific Gravity Below 0.94 paid $1.5M in duties in August 2026, an average duty rate of 1.02% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Ethylene-Alpha-Olefin Copolymers with Specific Gravity Below 0.94 imports of $162.5M in August 2026 ran 19% above the year-to-date monthly average of $136.6M.
Last updated: August 2026 dataEthylene-alpha-olefin copolymers with a specific gravity below 0.94 — a family that includes linear low-density polyethylene (LLDPE) and metallocene-catalyzed grades — are critical inputs for stretch film, flexible packaging, and impact-modifier applications. The density threshold of less than 0.94 is the defining classification boundary separating these materials from HDPE (heading 390120), and a single data-sheet value can shift a shipment between headings. Canada is the leading US supplier, with South Korea and Singapore also significant sources. Importers should confirm specific gravity via certified test results, as density can vary by production lot.

CBP may request a manufacturer's certificate of analysis or an independent laboratory test report confirming the specific gravity of the resin lot. Because density can vary slightly between production runs, importers should maintain lot-level documentation and be prepared to provide test data during a CBP inquiry or audit.
Stretch film, food-contact flexible packaging, and automotive impact modifiers are among the primary end uses. Demand in these sectors can be seasonal or tied to automotive production cycles, so importers often maintain safety stock and diversify across North American and Asian suppliers to manage lead-time risk.
