U.S. exports of high-density polyethylene (hdpe) in primary forms (HS 390120) totaled $520.0M in July 2026.
Importers of High-Density Polyethylene (HDPE) in Primary Forms paid $1.9M in duties in July 2026 — an effective duty rate of 17% on $11.1M in dutiable value, based on actual customs collections rather than the published tariff schedule. High-Density Polyethylene (HDPE) in Primary Forms imports of $160.0M in July 2026 ran 33% above the year-to-date monthly average of $120.0M.
Polyethylene with a specific gravity of 0.94 or more — commonly known as HDPE — is a foundational resin for pipe, blow-molded containers, film, and geomembranes. The US tariff schedule subdivides this heading into a viscosity-differentiated line (3901201000, covering material with viscosity ≥1.44) and a residual NESOI line (3901205000), a distinction that matters for resin compounders specifying melt-flow characteristics. Canada and Mexico are the leading suppliers, with South Korea also a notable source; USMCA origin rules can affect duty treatment for North American shipments. Importers should verify whether specific grades fall under any applicable Section 301 measures depending on origin.

HTS 3901201000 covers polyethylene with specific gravity ≥0.94 and a viscosity of 1.44 or greater. Resin that meets the density threshold but falls below the viscosity cutoff is classified under the NESOI line 3901205000. Importers should obtain technical data sheets confirming both parameters before filing entry.
Shipments from Canada and Mexico that satisfy USMCA rules of origin — including applicable tariff-shift or regional-value-content requirements — may qualify for USMCA preferential treatment. A licensed customs broker can confirm whether a specific resin grade and production origin meet those criteria.
