U.S. exports of High-Density Polyethylene (HDPE) in Primary Forms (SITC 57112) totaled $539.9M in August 2026.
Importers of High-Density Polyethylene (HDPE) in Primary Forms paid $1.1M in duties in August 2026, an average duty rate of 0.83% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataClassified by its specific gravity of 0.94 or more, this grade of polyethylene corresponds to high-density polyethylene (HDPE), the workhorse resin of pipe, bottle, and film manufacturing. HDPE's stiffness-to-weight ratio and chemical resistance make it a primary input for packaging, construction conduit, and industrial containers. Imports of this resin in primary forms — pellets, granules, or powder — are subject to standard customs classification scrutiny to confirm density meets the 0.94 threshold, which separates it from lower-density ethylene polymer headings.

Importers typically provide a manufacturer's certificate of analysis or technical data sheet confirming the resin's specific gravity. Customs may request laboratory testing if the declared density is disputed, since the threshold determines which SITC/HTS heading applies and the corresponding duty treatment.
Primary forms include pellets, granules, powders, flakes, and similar bulk resin presentations before further fabrication. Sheets, films, tubes, or molded articles are classified elsewhere, so the form of the shipment is a key classification factor.
