U.S. exports of Other Ethylene Polymers in Primary Forms (N.E.S.) (SITC 57190) totaled $619.6M in August 2026.
Importers of Other Ethylene Polymers in Primary Forms (N.E.S.) paid $5.3M in duties in August 2026, an average duty rate of 3.05% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Other Ethylene Polymers in Primary Forms (N.E.S.) imports of $187.3M in August 2026 ran 21% above the year-to-date monthly average of $155.2M.
Last updated: August 2026 dataA residual catch-all for ethylene-based polymers not elsewhere specified, this heading captures specialty resins such as linear low-density polyethylene (LLDPE), ultra-high-molecular-weight polyethylene (UHMWPE), and certain ethylene copolymers that do not fit the density or comonomer criteria of more specific headings. Correct classification here requires ruling out all named ethylene polymer categories first, making it a heading where classification disputes and binding ruling requests are relatively common. Trade professionals should document the resin's density, comonomer identity, and molecular weight to support the N.E.S. claim.

The key differentiators are specific gravity and comonomer composition. Resins with specific gravity of 0.94 or more fall under the HDPE heading; those with named comonomers like vinyl acetate have their own headings. A resin lands in the N.E.S. category only after it is confirmed to fall outside all those named criteria.
For novel or borderline resins, requesting a binding ruling from US Customs and Border Protection is strongly advisable. The N.E.S. designation is residual by definition, and CBP may reclassify a shipment if a more specific heading is found to apply, potentially triggering duty adjustments or penalties.
