U.S. exports of Polyether Resins (Other Than Polyacetals), Primary Forms (SITC 57419) totaled $104.1M in August 2026.
Importers of Polyether Resins (Other Than Polyacetals), Primary Forms paid $7.0M in duties in August 2026, an average duty rate of 13.90% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataPolyether resins excluding polyacetals encompass a commercially diverse group — polyphenylene oxide (PPO), polyethylene glycol (PEG), polypropylene glycol (PPG), and polytetramethylene ether glycol (PTMEG) — each serving distinct end markets from engineering plastics blending to polyurethane prepolymer synthesis. The specific polyether type and molecular weight are the defining specifications for both end-use suitability and tariff classification. PTMEG, a key input for spandex fiber and thermoplastic polyurethane, is among the most actively traded grades in this heading.

Molecular weight determines whether a polyether polyol is classified as a primary-form polymer or as a chemical intermediate. High-molecular-weight polyether polyols used as polymer building blocks typically fall under polymer headings, while low-molecular-weight grades may be classified as chemical compounds. Importers should provide the number-average molecular weight and intended end-use to support classification.
Polytetramethylene ether glycol (PTMEG) is the primary raw material for spandex (elastane) fiber and thermoplastic polyurethane (TPU) elastomers. US demand is closely tied to apparel, athletic wear, and automotive interior production cycles, making PTMEG import volumes a useful leading indicator for those downstream sectors.
