U.S. imports of non-cellular, non-reinforced unsaturated polyester plates, sheets & film, nesoi (HS 3920632000) totaled $107K in August 2026, imported from 16 countries.
Importers of Non-Cellular, Non-Reinforced Unsaturated Polyester Plates, Sheets & Film, NESOI paid $44K in duties in August 2026, an effective tariff rate of 40.66% of the $107K imported — duty actually collected as a share of that value, not the published tariff schedule. Non-Cellular, Non-Reinforced Unsaturated Polyester Plates, Sheets & Film, NESOI imports of $107K in August 2026 ran 61% below the year-to-date monthly average of $277K.
Last updated: August 2026 dataUnsaturated polyester (UPR) plates, sheets, and film in non-cellular, non-reinforced, non-laminated form are thermosetting plastic substrates used in corrosion-resistant panels, electrical insulation, and specialty fabrication. The NESOI designation at this 10-digit level means the goods do not fit more specific polyester sheet provisions, making precise material characterization — particularly confirming the resin is unsaturated rather than saturated (PET/PBT) — essential for correct classification. These materials differ from glass-fiber-reinforced polyester composites, which classify elsewhere, and from cellular (foam) polyester sheets. Importers sourcing these substrates for industrial or construction applications should document the resin chemistry to support classification and any applicable antidumping review.

HTS 3920632000 covers non-reinforced, non-cellular unsaturated polyester sheets — meaning no glass fiber, carbon fiber, or other reinforcing material is embedded. Fiber-reinforced polyester composites classify under different headings (typically heading 3921 or chapter 70 for glass-fiber products). The presence or absence of reinforcement is the key classification criterion.
Unsaturated polyesters (UPR) are thermosetting resins that cure irreversibly, distinguishing them from saturated polyesters like PET or PBT, which are thermoplastic. This chemical distinction is determinative for HTS classification: saturated polyester sheets fall under different 10-digit lines within heading 3920, so resin chemistry documentation is essential for accurate entry.
