U.S. exports of non-cellular unsaturated polyester plates, sheets, film, foil & strip (HS 392063) totaled $1.5M in August 2026.
Importers of Non-Cellular Unsaturated Polyester Plates, Sheets, Film, Foil & Strip paid $107K in duties in August 2026, an effective tariff rate of 15.80% of the $679K imported — duty actually collected as a share of that value, not the published tariff schedule. Non-Cellular Unsaturated Polyester Plates, Sheets, Film, Foil & Strip imports of $679K in August 2026 ran 38% below the year-to-date monthly average of $1.1M.
Last updated: August 2026 dataUnsaturated polyester (UPR) flat forms in non-reinforced, non-cellular configuration serve niche applications in corrosion-resistant linings, decorative panels, and specialty casting stock — distinct from the far more common glass-fiber-reinforced polyester composites that classify elsewhere. The US schedule separates flexible forms (3920631000) from non-flexible NESOI (3920632000), a distinction that matters for end-use in flexible packaging versus rigid fabrication. Canada is the leading supplier, with China and Turkey also significant sources. Importers should take care that unreinforced UPR sheet is not confused with fiber-reinforced polyester panels, which classify under different headings.

Heading 392063 explicitly excludes reinforced forms. FRP panels — where glass fiber is embedded in the polyester matrix — classify under heading 3921 as reinforced plastic sheets. Customs will look at the physical construction: if any fibrous reinforcement is present, the product moves out of 3920 entirely. Lab analysis or manufacturer's technical data sheets are often needed to confirm the absence of reinforcement.
Primary applications include corrosion-resistant tank linings, decorative casting blanks for countertop fabrication, and specialty electrical insulation substrates. The flexible subheading (3920631000) also appears in certain specialty packaging and membrane applications where UPR's chemical resistance is valued over more common polyolefin films.
