Polyetherimide High-Temp Sheets from China
Polyetherimide high-temp sheets are noncellular sheets made from polyetherimide (PEI), used for high-temperature aerospace and electronics applications. They are classified under this tariff item as plates, sheets, film, foil and strip of other plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials. The PEI polymer content meets the 95% threshold, but no specific subheading covers PEI sheets, so they fall under 'other plastics'.
