Standard International Trade Classification
U.S. exports of Non-Cellular Plastic Plates, Sheets, Film, Foil & Strip, NES (Non-Self-Adhesive, Unreinforced) (SITC 58229) totaled $143.5M in August 2026.
Importers of Non-Cellular Plastic Plates, Sheets, Film, Foil & Strip, NES (Non-Self-Adhesive, Unreinforced) paid $4.5M in duties in August 2026, an average duty rate of 9.63% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Non-Cellular Plastic Plates, Sheets, Film, Foil & Strip, NES (Non-Self-Adhesive, Unreinforced) imports of $46.9M in August 2026 ran 19% above the year-to-date monthly average of $39.6M.
Last updated: August 2026 dataActing as the catch-all for non-cellular, non-self-adhesive, unreinforced plastic flat forms not assignable to a polymer-specific heading, this classification captures specialty engineering polymer films — such as polyimide (Kapton), PTFE (Teflon), PEEK, and fluoropolymer films — that lack their own dedicated SITC subheading. The residual "NES" character means classification here requires a two-step analysis: confirming the article is a plastic flat form, and then confirming it does not meet the criteria of any more-specific heading. Specialty films in this category often serve high-value electronics, aerospace, and medical device applications where material certification and traceability are as important as tariff classification.

Polyimide film (e.g., Kapton), polytetrafluoroethylene (PTFE/Teflon) film, PEEK sheet, fluorinated ethylene propylene (FEP) film, and other high-performance engineering polymer flat forms that lack a dedicated polymer-specific SITC heading are the most common products here. The key requirement is that the article is non-cellular, non-self-adhesive, and not reinforced or laminated.
The analysis should start with chemical identification of the polymer resin — if the resin matches a named polymer heading (polyethylene, polypropylene, styrene, vinyl chloride, acrylic, polycarbonate/polyester, or cellulose derivative), that specific heading takes precedence. Only after ruling out all named headings does the article default to this NES residual. A binding ruling request to CBP is the most reliable way to resolve ambiguous cases, and a licensed customs broker can assist with the application.
