SITCSection 5
U.S. imports of polycarbonate, alkyd resin & polyester plates, sheets, film, foil & strip (non-self-adhesive, unreinforced) (SITC 58226) totaled $92.6M in April 2026, traded with 69 countries.
Importers of Polycarbonate, Alkyd Resin & Polyester Plates, Sheets, Film, Foil & Strip (Non-Self-Adhesive, Unreinforced) paid $9.5M in duties in April 2026 — an effective duty rate of 14% on $69.1M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataPolycarbonate (PC) sheet and polyethylene terephthalate (PET) film are the commercially dominant products within this heading, serving glazing, optical media, photovoltaic backsheets, and flexible electronics packaging respectively. The grouping of polycarbonates, alkyd resins, and other polyesters under one heading reflects their shared ester-linkage chemistry, though their end-use markets are quite distinct. PET film in particular is a critical substrate for solar panel manufacturing and capacitor dielectrics, sectors where supply-chain origin and specification traceability are closely monitored by buyers.

At the SITC level, both polycarbonate and polyester (including PET) flat forms share this heading. At the US HTS level, the resin type — polycarbonate versus polyethylene terephthalate versus other polyesters — determines the specific 10-digit tariff line. Importers must identify the precise polymer by chemical name or resin code on the commercial invoice to support accurate classification.
A manufacturer's certificate of analysis identifying the resin type (e.g., polycarbonate, PET, or other polyester), thickness, and surface treatment, combined with a mill test report where applicable, provides the evidentiary foundation for classification and AD/CVD scope analysis. Country-of-origin documentation is equally important given active trade-remedy scrutiny on certain polyester film origins.
