HS Code 3920.91 – Plastics; plates, sheets, film, foil and strip (not self-adhesive), of poly(vinyl butyral), non-cellular and not reinforced, laminated, supported or similarly combined with other materials

HS code 3920.91 is the 6-digit subheading for plastics, plates, sheets, film, foil and strip (not self-adhesive), of poly(vinyl butyral), non-cellular and not reinforced, laminated, supported or similarly combined with other materials. It is used for PVB interlayer film, laminated glass interlayer, automotive windshield film, architectural safety glass film and solar panel encapsulation film.

What HS 3920.91 covers

This code covers non-cellular sheets, films, and strips of poly(vinyl butyral) (PVB), which are not self-adhesive, reinforced, laminated, or combined with other materials. PVB is primarily known for its excellent adhesion to glass, toughness, and optical clarity, making it an essential interlayer in safety glass applications. International trade in PVB is largely driven by the automotive and construction industries, which require safety glass for windshields, architectural windows, and bulletproof applications. Major importers are glass laminators and automotive component manufacturers. Exporters are typically large chemical companies specializing in polymer production. Key considerations include global automotive production cycles, construction booms, and stringent safety regulations that mandate the use of laminated glass in many applications.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
