HS Code 3920.99 – Plastics; plates, sheets, film, foil and strip (not self-adhesive), of plastics n.e.c. in heading no. 3920, non-cellular and not reinforced, laminated, supported or similarly combined with other materials

HS code 3920.99 is the 6-digit subheading for plastics, plates, sheets, film, foil and strip (not self-adhesive), of plastics n.e.c. in heading no. 3920, non-cellular and not reinforced, laminated, supported or similarly combined with other materials. It is used for polyimide film, PEEK sheets, PTFE film, ETFE film and polyetherimide (PEI) sheets.

What HS 3920.99 covers

This 'not elsewhere specified' category covers non-cellular sheets, films, and strips of plastics not specifically mentioned in other 3920 subheadings, provided they are not self-adhesive, reinforced, laminated, or combined. This broad category encompasses a vast array of specialized polymers with unique properties such as extreme temperature resistance, specific chemical inertness, optical clarity, or advanced barrier characteristics. These materials are essential for niche, high-performance applications across diverse industries. International trade in these plastics is driven by innovation in advanced materials science and the demand for custom solutions. Importers are often specialized manufacturers in aerospace, medical, electronics, or renewable energy sectors. Exporters are typically advanced polymer producers and converters. The market is characterized by high-value, low-volume trade, focusing on specific technical requirements and cutting-edge applications.

Codes often confused with 3920.99

Common mistake. This is a catch-all, so misclassification often occurs when a specific polymer should have its own code (e.g., 392062 for polycarbonates) but is mistakenly placed here, or when a cellular version is incorrectly classified here instead of 3921.

Top exporters and importers of HS code 392099, 2025

In 2025, the largest exporter of HS code 392099 in UN Comtrade data was Japan, with 31% of world exports; the largest importer in UN Comtrade data was China, with 25% of world imports. Vietnam did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 5.0% of its imports here ($19M, CEPII BACI), so it may rank higher.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
