HS code for PP sheet: 3920.20
Plastics, of polymers of propylene, plates, sheets, film, foil and strip (not self-adhesive), non-cellular and not reinforced, laminated, supported or similarly combined with other materials.
Classification of PP sheet under HS 3920.20
PP (Polypropylene) sheets are classified under HS code 3920.20 because they are flat-rolled plastic products composed of polymers of propylene. This specific heading is reserved for plates, sheets, film, foil, and strip that are non-cellular and have not been reinforced, laminated, or supported by other materials. To qualify for this code, the PP sheet must not be self-adhesive. The classification follows General Interpretative Rules 1 and 6, focusing on the chemical composition and the physical state of the plastic. These sheets are typically produced through extrusion processes where the molten polymer is forced through a flat die. Because they are unworked beyond surface treatment or being cut into squares or rectangles, they remain in Chapter 39. If the sheets were to be reinforced with a metal mesh or a textile fabric, they would move to heading 3921. The 3920.20 code specifically identifies polypropylene as the primary polymer, distinguishing it from polyethylene or polyvinyl chloride. The material must be in a solid, uniform state throughout its thickness to meet the non-cellular requirement of this heading.

Codes often confused with 3920.20
Common mistake. A frequent error is classifying these sheets under 3921.90. This happens when the sheet is reinforced with a fiberglass mesh or has a cellular (foamed) core. Another common mistake is using 3919.90, which is only for self-adhesive sheets. If the PP sheet is combined with a layer of textile fabric for strength, it may be classified under 3921.19 or 5903 depending on the dominant material by weight. Importers often confuse 3920.20 with 3920.10, which is specifically for polymers of ethylene. It is vital to verify the polymer type through a lab report to ensure the correct propylene-based classification is applied.
Top exporters and importers of HS 392020 (the code used for PP sheet), 2025
In 2025, the largest exporter of HS 392020 (the code used for PP sheet) in UN Comtrade data was China, with 13% of world exports; the largest importer in UN Comtrade data was the United States, with 9.4% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 392020, not only PP sheet.

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).

Questions about PP sheet
What is the HS code for PP sheet?
The HS code for PP sheet is 392020 (Plastics; of polymers of propylene, plates, sheets, film, foil and strip (not self-adhesive), non-cellular and not reinforced, laminated, supported or similarly combined with other materials). The standard HS code for non-cellular, non-reinforced polypropylene sheets is 3920.20.
How do I classify PP sheet for customs?
PP sheet is classified under HS code 392020 — Plastics; of polymers of propylene, plates, sheets, film, foil and strip (not self-adhesive), non-cellular and not reinforced, laminated, supported or similarly combined with other materials. This is a 6-digit subheading level code.
Is a corrugated PP sheet classified here?
No, corrugated PP sheets, often used for signage, are typically classified under 3921.90 because their hollow-core structure is considered a form of cellular or structural modification not covered by 3920.
Which countries are the top exporters of PP sheet (HS 392020)?
In 2025, the top exporters of HS 392020 (the code used for PP sheet) in UN Comtrade data were China ($1.5B, 13% of world exports), Germany ($1.2B) and Italy ($863M). World exports came to about $11.8B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
