HS Code for PP sheet

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.

Products Included

• Solid polypropylene sheets
• PP film for packaging (non-adhesive)
• Polypropylene foil
• Extruded PP strips
• Clear or colored PP plates

Common Misclassification

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.

FAQ

What is the HS code for PP sheet?

The standard HS code for non-cellular, non-reinforced polypropylene sheets is 3920.20.

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.
