These cellular sheets made from expanded polypropylene are lightweight and impact-resistant, commonly used for protective packaging inserts. They fall under HTS 3921.19.00 as cellular plates, sheets, film, foil, or strip of other plastics, specifically non-polyethylene, non-polystyrene cellular polypropylene. The closed-cell structure provides excellent buoyancy and thermal insulation.
