Yes — the US schedule distinguishes paper-covered articles by the underlying structural material (plastic, wood, or other), and duty rates can differ across these lines. Importers should confirm the substrate material with the manufacturer and ensure the invoice and packing list reflect both the paper covering and the underlying material to support accurate classification and avoid post-entry corrections.
