Last updated: August 2026 dataMolded or formed from paper pulp into rigid three-dimensional filter elements, these blocks, slabs, and plates serve as depth-filtration media in beverage, pharmaceutical, and industrial liquid-processing applications — a function that sets them apart from flat paper or paperboard in both form and end use. Their classification as paper-pulp articles rather than as paper or paperboard reflects the molded, non-sheet construction. Importers supplying the brewing, winemaking, or pharmaceutical filtration sectors should confirm that the product's pulp composition and structural form align with this heading rather than with filter paper in roll or sheet form.

Filter blocks, slabs, and plates are molded or formed into rigid three-dimensional shapes from paper pulp and are not in roll or sheet form. Flat filter paper in rolls or sheets is classified under a different heading. The physical form — rigid molded article versus flat sheet — is the primary classification determinant.
While paper-pulp filter plates are not food or drug products themselves, those destined for pharmaceutical or food-contact filtration applications may need to comply with FDA regulations governing materials that contact food or drugs. Importers should verify whether the specific end-use triggers any FDA notification or compliance requirement under applicable food-contact or drug-manufacturing regulations.
