HS code for Pulp filter sheets: 4812.00

Paper pulp, filter blocks, slabs and plates of paper pulp.

Classification of pulp filter sheets under HS 4812.00

Pulp filter sheets are classified under HS code 4812.00, which specifically identifies filter blocks, slabs, and plates of paper pulp. This classification is governed by the material composition and the intended industrial application. These products are manufactured by pressure-molding or felting paper pulp (usually wood pulp or other vegetable fibers) into thick, porous forms. Unlike standard paper (Heading 4805) or laboratory filter paper (Heading 4823), these items are characterized by their significant thickness and rigidity, designed for heavy-duty filtration in industries such as beverage production, chemical processing, or oil refining. The classification under 4812.00 is straightforward because it is a 'single-dash' subheading that explicitly names the product form (blocks, slabs, plates) and the material (paper pulp), leaving little room for ambiguity under GRI 1.

Codes often confused with 4812.00

Common mistake. These sheets are often confused with HS code 4823.20, which covers filter paper and paperboard cut to size. The distinction lies in the physical form; 4812.00 is for thick blocks or slabs, whereas 4823.20 is for thinner, flexible paper. Another misclassification occurs with HS code 5911.90, which covers textile products for technical uses. If the filter is made of textile fibers rather than paper pulp, it must be classified in Chapter 59. Furthermore, if the pulp is impregnated with chemicals that change its primary character to a chemical preparation, Chapter 38 might be considered, though this is rare for standard filter sheets.

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).
