Last updated: August 2026 dataUncoated filter paper and paperboard — along with felt paper and paperboard in roll or sheet form — serve as critical inputs across laboratory, food-processing, and industrial filtration sectors. The defining characteristic is the absence of any coating or impregnation, which preserves the substrate's natural porosity and absorption capacity. Felt paper in this heading is distinguished from filter paper by its denser, matted fiber structure, making it suitable for cushioning, sealing, and acoustic applications in addition to filtration.

Filter paper is characterized by controlled porosity designed to separate solids from liquids or gases, while felt paper has a denser, non-woven fiber structure used for cushioning, sealing, or acoustic dampening. Both are uncoated and traded in rolls or sheets under this heading, but end-use documentation and fiber composition may be requested by customs to confirm classification.
Filter paper that comes into direct contact with food during processing may be subject to FDA food-contact material regulations. Importers should obtain supplier declarations confirming compliance with applicable food-contact standards and retain those records for potential CBP review.
