Last updated: August 2026 dataRoofing felt, saturated sheathing paper, and other bitumen- or asphalt-impregnated paper and paperboard substrates in roll or sheet form are the primary goods in this heading, serving the construction industry as moisture barriers, underlayments, and waterproofing membranes. The defining characteristic is saturation or coating with tar, bitumen, or asphalt — petroleum-derived binders that give the substrate its waterproofing properties. These products are purely industrial materials and do not trigger mandatory admissibility review by food, drug, or agricultural agencies.

The most common applications are roofing underlayments (felt paper beneath shingles), wall sheathing moisture barriers, and waterproofing membranes for foundations and below-grade structures. The degree of bitumen saturation and the base-paper weight determine suitability for each application, with heavier saturated grades used in roofing and lighter grades in wall applications.
Commercial invoices and packing lists should specify the type of impregnant (tar, bitumen, or asphalt), the approximate saturation level or coating weight, and the base-paper substrate. A manufacturer's technical data sheet or material safety data sheet (SDS) is useful supporting documentation, particularly if CBP requests additional information to confirm classification.
