Last updated: August 2026 dataRoofing shingles, floor tiles, wall boards, and paving bricks made from asphalt or bituminous compounds are the primary commercial forms in this heading, serving the residential and commercial construction sectors. Asphalt-based building products are classified here based on their material composition rather than their end use, so importers must confirm that the binder is asphalt or a similar bituminous material rather than a mineral cement or resin. Products in this category are generally industrial in nature and do not trigger mandatory admissibility review by food or agricultural agencies. Section 301 tariff exposure may apply to certain asphalt building products sourced from China, depending on the specific HTS line.

The key is the binder: asphalt and bituminous compounds place the article here (66181), while cement, lime, or other mineral binders shift the product to heading 66182. Importers should obtain a material composition certificate from the manufacturer specifying the binder type and percentage, as misidentification of the binder is a common source of classification disputes.
Trade-remedy exposure depends on origin and the specific HTS tariff line. Importers sourcing asphalt shingles or building boards from China should verify whether the applicable 10-digit HTS code is covered by Section 301 tariffs, as coverage varies by product form. A licensed customs broker can confirm current applicability before shipment.
