Last updated: April 2026 dataTarred macadam is a road-paving aggregate in which crushed stone is pre-coated or mixed with tar binders, classifying under a single US tariff line (2517300000). Its primary commercial role is in highway and infrastructure construction, where it competes with asphalt concrete mixes. Canada dominates US import supply given cross-border infrastructure project logistics, with the United Kingdom a secondary source. Importers should confirm the tar-binder composition, as products using bitumen rather than coal tar may be reclassified under a different heading.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Tarred macadam (HTS 2517300000) consists of stone aggregate pre-coated or mixed specifically with tar (coal-tar derived binders). Products bound with bitumen (petroleum-derived) are generally classified elsewhere in Chapter 27 or Chapter 68, so the binder type is the critical classification determinant. Consult a licensed customs broker if the binder composition is ambiguous.
Importers from Canada should provide a commercial invoice specifying the aggregate type, binder composition, and country of origin to support USMCA origin claims. A certificate of origin and any applicable safety data sheets for the tar component are standard supporting documents.
