Last updated: July 2026 dataHot-mix and cold-mix asphalt paving compounds are bulk construction materials used primarily by road-building and infrastructure contractors. Classified under NAICS 324121, these mixtures combine bitumen binders with aggregate and are typically produced close to the point of use, making long-distance international trade relatively limited compared to the raw bitumen feedstock. Import volumes tend to track domestic infrastructure spending cycles and regional aggregate availability rather than global commodity markets.

NAICS 324121 is a production-side industry code used for US economic and trade statistics, while HTS codes govern the tariff treatment of specific imported products. Asphalt paving mixtures imported into the US are classified under relevant HTS chapters covering bituminous mixtures; a licensed customs broker can identify the precise 10-digit line and applicable duty rate for a given formulation.
Because asphalt paving mixtures are heavy, low-value-per-ton products that degrade in quality during long transport, production is overwhelmingly local. Cross-border trade does occur — particularly between the US, Canada, and Mexico — but most import activity in this NAICS category involves the bitumen or asphalt cement feedstock rather than finished paving mixes.
