U.S. imports of radiators for motor vehicles (HS 870891) totaled $124.5M in August 2026, imported from 53 countries.
Importers of Radiators for Motor Vehicles paid $15.8M in duties in August 2026, an effective tariff rate of 12.66% of the $124.5M imported — duty actually collected as a share of that value, not the published tariff schedule.
Last updated: August 2026 dataEngine cooling radiators and their parts — including radiator cores (8708917510) and cast iron components (8708917000) — are classified across eight 10-digit lines that separate complete radiator units from parts and distinguish agricultural tractor applications from other motor vehicles. Mexico and Canada lead supply, reflecting North American assembly plant proximity, with China also a notable source subject to Section 301 tariffs. Radiator cores, which are often traded separately as replacement components, warrant particular attention to classification given their distinct line from complete assemblies.

No. The US schedule provides a dedicated line for radiator cores (8708917510), separate from complete radiators for agricultural tractors (8708911000) and other vehicles (8708915000). A radiator core — the heat-exchange matrix of tubes and fins without tanks or fittings — is a discrete part, and its separate classification can affect both duty treatment and trade remedy exposure. Importers should confirm the article's completeness before selecting a line.
Mexico's position as the leading supplier reflects the concentration of Tier 1 and Tier 2 automotive cooling system manufacturers that have established production near US assembly plants under the integrated North American supply chain. USMCA rules of origin for automotive parts incentivize regional production, and the short transit times support just-in-time delivery requirements common in OEM radiator supply agreements.
