Last updated: August 2026 dataIntake air filters for internal combustion engines — including panel, cylindrical, and conical filter elements used in passenger vehicles, commercial trucks, agricultural machinery, and power generation equipment — form a distinct aftermarket and OEM parts category separate from oil and fuel filters. The heading's scope is limited to air filtration on the engine intake side; industrial air filtration equipment for general ventilation or process gas cleaning falls under different classifications. Like other automotive components sourced from China, these filters may be subject to Section 301 tariffs, a key landed-cost consideration for high-volume aftermarket importers.

Yes — classification under this heading is based on the filter's function (intake air filtration for an internal combustion engine) rather than its construction material or performance tier. Both standard paper-element OEM filters and reusable high-performance aftermarket filters designed for engine intake air service fall within this heading, provided they are dedicated to that application.
Mixed shipments must be classified line by line at the HTS level: intake air filters and oil/fuel filters occupy separate headings and may carry different duty rates or Section 301 exposure. Each product type should be listed on a separate commercial invoice line with its own HTS code. Commingling without separate line-item identification can trigger customs examination and potential penalties.
