Last updated: April 2026 dataComponents specifically designed for motor-fan-equipped air conditioning machines — including heat exchangers, fan assemblies, control boards, and refrigerant circuit parts — are classified under this heading, which corresponds to SITC heading 741.5. The aftermarket and OEM supply chains for these parts are deeply integrated with Asian manufacturing, and Section 301 tariffs have materially affected landed costs for components sourced from China. Importers must distinguish dedicated AC parts from general-purpose electrical or mechanical components to support classification, and should document the parent equipment type in commercial invoices.

PCBAs specifically designed and marketed for air conditioning machines generally classify as parts of air conditioning equipment under this heading. However, general-purpose control boards that are not dedicated to AC applications may classify under electronic components headings. The specificity of the part's design and its commercial presentation are the key classification factors; technical datasheets and manufacturer documentation are essential supporting evidence.
Section 301 tariffs apply to a wide range of air conditioning parts imported from China, increasing landed costs for many OEM and aftermarket components. Some importers have responded by qualifying alternative suppliers in countries not subject to these measures, or by seeking product-specific exclusions. A licensed customs broker can help identify which specific HTS subheadings carry Section 301 exposure for a given part.
