Mexico Large Piston Engines (HS 840734) 2025 July Export: Market Concentration

Geographic Concentration and Dominant Role

Mexico's Large Piston Engines (HS Code 840734) export profile for 2025 July is overwhelmingly concentrated, with the United States accounting for nearly two-thirds of the total export value (63.79%) and almost three-quarters of the total weight (73.64%). The fact that the value share is slightly lower than the weight share suggests these shipments to the US consist of a mix of engine types, including both higher-value and more standard, heavier units.

Partner Countries Clusters and Underlying Causes

The data reveals three clear partner clusters. The first is the dominant US market for finished automotive engines. The second includes Canada and South Korea, which together take over a third of the export value; these likely represent trade within established North American OEM supply chains and specialized, high-value technical partnerships. The third cluster consists of smaller, diverse markets like Spain, Vietnam, Brazil, and Germany, which point to niche aftermarket part sales or specific industrial equipment replacements, characterized by very low shipment frequencies and quantities.

Forward Strategy and Supply Chain Implications

For exporters, the extreme reliance on the US market requires careful management of new compliance rules. Starting July 7, 2025, shipments of these engines require an Automatic Export Notice, which takes a minimum of 7 days to process [APA Engineering]. This new rule makes supply chain timing less flexible. Companies must factor this lead time into their logistics planning to avoid costly delays at the border, especially for just-in-time automotive manufacturing streams.
