HS code 8407.34 is the 6-digit subheading for engines, reciprocating piston engines, of a kind used for the propulsion of vehicles of chapter 87, of a cylinder capacity exceeding 1000cc. It is used for passenger car engines (2.0L), luxury car engines (V6/V8), large motorcycle engines (1200cc), sports car engines and SUV engines.
What HS 8407.34 covers
This category encompasses spark-ignition reciprocating piston engines with a cylinder capacity exceeding 1000cc, specifically designed for the propulsion of vehicles in Chapter 87. This includes engines for most passenger cars, larger motorcycles, high-performance sports cars, and heavy-duty recreational vehicles. The international trade in these engines is dominated by major automotive manufacturers and their extensive global supply chains, with engines often being traded between production facilities in different countries. Key exporters are nations with advanced automotive industries, such as Germany, Japan, the USA, and South Korea. Importers are typically vehicle assembly plants worldwide. Critical trade factors include engine technology (e.g., turbocharging, direct injection), fuel efficiency, stringent emissions standards (Euro 6, EPA), and integration with complex vehicle electronics. The market demands high performance, reliability, and compliance with diverse global regulations.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
