Vehicle parts, silencers (mufflers) and exhaust pipes, parts thereof.
Classification of car muffler under HS 8708.92
Car mufflers, also known as silencers, are classified under HS code 8708.92. This code is part of Chapter 87, which covers vehicles other than railway or tramway rolling-stock, and their parts and accessories. Heading 8708 is specifically for parts and accessories of the motor vehicles of headings 8701 to 8705. Subheading 8708.92 is dedicated to silencers (mufflers) and exhaust pipes, as well as parts thereof. The classification is straightforward as it is a named part within the automotive chapter. These components are essential for noise reduction and the safe venting of exhaust gases from the internal combustion engine. The classification includes the entire assembly from the exhaust manifold connection to the tailpipe, provided the components are specifically designed for motor vehicles. The material is usually stainless or aluminized steel, but the classification is driven by the automotive application rather than the metal type.

Codes often confused with 8708.92
Common mistake. Mufflers are often confused with catalytic converters, which are classified under HS code 8421.39 as filtering or purifying machinery for gases. While both are part of the exhaust system, their functions differ significantly. Another error is classifying exhaust pipes as general tubes of iron or steel under Chapter 73; however, because they are shaped and dedicated for vehicle use, 8708.92 is the correct, more specific code.

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).
