The global automotive brake systems market was valued at USD 46.44 billion in 2025 and is projected to reach USD 74.45 billion by 2034, according to Fortune Business Insights. Asia Pacific is expected to account for 48.32% of global brake-system revenue in 2025. Cast iron remains a significant material in steering knuckles, with approximately 20% of the global steering knuckle market by material type in 2024. U.S. Customs and Border Protection classified a front knuckle composed of 93.6% cast iron and a rear knuckle composed of 97.5% cast iron under HTS 8708.80.6000 as suspension parts, rather than under the steering parts heading. The U.S. International Trade Administration lists cast-iron gearbox and miscellaneous automotive part classifications, including 8708407000, 8708407570, 8708995200, 8708995300, and 8409911040.

Material standards are crucial in supplier qualification. ASTM International lists ASTM A159 for automotive gray iron castings, ASTM A602 for automotive malleable iron castings, and ASTM A1095 for high-silicon molybdenum ferritic iron castings used in high-temperature automotive-related applications. These standards define the documentation, material class, and test language that buyers can require during sourcing.
