U.S. imports of brakes, servo-brakes, and parts thereof for motor vehicles (SITC 78433) totaled $519.5M in April 2026, traded with 61 countries.
Importers of Brakes, Servo-Brakes, and Parts Thereof for Motor Vehicles paid $67.1M in duties in April 2026 — an effective duty rate of 26% on $254.0M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataBrake systems and servo-brake assemblies — including disc brakes, drum brakes, ABS modulators, and their component parts — are safety-critical inputs for passenger cars, trucks, and tractors, subject to FMVSS performance standards that affect both OEM and aftermarket importers. The heading spans a wide range of complexity, from raw brake pads and rotors to fully assembled hydraulic or pneumatic brake actuators, and classification at the component level requires careful attention to whether an item is a complete assembly or a part thereof. Trade-remedy exposure under Section 301 has affected sourcing of brake components from certain origins, accelerating supplier qualification in alternative markets.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Brake friction materials and rotors used on vehicles sold in the US must meet FMVSS No. 135 (passenger cars) or FMVSS No. 105 (hydraulic and electric brake systems for other vehicles), which set performance standards for the complete brake system. While CBP does not test individual brake components at entry, importers and distributors bear liability if aftermarket parts contribute to a brake system that fails to meet FMVSS standards. NHTSA can pursue recalls and civil penalties for non-compliant parts in commerce.
Anti-lock braking system modulators and electronic brake control units occupy a classification gray zone. CBP generally classifies them as parts of brakes when their sole or principal function is brake control, but units with broader vehicle stability or electronic control functions may be classified as electrical apparatus or vehicle electronic components under different headings. The specific design, function, and any applicable CBP rulings for similar products should guide the classification decision.
