U.S. imports of clutches and shaft couplings, including universal joints (HS 848360) totaled $43.6M in April 2026, traded with 53 countries.
Importers of Clutches and Shaft Couplings, Including Universal Joints paid $7.3M in duties in April 2026 — an effective duty rate of 20% on $36.7M in dutiable value, based on actual customs collections rather than the published tariff schedule. Clutches and Shaft Couplings, Including Universal Joints imports of $43.6M in April 2026 ran 11% above the year-to-date monthly average of $39.4M.
Last updated: April 2026 dataPrecision-engineered clutches, universal joints, and shaft couplings are foundational drivetrain components for automotive, industrial, and power-generation applications, and Germany leads US import supply under this heading — reflecting that country's strength in high-tolerance mechanical engineering. The US schedule separates clutches and universal joints (8483604040 and 8483604080) from other shaft couplings (8483608000), a distinction that matters because universal joints transmit torque across angular offsets while rigid or flexible couplings connect co-axial shafts. Canada and Japan are also notable suppliers, and goods of Canadian or Mexican origin may qualify for preferential duty treatment under USMCA. Correct classification requires determining whether the article engages/disengages drive (clutch), accommodates angular misalignment (universal joint), or simply connects two shaft ends (coupling).
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A universal joint (8483604080) is specifically designed to transmit rotary motion between two shafts at a variable angle, typically using a cross-and-yoke mechanism. A flexible shaft coupling (8483608000) accommodates minor misalignment or vibration damping but does not permit significant angular variation in the drive axis. The functional design and angular-displacement capability of the article are the key classification criteria.
Goods of Canadian or Mexican origin that meet USMCA rules-of-origin requirements are eligible for preferential tariff treatment, which can meaningfully reduce duty costs given that Canada is among the top suppliers under this heading. Importers should obtain a valid USMCA certification of origin and confirm that the specific 10-digit line qualifies before claiming the preference.
