U.S. imports of balls, needles, and rollers for ball or roller bearings (HS 848291) totaled $10.2M in June 2026, traded with 35 countries.
Importers of Balls, Needles, and Rollers for Ball or Roller Bearings paid $1.7M in duties in June 2026 — an effective duty rate of 17% on $10.0M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Rolling elements—the precision-ground balls, needles, tapered rollers, spherical rollers, and cylindrical rollers that are the functional core of bearing assemblies—are classified separately here when imported as components rather than as part of a finished bearing. Japan leads US import supply, with China and India also significant sources; Chinese-origin rolling elements are subject to Section 301 tariffs. The eight 10-digit lines segment by both element geometry and material, with alloy steel balls (8482910010) distinguished from non-alloy steel balls across two additional lines, and separate lines for needles (8482910040), tapered rollers (8482910050), spherical rollers (8482910070), other cylindrical rollers (8482910080), and residual roller types (8482910090). Grade and surface finish tolerances—governed by ABMA and ISO standards—are critical commercial specifications that affect both pricing and admissibility into precision bearing production.

The US schedule separates alloy steel balls (8482910010) from non-alloy steel balls across distinct 10-digit lines. The distinction turns on the steel's chemical composition as defined in the HTS chapter notes—alloy steel contains specified minimum quantities of alloying elements such as chromium, manganese, or molybdenum. Importers should obtain mill certificates confirming the steel grade to support the correct line selection.
Rolling elements imported separately—whether for OEM production, aftermarket assembly, or MRO repair stock—classify under 8482.91 regardless of their intended end use, provided they are not already incorporated into a bearing assembly. End use does not change the classification; what matters is the physical condition of the goods at the time of importation. Finished bearings, even partially assembled, would be classified under the appropriate bearing heading.
