Chrome Steel Needle Rollers for Planetary Gear Bearings
Through-hardened AISI 52100 chrome steel needles for needle bearings in planetary gears of wind turbines and heavy machinery. HTS 8482.91.0040 applies as these are rollers with length-to-diameter ratio >4:1, functioning solely as bearing needles.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported with matching thrust races as a set
Complete thrust needle bearing assemblies classify under finished bearing headings, not parts.
If needles for semiconductor wafer slicing saws
Per statistical notes, parts integral to wafer processing machinery like slicing saws go to Chapter 84 machines.
If bulk steel needles not precision-ground for bearings
Lacking bearing tolerances and surface finish, they become other articles of iron/steel.

Import Tips & Compliance
• Submit hardness test results (58-65 HRC) and dimensional specs to customs for bearing needle verification
• Use HTS statistical suffixes accurately; .0040 specifically denotes needles vs other bearing elements
• Avoid pitfall of classifying heat-treated needles as unfinished steel under 7228—specify bearing end-use

Precision Needle Rollers for Tapered Roller Bearings
These are cylindrical steel needles used as rolling elements in tapered roller bearings for high-load applications in automotive differentials and industrial gearboxes. They fall under HTS 8482.91.0040 as needles, which are specialized parts of ball or roller bearings designed for precise load distribution and minimal friction.
Miniature Needle Rollers for Medical Device Bearings
Ultra-precision needles (0.8-2mm dia.) for miniature bearings in surgical robots and dental handpieces. HTS 8482.91.0040 covers these as needles because of their specialized geometry for compact, high-speed bearing applications.
Cylindrical Needle Rollers for Automotive Transmission Bearings
High-precision cylindrical needles (1-3mm diameter) for needle roller bearings in car transmissions, providing compact high-load capacity. Classified under HTS 8482.91.0040 as bearing needles due to their role as separable rolling elements in thrust or radial bearings.
Drawn Cup Needle Roller Bearing Elements
Loose needle rollers for assembly into drawn cup needle bearings used in robotics and precision instruments. These fall under HTS 8482.91.0040 because they are the dedicated rolling elements (needles) supplied separately for bearing construction.
Heavy-Duty Needle Rollers for Industrial Gearboxes
Large-diameter (5-10mm) case-hardened needles for full complement needle roller bearings in steel mill gearboxes. Classified in HTS 8482.91.0040 as bearing needles due to their exclusive function in radial load support within roller bearing designs.
