Cold-Drawn Alloy Steel Bearing Tube 52100
Seamless cold-drawn tube made from 52100 alloy steel, with precise dimensions and high surface finish suitable for machining into inner or outer races of ball bearings. This falls under HTS 7304.51.10.00 due to its circular cross-section, cold-formed process, and specific design for bearing manufacture. The material's high carbon-chromium composition ensures durability under rolling contact stress.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not specifically documented for bearing use
Lacks proof of bearing manufacture suitability, defaults to other cold-drawn alloy steel tubes.
If hot-rolled rather than cold-drawn
Hot-formed tubes shift to Chapter 72 hollow bar provisions, different processing method.
If imported pre-machined as bearing parts
Finished or semi-finished bearing components classified by function in Chapter 84, not as raw tubes.

Import Tips & Compliance
• Provide mill test certificates verifying 52100 alloy composition and seamless cold-drawn process to customs for classification verification
• Ensure dimensional tolerances meet bearing industry standards (e.g
• ISO 286) to avoid reclassification as general-purpose tubing
