SAE 52100 Seamless Alloy Steel Tube
High-precision seamless tube made from SAE 52100 alloy steel, featuring a circular cross-section and tight tolerances ideal for machining into inner or outer races of ball bearings. Its uniform microstructure and hardness after heat treatment make it specifically suitable for bearing manufacturing. Classified under 7304.59.10.00 due to its seamless construction and designation for bearing production.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made from ferritic stainless steel alloy
Ferritic alloys like 410/430 shift to specific stainless headings based on chemical composition.
If pre-machined into bearing races or components
Finished or semi-finished bearing parts move to Chapter 84 as machinery parts.
If welded rather than seamless
Welded construction, even from same alloy, falls under Chapter 73 heading for welded pipes.

Import Tips & Compliance
• Obtain mill certificates confirming SAE 52100 grade and seamless production to prove suitability for bearing manufacture
• Include end-user statements from bearing producers to avoid misclassification as general tubing
• Watch for overlength shipments; ensure compliance with dimensional tolerances to prevent reclassification
