Stainless Steel Seamless Hollow Bar 304 Grade
A seamless hollow bar made from 304 stainless steel with a circular cross-section, designed for use in machinery components. It falls under HTS 7304.49.0015 as a hollow profile of stainless steel, not suitable for drilling or threading, distinguishing it from tubes or pipes. These bars are precision-formed without welds for high-strength applications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If alloy steel content exceeds specified limits
Higher alloy stainless steels may shift to Chapter 72 headings for other bars and rods.
If cold-drawn and suitable for drilling or threading
Bars finished for machining into bores or threads are classified separately from seamless hollow profiles.
If imported as finished mechanical tubing
End-use as precision tubing rather than raw hollow bar changes classification to welded or seamless tubes.

Import Tips & Compliance
• Verify seamless construction via mill test certificates to avoid misclassification as welded products under 7306
• Ensure accurate measurement of wall thickness and outer diameter to confirm it's a hollow bar, not a tube
• Label with exact steel grade (e.g
• 304) and provide chemical composition reports for customs valuation
