Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If ground, polished, or chemically treated surface
Surface treatments per chapter note (polishing, phosphatizing) classify as finished bars under 7222.30 rather than semi-finished.
If cross-sectional area exceeds 232 cm²
Same circular stainless semi-finished heading but statistical break at 232 cm² area separates subheadings.
If not stainless steel alloy
Non-stainless semi-finished iron/steel products fall under Chapter 72 headings 7207-7208, not stainless-specific 7218.

Import Tips & Compliance
• Submit chemical analysis certificates proving molybdenum content for 316L classification and stainless steel status
• Calculate and document exact cross-sectional area; areas approaching 232 cm² risk scrutiny
• Avoid clad or coated billets to prevent reclassification under further worked provisions
