AISI 304 Stainless Steel Billet
A square solid section of AISI 304 stainless steel, typically 100-150mm across, used as primary input for forging or rolling into bars and sheets. Classified under HTS 7218.99.00 as a semi-finished product in primary form, not yet reduced to bars, rods, profiles, or wire. Meets Chapter 72 definitions for stainless steel semi-finished products other than ingots.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in ingot form
Ingots or irregularly shaped primary forms fall under the specific ingot subheading rather than 'other' semi-finished products.
If rolled into bars/rods with rectangular cross-section >80mm
Once hot-rolled and worked to bar dimensions, moves from semi-finished Chapter 72.18 to finished stainless bars in heading 7222.
If not stainless steel (under 10.5% chromium)
Non-stainless semi-finished steel products classify under 7207, as Chapter 72 prioritizes stainless in 7218-7229.

Import Tips & Compliance
• Provide mill test certificates confirming stainless steel composition (min 10.5% chromium); declare exact dimensions to avoid reclassification as bars under 7222; watch for anti-dumping duties on certain stainless billet origins
