304 Stainless Steel Billets
Primary cast billets of grade 304 stainless steel, an austenitic alloy containing approximately 18% chromium and 8% nickel. These semi-finished forms are used as input for further hot-working such as extrusion or forging into finished steel products. They are classified under tariff item 7218.10.00 as 'other primary forms' of stainless steel, not yet rolled or shaped into semi-finished products.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the billets have been subjected to primary hot-rolling
Hot-rolled rectangular cross-section semi-finished products of stainless steel fall under this subheading.
If the billets have been further worked beyond primary hot-rolling or forging
Other semi-finished products of stainless steel, such as those roughly shaped by forging, are classified here.
If the billets are rolled into bars or rods of other shapes
Bars and rods of stainless steel, not further worked than hot-rolled, fall under heading 7222.

Import Tips & Compliance
• Ensure the billets are in primary cast form and have not been hot-rolled or further worked, as that would shift classification to semi-finished products under 7218.91 or 7218.99
• Provide a mill certificate showing the chemical composition to confirm the 304 grade and stainless steel definition (≥10.5% chromium)
• Be aware that anti-dumping or countervailing duties may apply to stainless steel from certain countries; check the CBSA's measures in force before shipping
