Import Tips
• Confirm the ingots are not considered semi-finished; if they have been hot-rolled or forged, they would fall under a different tariff item
• Provide documentation of the steel's composition to verify it is other alloy steel, not stainless
• Verify whether a certificate of origin is needed for preferential duty treatment
