AISI 4140 Alloy Steel Plate from United States
> AISI 4140 is a chromium-molybdenum alloy steel plate, flat-rolled and exceeding 600 mm in width. It is commonly used in machinery and structural applications due to its toughness and fatigue resistance. This product does not fall under any of the specific alloy steel subheadings (e.g., electrical, high-speed, or stainless), so it is correctly classified under the residual "Other" item.

Import Tips
• > Verify the plate's width and thickness to confirm it meets the flat-rolled product definition
• Provide a certificate of analysis to the CBSA showing chromium and molybdenum percentages
• Be aware that if the plate is further worked (e.g
• cut to shape), it may still be classified here if it retains the character of a flat-rolled product
