A302 Grade A Manganese-Molybdenum Alloy Steel Plate from China
ASTM A302 Grade A is a normalized manganese-molybdenum alloy steel plate supplied in widths exceeding 600 mm, primarily used for pressure vessel fabrication. Its molybdenum content of 0.45% to 0.65% by weight classifies it as other alloy steel under heading 72.25, as it does not meet the definitions for stainless, tool, or silicon-electrical steel. The product is hot-rolled and not further worked, falling under tariff item 7225.99.00 as 'Other' flat-rolled alloy steel.

Import Tips
• Ensure the plate width exceeds 600 mm and provide a mill test certificate showing the molybdenum content to support classification under 7225.99.00
• The product is subject to the normal MFN duty rate; verify if a free trade agreement (e.g
• CUSMA, CPTPP) applies to reduce or eliminate duties
• Declare the steel as 'other alloy steel' and be prepared for CBSA verification of the alloy composition
