A516 Grade 70 Pressure Vessel Steel Plate from United States
ASTM A516 Grade 70 is a flat-rolled alloy steel plate with a width exceeding 600 mm, used for pressure vessels and boilers. Although often considered carbon steel, it contains alloying elements such as manganese and silicon that may push it into the 'other alloy steel' category if thresholds are met. As a hot-rolled product not further worked, it is classified under tariff item 7225.99.00 as 'Other'.

Import Tips
• Confirm the chemical composition to determine if it qualifies as alloy steel; if manganese is below 1.65% and other elements are within carbon steel limits, it may fall under heading 7208 instead
• Provide a mill certificate with full composition analysis
• If classified as alloy steel, ensure width exceeds 600 mm
