A516 Grade 70 Hot-Rolled Alloy Steel Plate from Canada

Hot-rolled flat-rolled alloy steel plate meeting ASTM A516 Grade 70 specifications, with thickness exceeding 4.75 mm and width over 600 mm, not in coils and not further worked beyond hot-rolling. Classified under HTS 7225.40.30 as 'other' alloy steel plates of this dimension that do not meet specialized definitions like high-strength or tool steel.

Import Tips

Provide mill test certificates (MTC) verifying alloy composition and mechanical properties to confirm classification as 'other alloy steel'

Ensure product is not further worked (e.g

no polishing or coating) to avoid reclassification under 7225.99

Declare exact thickness and width measurements; common pitfall is mismeasurement leading to incorrect thickness subheading
