Import Tips

Include structural grade certifications (e.g

ASTM A653) to support nonalloy steel and coating claims

Avoid overstacking during shipping to prevent coating damage, which could lead to disputes at entry

Check for 'further worked' treatments like painting; those may reclassify per Chapter 72 notes
