Import Tips

Verify galvanization certification and wall thickness measurements to confirm classification under 7306.30.50.31

Include mill test reports showing nonalloy steel composition to avoid reclassification as alloy steel

Ensure outside diameter does not exceed 50.8 mm; common pitfall is mismeasuring OD leading to higher duty brackets
