Import Tips

• Verify alloy steel composition meets ASTM A335 or API 5CT standards with mill test certificates to ensure classification under 7305.20.80.00

• Provide drilling end-use documentation like purchase orders to avoid misclassification as general line pipe

• Confirm external diameter exceeds 406.4 mm via precise measurements to prevent reclassification to smaller diameter headings
