Import Tips

Measure and certify exact OD to confirm it falls between 114.3-215.9 mm; slight deviations lead to different statistical breaks

Include end-use statement proving oil/gas pipeline application to distinguish from general casing or tubing

Watch for anti-dumping duties on certain Chinese-origin steel pipes; check current Commerce Department scopes
