Import Tips

Obtain mill test certificates verifying alloy steel composition and API 5L compliance to avoid reclassification

Ensure documentation proves use in oil/gas pipelines; general tubing may shift to 7305.19

Check diameter measurement standards (actual OD must exceed 16 inches) to prevent customs disputes
