Import Tips

Verify alloy steel composition meets 'other alloy steel' criteria (not stainless or high-strength low-alloy) with mill test certificates

Provide API 5CT certification documentation to confirm suitability for oil/gas drilling applications

Avoid misclassification by ensuring no external seams; inspect for cold-formed wire exceeding 16mm dimension per Chapter 73 notes
