Import Tips

• Verify seamless manufacturing process with mill test certificates to confirm classification under 7304, not welded tubes in 7306

• Ensure wall thickness and OD measurements are documented precisely, as deviations can shift to adjacent subheadings

• Obtain hydrostatic test reports for pressure-rated applications to satisfy customs and end-user specifications
