Import Tips
• Structural use may qualify for duty drawback programs—retain engineering drawings showing end application
• Confirm circular cross-section uniformity; non-circular profiles may shift to other 7304 subheadings
• Avoid bulk packaging mislabeled as 'bars' which could lead to Chapter 72 classification errors
